WARNING: Listen out for warn-

ing signals or shouts when you are wearing hearing protection. Always remove your hearing protection as soon as the engine stops. Important IMPORTANT! The machine is only designed for trimming grass. The only accessories you can operate with this engine unit are the cutting attachments we recommend in the chapter on Technical data. Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medi- cation that could affect your vision, your judgement or your co--ordination. Wear personal protective equipment. See in- structions under the heading Personal protective equipment. Never use a machine that has been modified in any way from its original specification. Never use a machine that is faulty. Carry out the checks, maintenance and service instruc- tions described in this manual. Some mainte- nance and service measures must be carried out by trained and qualified specialists. See instructions under the heading Maintenance. All covers and guards must be fitted before starting. Make sure the spark plug cap and lead are not damaged. Otherwise you could get an electric shock. The machine operator must ensure that no people or animals come closer than 15 metres while working. When several opera- tors are working in the same area, the safety distance should be at least 15 metres.

WARNING: Never allow children

to use or be in the vicinity of the machine. As the machine is equipped with a spring--loaded stop switch and can be started by low speed and force on the starter handle, even small children under some circum- stances can produce the force neces- sary to start the machine. This can mean a risk of serious personal inju- ry. Therefore remove the spark plug cap when the machine is not under close supervision.

WARNING: This machine pro-

duces an electromagnetic field during operation. Under some cir- cumstances, this field may interfere with active or passive medical implants. To reduce the risk of serious or fatal injury, we recom- mend persons with medical implants to consult their physician and the medical implant manufac- turer before operating this machine.

5GENERAL SAFETY PRECAUTIONS

IMPORTANT! All servicing and repair work on the machine requires special training. This is especially true of the machine’s safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of pro- fessional repairs and service. If the retailer who sells your machine is not a servicing dealer, ask him for the address of your near- est service agent. Machine’s safety equipment This section describes the machine’s safe- ty equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the “What is what” section to locate where this equipment is positioned on your machine. The life span of the machine can be re- duced and the risk of accidents can in- crease if machine maintenance is not car- ried out correctly and if service and/or re- pairs are not carried out professionally. If you need further information please contact your nearest service workshop. Throttle lock--out The throttle lock--out is designed to prevent accidental operation of the throttle control. When you press the lock--out (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle, the throttle control and the throttle lock--out both move back to their original positions. This movement is controlled by two independent return springs. This ar- rangement means that the throttle control is automatically locked at the idle setting. Press the throttle lock--out and make sure it returns to its original position when you re- lease it. Check that the throttle control and throttle lock--out move freely and that the return springs work properly. See instructions under the heading Start. Start the machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a standstill. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must be checked. See instructions under the heading Maintenance.

WARNING: Never use a machine

that has faulty safety equipment! Follow the control, maintenance and service instructions described in this section. If your machine fails any of these checks contact your service agent to get it repaired.

Make sure the throttle control is locked at the idle setting when the throttle lock--out is released.

A first aid kit should be carried by opera- tors of clearing saws, brushcutters or trim- mers. CLOTHING Wear clothes made of a strong fabric and avoid loose clothing that can catch on shrubs and branches. Always wear heavy, long pants. Do not wear jewelry, shorts sandals or go barefoot. Secure hair so it is above shoulder level.

6GENERAL SAFETY PRECAUTIONS

WARNING: Overexposure to

vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experi- ence symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin color or condition. These symptoms normally appear in the fingers, hands or wrists. The risk increases at low temperatures. In countries that have a warm and dry climate there is a significant risk of fire. We therefore fit certain mufflers with a spark arrestor mesh. Check whether the muffler on your machine is fitted with this kind of mesh. For mufflers, it is very important that you follow the instructions on checking, main- taining, and servicing your machine. Never use a machine that has a faulty muffler. Regularly check that the muffler is securely attached to the machine. Muffler The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. CAUTION! Muffler is fitted with a catalytic convertic designed to reduce harmful ex- haust gases. Cutting attachment guard This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment. Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked. Always use the recommended guard for the cutting attachment you are using. See the “Technical data” section. Use of incorrectly wound trimmer line or an incorrect cutting attachment increases the level of vibration.

WARNING: Never use a cutting

attachment without an approved guard. See the section on “Technical data”. If an incorrect or faulty guard is fitted this can cause serious personal injury. Muffler bolts

WARNING: Mufflers fitted with

catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire! Stop switch Make sure the engine stops when you push and hold the stop switch.

