General Safety

When using electric yard tools, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury, including the following:

1. Keep guards in place – Protective guards should be checked periodically to ensure they are properly fitted and in correct working order.
2. Remove adjusting keys and wrenches – Check that adjusting wrenches are removed from the saw before turning it on.
3. Keep work area clean and well-lit – Clear work area of branches and limbs after each cutting session. Cluttered areas invite accidents.
4. Do not use in dangerous environments – Do not use power tools in damp or wet locations.
5. Do not use the 2-in-1 pole + chain saw in the rain.
6. Keep bystanders and children away – All bystanders, including children and pets, should be kept a safe distance away from the work area.
7. Do not force the tool – It will do the job effectively and safely if it is used at the rate for which it was designed.
8. Use the right tool – Do not force the tool or any attachment on the tool to do a job for which they were not designed.
9. Wear proper apparel – Do not wear loose articles of clothing or jewelry since such items may get caught in moving parts. Use of heavy-duty rubber gloves, substantial non-skid footwear, and close-fitting clothing is recommended when working outdoors with power tools.
10. Wear protective hair coverings to contain long hair.
11. Always wear safety glasses and ear defenders to provide eye and ear protection – Everyday eyeglasses only have impact resistant lenses and do not provide the same protection as safety glasses.
12. Wear face or dust masks – If the cutting operation is dusty, the use of a face or dust mask specially designed to filter out microscopic particles is recommended.
13. Do not overreach – Keep proper footing and balance at all times.
14. Maintain tools with care – Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.
15. Disconnect tool – Disconnect the 2-in-1 pole + chain saw from the power supply when not in use, before servicing, when transporting, or when changing the chain or other accessories.
16. Reduce the risk of unintentional starting – Make sure the switch is in the OFF position before plugging the tool into a power source.
17. Use recommended accessories – Consult the owner's manual for recommended accessories. The use of improper accessories may cause risk of injury.
18. Check for damaged parts – Before each use, repair, or replace any guard or part that is damaged. In addition, check for alignment of moving parts, binding of moving parts, breakage of parts, and any other conditions that may affect the tool's operation.
19. Never leave tool unattended while it is running – Turn the power OFF by removing the power cord directly from its socket. Do not leave the saw until the cutting bar comes to a complete stop.
20. Avoid unintentional starting – Do not carry the 2-in-1 pole + chain saw with your finger on the switch.
21. Do not grasp the exposed cutting blade or cutting edges when picking up or holding the saw – Be sure to encase the cutting bar in its protective sheath when not in use.
22. Stay alert – Watch what you are doing. Use common sense. Do not operate the 2-in-1 pole + chain saw when you are tired.
23. Store idle tool indoors – When not in use, appliances should be stored indoors in a dry and high or locked-up place out of the reach of children.

Electrical Safety

1. Ground fault circuit interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the 2-in-1 pole + chain saw. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.
2. To prevent electric shock, use only with an extension cord suitable for outdoor use, such as SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A, or SJTOW-A. Before use, check that the extension cord is in good condition. When using an extension cord, make sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
3. To reduce the risk of electric shock, this appliance has a polarized plug (i.e. one blade is wider than the other). Use this appliance only with a polarized UL-, CSA-, or ETL-rated extension cord for outdoor, all-weather use. The appliance plug will fit into a polarized extension cord only one way.

If the appliance plug does not fit fully into the extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A polarized extension cord will require the use of a polarized wall outlet. The extension cord plug will fit into the polarized wall outlet only one way. If the plug does not fit fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified electrician to install the proper wall outlet. Do not modify the appliance plug, extension cord receptacle, or extension cord plug in any way.

Electric shock may cause SEVERE INJURY or DEATH. Heed these warnings: Do not allow any part of the 2-in-1 pole + chain saw to make contact with water while it is in operation. If the appliance becomes wet while turned off, wipe dry before starting. Use only a UL-, CSA-, or ETL-rated extension cord for outdoor, all-weather use. Do not use an extension cord over 100 ft (30 m). Do not touch the appliance or its plug with wet hands or while standing in water. Wearing rubber boots offers some protection. EXTENSION CORD CHART
Cord Length:	Up to 50 ft (15 m)	+50 ft - 100 ft (+15 m - 30 m)
Min. Wire Gauge (A.W.G.):	16	14

4. To prevent the appliance cord from disconnecting from the extension cord during operation, make a knot with the two cords as shown in Table 1.
   
