INTRODUCTION Dear customer! Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant.

GENERAL SAFETY PRECAUTIONS 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. ! WARNING! Listen out for warning signals or shouts when you are wearing hearing protection. Always remove your hearing protection as soon as the engine stops. HEARING PROTECTION Wear hearing protection that provides adequate noise reduction.
GENERAL SAFETY PRECAUTIONS Machine′s safety equipment Press the throttle lockout and make sure it returns to its original position when you release it. This section describes the machine′s safety 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.
GENERAL SAFETY PRECAUTIONS 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. Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.
GENERAL SAFETY PRECAUTIONS If the muffler on your machine is fitted with a spark arrestor screen this must be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage. Cutting equipment This section describes how to choose and maintain your cutting equipment in order to: • Reduce the risk of blade thrust. • Obtain maximum cutting performance. • Extend the life of cutting equipment.
ASSEMBLY Fitting the loop handle • Unscrew the knob and plastic cover from the handle mounting. • Place the loop handle and handle holder on the handle mounting. Fit the knob and plastic cover. Do not overtighten. Assembling the cutting equipment ! ! • Put on the shoulder strap and hang the trimmer from the support hook. Now make a final adjustment so that the trimmer is in a comfortable working position when it hangs from the shoulder strap. Tighten the knob.
ASSEMBLY • Fit the nut (G). Tighten the nut to a torque of 35-50 Nm (3.5-5 kpm). Use the socket spanner in the tool kit. Grasp the handle of the spanner as close to the trimmer guard as possible. To tighten the nut, turn the spanner in the opposite direction to the direction of rotation (Caution! lefthand thread). • Fit the bottom half of the trimmer head (K) to the cover (I) by pressing them together, with the cut-outs on the bottom half aligned with the catches on the cover.
FUEL HANDLING Fuel safety Gasoline Never start the machine: 1 If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 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 regularly for leaks from the fuel cap and fuel lines.
FUEL HANDLING Fueling Mixing • Always mix the gasoline and oil in a clean container intended for fuel. • Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline. • ! Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank. WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel.
STARTING AND STOPPING Check before starting Cold engine Ignition: Set the stop switch to the start position. Choke: Set the choke control in the choke position. • Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked. • Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm.
STARTING AND STOPPING Starting Hold the body of the machine on the ground using your left hand (CAUTION! Not with 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. Repeat pulling the cord until the engine starts. When the engine starts. return choke control to run position and apply full throttle; the throttle will automatically disengage from the start setting.
WORKING TECHNIQUES General working instructions 6 Always hold the machine with both hands. Hold the machine on the right side of your body. 7 Keep the cutting attachment below waist level. 8 The engine must be switched off before moving. 9 Never put the machine down with the engine running unless you have it in clear sight. IMPORTANT! This section takes up the basic safety precautions for working with a trimmer.
WORKING TECHNIQUES Grass trimming with a trimmer head Sweeping • The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro. • When cutting and sweeping you should use full throttle to obtain the best results. Trimming • Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace.
MAINTENANCE Carburetor Basic setting Your Husqvarna product has been designed and manufactured to specifications that reduce 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 minimise harmful exhaust emissions after the running-in period, ask your dealer/service workshop (who will have a rev counter at their disposal) to adjust your carburettor.
MAINTENANCE Fine adjustment of the idle speed T Correctly adjusted carburetor Adjust the idle speed using the idle adjustment 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 anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position.
MAINTENANCE On mufflers without a catalytic converter the screen should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the screen should be checked, and if necessary cleaned, monthly. If the screen is damaged it should be replaced. If the screen is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the muffler.
MAINTENANCE Spark plug The spark plug condition is influenced by: • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating 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.
MAINTENANCE Maintenance schedule The following is a list of the maintenance that must be performed on the machine. Most of the items are described in the Maintenance section. The user must only carry out the maintenance and service work described in this manual. More extensive work must be carried out by an authorised service workshop. Maintenance Daily maintenance Clean the outside of the machine. X Make sure the throttle trigger lock and the throttle function correctly from a safety point of view.
