Page 5 Unpacking and checking your Kymera Read this User’s Manual from start to ﬁnish, paying special a[enTon to the secTon Ttled ”Ba[ery handling” Remove the Kymera from its packaging and carefully inspect the exterior for any damage Lie the board on a kayak stand, table or workhorses so that it is not lying directly on the ground or sand This will ensure that no debris is sucked into the impeller when you test the opera=on of the board. Open the front hatch and remove the bubblewrapped ba[ery charger box and maintenance kit if present from the ba[ery tray (if not sent separately) and all packaging materials (foam, tape) from inside the board You can open the front hatch by pushing down on the top end of the rectangular black tab, hold the tab and turn it 90 degrees in either direc=on. Open the glove box and remove all the contents, including the carry strap, ﬂush adapter and hose connector, and put aside somewhere safe The glove box is the cavity inside the front hatch - turn the round glove box cover an=-clockwise to open it. Inspect all board components, nuts and bolts to ensure they are all ﬁrmly secured (but not overTght). Ensure that the jet pump is free from packing materials, debris and safely away from your hands and feet and those of any observers. Ensure that all the nuts, bolts and screws which hold the Kymera together are secured ﬁrmly, especially the following: the bright-coloured thumb bolts holding the clear cover on the electronics • housing – do not over=ghten – use your thumb and foreﬁnger to =ghten ﬁrmly the screws holding the four d-rings to the outer edges of the board • the screws securing the grill and ride plate underneath the board • the rivets underneath the board securing the chassis to the board • the bolts and nylon nuts securing the rear round hatch to the board • Open the lower hatch by pulling the black tab upwards and turn the large round plasTc two-piece coupler by hand to ensure the drive shad moves freely, then close the hatch by simply pushing it down ﬁrmly The coupler in this photo is bright green. It looks a bit like a big plas=c clam. Yours will be black. Remove the charger from its box...
Page 6 Unpacking and checking your Kymera Do not proceed without having reviewed the whole secTon ”Ba[ery handling” p9 Open Kymera package #2 and remove the ba[ery from the hard carry case Use the carry handle on the baFery to remove it from the hard carry case.  Check for any signs of damage to the hard carry case or baFery before charging or using the baFery. Be CAREFUL! The baFery must NEVER be dropped! Change the ba[ery following the procedure ”Ba[ery charging” p11 When the ba[ery is fully charged, move the power cable inside the front hatch out of the way and insert the ba[ery so it is fully seated back into the ba[ery tray Lock the ba[ery in place with the ba[ery tray handle, plug in the power cable and acTvate the ba[ery Listen for a few beep(s) and verify that the baFery meter display turns on.  Wait for ten seconds to allow the computer to fully boot up. Failure to do so may result in non-ac=va=on or incorrect trigger seUng. Double-check that nothing is obstrucTng the impeller and gently pull the thro[le trigger to verify that the motor engages When the board is ﬁrst turned on there can be a small lag before the motor ac=vates. Retry if the motor doesn’t engage the ﬁrst =me but don’t pull the trigger hard – the motor should never be run hard when the board is out of the water. If it s=ll won’t ac=vate, did you wait 10 seconds before pulling the trigger? If not, turn oﬀ the baFery for at least 5 seconds and repeat the process.  DeacTvate the ba[ery, remove the power cable, unlock the ba[ery tray handle, remove the ba[ery, wipe it down and return it to the hard carry case You unlock the baFery tray handle by pulling the silver knob on the end of the handle outwards and pulling the handle down. Carefully close and secure both tabs on the hard carry case.  Close and lock the front hatch of the board. Your board is ready for acTon! Geing to know your Kymera Board topside Page 6...
Page 7 Unpacking and checking your Kymera The front hatch provides access to the forward half of the board’s interior. This hatch is used to install the baFery, access the glove box and check the baFery meter, and clean the board aber use. The front hatch lock is opened by pushing down on the top end of the rectangular black tab, hold the tab and turn it 90 degrees in either direc=on. The trigger throFle is how you make the board move! Just pull the trigger to make it go, part way in for slow and all the way in for fast. When you want to stop, release the trigger throFle. The D-rings on both sides of the board are used to aFach the shoulder carry strap, secure the board onto a roof rack or aFach a body board wrist strap – or anything else, for that maFer!  If using a carry bag to transport the board long distances, ensure you remove all four D-rings with an Allen key ﬁrst, so they don’t put holes in the carry bag! The electronics box (ebox) cooling line outlet expels water which enters the board via the jet nozzle and runs through the board to cool the ebox.  Page 7...