5. Do not abuse the cord. Never pull the 2-in-1 pole + chain saw by the cord or yank the cord to disconnect it from the receptacle. Keep the cord away from heat, oil, and sharp edges.

Specific Safety Rules

SHOCK HAZARD! – To protect yourself from electrocution, do not operate the 2-in-1 pole + chain saw within 50 ft (15 m) of overhead wires. Failure to follow this instruction could result in severe personal injury.

Operating Tips for Pole Chain Saws

• Note the extension cord's location relative to the tool. While operating the pole chain saw, be careful not to trip over the cord.
• Keep the cord away from the chain and the operator at all times.
• Keep children, animals, and bystanders a safe distance away from the pole chain saw and extension cord.
• Only the pole chain saw operator should be in the work area.
• Do not use the pole chain saw to cut down trees.
• Always use two hands when operating the pole chain saw. Grip the pole chain saw securely with one hand on the trigger and the other hand on the pole.
• Before starting the pole chain saw, make sure that the saw chain is not in contact with any object.
• Do not allow the pole chain saw to make contact with grounded objects such as pipes, fences, and metal posts.
• Do not force the pole chain saw while cutting. Apply light pressure. It will perform more effectively and safely if it is used at the rate for which it was designed.
• Use extreme caution when cutting a limb that is under tension. When wood tension is released, the limb could spring back and strike the operator, causing severe injury or death.
• Do not carry a plugged-in unit. Carry the pole chain saw from one place to another with the unit unplugged. During transport, hold the pole at its balance point (close to the saw end), with the guide bar and chain facing to the rear. When transporting or storing the pole chain saw, always fit the guide bar cover.
• Do not cut small brush and saplings with the pole chain saw. Small branches may catch in the chain and be whipped towards the operator, which could pull the operator off balance.

Operating Tips for Chain Saws

• Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating the chain saw may cause entanglement of your clothing or body with the saw chain.
• Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
• Wear safety glasses and hearing protection. If you are using the chain saw every day under normal conditions, you can be exposed to a noise level of 85 dB (A) or higher. Further protective equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
• Do not operate the chain saw in a tree. Operation of a chain saw while up in a tree may result in personal injury.
• Always keep proper footing and operate the chain saw only when standing on a fixed, secure and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.
• When cutting a limb that is under tension, be cautious of spring back. When the tension in the wood fibers is released, the spring-loaded limb may strike the operator and/or throw the chain saw out of control.
• Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
• Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw, always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning and changing accessories. An improperly tensioned or poorly lubricated chain may either break or increase the chance for kickback.
• Keep handles dry, clean and free from oil and grease. Greasy, oily handles are slippery and can cause loss of control.
• Cut wood only. Do not use the chain saw for any other purpose. For example, do not use the chain saw to cut plastic, masonry or non-wood building materials. Using the chain saw in these incorrect ways could result in serious damage to you and your tool.

Kickback

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.

AVOID CONTACTING THE GUIDE BAR TIP WITH ANY OBJECT. In some cases, when the tip makes contact with an object, it may cause a fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may also push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious personal injury.

