SAFETY INSTRUCTIONS Personal protective equipment IMPORTANT! Whenever you use a clearing saw, brushcutter or trimmer you must wear personal protective equipment that is approved by the authorities. Personal protective equipment does not eliminate the risk of accidents, but it can reduce the effects of an injury in the event of an accident. Ask your dealer for help when choosing protective equipment. ! WARNING! Listen out for warning signals or shouts when you are wearing hearing protection.
SAFETY INSTRUCTIONS Cutting attachment guard Quick release 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. There is an easily accessible, quick release fitted at the front as a safety precaution in case the engine catches fire, or in any other situation that requires you to free yourself from the machine and harness.
SAFETY INSTRUCTIONS ! WARNING! Bear in mind that: Checking, maintaining and servicing the machine′s safety equipment Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated. IMPORTANT! All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment.
SAFETY INSTRUCTIONS • 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. Vibration damping system • Regularly check the vibration damping units for cracks or deformation.
SAFETY INSTRUCTIONS Cutting equipment Locking nut This section describes how to choose and maintain your cutting equipment in order to: • Reduce the risk of kickback. • Obtain maximum cutting performance. • Extend the life of cutting equipment. • 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.
SAFETY INSTRUCTIONS Cutting equipment Sharpening grass cutters and grass blades IMPORTANT! This section describes how to choose and maintain your cutting equipment in order to: • See the cutting attachment packaging for correct sharpening instructions. Extend the life of cutting equipment. • Sharpen blades and cutters using a single-cut flat file. Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
SAFETY INSTRUCTIONS General safety precautions Fuel safety IMPORTANT! The machine is only designed for trimming grass, grass clearing and/or forestry clearing. 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.
SAFETY INSTRUCTIONS General working instructions Adjusting the harness and clearing saw IMPORTANT! ! This section describes the basic safety precautions for working with clearing saws and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. Avoid all usage which you consider to be beyond your capability.
SAFETY INSTRUCTIONS The ABC of clearing • Always use the correct equipment. • Make sure the equipment is well adjusted. • Follow the safety precautions. • Organise your work carefully. • Always use full throttle when starting to cut with the blade. • Always use sharp blades. • Avoid stones. • Control the felling direction (take advantage of the wind). ! WARNING! Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions.
SAFETY INSTRUCTIONS • If the stems are tightly packed, adapt your walking pace to suit. • Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground. • If the blade jams in a stem, never jerk the machine free. If you do this the blade, bevel gear, shaft or handlebar may be damaged. Release the handles, grip the shaft with both hands and gently pull the machine free.
SAFETY INSTRUCTIONS 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.

Secure the trimmer guard using the 4 screws (L) and the support plate (M) as shown. • Fit the drive disc (B) on the output shaft. • Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing.
ASSEMBLY Correct height 1 3 Adjust the shoulder strap to distribute the load evenly across your shoulders. Press downwards on the suspension hook to load the harness. 4 Adjust the height of the suspension hook as described in the instructions for the standard harness. (Forestry clearing) Grass clearing 5 The machine should be supported in a harness when grass clearing so that the cutting equipment is parallel to the ground.
FUEL HANDLING Fuel Mixing CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure 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. • Always mix the gasoline and oil in a clean container intended for 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 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. Starting Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot!).
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 ! WARNING! If the idle speed cannot be adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired. High speed jet H 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 Air filter Oiling the air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid: Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts • Excessive fuel consumption.
MAINTENANCE Spark plug Filing the saw blade 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. ! WARNING! Using an incorrect cutting attachment or an incorrectly sharpened blade increases the risk of kickback.
MAINTENANCE Maintenance schedule Monthly maintenance Below you will find some general maintenance instructions. If you need further information please contact your service workshop. • Clean the fuel tank. • Clean the outside of the carburettor and the space around it. Daily maintenance • Clean the fan and the area around it. • Check fuel hose for cracks or other damage. Change if necessary. • Change the fuel filter in fuel tank. • Check the clutch, clutch springs and the clutch drum for wear.