7GENERAL SAFETY PRECAUTIONS

Cutting equipment This section describes how to choose and maintain your cutting equipment in order to: S Obtain maximum cutting performance. S Extend the life of cutting equipment. Trimmer head S Only use the recommended cutting at- tachments. See the section on “Technical data”.

WARNING: A faulty cutting at-

tachment may increase the risk of accidents. IMPORTANT! Only use cutting attachments with the guards we recommend! See the section on “Technical data”. Refer to the instructions for the cutting attach- ment to check the correct way to load the trimmer line and the correct line diameter. IMPORTANT! Always ensure the trimmer line is wound tightly and evenly around the drum, other- wise the machine will generate harmful vibration.

WARNING: Always stop the en-

gine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the lead from the spark plug before you start to work on it. S Smaller machines generally require small trimmer heads and vice versa. This is be- cause when clearing using trimmer line the engine must throw out the trimmer line radially from the trimmer head and overcome the resistance of the grass being cleared. S The length of the trimmer line is also im- portant. A longer trimmer line requires greater engine power than a shorter trimmer line of the same diameter. S Make sure that the cutter on the trimmer guard is intact. This is used to cut the trimmer line to the correct length. S To increase the life of the trimmer line it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.

WARNING: The inside of the

muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.

WARNING: Bear in mind that:

Engine exhaust fumes contain car- bon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or any- where that is poorly ventilated. The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near com- bustible material! 8ASSEMBLY Fitting the trimmer guard and trimmer head (Model 128L) S Fit the correct trimmer guard (A) for use with the trimmer head. Hook the trimmer guard/combination guard onto the fitting on the shaft and secure with the bolt (D).

TE: Make sure unit is assembled cor- rectly as shown in this manual. Fitting the loop handle S Position the handle on the shaft. Note that the handle must be mounted be- tween the two arrows on the shaft. S Fit the screw, securing plate and wing nut as shown in the diagram. S Tighten the wing nut.

S Fit the drive disc (B) on the output shaft. S Turn the shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing. S Insert hex wrench (C) in the hole to lock the shaft. S Screw on the trimmer head (H) in the op- posite direction to the direction of rota- tion.

S To dismantle, follow the instructions in the reverse order. Fitting the trimmer guard and trimmer head (Model 128C) S Fit the correct trimmer guard (A) for use with the trimmer head. Hook the trimmer guard/combination guard onto the fitting on the shaft and secure with the nut (B).

S Fit the dust cup (C) on the shaft. The nut must be completely covered by the dust cup. S Hold the dust cup with a wrench to pre- vent the shaft from rotating. S Screw the trimmer head (D) onto the shaft. S To dismantle, follow the instructions in the reverse order.

9FUEL HANDLING Fuel safety Never start the machine:

1. If you have spilled fuel on it. Wipe off the

spillage and allow remaining fuel to evapo- rate.

2. If you have spilled fuel on yourself or your

clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

3. If the machine is leaking fuel. Check regu-

larly for leaks from the fuel cap and fuel lines. Transport and storage S Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked flames, for example, from electri- cal machinery, electric motors, electrical relays/switches or boilers. S When storing and transporting fuel al- ways use approved containers intended for this purpose. S When storing the machine for long peri- ods the fuel tank must be emptied. Con- tact your local petrol station to find out where to dispose of excess fuel. S Ensure the machine is cleaned and that a complete service is carried out before long--term storage. S In order to prevent unintentional starting of the engine, the spark plug cap must always be removed during long--term storage, if the machine is not under close supervision and when performing all service measures. S Secure the machine during transport. Fuel CAUTION! The machine is equipped with a two--stroke engine and must always be run using a mixture of petrol and two-stroke engine oil. It is important to accurately mea- sure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Petrol CAUTION! Always use a good quality pet- rol/oil mixture (at least 90 octane). Use low--emission petrol, also known as alkylate petrol, if it is available. S The lowest octane recommended is 90. If you run the engine on a lower octane than 90, it can result in knocking. This gives rise to a high engine temperature, which can result in serious engine damage. S When working at continuous high revs, a higher octane rating is recommended. Two--stroke oil S For best results and performance, use HUSQVARNA two--stroke oil, which is specially formulated for our two--stroke engines. Mixture 1:50 (2%). S If HUSQVARNA two--stroke oil is not avail- able, you may use another two-stroke oil of good quality that is intended for air cooled engines. Contact your dealer when select- ing an oil. Mixing ratio 1:33 (3%). S Never use two--stroke oil intended for water--cooled outboard engines, sometimes referred to as outboard oil. S Never use oil intended for four--stroke engines.