• When using as a pole chain saw, always use two hands when operating the pole chain saw, one hand gripping the trigger and the other hand gripping the pole. Use a firm grip. Thumbs and fingers must wrap around the trigger and the pole. When using as a chain saw, maintain a firm grip (right hand on the rear handle and left hand on the front handle with thumbs and fingers encircling the respective handles) and position your body and arms to allow you to resist kickback forces. Kickback forces can be controlled by the operator if proper precautions are taken. Do not let go of the chain saw.
• Keep all guards in place on the machine. Make sure they are in proper working order.
• Do not overreach. Do not extend arms above shoulder height when using as a pole chain saw or cut above shoulder height when using as a chain saw. This helps prevent unintended tip contact and enables better control of the unit in unexpected situations.
• Keep solid footing and balance at all times.
• Never try cutting through two branches at the same time. Only cut one at a time.
• Do not bury the guide bar nose or try to cut by boring the guide bar nose into the wood.
• Watch for shifting of wood or other forces that may pinch the chain.
• Use extreme caution when re-entering a previous cut.
• Use the low-kickback chain and guide bar supplied with this 2-in-1 pole + chain saw. Only use genuine Snow Joe^® + Sun Joe^® replacement parts designed specifically for use with this 2-in-1 pole + chain saw.
• Never use a dull or loose chain. Keep the chain sharp and properly tensioned.
• Follow the manufacturer's sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.
• Always observe the safety regulations and follow the correct sawing techniques.
• Ensure safe carrying of the unit. Whenever the machine is to be handled or transported, you must:
  • Switch off the motor and wait for the chain to come to a complete stop;
  • Mount the guide bar cover;
  • Hold the machine using the hand grips and position the bar in the opposite direction to that used during operation. When using a vehicle to transport the machine, fasten the tool firmly and position it so that it is not a danger to any passengers.
• Before cutting, pruning, or delimbing for the first time, make sure:
  • You have been specifically trained to use this type of equipment;
  • You have carefully read the safety regulations and user instructions contained in this manual;
  • You practice first on logs on the ground or attached to trestles/saw horses, in order to get familiar with the machine and the proper cutting techniques.

Always make sure that the handle lock is locked securely before using the chain saw.

Operation

Starting and Stopping

• Starting, stopping, and restarting an electric motor repeatedly within a few seconds can generate a great deal of heat and damage the motor. To protect the life of your 2-in-1 electric pole + chain saw, always wait at least five seconds after stopping before restarting the saw.

Be sure that the chain is not in contact with any object when you start the motor.

Keep hands away from chain. Keep hands on handles. Do not overreach.

A good, firm grip on the tool using both hands will help you maintain control. When using as a pole chain saw, place one hand on the soft grip and the other hand on the removable handle with your thumbs and fingers encircling the pole and handle. When using as a chain saw, maintain a firm grip by placing your right hand on the rear handle and left hand on the front handle with thumbs and fingers encircling the respective handles. A firm grip combined with proper positioning of the handle against your body will help you maintain control of the saw. Do not let go of the saw while it is in operation.

Do not operate the 2-in-1 pole + chain saw in a tree, on a ladder, or on a scaffold. Using the tool under such circumstances is extremely dangerous.

The chain will continue to run for several seconds after turning off the tool.

Do not use the 2-in-1 pole + chain saw under wet conditions. Use extreme caution when cutting small brush, saplings, or limbs under tension because slender and tense material may catch the saw and be whipped toward you, pull you off balance, or spring back.

Do not use the 2-in-1 pole + chain saw to cut vines and/or small underbrush.

Do not let familiarity with this type of tool prevent you from taking all necessary precautions. Remember that a careless fraction of a second is sufficient to inflict serious injury.

Do not cut trees near electrical wires.

Failure to lubricate the chain will cause damage to the bar and chain. Use only a good quality bar and chain oil designed specifically for use with chain saws.

One minute of use will consume approximately 0.15 fl oz. (4 ml) of oil.

NOTE: It is normal for oil to seep from the saw when not in use. To prevent seepage, empty the oil tank after each use. When storing the unit for a long period of time (3 months or longer), be sure the chain is lightly lubricated; this will prevent rust on the chain and bar sprocket.

Be aware of the cord while operating the saw. Keep the cord away from the chain. Be careful not to trip over the extension cord.

1. Prior to each cutting session, run through the daily checklist.
2. Connect the 2-in-1 electric pole + chain saw to a working 120 V outlet using a heavy-duty outdoor extension power cord.
3. Push the appliance cord through the first two slots of the extension cord restraint hook, push the extension cord through the remain two slots of the extension cord restraint hook (Fig. 18). Then connect the cords.
   
4. To turn the tool ON, push and hold the safety lock button (located on the removable handle) with your thumb and then squeeze the trigger with your fingers. Once the tool is running, you can release the safety lock button (Fig. 19).
   
5. To turn the tool OFF, release the trigger switch (Fig. 16).

NOTE: Do not press the trigger switch until you are ready to make a cut.

Adjusting the Telescoping Pole (Optional)

When being used as the pole chain saw, the machine is equipped with a telescoping pole which provides up to 15 ft (4.6 m) of overhead reach. To adjust the telescoping pole, follow the instructions below.

