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, grass clearing and/or forestry clearing. 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 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. 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.
GENERAL SAFETY PRECAUTIONS Cutting equipment General rules 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. Only use cutting attachments with the guards we recommend! See the chapter on Technical data. IMPORTANT! Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
GENERAL SAFETY PRECAUTIONS Sharpening the saw blade Trimmer head IMPORTANT! • A correctly sharpened blade is essential for working efficiently and to avoid unnecessary wear to the blade and clearing saw. • • Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. See the cutting attachment packaging for correct sharpening instructions. • Only use the recommended trimmer heads and trimmer cords.
ASSEMBLY Fitting the handlebar • Remove the screw at the rear of the throttle handle. • Slide the throttle handle onto the right side of the handlebar, (see diagram). Transport position, handlebar • The handlebar can easily be turned to fit along the shaft for easier transportation and storage. • Loosen the knob. Turn the handlebar clockwise so that the throttle handle rests against the engine. • Now twist the handlebar around the shaft. Tighten the knob.
ASSEMBLY Fitting a blade guard, grass blade and grass cutter Fitting the blade guard and saw blade G K F J E D H I A A B C L • • Remove the mounting plate (H). Fit the adapter (I) and bracket (J) with the two screws (K) as shown. Fit the blade guard (A) to the adapter using the 4 screws (L) as shown. CAUTION! Use the recommended blade guard. See the Technical data section. Hook the blade guard/combination guard (A) onto the fitting on the shaft and secure with the bolt.
ASSEMBLY arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut. Fitting a trimmer guard and Superauto II 1” trimmer head • 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. • To dismantle, follow the instructions in the reverse order.
ASSEMBLY Adjusting the harness and clearing saw ! WARNING! When using a clearing saw it must always be hooked securely to the harness. Otherwise you will be unable to control the clearing saw safely and this can result in injury to yourself or others. Never use a harness with a defective quick release. Correct balance Let the cutting attachment rest lightly on the ground. If you use a saw blade it should balance about 10 cm above the ground to prevent contact with stones and the like.
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. Stopping Stop the engine by switching off the ignition. 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 Keep a good balance and a firm foothold. 7 Always hold the machine with both hands. Hold the machine on the right side of your body. 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.
WORKING TECHNIQUES ! WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning. • You should plan the strip so that you avoid going over ditches or other obstacles on the ground. You should also orient the strip to take advantage of wind conditions, so that cleared stems fall in the cleared area of the stand.
WORKING TECHNIQUES • To fell a tree forwards, the bottom of the tree should be pulled backwards. Pull the blade backwards with a quick, firm movement. • Large stems must be cut from two sides. First determine which direction the stem will fall. Make the first cut on the felling side. Then finish cutting the stem from the other side. Adjust the cutting pressure to match the size of the stem and the hardness of the wood. Small stems require more pressure, while large stems require less pressure.
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 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 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 Air filter Spark plug The air filter must be regularly cleaned to remove dust and dirt in order to avoid: The spark plug condition is influenced by: • Incorrect carburettor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). Loss of engine power • A dirty air filter. • Unnecessary wear to engine parts. • Excessive fuel consumption. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.