Page 8 Unpacking and checking your Kymera Make sure that this outlet is expelling water (to the led) within a few metres of running the board. If it is not, the cooling line may be blocked or disconnected and the power will cut out to protect the electronics from overheaTng, potenTally leaving you stranded. An excessive build-up of pressure in the cooling system caused by blocked cooling lines can also burst the cooling lines and result in damage to the electronics. The motor cooling line outlet expels water which enters the board via the jet nozzle and runs through the board to cool the motor.  Make sure that this outlet is expelling water (to the right) within a few metres of running the board. If it is not, the motor is not being cooled, which may result in the power cuing out to protect the motor from overheaTng, potenTally leaving you stranded. The rear hatch provides access to the drive system for cleaning and maintenance. Here you can clean the rear interior of the board aber use, grease the drive shab, and adjust or replace the coupler. This also provides access to periodically maintain the exit bearings. Page 8...
Page 9 Unpacking and checking your Kymera Board underside and tail The water intake grill protects the impeller from damage from large items of debris, and prevents any body parts from going anywhere near the impeller. The jet assembly is located under the ride plate. The hull has a self-draining ball-type plug, shown here draining water (boFom right of photo). This plug should be checked for water ﬂow regularly, or if ever an excessive amount of water pools inside the board.  Make sure that this plug stays clear of debris – remove, clear and reinstall if required. Otherwise, it may drain slowly or allow excessive amounts of water to enter the hull. The board should never be run with an excessive amount of water inside. You can safely stand the Kymera on its tail as shown to drain excess water from the hull and to store the board.  Make sure that you don’t sit the board on any obstruc=on which could damage the jet nozzle or the water cooling lines. Jet nozzle The rear drive shab grease nipple is accessed through the centre of the jet nozzle. Always use the grease gun with a long shab quick release coupler, provided in the maintenance kit. Front hatch interior The front hatch provides access to the brains of the opera=on, the electronics housing, as well as access to the baFery tray and the glove box (located inside the front hatch lid).  Ensure that the thumb screws holding down the cover of the electronics housing always remain screwed =ght. Loose thumbscrews may reduce the waterproofness of the housing. Do not open the ebox. This will void your warranty and may nega=vely aﬀect the waterprooﬁng of the housing, resul=ng in poten=al failure of one or more components in the ebox. The read-and-black power lead to the baFery is seen here on the leb. The electronics housing contains the baFery meter. The ebox layout and baFery meter may vary from the one shown. Rear hatch interior The rear hatch provides access to the coupler, drive shab and the motor. The rear hatch is aFached to the board with a coil lead to prevent loss.  Remember to close the rear hatch before transpor=ng your board on your roof racks! It’s easy to forget! You can access the forward drive shab grease nipple through the rear hatch. It is located inside the board to the leb of the image shown below. Use a grease gun with a ﬂexible hose and long shab quick release coupler provided in the maintenance kit to grease that part. Page 9...
Page 10 Unpacking and checking your Kymera Ba[ery handling Failure to follow these instrucTons may result in permanent ba[ery damage, electrocuTon, ﬁre and/or explosion. Ba[ery overview The Kymera baFery is a 51.8V normal charge 30Ah lithium baFery. The baFery contains an advanced baFery management system (BMS) which protects the baFery cells, the board and the rider from danger. Ba[ery inspecTon Your baFery will arrive par=ally charged, usually between 53V and 55V or around 70%. Charge your baFery before use, using only a Kymera- supplied baFery charger. Before every use, inspect the baFery for any signs of damage or defect. If any are found please take photos and send to support@kymerabodyboard.com Ba[ery warnings Always inspect the baFery case, switch and connectors for any signs of damage and do not use if any damage is found Always install the baFery just before opera=on and remove immediately aber Never allow your baFery to become submerged Always remove the baFery prior to opening the rear hatch Never transport your board with the baFery installed Never aFempt to use a baFery which shows signs of cracking or other damage Never aFempt to use a baFery which is emiUng a smell of lithium gas or smoke Never open the rear hatch when the baFery is installed Never open the baFery Never leave your baFery discharged. Failure to maintain at least 40% charge will result in permanent damage and will void your warranty Always check the baFery charge levels at least every 60 days and recharge to a storage level of 55V to maximize baFery life Never store your baFery fully charged for more than (2) week. Never clean your baFery with high pressure water. Page...
Page 11 Unpacking and checking your Kymera Ba[ery charger Your baFery charger is a 58.8V @ 18A output lithium baFery charger. It comes with the correct input plug for your country and Kymera output plug. Like all electronic equipment, the baFery charger supplied with the Kymera requires a good quality power supply to avoid any damage. If you are unsure, it will be worthwhile buying a power line ﬁlter rated for 1500w+ to ensure that any power issues don’t damage the baFery charger or baFery. The mains power lead is located at the rear of the charger. The front panel includes the baFery output cable (with a yellow end), fan and red/green indicator light The charger will recharge a baFery from empty to full in around 90 minutes. Ba[ery charger warnings Failure to keep charger contacts free of dirt / debris will result in permanent . damage to the plug and or baFery connector. Always charge your Kymera baFeries using only the included charger. Never charge non-Kymera baFeries with this charger Always choose a safe baFery charging loca=on with good air ﬂow, ven=la=on and away from pets and people Never leave your charging baFery unaFended Always recharge your baFery aber each use to the appropriate charge level Never leave your fully charged baFery connected to the baFery charger for an extended period of =me Never leave your baFery fully charged for longer than (1) week To maintain op=mal baFery health, let the baFery rest for 10 minutes aber charging before using it Connect your charger directly to the mains outlet wherever possible. The 2 hour charger requires 1000W+. A standard household power circuit can support only (1) 2 hour charger. If you are unsure of your household power capacity, consult a qualiﬁed electrician. If an extension cord is needed to locate the baFery / charger in a safe charging loca=on, use a heavy duty power extension cord no longer than 10b long. Do not use power strips or other methods to connect more than (1) charger  to a power circuit, even if the power circuit supports more than 10A –  the power strip may not! Page...