1. Disconnect the saw from the power supply.
2. Unclip the cam-lock to release the pole (Fig. 20).
   

Cutting Tips for Pole Chain Saw

Proper Cutting Stance

• Balance your weight with both feet on solid ground.
• Your body should always be to the left of the chain line.
• The most typical cutting application is to position the unit at an angle of 60° or less depending on the specific situation (Fig. 24). As the angle of the pole chain saw shaft to the ground increases, the difficulty of making the first cut (from the underside of limb) increases.
  

Basic Cutting Procedure

This unit is designed for trimming small branches and limbs up to recommended 8.5 in. (21.6 cm), not to exceed a max cut of 9.5 in. (24.1 cm) in diameter depending on type of wood. Practice cutting a few small limbs using the following technique to get the "feel" of using the saw before you begin a major sawing operation.

• Take the proper stance in front of the tree with the saw OFF (Fig. 24).
• Squeeze the trigger and let the chain accelerate to full speed before entering the cut.
• Keep the saw running the entire time you are cutting; maintain a steady speed.
• Allow the chain to cut for you; exert only light downward pressure. If you force the cut, damage to the bar, chain, or unit can result.
• PUSH and PULL – This reaction force is always opposite to the direction the chain is moving when it is in contact with the wood. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and PUSH when cutting along the top edge.
• Do not put pressure on the saw at the end of the cut.

Pruning

Pruning is the process of trimming limbs from a live tree.

• Remove long branches in several stages.
• Cut lower branches first to allow the top branches more room to fall.
• When pruning trees, it is important not to make the finishing cut next to the main limb or trunk until you have cut off the farthest lying limb. This will reduce the weight and prevent stripping the bark from the main member.
• Under cut the branch 1/3 through for your first cut. Your second cut should over cut to drop the branch off (Fig. 25). Be prepared to balance the weight of the pole chain saw when the limb falls.
  
• Now make your finishing cut from the topside of the branch smoothly and neatly against the main member so the bark will grow back to seal the wound.
• Release the trigger ON/OFF switch as soon as the cut is completed. Failure to follow proper cutting procedures will result in the bar and chain binding and becoming pinched or trapped in the limb.

Limbing

Limbing is the process of removing branches from a fallen tree.

• You should cut limbs one at a time. Remove the cut limbs from the work area often to help keep the work area clean and safe.
• Cut branches under tension from the bottom up to avoid binding the pole chain saw.
• Keep the tree between you and the pole chain saw while limbing. Cut from the side of the tree opposite the branch you are cutting.

If the Saw Becomes Pinched or Trapped

1. Wait for the blade to stop, wait five minutes for the saw to cool, unplug the power cord, and wear gloves to protect your hands from the chain teeth.
2. If you can reach the limb from the ground, lift the limb while holding the saw. This should release the "pinch" and free the saw.
3. If the saw is still trapped, call a professional for assistance.

Cutting Tips for Chain Saw

Proper Cutting Stance

• Weight should be balanced with both feet on solid ground.
• Keep your left arm and elbow locked in a "straight arm" position to withstand any kickback force (Fig. 26).
  

Basic Cutting Procedures

Do not cut limbs or trees that are larger than the maximum cutting thickness.

• Practice cutting a few small logs using the following techniques to get the feel of using the saw before you begin a major sawing operation.
• Take the proper stance in front of the wood with the saw turned off (Fig. 15).
• Squeeze the trigger and let the chain accelerate to full speed before entering the cut.
• Hold the saw with both hands firmly. Always keep your left hand on the front handle and your right hand on the rear handle so that your body is to the left of the chain line.
• Keep the unit running the entire time you are cutting, maintaining a steady speed.
• Let the chain do the work; exert only light downward pressure. If you force the cut, damage to the bar, chain, or unit can result.
• Do not put the pressure on the saw at the end of the cut.
• Always cut with both feet on solid ground to prevent falling.
• Do not cut above chest height since it is difficult to control kickback forces with a saw held high.

