SAFETY INSTRUCTIONS

Personal protective equipment

• An edger used incorrectly or carelessly can become a dangerous tool, that can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the content of this manual.
• When using an edger, personal protective equipment approved by the appropriate authorities must be used. Personal protective equipment does not eliminate the risk of accidents, however, it can reduce the effects of an injury in the event of an accident. Ask your dealer for help when choosing protective equipment.

Remove your hearing protection as soon as you stop the engine, so that you can hear any noises or warning signals.

GLOVES
Gloves should be worn when necessary, e.g., when assembling cutting equipment.

EAR PROTECTION
Ear protection offering sufficient dampening effect should be used.
EYE PROTECTION
Blows from branches or objects thrown by the rotating cutting equipment can damage the eyes.

BOOTS
Use anti-slip and stable boots.

CLOTHING
Wear clothes made of a strong fabric and avoid loose clothing that can catch on shrubs and branches. Always wear heavy duty tong pants. Do not wear jewellery, shorts, sandals or go barefoot. Secure hair so it is above shoulder level.

FIRST AID KIT
A first aid kit should be carried by operators of the edger.

The machine's safety equipment

This section describes the machine's safety equipment, its function and how checks and maintenance are carried out to ensure that it operates correctly. (See the chapter "What is what" to locate where this equipment is positioned on your machine.)

Never use a machine with defective safety equipment. Follow the control, maintenance and service instructions described in this section.

1. Throttle trigger lock
   The throttle trigger tock is designed to prevent the throttle from accidentally being engaged. When the trigger tock (A) is pressed into the handle (= when you hold the handle) the throttle (B) is released.
   When the grip on the handle is released the throttle and the throttle trigger tock return to their original positions. This takes place via two independent return spring systems. This means that the throttle is automaticaly locked in the "idling" position.
   
2. Stop switch
   The stop switch should be used to stop the engine.
   
3. Cutting attachment guard
   This guard is intended to prevent objects from being thrown towards the operator and to protect the operator from unintentional contact with the cutting attachment.
   
4. Vibration damping system
   Your machine is equipped with a vibration damping system, which is designed to give as vibration-free and comfortable use as possible.
   The use of incorrect cutting equipment increases the level of vibration.
   The machine's vibration damping system reduces the transfer of vibrations between the engine unit/cutting equipment and the machine's handle unit.
   
   
   Over exposure to vibrations can result in blood-vessel or nerve injury to persons suffering with blood circulation problems. Seek medical attention if you experience physical symptoms that can be related to over exposure to vibrations. Examples of such symptoms are "numbness", lack of feeling, "tickling", "pricking", "pain", lack of or a reduction in normal strength, changes in the colour of the skin or its surfaces. These symptoms normally appear in the fingers, hands or wrists.
5. Muffler
   The muffler is designed to give the to west possible noise level and to direct the engine's exhaust fumes away from the operator. Mufflers equipped with a catalytic converter are also designed to reduce the hazardous substances in the exhaust fumes.
   In countries that have a warm and dry climate the risk of fire is obvious. We have therefore fitted certain mufflers with a spark arrest screen. Make sure that your muffler is fitted with this kind of screen.
   It is extremely important that the instructions for checking, maintaining and servicing the muffler are followed. (See the section "Control, maintenance and service of the machine's safety equipment').
   
   
   The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!
   
   Mufflers fitted With catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!
6. Cutting equipment
   The blade is designed and processed to withstand toads that edging of a lawn involves.
   
7. Locking nut
   The locking nut secures the cutting equipment on the output shaft.
   

Control, maintenance and service of the machine's safety equipment

• All service and repairs to the machine require special training.
• This applies especially to the machine's safety equipment. If the machine does not meet any of the controls listed below you should contact your service workshop.
• The purchase of one of our products guarantees that professional repair and servicing will be carried out on it. If the point of purchase is not one of our servicing dealers, please ask for details of the closest service workshop.

1. Throttle trigger lock
   
   • Check that the throttle is locked in the "idling position" when the throttle trigger lock is in its original position.
   • Press in the throttle trigger lock and make sure it returns to its original position when released.
   • Ensure that the throttle and throttle trigger lock move easily and that their return spring systems function.
   • See section "Start". Start the machine and apply full throttle. Release the throttle and check that the cutting equipment stops and remains at a standstill. If the cutting equipment rotates with the throttle in the idling position then the carburetor's idling setting must be checked. See chapter "Maintenance".
2. Stop switch
   • Start the engine and make sure that the engine stops when the stop switch is moved to the stop position.
     