WARNING: Take care when han-

dling fuel. Bear in mind the risk of fire, explosion and inhaling fumes. 5 0,10 0,15 10 0,20 0,30 15 0,30 0,45 20 0,40 0,60 Petrol, litre Two--stroke oil, litre 2% (1:50) 3% (1:33)

WARNING: Fuel and fuel fumes

are highly inflammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ven- tilation. 10FUEL HANDLING S Always start by flling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. S Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank. S Do not mix more than one month’s sup- ply of fuel at a time. S If the machine is not used for some time, the fuel tank should be emptied and cleaned.

WARNING: The catalytic con-

verter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapors. Fuelling

WARNING: Taking the following

precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel. Always shut off the engine before refueling. Always stop the engine and let it cool for a few minutes before refu- elling. When refueling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refueling. Always move the machine away from the refueling area before starting. Min. 3 m

S Always mix the petrol and oil in a clean container intended for fuel. S Clean the area around the fuel cap. Contamination in the tank can cause operating problems. S Ensure that the fuel is well mixed by shak- ing the container before filling the tank.

11STARTING AND STOPPING

Repeat pulling the cord until the engine attempts to start. Move the blue engine choke lever to the ½ position. Pull starter rope until engine runs. Move the blue en- gine choke lever to the opened position.

WARNING: When the engine is

started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately.

WARNING: The complete clutch,

clutch cover, and shaft must be fitted before the machine is started, otherwise parts could come loose and cause personal injury. Always move the machine away from the refueling area before starting. Place the machine on a flat surface. Ensure the cutting at- tachment cannot come into contact with any object. Make sure no unauthorized persons are in the working area, otherwise there is a risk of serious personal injury. The safety distance is 15 meters. Starting and stopping

12STARTING AND STOPPING

Warm engine With a warm engine, move the blue engine choke lever to the ½ position. Pull starter rope until engine runs. Move the blue en- gine choke lever to the opened position. CAUTION! Do not put any part of your body in marked area. Contact can result in burns to the skin, or electrical shock if the spark plug cap has been damaged. Always use gloves. Do not use a machine with dam- aged spark plug cap. CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine. NOTE: If engine dies, return blue engine choke lever to the closed position and repeat starting steps. Stopping Stop the engine by pushing and holding the stop switch in the STOP position until the engine stops. CAUTION! The stop switch automatically returns to the start position. In order to pre- vent unintentional starting, the spark plug cap must be removed from the spark plug when assembling, checking and/or per- forming maintenance.

WARNING: When the engine is

started with the choke in the closed position the cutting attachment will start to rotate immediately. 13WORKING TECHNIQUES General working instructions IMPORTANT! This section describes the basic safety pre- cautions for working with trimmers. If you encounter a situation where you are uncer- tain how to proceed you should ask an ex- pert. Contact your servicing dealer. Avoid all usage which you consider to be beyond your capability. You must understand the difference between forestry clearing, grass clearing and grass trimming before use. Basic safety rules

S To ensure that people, animals or other things cannot affect your control of the machine. S To ensure that people, animals, etc., do not come into contact with the cut- ting attachment or loose objects that are thrown out by the cutting attach- ment. S CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

2. Do not use the machine in bad weather,

such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.

3. Make sure you can move and stand safely.

Check the area around you for possible ob- stacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

4. Switch off the engine before moving to

5. Never put the machine down with the engine

running or while the cutting attachment is rotating. Basic working techniques S Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage. Grass trimming with a trimmer head Trimming S Hold the trimmer head just above the ground at an angle. It is the end of the trimmer line that does the work. Let the trimmer line work at its own pace. Never press the trimmer line into the area to be cut. S The trimmer line can easily remove grass and weeds up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts.

WARNING: Sometimes branches

or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.

WARNING: Neither the operator

of the machine nor anyone else may attempt to remove the cut ma- terial while the engine is running or the cutting equipment is rotating, as this can result in serious injury. Stop the engine and cutting equip- ment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burned if you touch it.