Page 12 Unpacking and checking your Kymera Ba[ery charging Iden=fy a secure loca=on away from all ﬂammable materials with an appropriate power outlet. Ensure the power outlet is switched oﬀ. Verify the charger input voltage shows the correct voltage, for your applica=on. It will be indicated by a red box next to either 100V~130VAC or 200V~240VAC. Ensure you have good quality power supply which is not likely to spike or brown out. If in doubt, install a power line ﬁlter. Low quality generators with insuﬃcient inverters can result in charger failure. Turn the wall outlet switch oﬀ and connect the charger to the wall outlet or power line ﬁlter (for situa=ons where the wall outlet does not provide good quality power). With the baFery power switch in the oﬀ posi=on, connect the charger to the baFery with the cable with the yellow plug (shown on the leb in this photo) Make sure the plug is correctly oriented – there’s only one way it can be connected. With everything fully connected, switch on the wall power point. The charger light should turn GREEN, showing that the baFery is not yet connected (as it is turned oﬀ). Switch on the baFery. The charger light should now turn RED, indica=ng that it is charging the baFery. The light will remain RED un=l the baFery is fully charged, then it will turn GREEN. THE FIRST TIME YOU CHARGE YOUR BATTERY Leave the baFery connected for a further hour to give the baFery cells the opportunity to ’balance’, maximising the life of your baFery and minimise the chance of any baFery problems. You can now switch oﬀ the baFery and the wall outlet, disconnect the baFery from the charger, and then the charger from the wall. Your baFery is now ready for use. Return it to its hard carry case and transport with care. Ba[ery installaTon Page...
Page 13 Unpacking and checking your Kymera Open the front hatch and gently insert baFery tail ﬁrst into the tray. Slide the baFery back un=l the baFery sits ﬂat in the tray. Rotate the baFery locking bar to its full upright and locked posi=on. (Note the locking pin located on the side used to release the handle to remove the baFery aber use.) With the power switch oﬀ, locate the power plug and insert into the baFery receptacle, making sure the plug is fully seated. With the bar locked and plug fully installed, switch the baFery power switch to the ON posi=on. You will hear a series of tones during the start up sequence. Do not pull the trigger un=l the tones have stopped and the computer has ﬁnished boo=ng up. We recommend you wait 10 seconds. If the throFle doesn’t respond aber a few seconds (maybe not enough =me elapsed between turning the power on and tes=ng the throFle), turn OFF the baFery, wait 10 seconds and retry. Page...
Page 14 Unpacking and checking your Kymera Ba[ery storage The baFery charge level should then be checked at least every 60 days to ensure it remains above 40% (52V). Always store your baFery in a cool dry secure area, and out of the reach of children. When storing your baFery, the life can also be drama=cally aﬀected by the storage temperature. Page...

Unpacking and checking your Kymera Riding your Kymera Know before you go It is the operator’s sole responsibility to know and follow any and all rules and regulaTons related to operaTon in any given waterway. Each state, council or speciﬁc waterway can have their own regulaTons, so it’s criTcal to contact the proper authoriTes prior to operaTon. If you should need help with classiﬁca=on or clariﬁca=on about the Kymera to gain approval for your local waterway, please contact Kymera support@kymerabodyboard.com or call and we’ll be happy to help. New board break in – IMPORTANT! DO NOT OPERATE YOUR BOARD OUT OF THE WATER. This is par=cularly important prior to break in. Ensure you have checked your board thoroughly and read this whole User’s Manual before proceeding. During the ﬁrst hours of opera=on it is cri=cal to allow all components to properly wear in. This is accomplished by simply taking care to run the board through its full RPM range repeatedly to full power, avoiding prolonged full power opera=on more than a few minutes at a =me for the ﬁrst 2-3 charge cycles. Peak eﬃciency is typically achieved aber 5-6 cycles Page...
