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, 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 BOOTS Throttle lockout Wear boots with steel toe-caps and non-slip sole. The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This movement is controlled by two independent return springs.
GENERAL SAFETY PRECAUTIONS be checked. See instructions under the heading Maintenance. Vibration damping system Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier. 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.
GENERAL SAFETY PRECAUTIONS cutter. Certain harnesses also have a quick release fitted to the support hook. Regularly check that the muffler is securely attached to the machine. Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly. If the muffler on your machine is fitted with a spark arrestor mesh this must be cleaned regularly.
GENERAL SAFETY PRECAUTIONS should operate the socket spanner when loosening or tightening the nut. Cutting equipment Saw blades are intended for cutting fibrous types of wood. Grass blades and grass cutters are intended for cutting coarse grass. The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.
GENERAL SAFETY PRECAUTIONS Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced. A correctly sharpened blade is essential for working efficiently and to avoid unnecessary wear to the blade and brush cutter. 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. • Sharpen all edges equally to maintain the balance of the blade.
GENERAL SAFETY PRECAUTIONS 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 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. Only use the recommended cutting attachment. See the chapter on Technical data.
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). • Align the screw hole in the throttle handle with the hole in the handlebar. • Refit the screw in the hole in the rear of the throttle handle. • Screw the screw through the handle and handlebar. Tighten it. • Remove the mounting components from the handlebar mounting. • Position the handlebar as shown.
ASSEMBLY Assembling the cutting equipment ! ! 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. • Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing.
ASSEMBLY where you should operate the socket spanner when loosening or tightening the nut. CAUTION! Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data. G F D Fitting the trimmer guard and trimmer head Trimmy SII B • 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).
ASSEMBLY Fitting other guards and cutting attachments • Fit the trimmer guard/combination guard (A) intended for use with the trimmer head/plastic blades. CAUTION! Ensure that the guard extension is fitted. 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.
ASSEMBLY Correct height 1 Forestry clearing Adjust the support strap so that the support hook is around 10 cm below your hip. The blade should be angled forward a little. 2 Grass clearing The support hook should hang around 20 cm below your hip so that the blade is parallel to the ground. Correct balance 1 Forestry clearing Move the suspension ring on the machine forward or backward. It is easier to avoid sawing into the ground if the blade is balanced a few dm above the ground.
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. you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord. Repeat pulling the cord until the engine starts. When the engine starts. return choke control to run position and apply full throttle; the throttle will automatically disengage from the start setting. Warm engine Ignition: Set the stop switch to the start position.
WORKING TECHNIQUES General working instructions yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury. IMPORTANT! This section describes the basic safety precautions for working with brush cutters 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.
WORKING TECHNIQUES • Control the felling direction (take advantage of the wind). ! Working methods ! WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury. Stop the engine and cutting equipment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury.
WORKING TECHNIQUES 3 o’clock and 5 o’clock so that the direction of rotation of the blade pushes the bottom of the tree to the left. conditions, so that cleared stems fall in the cleared area of the stand. • 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.
WORKING TECHNIQUES Brush cutting with a saw blade • Thin stems and brush are mown down. Work with a sawing movement, swinging sideways. • Try to cut several stems in a single sawing movement. • With groups of hardwood stems, first clear around the group. Start by cutting the stems high up around the outside of the group to avoid jamming. Then cut the stems to the required height. Now try to reach in with the blade and cut from the centre of the group.
WORKING TECHNIQUES • When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head. 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.
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 2 Press the start throttle lock as described under the heading Starting and stopping. 3 If the start throttle speed is too low (below 4000 rpm), turn the adjuster screw A clockwise until the cutting attachment starts to rotate. Then turn A clockwise a further 1/2 turn. CAUTION! Never use a machine with a defective muffler. ! 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.
MAINTENANCE The grease in the bevel gear does not normally need to be changed except if repairs are carried out. use common engine oil. This would drain through the filter quite quickly and collect in the bottom. Air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts. • Excessive fuel consumption.
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.