Felling a tree

• When bucking and felling are performed by two or more people at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled. Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If the tree does make contact with any utility line, the company should be notified immediately.
• The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.
• An escape path should be planned and cleared as necessary before cuts are started. The escape path should extend back and diagonally to the rear of the expected line of fall as illustrated (Fig. 27).
  
• Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to help you judge which way the tree will fall.
• Remove dirt, stones, loose bark, nails, staples and wire from the tree.

Notching undercut

Make the notch 1/3 the diameter of the tree, perpendicular to the direction of falls as illustrated (Fig. 28).

Make the lower horizontal notching cut first.

This will help to avoid pinching either the saw chain or the guide bar when the second notch is made.

Felling backcut

• Make the felling back cut at least 2 in. (50 mm) higher than the horizontal notching cut as illustrated (Fig. 28). Keep the felling back cut parallel to the horizontal notching cut. Strategically position the felling back cut so that enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge.
• As the felling gets close to the hinge, the tree should begin to fall. If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic or aluminium to open the cut and drop the tree along the desired line of fall.
• When the tree begins to fall, remove the chain saw from the cut, stop the motor, put the chain saw down, then use the retreat path planned. Be alert for overhead limbs falling and watch your footing.

Limbing

Limbing is the process in which branches are removed from a fallen tree. When limbing, leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut as illustrated (Fig. 29). Branches under tension should be cut from the bottom up to avoid binding the chain saw.

Pay special attention to where the branches are lying on the ground and recognize the following risks:

1. the branches may be under tension;
2. the direction in which the branch will fall may differ from that anticipated;
3. the tree may be unstable after the branch has been cut.

Bucking a Log

Do not buck logs that are larger than the maximum cutting thickness.

Bucking is the process in which a log is cut into lengths. It is important to make sure your footing is firm and your weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs, or chocks. Follow these simple directions for easy cutting:

• When the log is supported along its entire length as illustrated (Fig. 30A), cut from the top (overbuck).
  
• When the log is supported on one end (Fig. 30B), cut 1/3 the diameter from the underside (underbuck). Then make the finishing cut by overbucking to meet the first cut.
  
• When the log is supported on both ends (Fig. 30C), cut 1/3 the diameter from the top (overbuck). Then make the finishing cut by underbucking the lower 2/3 to meet the first cut.
• It is easier to saw a log using the spiked bumper (Fig. 30D).
• Dig the spiked bumper into the log and use it as a pivot. Cut with an arched motion to make the bar penetrate the wood.
• Repeat several times if necessary, changing the point where you plant the spiked bumper.
  
• When bucking on a slope, always stand on the uphill side of the log. When cutting through the log, maintain control by releasing the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Do not let the chain contact the ground.

After completing the cut, wait for the saw chain to stop before you move the chain saw. Always stop the motor before moving from tree to tree.

Damaged parts are to be replaced and never repaired.

• Only use original Snow Joe^® + Sun Joe^® replacement parts. Parts that are not of the same quality can seriously damage the equipment, compromise safety, and invalidate the warranty.
  Always unplug the power cord before performing any adjustments, maintenance, or repairs to your 2-in-1 pole + chain saw.
• Use protective gloves when handling the bar and chain.
• Keep the bar encased in its sheath, except when working directly on the bar or the chain.
• Never dispose of oils or other polluting materials in unauthorized places.

Motor Cooling

To avoid overheating and damage to the motor, always keep the cooling air vents clean and free of sawdust and debris.

Chain Tension

Check the chain tension before using the saw when the chain is cold. The correct tension of a cold chain is when there is no slack on the underside of the guide bar; the chain is snug, but you can rotate it by hand without binding.

During normal saw operation, the temperature of the chain will increase. The drive links of a correctly tensioned warm chain will hang approximately 0.050 in. (1.25 mm) out of the bar groove (Fig. 31). Be aware that a chain tensioned while warm, may be too tight upon cooling. Check the "cold tension" before next use. The chain must be re-tensioned whenever the flats on the drive links hang out of the bar groove (Fig. 31).

NOTE: A new chain tends to stretch. Check the chain tension frequently and re-tension as needed.

Nuts and Screws

Periodically check that all the nuts and screws are tightened securely. Check that the cam-lock that controls the telescoping pole is intact and in proper working order.