Page 16 Unpacking and checking your Kymera Inside your vehicle The Kymera is a fairly small watercrab, which means that it will ﬁt easily into most cars with the back seats down. Here are three in the back of a Range Rover Sport, two in the back of an Audi sedan and one in the back of a Mazda 2! Held verTcally on kayak J-bars or horizontally on kayak cradles ... or both In your boat, in the back of your pickup, trailer or there are plenty of other ways to carry your Kymera depending on your vehicle and other equipment available to you!   TransporTng on foot There are mul=ple ways to transport your Kymera from your vehicle to the water once you get to your des=na=on: Using the included shoulder carry strap – every Kymera comes with a carry strap. Secure one end  of the carry strap to the front D-ring and the other end to the rear D-ring on the same side of the board.   Using a RailBlaza C-TUG trolley - these are great for transpor=ng your board the long distance from  your car to the water. Find them on the Wavez Store: hFp://www.wavez.com.au/railblaza-c-tug-trolley  hFp://www.wavez.com.au/railblaza-c-tug-sandtrakz  Page...
Page 17 Unpacking and checking your Kymera Prepare Adult supervision is required! Never allow under-age riders to operate your Kymera! Ensure you have checked your board thoroughly, especially the electronics housing thumb screws and veriﬁed there is no water in the electronics housing, and read this whole User’s Manual before proceeding. Always comply with all local rules and regula=ons rela=ng to vessel registra=on, operator licensing, speed limits, exclusion zones and anything else which may apply Carry/wheel the board and baFery to the water’s edge and place on stands (if available) Never carry the board using the right handle, as you may bend and damage the trigger inadvertantly. Whenever possible use stands or other means to prevent the board from res=ng directly on the ground. This will reduce the chance of debris entering the pump and/or hull. Put anything you’d like to keep dry into the glove box. We recommend that you put the carry strap in there now. Ensure the baFery is CLEAN and install it. Once the baFery is fully seated and locked into place, verify the baFery is turned OFF (the lever is poin=ng forwards) and plug it in. The baFery should always be kept CLEAN. DO NOT put the baFery on the ground or on the sand. Debris transferred into the interior of the board, especially sand, can foul the motor or drive shab bearing requiring professional servicing. Verify that the throFle trigger is in the OFF posi=on (fully forward). Some=mes when you lean over the board you may inadvertently pull the trigger. Switch the baFery to the ON posi=on and the board will beep and the baFery meter will light up. Once the beeps stop, the board will take up to 10 more seconds to fully ac=vate. Do not pull the throFle trigger during this =me or you may need to repeat the startup procedure to get the board to operate properly. Never leave your board in the water unaFended Never leave your board anywhere unaFended with the baFery in the ON posi=on Launch Adult supervision is required! Never allow under-age riders to operate your Kymera! Always comply with all local rules and regula=ons rela=ng to vessel registra=on, operator licensing, speed limits, exclusion zones and anything else which may apply Always ensure you always wear an approved life vest appropriate for the condi=ons and fully secured before entering the water. Never operate your Kymera under the inﬂuence of drugs or alcohol (or allow others to do the same) Never operate your Kymera at unsafe distances from swimmers, surfers or other water users Never operate your Kymera in very bad weather or very rough condi=ons Never overload your board by exceeding the weight limit or carrying mul=ple passengers Verify both the front and rear hatches are secured and place the board in the water. Page...
Page 18 Unpacking and checking your Kymera Once in knee to waist deep water, press up and down on the tail of the board repeatedly, which will push water through the jet assembly, clearing any sand or debris that may have entered. Dunking is a cri=cal step to prevent scoring the inside of the pump housing, damaging the jet assembly and/or the impeller and reducing performance. Never allow any debris to enter the jet assembly! Once dunked, with both hatches secured, verify your lifejacket is secured and you are free to board from either side or the rear. Lie down on the board and posi=on yourself into the centre. The knee pockets at the rear will help with proper placement. The handles can be used to adjust your posi=on but be mindful of the throFle trigger located on the right handle is not inadvertently ac=vated. Straighten your arms to ensure your body weight is at the back of the board, or the nose will dive as soon as you begin to move away from shore. Once comfortable, check your surroundings for other water users before gently pull the throFle located on the right handle and the board will begin to move forward. Check the water outlets on both the right and led side of the board to verify cooling water ﬂow. A small stream of water on either side should be visible coming from small silver ﬁings on the board. Increase speed by squeezing harder on the throFle trigger. During the ﬁrst hours of opera=on it is cri=cal to allow all components to properly wear in. This is accomplished by simply taking care to run the board through its full RPM range repeatedly to full power, avoiding prolonged full power opera=on more than a few minutes at a =me for the ﬁrst 2-3 charge cycles. Peak eﬃciency is typically achieved aber 5-6 cycles. Ride Adult supervision is required! Never allow under-age riders to operate your Kymera! Be mindful of your surroundings including other water users, swimmers, boats, water depth, hazards and distance to shore. Kymera should never be operated further from shore than your physical ability to paddle or swim unless a support vessel or lifeguard is present. Always keep the shore visible. When travelling at 10 knots (18km/h) or more, keep 60 metres from any person in the water (including a surfer or boogie boarder), sailing vessel or passive crab When travelling at 10 knots (18km/h) or more, keep 30 metres from another power driven vessel, the shore, any moored/anchored vessel, or any structure or object Never surf big waves with your Kymera (32kg of Kymera tumbling through the waves is a bad idea for you, other water users and your expensive watercrab!) Start riding with your arms straight, then shib your body weight forward when you begin to plane. Steering the board is achieved with a combina=on of shibing the lower half of your body weight leb and right, foot placement (ac=ng as rudders) and hand placement (ac=ng as water brakes). At low speed, your weight should be shibed further towards the tail and will require more steering with feet or hands. Having your weight further back will also lib the nose in choppy water, prevent submersion and improve steering. As the board picks up speed, you should shib your weight forward propor=onate to speed. At full power, your best posi=on is typically with your chest all the way to or near the front hatch. This will assist with helping the board to plane, minimise the amount of hull below the water and maximise speed. Slow down or stop by releasing the throFle trigger. The board will stop planing, dropping into the water. The water resistance will make the board stop quickly.