3. Cutting attachment guard
   
   • Ensure that the guard is undamaged and is not cracked.
   • Replace the guard if it has been exposed to impact or is cracked.
   • Always use the prescribed blade and guard combination, see chapter "Technical data".
4. Vibration damping system
   
   • Check the vibration damping element regularly for material cracks and distortion.
   • Check that the vibration damping element is undamaged and securely attached.
5. Muffler
   
   1. Never use a machine that has a defective muffler.
   2. Check regularly that the muffler is secure.
   3. If your muffler is fitted with a spark arrest screen then it should be cleaned regularly. A blocked screen leads to the engine overheating with serious damage as a result. Never use a muffler with a detective spark arrest screen.
6. Cutting equipment
   
   The two basic rules:
   1. Only use the cutting equipment we recommend! See chapter "Technical data".
   2. Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced.

   
   Always stop the engine before starting work on any part of the cutting equipment. This continues to rotate even after the throttle has been released. Ensure that the cutting equipment has stopped completely and remove the cable from the spark plug before you start to work on it.

7. Locking nut
   
   • Protect your hand from injury when assembling, use the blade guard as protection when tightening with a socket spanner. Tighten the nut by turning against the direction of rotation. Loosen the nut by turning in the direction of rotation. (NOTE! the nut has a left-hand thread).
   • Tighten the nut using a socket spanner, 35 - 50 Nm (3.5 - 5 kpm).

NOTE!
The locking nut's nylon lock must not be so worn that it can be turned by hand. The tock shalt hold at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.

Never use a machine with defective safety equipment. The safety equipment should be maintained as described in this section. If your machine does not meet any of these controls you should contact your service workshop.

General working instructions

• This section takes up the basic safety precautions for working with the edger,
• If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop.
• Avoid all usage which you consider to be beyond your capability.

Basic safety precautions

1. Observe your surroundings:
   • To ensure that people, animals or other things cannot affect your control of the machine.
   • To ensure that the above mentioned do not come into contact with the cutting equipment or objects that can be thrown by the cutting equipment.
   • NOTE! Never use a machine without the possibility of calling for help in the event of an accident.
2. Avoid usage in unfavourable weather conditions. For example, thick fog, heavy rain, strong winds or extreme cold, etc. To work in bad weather conditions is tiring and can create dangerous circumstances, e.g. slippery surfaces.
3. Make sure you can walk and stand safely. Look out for any obstacles with unexpected movement (roots, stones, branches, pits, ditches, etc.). Take great care when working on sloping ground.
4. The engine should be switched off before moving.
5. Never put the machine down with the engine running unless you have good sight of it.

Basic working techniques

Safety instructions while working

• Always ensure you have a safe and firm foothold.
• Always hold the machine with both hands. Hold the machine of the right-hand side your the body.
• Make sure your hands and feet do not come into contact with the blade when the engine is running.
• When the engine is switched off, keep your hands and feet away from the blade until it has stopped.
• Always cut edges at full throttle.
• Always keep the blade close to the ground.
• Always drop to idling speed after each working operation. Longer periods running at full throttle without loading the engine (that is without resistance, which the engine feels from the cutting equipment when trimming) can lead to serious engine damage.
• Be especially careful when pulling the edger towards you during work.
• If heavy vibrations occur, stop the engine. Remove the spark plug cable from the spark plug. Check that the machine is not damaged. Repair any damage.

Sometimes grass and stones can collect in the blade guard and blade. Always stop the engine when cleaning.

Beware of thrown objects. Always wear eye protection. Never lean over the blade guard. Stones rubbish etc. can be thrown up into the eyes resulting in blindness or other serious injury,
Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be outside the safety zone of 15 meters (50 feet); Stop the machine immediately if anyone approaches.
The bevel gear unit can get hot during use and may remain so for a while afterwards. There is a risk of slight burns if you touch it.

Safety instructions after completing work

• Ensure the blade has stopped before cleaning, carrying out repairs or an inspection. Remove the spark plug cable from the spark plug.
• Wear heavy-duty gloves when carrying out repairs on the edger.
• Store the machine out of reach of children.
• Only use original spare parts with repair.

ASSEMBLY

Assembling the loop handlebar

• Position the handle on the shaft. Note that the handle must be mounted below the arrow on the shaft.
• Fit the bolt, securing plate and wing nut as shown in the diagram.
• Tighten the wing nut.