Chain Sharpening

To ensure that the saw works safely and efficiently, it is essential that the cutting components are well-sharpened. It is highly recommended to replace the chain once it loses its ability to cut cleanly and safely. It is possible, however, to sharpen the existing chain if the sharpening is carefully performed. Any work on the chain and bar requires specific experience and special tools. For safety purposes, we recommend you contact an authorized Snow Joe^® + Sun Joe^® dealer or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563).

Sharpening is necessary when:

• The sawdust looks like dust;
• Cutting becomes more difficult;
• The cut is not straight;
• Vibrations increase.

An authorized service center will sharpen the chain using the right tools to ensure minimum removal of material and even sharpness on all the cutting edges.

If you sharpen the chain yourself, use special round-section files with the right diameter depending on the type of chain (see "Chain Maintenance Table"). You need a certain amount of skill and experience to avoid damaging the cutting edges.

Sharpen the chain as follows (Fig. 32):

• Secure the bar firmly, with the chain mounted, in a suitable vise.
• Tighten the chain if it is loose.
• Mount the file in the guide and then insert it in the tooth at a constant angle from the cutting edge.
• Sharpen in a forward motion a few times and repeat this on all the cutting edges facing the same way (right or left).
• To move the chain forward, use a screwdriver.
• Turn the bar over in the vise and repeat on all the other cutting edges.
• Check that the depth limiter tooth does not stick out farther than the inspection tool and file any projecting parts with a flat file, rounding off the edges (Fig. 30).
• After sharpening, remove all traces of filing and dust and lubricate the chain in an oil bath. Replace the chain whenever:
  • The length of the cutting edges decreases to 5 mm or less;
  • There is too much play between the links and the rivets.

Guide Bar Maintenance

When the guide bar shows signs of wear, turn it over on the saw to distribute the wear for maximum bar life. Feathering or burring of the bar rails is a normal process of bar wear. You should smooth such faults with a file as soon as they occur.

Replace a bar with any of the following faults:

• wear inside the bar rails permitting the chain to lay over sideways
• bent guide bar
• cracked or broken rails

Chain Maintenance Table

Chain Sprocket

Regularly check the condition of the sprocket and replace it when wear exceeds 0.5 mm (Fig. 33).

Do not mount a new chain with a worn sprocket or vice-versa.

Daily Checklist, Cleaning and Storage

Daily Checklist

To help maintain your electric 2-in-1 pole + chain saw for optimum performance, we recommend you complete this checklist prior to each work session.

Do not plug in the power cord until you have completed all of the daily checks.

• Inspect for any visible damage to the chain, guide bar, or motor housing.
• Inspect the oil port and guide bar rails and clean them to remove any debris.
• Check the chain tension.
• Check the chain teeth for sharpness.
• Check the bar and chain oil level; fill with only new chain oil specifically formulated for chain saws.

NOTE: If you notice anything unusual, such as a vibration or or an odd sound, shut the saw OFF immediately. Remove the power cord and check the saw for any damage.

If you cannot find the cause of the problem or are uncertain what to do, then have the saw inspected by an authorized Snow Joe^® + Sun Joe^® dealer or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563) before using it.

• Remove the power cord and wait at least five minutes for the saw to cool before servicing or storing your unit.
• If you drop the saw, carefully inspect it for damage. If the guide bar is bent, the housing is cracked, the handle is broken, or if you see any other condition that may affect the saw's operation, DO NOT USE the tool. Instead, have it serviced at an authorized Snow Joe^® + Sun Joe^® dealer or call the Snow Joe^® + Sun Joe^® customer service center at 1-866-SNOWJOE (1-866-766-9563).

Cleaning

Use only mild soap and a damp cloth to clean the 2-in-1 pole + chain saw. Never let any liquid get inside the motor housing and NEVER immerse any part of the saw housing in liquid.

Storage

• Ensure that the guide bar cover is in place when storing.
• Do not store the 2-in-1 pole + chain saw near chemicals, such as fertilizers or other harsh solvents. Do not expose the plastic parts of the unit to brake fluids, gasoline, petroleum-based products, penetrating oils, or the like. These products are often highly corrosive and may cause permanent damage, weaken, or destroy the plastic parts of your unit.
• When not in use, your machine should be stored indoors in a dry and high or locked-up place, out of the reach of children.