Page 19 Unpacking and checking your Kymera When slowing down, do so progressively and shib your weight backwards, by straightening your arms, to avoid the nose diving and water coming over the bow. The less water in the board, the easier the cleaning aberwards. Keep in mind the board will react diﬀerently depending on how the riders weight is shibed both from side to side and front to back. Also shibing more weight on a knee will cause a diﬀerent eﬀect than just moving your body weight. Kymeras respond best when weight is shibed leb and right towards the rear of the board. Moving your upper body weight can destabilise the board and cause the nose to dive, but pushing your shoulders up and pushing your weight back when you turn can be highly eﬀec=ve. Riding quickly becomes intui=ve, and soon it will feel as though simply thinking to head in a speciﬁc direc=on will cause the desired reac=on. This symbio=c system provides a much more engaging experience as you hone your skills and develop your own style of riding.  Want to turn right using your hand as a water brake? Reach across the board with your leb hand to take hold of the throFle and then your right hand is free to use. This also shibs your body weight to the right side, further improving your turn. When riding always use the 2/3rd’s rule: never using more than 1/3rd baFery on the way out, leaving 2/3rd’s for the ride back. Changing wind and current condi=ons can require more baFery on the way back. Pay par=cular aFen=on to changing condi=ons and turn back immediately if condi=ons begin to deteriorate. Your Kymera’s baFery meter (located inside the ebox under the front hatch) displays the baFery % remaining. The Kymera will typically switch to reserve at around 20% remaining.  Take care when accessing the front hatch to prevent water entry When the baFery is depleted, emergency reserve power will ac=vate dropping the Kymera to a speed of 8-10kph for 5-10 minutes.  Reserve mode should be used only in emergency situa=ons and not counted in your 2/3 ’s riding plan. You should aim to be back to shore just as your baFery enters reserve mode. Carry a reliable means of communica=on to shore with you at all =mes for use in case of emergency Pay aFen=on to the amount of water in the board. Par=cularly when ridden by a beginner, or in choppy water, the board may take on a bit of water. Check from =me to =me and ensure that you do not ride the board for extended periods of =me with a lot of water in the board. Although everything in the board interior is water resistant, the components are not intended to be operated when submerged, and it can increase the likelihood that components like the motor or drive shab bearing require professional servicing earlier than they otherwise would. If it builds up, return to shore, remove the baFery and drain water from the board. Emergency Turning and Stopping Some=mes, you need to turn or stop FAST! This could be due to you seeing some debris in the water you’d rather not hit, or a swimmer emerging from the water in the middle of a watercrab area! Sharp Turn You can execute a sharp turn by throwing your weight to the leb side of the board and dropping your leb arm in the water at 90 degrees to the direc=on of travel, and even dropping your leb foot into the water too. The more weight you shib to the leb, the sharper the turn. This move will turn the board aggressively to help you keep away from any obstacles, and cut your speed drama=cally. Turn and Stop If you want to turn and stop, execute the same move but take your ﬁnger oﬀ the throFle. The turn won’t be as aggressive, the board nose will dive and you may even fall oﬀ, but you’ll stop! For more eﬀect, hold onto the leb handle, push back on the right handle and push yourself oﬀ the board. Neither you nor your board are going anywhere! Two-handed Stop If you want to stay on your board but stop quickly, another great move is to use BOTH hands as water brakes, dropping them both into the water at the same =me, to the leb and right, at 90 degrees to the direc=on of travel. Dropping one or both feet or legs into the water can...
