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 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. Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination. Wear personal protective equipment. See instructions under the heading Personal protective equipment.
GENERAL SAFETY PRECAUTIONS 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. Make sure the throttle control is locked at the idle setting when the throttle lockout is released. FIRST AID KIT Always have a first aid kit nearby.
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. Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.
GENERAL SAFETY PRECAUTIONS Never use a machine that has a faulty muffler. Locking nut A locking nut is used to secure some types of cutting attachment. Regularly check that the muffler is securely attached to the machine. When fitting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.) Tighten the nut using the socket spanner.
GENERAL SAFETY PRECAUTIONS ! ! WARNING! Always stop the engine 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 HT lead from the spark plug before you start to work on it. Sharpening grass cutters and grass blades • See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single-cut flat file.
ASSEMBLY Fitting the J-handle • Clip the loop handle onto the shaft. Note that the loop handle must be fitted between the arrows on the shaft. • Slide the spacer into the slot in the loop handle. • Fit the nut, knob and screw. Do not overtighten. • Attach the J-handle to the loop handle using the three screws, as shown.
ASSEMBLY Fitting a blade guard, grass blade and grass cutter Fitting other guards and cutting attachments • G F E Hang the trimmer guard/combination guard (A) on the two hooks on the plate holder (M). Bend the guard around the shaft and tighten it with the bolt (L) on the opposite side of the shaft. Use the locking pin (C). Place the locking pin in the groove on the screw head and tighten. See diagram.
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 • trimmer guard if they have been exposed to impact or are cracked. Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found. • Never use the machine without a guard nor with a defective guard.
STARTING AND STOPPING Primer bulb: Press the air purge repeatedly until fuel begins to fill the bulb. The bulb need not be completely filled. Stopping Stop the engine by switching off the ignition. ! 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. Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot!).
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 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. 9 Never put the machine down with the engine running unless you have it in clear sight.
WORKING TECHNIQUES Basic working techniques • 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. Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground. • Reduce the risk of material wrapping around the blade by following these instructions: 1Always work at full throttle.
WORKING TECHNIQUES Cutting • 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. • Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.
MAINTENANCE Carburettor be finely adjusted. Fine adjustment should be carried out by a skilled technician. 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.
MAINTENANCE Fine adjustment of the idle speed T 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. The idle speed should also be well below the speed at which the cutting attachment starts to rotate. to run unevenly.
MAINTENANCE 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. CAUTION! Never use a machine with a defective muffler. ! 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.
MAINTENANCE Oiling the air filter Always use special filter oil. Filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. Put the filter in a plastic bag and pour the filter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil.