Assembling the angle gear

• Assemble the angle gear back on the supporting tube. Turn the blade so that the drive shaft engages in the angle gear.
• Position the angle gear so that its slot is aligned with the line on the supporting tube.
• Firmly tighten the screw.

Assembling the blade

Fit the blade as follows:

1. Fit the drive disc (A) on the outgoing shaft. Make sure that the edge that fits in the hole of the blade is facing outward.
2. Block the blade rotation by inserting locking pin in the hole behind the blade guard engaging it in the corresponding hole in the drive disc.
3. Fit the blade (B) on the drive disc.
4. Fit the support flange (C). The support flange must be fitted with its outer edge hard up against the blade.
5. Fit the Iocknut (D). NOTE! The Iocknut has left-hand threads. The tightening torque of the Iocknut is 35 - 50 Nm.
6. Remove the locking pin.

NOTE! Do not forget to remove the locking pin before using the machine.

Under no circumstances may the edge cutter blade be used without the blade guard fitted.

FUEL HANDLING

Fuel mixture

NOTE!
The edger is fitted with two-stroke engines and must always be run on a mixture of gasoline and two-stroke oil. To ensure the correct mixture proportions it is important to measure the quantity of oil accurately. When mixing small amounts of fuel small discrepancies in the amount of oil has a great bearing on the proportions of the fuel mixture.

Always provide good ventilation when handling fuel.

Gasoline

NOTE!
Always use high grade unleaded Oil mixed gasoline (minimum 87 RON). Leaded fuel will destroy the catalytic converter and it will no longer serve its purpose.

• This engine is certified to operate on unleaded gasoline.
• The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 so-called "knocking" can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.
• When working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

• For the best results use HUSQVARNA two-stroke oil which has been specially developed for two-stroke engines.
  Mixing ratio 1:50 (2%).
• Never use two-stroke oil intended for water cooled outboard motors, so-called outboard motor oil.
• Never use oil intended of four-stroke engines.

Mixture

• Always mix gasoline and oil in a clean container intended for fuel.
• Always start by filling half the quantity of gasoline required. Then add the entire oil quantity. Mix (shake) the fuel mixture. Fill the remaining quantity of gasoline.
• Mix (shake) the fuel mixture carefully before filling in the machine's fuel tank.
• Do not mix more than max. one month's supply of fuel.
• If the clearing saw is not used for a long period of time, the fuel tank should be emptied and cleaned.
• This engine is certified to operate on unleaded gasoline.

The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when handling the saw near flammable substances or vapors.

Fueling

The following precautions reduce the risk of fire:
Do not smoke or place any sources of heat in the vicinity of the fuel. Never refuel when the engine is running. Always stop the engine and let it cool for a few minutes before. refueling. Open the fuel cap slowly when fueling so that any over pressure is released slowly. Tighten the fuel cap carefully after refueling. Always move the machine from the fueling place before starting.

• Clean around the fuel cap. Contamination in the tank can disrupt operations.
• Ensure that the fuel is well mixed by shaking the container before filling the tank.

START AND STOP

Control before starting

For reasons of safety follow these recommendations!

• Check that the support flange is not cracked due to fatigue or due to being tightened too much. Replace the support flange if it is cracked.
• Ensure that the nut has not lost its tightening capacity The nut lock shall have a locking torque of at least 1.5Nm. The nut's tightening torque shall be 35-50 Nm.
• Check that the blade and the blade guard are not damaged or cracked. Replace the blade or blade guard if it has been exposed to impact or if it is cracked.

Start and stop

The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury.
Always move the machine from the filling position before starting. Place the machine on a flat surface. Make sure the blade cannot come into contact with any object. Make sure that no unauthorised persons are in the working area, otherwise there is a risk of serious personal injury. The safety distance is 15 metres.

Cold engine
IGNITION:
Set the stop switch to the start position.
CHOKE:
Set the choke control in the choke position.
AIR PURGE:
Press the air purge diaphragm repeatedly until fuel begins to fill the diaphragm. The diaphragm need not be completely filled.

Warm engine
Use the same starting procedure as for the cold engine, but do not set the choke control in the choke position. The start throttle position is obtained by setting the choke control in the choke position and then returning it to its original position.

Stop
The engine is stopped by switching off the ignition.

When the engine starts with the choke lever in the choke or starter throttle position the cutting toot (blade or trimmer) starts to rotate immediately.

Start
Press the machine body against the ground using your left hand (NOTE! Not your foot). Grip the starter handle slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord. Reset the choke control as soon as the engine fires and repeat until the engine starts. When the engine starts quickly apply full throttle and the start throttle will automatically disengage.