Page 20 Unpacking and checking your Kymera Return to shore and remove the ba[ery At the end of your ride proceed slowly back to shore watching out for obstruc=ons. Once at the shore, maneuver the board back onto land. Once siUng securely on land (ideally ‘oﬀ’ land on stands) open the front hatch and power oﬀ the baFery. Allow a few seconds aber switching oﬀ the baFery for the ebox’s LEDs to turn oﬀ. Remove the power plug and lower the locking bar. Once free, lib the front of the baFery while sliding forward, reversing the installa=on process. Return the baFery to the hard carry case. Once the baFery is removed from the board, any water in the hull can be drained by standing the board up on its tail. This can also be achieved by placing the stands on a slight incline, but standing the board on its tail is most eﬀec=ve. It’s normal to have a bit of water in the board aber a run, especially in choppy water or if the nose of the board has become submerged. Flex in the board, combined with a large rectangular hatch, can allow some water to enter. This is normal, don’t worry! It shouldn’t aﬀect the handling of the board and will drain away quickly. However, if the water doesn’t drain away, do not con=nue to operate the board with internal components submerged under water. The board is now ready to be transported. You can double your run=me (and double your fun!) by taking a spare baFery to the water with you. For long trips, for example a camping holiday, you should also consider buying a high quality electric generator to allow you to recharge your Kymera baFeries mul=ple =mes. Ensure that the generator provides high quality elecricity suitable for serving electrical equipment like laptops or, of course, lithium baFery chargers. The generator must provide a con=nuous output of a minimum of 2kVA. Never leave your board in the water unaFended Never leave your board in the water when not in use Daily Maintenance Cleaning up the board aber use, at least once at the end of the day, is absolutely CRITICAL to ensuring that the board remains in good working order. Failure to clean the board, resul=ng in component damage or degrada=on, is NOT covered by warranty. 1. Wipe down and recharge your ba[ery If you haven’t done so already, remove the baFery and wipe it down with a towel or chamois.  Do not hose the ba[ery down! Although the baFery is water resistant, water under high pressure hosed onto the baFery could enter the baFery case. Check the terminals for any sand or water and blow or use a squeeze bulb to blow anything out of the terminals. Fully recharge the baFery before storing. 2. VERY IMPORTANT! Flush your cooling lines h[ps://youtu.be/CC88yfKew-w Your cooling lines MUST be ﬂushed aber use in dirty or salty water, to ensure that any debris or salt water remaining in the cooling block does not dry out, harden and block the cooling lines or the cooling block inside the electronics housing. Lie the board LEVEL on the ground, kayak stands or workhorses for ﬂushing to ensure that water can ﬂow easily through the cooling lines.  AFach the provided ﬂush adapter to the standard hose ﬁUng, turn the hose on with low water pressure and hold it up to the water outlets on the leb and right-hand sides of the board (just behind where your elbows would have been posi=oned) to clear out any salt water which remains in the cooling lines. As a rule of thumb, low pressure is measured by holding the hose with ﬂush adapter poin=ng upwards, and observing a stream of water extending roughly 10in into the air.
Page 21 Unpacking and checking your Kymera Make sure you use the ﬂush adapter to ensure that suﬃcient water is ﬂowing through the system. You should be able to see bubbles moving through the cooling lines via the rear hatch, indica=ng that water is ﬂowing. If in doubt, take the ﬂush adapter oﬀ the side to allow air bubbles into the line, and then repeat. Water will exit the board via the jet nozzle at the rear. Allow the water to ﬂow through the lines for at least 30 seconds each side to ensure that any residual salt is cleared.   High pressure in the cooling lines due to blockage can result in the cooling lines burs=ng and water ﬂooding the electronics housing or the board. Running a board with a ﬂooded electronics housing will cause permanent damage which is not covered under warranty. This is REALLY IMPORTANT! I know I’m repeaTng myself, but if your cooling lines are not cleared ader use, especially in salt water, a blockage will likely occur. If that blockage is inside the ebox’s cooling block, conTnuing to run the board may cause permanent damage! If your cooling lines are blocked, and no water is coming out of the outlets on both sides behind your elbows, you must NOT operate the board! The pressure build-up caused by the jet pushing water through the cooling system can cause failure of the cooling system inside the electronics housing, ﬂooding it with water and damaging your board. Here is a video showing the cleaning and ﬂushing procedure – please watch it all the way through! Note the low water pressure used to ﬂush the cooling lines – all you want to do is gently push fresh water through the lines to replace any salt water. hFps://www.youtube.com/watch?v=CC88yfKew-w Damage caused by failure to properly maintain your board will NOT be covered under warranty. 3. Hose down your board inside and out If you have not already done so, remove the ba[ery and wipe down with a cloth before cleaning the board Lie the board LEVEL on the ground, kayak stands or workhorses for cleaning to ensure you can easily access all board surfaces. Hose the board down inside and out using a hose on shower seUng. Everything inside the board is waterproof, and hosing everything, especially salt water, oﬀ all internal components aber use will keep your board in great condi=on.  Do not clean your whole board with a high pressure washer! This can result in water ingress into the electronics housing, the digital thro[le, the waterproof glove box or another part of the board which is waterproof but not high-pressure hose proof. If you have used the board in salt water, especially if any water has built up inside the board and got into the motor or the drive shab bearing, it is par=cularly important to hose the motor and the drive shab really thoroughly with the hose on high/jet seUng. Salt and sand can make its way into these components and seize them up if they are not cleaned thoroughly aber use. We recommend spending 30 seconds hosing the board through the front hatch (focussing especially on the motor), 30 seconds through the rear hatch (focussing especially on the motor and bearing), 30 seconds on the top of the board especially the trigger and other metallic components and 30 seconds on the underside of the board, especially focussing on the impeller and jet assembly. Here is a video showing the cleaning and ﬂushing procedure – please watch it all the way through! Note the low water pressure used to ﬂush the cooling lines. All you want to do is gently push fresh water through the lines to push out any salt water and replace with fresh. h[ps://www.youtube.com/watch?v=CC88yfKew-w Storage One of the great things about a Kymera is how easy it is to store. Pick a place to store your board either lying ﬂat or standing on its tail (where it won’t fall over).  Ensure your board has been fully cleaned and ﬂushed and the baFery is on charge, as above. Ensure your board is clear of water: Let most of the water drain out by leaving the board to stand on its tail for a few minutes (op=onal) Lay the board ﬂat on the ground. Any remaining water will run forward to the lowest point under the baFery tray and electronics...
