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 Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant.

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. This arrangement means that the throttle control is automatically locked at the idle setting. A B CLOTHING Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches.
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 reduce 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 saw. 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 screen 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 clearing saw. 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.

FUEL HANDLING Fuel safety Gasoline Never start the machine: 1 If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilled 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 Fueling Mixing • Always mix the gasoline and oil in a clean container intended for fuel. • Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline. • ! 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. handle, slowly pull out the cord with your right hand until 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.
WORKING TECHNIQUES General working instructions position 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 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.
WORKING TECHNIQUES 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).
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 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 Carburetor 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 Low speed jet L High speed jet H Try to find the highest idling speed, turning the low speed needle L clockwise respectively counter-clockwise. When the highest speed has been found, turn the low speed needle L 1/4 turn counter-clockwise. 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.
MAINTENANCE Adjusting the start throttle speed The correct start throttle speed is set by means of an adjuster on the rear of the handle next to the cable. Use this screw (4 mm Allen screw) to increase or decrease the start throttle speed. 4 mm Proceed as follows: 1 Run the machine at idle. 2 Press the start throttle lock as described under the heading Starting and stopping.
MAINTENANCE 4 Cylinder cover (directs cold air over the cylinder). Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder. Bevel gear The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled three-quarters full with grease. Use HUSQVARNA special grease.
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 manual. More extensive work must be carried out by an authorised service workshop.
