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 Charles 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 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 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 lock is released. FIRST AID KIT Always have a first aid kit nearby. Press the throttle lock and make sure it returns to its original position when you release it.
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 If the muffler on your machine is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh 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.
GENERAL SAFETY PRECAUTIONS General rules Trimmer head IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. Only use cutting attachments with the guards we recommend! See the chapter on Technical data. • Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used.
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. CAUTION! Always use a quality petrol/oil mixture at least 90 octane (RON).
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 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.
STARTING AND STOPPING 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. Stopping Stop the engine by switching off the ignition.
WORKING TECHNIQUES General working instructions 6 Keep the cutting attachment below waist level. 7 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. 8 Never put the machine down with the engine running unless you have it in clear sight. IMPORTANT! This section describes the basic safety precautions for working with clearing saws and trimmers.
WORKING TECHNIQUES Grass clearing using a grass blade • Grass blades and grass cutters must not be used on woody stems. • A grass blade is used for all types of tall or coarse grass. • The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-to-right is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.
MAINTENANCE Carburettor 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 carburettor 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 Cooling system Air filter To keep the working temperature as low as possible the machine is equipped with a cooling system. The air filter must be regularly cleaned to remove dust and dirt in order to avoid: 3 2 • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts. • Excessive fuel consumption. 1 The cooling system consists of: 1 Air intake on the starter. 2 Cooling fins on the cylinder.
MAINTENANCE Spark plug The spark plug condition is influenced by: • Incorrect carburettor 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 Operator’s Manual. More extensive work must be carried out by an authorised service workshop. Maintenance Daily maintenance Clean the outside of the machine.