Page 22 Unpacking and checking your Kymera Store your board with the rear hatch open to ensure that any remaining moisture has an opportunity to escape Store your board anywhere you like either laying down on shelves or standing on its tail in the corner of your garage or even your spare room! If you are concerned about residual water draining from the board you may like to sit it on a towel or with the chamois under the drain plug. Extended Storage It is important to dry out the board before storage for any extended periods of =me to ensure your board doesn’t become mouldy or aFract mosquitos Aber draining water from the board, stand the board on its tail or lay it with the nose higher than the tail to get most of the water to exit the board via the self-draining plug at the rear of the board. When the plug stops expelling water, lay the board ﬂat on the ground, a kayak stool or work horse. Water will pool near the front of the board and use a chamois to remove any remaining water. Leave both hatches open aber use and cleaning to allow the board to dry fully. Any residual salt water, or if the board is stored in a salty environment, creates the risk of rust and corrosion on all metalwork, as with all vessels, vehicles and motors. It is cri=cal to protect the board with corrosion inhibiters before storing for an extended period where the board won’t be used and cleaned regularly. Once the board is fully dry, apply one small squirt of grease into both grease nipples (don’t apply too much grease). Then, apply Inox or a similar corrosion inhibiter to all of the metalwork in the board, including but not limited to: the whole drive shab the drive shab bearings the motor, front and back all stainless screws and ﬁxtures Servicing Properly cleaning and maintaining your Kymera is criTcally important to ensure longevity of the board. PrevenTon Do not ride your Kymera in shallow water, water with large amounts of debris (for example, aber heavy rain) or in water with high levels of par=culate (for example sand or dirt). Aber each use, remove the baFery and drain the board of water completely. Avoid submerging electronics by =pping the board nose up allowing water to drain out the rear. At the end of your day out, hose your Kymera with clean fresh water inside and out. Avoid submerging electronics by =pping the board nose up allowing water to drain out the rear. At the end of your day out, clean the cooling lines with clean fresh water using a hose and the supplied cooling line adapter on LOW pressure (see above). With the baFery unplugged and removed, ensure that the jet pump and impeller are clean and clear of obstruc=ons. Carefully remove foreign material, if any. Page...
Page 23: Troubleshoo=Ng
Unpacking and checking your Kymera Proper lubrica=on is cri=cal to performance and should be repeated when in regular use and before storage. When opera=ng in saltwater, weekly or more is advised to clear any trapped moisture. There are two grease ﬁUngs: (1) inside the rear hatch and (1) inside the pump (see below) Greasing the drive shad Grease the drive shab regularly, especially when your Kymera is used in salt water. Your coupler and drive shab (under the rear hatch) should turn easily by hand. If there is any resistance, you have not applied suﬃcient grease. If it won’t move at all, see ”Troubleshoo=ng” p24.  If you’re going to do a thorough clean of the board, complete that before greasing the board, as cleaning products may take grease with it. Tools required To complete this work, you will need a grease gun with ﬂexible hose, long shab quick release coupler and marine grease. This is all available in the Kymera Maintenance Kit. Step 1: greasing the drive shad via the rear of the pump Put the board on a table so you can easily get at the jet nozzle The ﬁrst =me, aFach the ﬂexible hose and long shab quick release coupler to the grease gun, and insert the grease cartridge Remove any air from the grease barrel by gently squeezing the trigger un=l a small amount of grease is seen at the =p of the coupler Push the coupler in through the middle of the jet nozzle up against the grease nipple in the pump Pull the trigger on the quick release coupler so that it grabs the grease nipple Apply one squirt of grease only Pull the trigger on the quick release coupler to allow removal from the grease nipple Do not forcefully remove the coupler, as damage may result. Step 2: greasing the drive shad via the rear hatch With the board s=ll on the table, ensure you can easily reach inside the rear hatch Open the rear hatch Feed the connector through the rear hatch towards the tail of the board, above the chassis (you should see the grease nipple there) Pull the trigger on the quick release coupler so that it grabs the grease nipple Apply one squirt of grease only Pull the trigger on the quick release coupler to allow removal from the grease nipple Close the rear hatch – you’re done! Cleaning out the board Do not EVER use a high pressure hose to clean the inside of the board. Water ingress into the electronics housing will void your warranty and cause permanent damage. From =me to =me, the board may require cleaning out. It may take on sand or silt or other small debris. The best way to clean it out is to remove the drain plug using a shiber or ring spanner. This will leave a hole around 2cm in diameter at the tail of the board. You can then stand the board on its tail and thoroughly hose out the board. Debris should be able to escape through this hole. You may need to =lt the board over, as debris may seFle on the other side of the board rather than escape through the hole. Remember to re-install the drain plug aber Page...
