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 Husqvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant.

GENERAL SAFETY PRECAUTIONS Important Personal protective equipment IMPORTANT! IMPORTANT! The machine is only designed for trimming grass. A clearing saw, brushcutter or trimmer can be dangerous if used incorrectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operator’s manual.
GENERAL SAFETY PRECAUTIONS BOOTS Wear sturdy, non-slip boots. original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting. A B CLOTHING Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches. Always wear heavy, long pants. Do not wear jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level.
GENERAL SAFETY PRECAUTIONS Stop switch Use the stop switch to switch off the engine. Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. See instructions under the heading Cutting equipment. The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit. Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
GENERAL SAFETY PRECAUTIONS Never use a machine that has a faulty muffler. • Extend the life of cutting equipment. IMPORTANT! Only use cutting attachments with the guards we recommend! See the chapter on Technical data. Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter. Regularly check that the muffler is securely attached to the machine.
ASSEMBLY Fitting the loop handle • • Before using the unit, tighten the knob securely. Clip the loop handle onto the shaft. Note that the loop handle must be fitted between the arrows on the shaft. Dismantling: • Slide the spacer into the slot in the loop handle. Fit the nut, knob and screw. Do not overtighten. • Now adjust the trimmer to give a comfortable working position. Tighten the bolt/knob. • Loosen the coupling by turning the knob (at least 3 times). • Push and hold the button (C).
ASSEMBLY Assembling the cutting equipment • Screw on the trimmer head/plastic blades (H) in the opposite direction to the direction of rotation. H ! ! WARNING! When fitting the cutting attachment it is extremely important that the raised section on the drive disc/support flange engages correctly in the centre hole of the cutting attachment. If the cutting attachment is fitted incorrectly it can result in serious and/or fatal personal injury.
FUEL HANDLING Fuel safety Petrol Never start the machine: 1 If you have spilt fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilt 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 Fuelling Mixing • Always mix the petrol and oil in a clean container intended for fuel. • Always start by filling 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. • ! 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 • • 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. Starting and stopping ! WARNING! The complete clutch cover and shaft must be fitted before the machine is started, otherwise the clutch can come loose and cause personal injury. Always move the machine away from the refuelling area before starting. Place the machine on a flat surface.
STARTING AND STOPPING apply full throttle; the throttle will automatically disengage from the start setting. 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. 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 damaged spark plug cap.
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 Basic working techniques Cutting 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. • The trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.
MAINTENANCE Carburettor 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 Low speed jet L High speed jet H Try to find the highest idle speed by turning the low speed jet L clockwise then anti-clockwise. When the highest speed has been found, turn the low speed jet L 1/4 turn anti-clockwise. The high speed jet H affects the engine power, speed, temperature and fuel consumption. If the high speed jet H is set too lean (screwed in too far) the engine speed will be too high and cause engine damage. Do not let the engine run at full speed for more than 10 seconds.
MAINTENANCE Muffler Cooling system CAUTION! Some mufflers are fitted with a catalytic converter. See chapter on Technical data to see whether your machine is fitted with a catalytic converter. To keep the working temperature as low as possible the machine is equipped with a cooling system. 4 The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator.
MAINTENANCE 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 0.5 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. Check that the spark plug is fitted with a suppressor.
MAINTENANCE Bevel gear The bevel gear is filled with the right quantity of grease at the factory. However, before 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 normally need to be changed except if repairs are carried out.
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 Operator’s Manual. More extensive work must be carried out by an authorised service workshop. Maintenance Daily maintenance Clean the outside of the machine.