NOTE! Do not pull the starter cord out completely and do not release the starter cord from the fully extended position. This can damage the machine.

MAINTENANCE

Carburetor

Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions.
After your unit has been run 8-10 tanks of fuel the engine has broken in. To ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing dealer, who has a revolution counter at his disposal, to adjust your carburetor for optimum operating conditions.

The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury.

Operation

• The carburetor governs the engine's speed via the throttle. Air/fuel is mixed in the carburetor. The air/fuel mixture is adjustable. To take advantage of the engine's optimal output the adjustment must be correct.
• The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, gasoline and the type of 2-stroke oil
• The carburetor is equipped with three adjustment possibilities:
  
  L = Low speed needle
  H = High speed needle
  T = Idle speed adjuster screw
• The fuel quantity in relation to the air flow permitted by the throttle opening is adjusted using the L and H-needles. Turning the needles clockwise gives a leaner fuel mixture (less fuel) and turning them anti-clockwise gives a richer fuel mixture (more fuel). A leaner mixture gives high revs while a richer mixture give less revs.
• The T-screw regulates the position of the throttle while the engine is idling. Turning the screw clockwise gives a higher idling speed while turning it anti-clockwise gives a lower idling speed.

Basic setting

• The carburetor is set to its basic setting when test run at the factory. The basic setting should be kept during the machine's first working hours. Thereafter the carburetor should be finely adjusted. Fine adjustment should be carried out by a skilled technician.

NOTE! If the cutting attachment rotates/moves white the engine is idling the T-screw should be turned anti-clockwise until the cutting attachment stops.
Rec. idling speed: 2700 rpm.
Recommended max. speed: See "Technical data".

If the idling speed cannot be adjusted so that the cutting attachment stops, contact your service. workshop. Do not use the machine until it has been correctly adjusted or repaired.

Fine adjustment

• When the machine has been "run-in" the carburetor should be finely adjusted. The fine adjustment should be carried out by qualified person. First adjust the L-jet, then the idling screw T and then the H-jet.

Conditions

• Before any adjustments are made the airtilter should be clean and the airfilter cover fitted. Adjusting the carburetor while a dirty airfilter is in use will result in a leaner mixture when the filter is finally cleaned. This can give rise to serious engine damage.
• Carefully turn the L and H needle to the mid point between fully turned in and fully turned out.
• Do not attempt to adjust the needles beyond the stops as damage can occur.
• Now start the machine according to the starting instructions and run it warm for 10 minutes.

NOTE! If the cutting attachment rotates/moves the T screw should be turned anti-clockwise until the cutting attachment stops.

Low speed needle L
Try to find the highest idling speed, turning the tow speed needle L dock wise respectively counter-clockwise. When the highest speed has been found, turn the low speed needle L 1/4 turn counterclockwise.

NOTE! If the cutting attachment rotates/moves in the idling position, turn the idling speed screw T counterclockwise until the cutting attachment stops.

Final setting of the idling speed T
Adjust the idling speed with the screw T, if it is necessary to readjust. First turn the idle speed adjusting screw T clockwise until the cutting attachment starts to rotate/ move.
Then turn, counter-clockwise until the cutting attachment stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the cutting attachment starts to rotate/move.

Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the cutting attachment stops. Do not use the machine until it has been properly adjusted or repaired.

High speed needle H

The high speed needle H influences the power, speed, temperature and fuel consumption of the machine. A too lean adjusted high speed needle H (high speed needle H closed too much) gives over revs and damages the engine. Do not yet the machine run at full speed for more than 10 seconds.
Turn the high speed needle very slowly clockwise until engine speed is reduced.
Thereafter turn the high speed needle very slowly counterclockwise and stop when the engine begins to run roughly. Then turn the high speed needle slowly the minimum amount clockwise until the engine runs smoothly.
The high speed needle H is correctly set when the machine "4-cycles" a little. If the machine "whistles" the setting is too lean. If there is too much smoky exhaust gas at the same time as the machine "4- cycles" much, the setting is too rich.

NOTE! For optimum setting of the carburetor, contact a qualified servicing dealer who has a revolution counter at his disposal.