WARNING: Watch out for

thrown objects. Always wear ap- proved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unautho- rised persons at a distance. Chil- dren, animals, onlookers and help- ers should be kept outside the safety zone of 15 m. Stop the ma- chine immediately if anyone ap- proaches. Never swing the ma- chine around without first checking behind you to make sure noone is within the safety zone. 14WORKING TECHNIQUES S Reduce the risk o

damaging plants by shortening the trimmer line to 4--4 1/2 inches (10--12 cm) and reducing the engine speed. S When trimming you should use less than full throttle so that the trimmer line lasts longer and to reduce the wear on the trimmer head. Clearing S The clearing technique removes all un- wanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the trimmer line strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the trimmer line. S The trimmer line wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into con- tact with trees and wooden fences. Cutting S The trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the trimmer line parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool. S Do not allow the trimmer head to con-- stantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head. Sweeping S The fan effect of the rotating line can be used for quick and easy clearing up. Hold the trimmer line parallel to and above the area to be swept and move the tool to and fro. S When cutting and sweeping you should use full throttle to obtain the best results.

WARNING: Neither the operator

of the machine nor anyone else may attempt to remove the cut material while the engine is running or the trimmer line is rotating, as this can result in serious injury. Stop the engine and trimmer head before you remove material that has wound around the drive shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burned if you touch it.

WARNING: Watch out for thrown

objects. Always wear eye protection. Never lean over the cutting attach- ment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorized persons at a dis- tance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone approaches. 15MAINTENANCE Carburetor Your Husqvarna product has been designed and manufactured to specifications that re- duce harmful emissions. After the engine has used 8--10 tanks of fuel, the engine will be run--in. To ensure that it continues to run at peak performance and to minimize harm- ful exhaust emissions after the run--in peri- od, ask your servicing dealer to adjust your carburetor. The owner is responsible

or- mance of all required maintenance as defined in the operator’s manual.

WARNING: The complete clutch,

clutch cover, and shaft must be fitted before the machine is started, otherwise parts could come loose and cause personal injury. Function S The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. S The T--screw regulates the throttle setting at idle speed. If the T--screw is turned clockwise this gives a higher idle speed; turning it counterclockwise gives a lower idle speed. Basic setting S The basic carburetor settings are ad- justed during testing at the factory. Fine adjustment should be carried out by a skilled technician. Rec. idle speed: See “Technical data” section. Recommended max. speed: See “Technical data” section. Fine adjustment of the idle speed--T Adjust the idle speed using the idle adjust- ment screw--T if it is necessary to readjust. First, turn the idle adjustment screw--T clockwise until the cutting attachment starts to rotate. Then, turn the screw counter- clockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every posi- tion. The idle speed should also be well below the speed at which the cutting attach- ment starts to rotate. CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned counterclockwise until the cutting attachment stops. Idle Speed Screw--T

WARNING: If the idle speed can-

not be adjusted so that the cutting attachment stops, contact your ser- vicing dealer. Do not use the ma- chine until it has been correctly ad- justed or repaired. Unit/Maintenance Safety Disconnect the spark plug before perform- ing maintenance, except carburetor adjust- ments. Muffler CAUTION! Muffler is fitted with a catalytic converter designed to reduce harmful ex- haust gases. The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and com- bustible material. Mufflers are equipped with a special spark arrestor mesh. You should clean the mesh at least once a month. This is best done with a wire brush. If the mesh is damaged it should be replaced. If the mesh is fre- quently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston. Muffler bolts CAUTION! Never use a machine that has a faulty or loose muffler. Ensure the muffler bolts are tight. Spark arrestor mesh 16MAINTENANCE

WARNING: The inside of the

muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.

WARNING: Bear in mind that:

Engine exhaust fumes contain car- bon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or any- where that is poorly ventilated. The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near com- bustible material! Spark plug The spark plug condition is influenced by: S Incorrect carburetor adjustment. S An incorrect fuel mixture (too much or in- correct type of oil). S A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operat- ing problems and starting difficulties. If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,6 mm. The spark plug should be replaced after about a month in operation or earlier if necessary. CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. 0,6 mm Air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid: S Carburetor malfunctions S Starting problems S Loss of engine power S Unnecessary wear to engine parts S Excessive fuel consumption Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty. Cleaning the air filter Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Rinse thoroughly. Ensure that the filter is dry before refitting it. An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced. Bevel gear (128L) The bevel gear is filled with the right quan- tity of grease at the factory. However, be- fore using the machine you should check that the bevel gear is filled three--quarters full with grease. Use HUSQVARNA special grease. The grease in the bevel gear does not nor- mally need to be changed except if repairs are carried out.

WARNING: Mufflers fitted with

catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire! 17MAINTENANCE Maintenance schedule The following is a list of the maintenance that must be performed on the machine.