Page 24 Unpacking and checking your Kymera you’re ﬁnished, or the next ride will be a short one!  When re-installing the drain plug, do so carefully and don’t over =ghten it, or you may strip the thread. If you have used the board in salt water and are concerned that there may be some salt build up inside the board, you may wish to purchase a product like “salt-away” to dissolve the salt. Do not use a home remedy like vinegar or detergent to clean the board or dissolve salt. They may cause damage to components of the board. Ensure you grease the board aber a really thorough clean, as the cleaning process may take some of the grease with it. TroubleshooTng If for any reason you believe your baFery may have become damaged, DO NOT OPEN OR MODIFY IT IN ANY WAY! Opening the baFery is unsafe and will void your warranty. Discon=nue use immediately, move it to a safe loca=on away from people, pets and property and contact Kymera at support@kymerabodyboard.com If for any reason moisture or water is seen in the electronics housing, DO NOT OPEN OR MODIFY IT IN ANY WAY! Opening the electronics housing is unsafe and will void your warranty. Discon=nue use immediately and contact Kymera at support@kymerabodyboard.com If at any =me while riding there is a loss of power, remain calm and move from the prone to seated posi=on on the board to improve your visibility on the water. Look around you to ensure that you are in a safe place. If not, paddle to a safe place. Once safe and seated, open the front hatch of the board and check the posi=on of the baFery power switch. This switch also serves as the system breaker. Should the system become over taxed, this switch will automa=cally ﬂip to oﬀ to protect the system. Reset the breaker by opening and re closing. In some cases it may require a few minutes before it will reset. Once reset you will again hear the ac=va=on beeps and the board should be ready to use. Proceed with cau=on and SLOWLY return to a safe loca=on on shore. Once there, power down the system, remove the baFery and verify the pump is clear of obstruc=on. Once conﬁrmed clear, with the baFery s=ll removed, remove the rear hatch and manually turn the motor / shab to ensure it turns freely. Take care when accessing the front hatch to prevent water entry Always remove the baFery prior to opening the rear hatch If at any =me during opera=on there is a noise or reduc=on of power that seems out of place, reduce power and return to the nearest safe shore loca=on. When in doubt power the board oﬀ and wait 10 seconds, power it back on and proceed slowly to shore if possible un=l the problem has been diagnosed.  In all cases, ensure that the problem is diagnosed and resolved before conTnuing to use your Kymera. Kymeras are high-performance watercrad and place high demands on all components. MalfuncToning components can result in permanent and expensive damage to the board if it is conTnued to be operated!

Page 28 Unpacking and checking your Kymera Allen Keys Most parts on the Kymera are secured with Allen keys and bolts. The Kymera uses bolts which are best removed with a combina=on of imperial and metric allen keys. It is worthwhile having a set of both on hand to allow =ghtening of loose bolts or removal of jet pump components to remove debris or replace parts.  We recommend ball-socket T-bar Allen keys, especially for the imperial set. You’ll need an ¼” long handle allen key (T-bar is best) to remove and/or replace jet pump assembly components. If you’ve used your board in salt water, before you remove any bolts you should ensure that you thoroughly wash AND SOAK your board in fresh water – even run it in a fresh water lake or river if you have the chance. Otherwise the salt inside the connectors may lock them in place, preven=ng removal and even damaging the board. This is especially important for the ¼” bolts securing the jet pump assembly to the hull. Roof rack We like Rhino Racks, but what roof rack you choose (if you would rather not carry your Kymera inside your car) is up to you.  Check out the op=ons available to you at your local roof rack dealer. If you intend to carry two Kymeras on the roof of your car, we recommend 1.8m wide roof rack bars, but you need a minimum width of 1.3m to allow the rear of the boards to sit ﬂat on the crossbar side by side. We’ve tried kayak cradles and J-bars, but in the end we found that the easiest way to transport Kymeras is ﬂat on the roof bars. Lockable roof rack Te down straps We love KanuLocks! A pair of orange 3.3m long straps are plenty to secure a Kymera safely onto a roof rack. They won’t stop a determined thief, but they’ll stop opportunists, giving you peace of mind.  You can ﬁnd them on eBay.