Correctly adjusted carburetor
A correctly adjusted carburetor means that the machine accelerates without hesitation and the machine 4-cycles a little at max speed. Furthermore, the cutting attachment must not rotate/move at idling.
A too lean adjusted low speed needle L may cause starting difficulties and bad acceleration. A too lean adjusted high speed needle H gives lower power = less capacity, bad acceleration and/or damage to the engine. A too rich adjustment of the two speed needles L and H gives acceleration problems or too low working speed.

Muffler with catalytic converter

A muffler fitted with a catalytic converter reduces the extent of the following substances in the exhaust fumes:

• Hydrocarbons (HC). Some hydrocarbons in gasoline and the exhaust are carcinogenic.
• Nitric oxides (NO). Irritating for the breathing air-ways.
• Aldehydes. The most common formaldehyde, is carcinogenic and causes hypersensitiveness.

NOTE! The level of carbon monoxide is not reduced. This is an odourless and extremely poisonous substance. Therefore avoid exposure without good air circulation.
The muffler is also designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed towards a dry or inflammable material Some mufflers are fitted with a speciat spark arrest screen. If your machine is fitted with this type of muffler then the screen should be cleaned at least once a week. This is done using a wire brush. If the screen is damaged in any way it should be replaced. If the screen is blocked this will result in engine overheating and damage to the cylinder and piston.

NOTE!
Never use a machine with a defective muffler.

Mufflers fitted with catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!

The coating online the catalytic element can be hazardous to health if consumed. Wear gloves when carrying out service work on the catalytic converter.

Cooling system

To maintain as tow operating temperature as possible the engine is equipped with a cooling system.
The cooking system consists of:

1. An air intake on the starter unit.
2. Cooling fins on the flywheel.
3. Cooling fins on the cylinder
4. Cylinder cover (leads cold air onto the cylinder).

Clean the cooling system using a brush at least once a week, in difficult conditions more often.
A dirty or blocked cooling system leads to the engine overheating resulting in damage to the cylinder and piston.

Spark plug

The condition of the spark plug is affected by:

• An incorrect carburetor setting.
• An incorrect fuel mixture (too much or faulty oil).
• A dirty air filter.

These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties.
If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary.
NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston.

Air filter

The air filter should be cleaned regularty removing dust and dirt to avoid:

• carburetor malfunction
• starting problems
• reduced engine power
• unnecessary wear to engine parts
• abnormal fuel consumption

Clean the filter after every 25 hours or more regutarly if operating conditions are exceptionally dusty.

Cleaning the air filter
Dismantle the air fitter cover and remove the air fitter. Wash in clean, warm soapy water. Ensure that the filter is dry before refitting. An air fitter used for a long period of time can never be cleaned completely. Therefore it is necessary to replace the filter from time to time with a new fitter. A damaged air filter must always be replaced.
If the machine is used in dusty conditions the air filter should be soaked in oil, see the section on "Oiling the air filter'.

Oiling the air filter
Always use HUSQVARNA filter Oit, order no. 503 47 7301. The filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. Put the filter in a ptastic bag and the pour the filter Oit over it. Knead the ptastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the ptastic bag and pour off the excess before fitting the filter on the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom.

Angle gear

The angle gear is filed with a sufficient quantity of grease at the factory. However, before using the machine you should check that the angle gear is filled to 3/4 with grease. Use HUSQVARNA speciat grease.
Normafly, the grease does not need to be changed except when repairs are carried out.

Lubricating the flexible drive axle

Inside the edger's drive shaft is a flexible drive axle. The flexible drive axle should be regularty lubricated after 30 hours of operation. Loosen the two screws on the angle gear and remove it. The flexible drive axle is easity removed from the shaft by taking a firm grip on the axle end. Lubricate the flexible drive axle over its entire length and reinsert it in the shaft. Turn the axle while inserting it so that it correctly engages in the clutch. Replace the angle gear on the drive axle shaft and tighten the two screws.

Adjusting the edger's cutting depth

The cutting depth should be adjusted before starting work.

• Loosen the locking handle (A) and rotate the guard by moving the locking handle backwards or forwards. If the locking handle is moved forwards (from the machine) the cutting depth is increased. If the locking handle is moved backwards (towards the machine) the cutting depth is reduced.
• Adjust the cutting depth.
• Lock the locking handle.

Always bear the machine on the right side of the body. Always wear protective glasses, long trousers and heavy-duty shoes when using the machine. Observe your surround. ings, ensure people and animals do not come in the immediate vicinity or can be hit by thrown objects. Apply full throttle before the blade starts to work on the soil.
NOTE: Use only HUSQVARNA reptacement parts. Use of other brands of reptacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by HUSQVARNA.
