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 Wear boots with steel toe-caps and non-slip sole. 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. Always wear heavy, long pants.
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. Using incorrectly wound cord or a blunt or incorrect cutting attachment (wrong type or incorrectly filed, see instructions under the heading Filing the blade) increases the level of vibration.
GENERAL SAFETY PRECAUTIONS under the heading Adjusting the harness and brush cutter. Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly. Muffler 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 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.) Tighten the nut using the socket spanner. ! ! When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade.
GENERAL SAFETY PRECAUTIONS Keep the correct setting on the saw blade! Follow our instructions and use the recommended setting tool. An incorrectly set saw blade increases the risk of jamming and blade thrust, and damage to the saw blade. A correctly sharpened blade is essential for working efficiently and to avoid unnecessary wear to the blade and brush cutter. Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
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 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. • Fit the transport guard to the cutting attachment. • • • • • Remove the screw at the rear of the throttle handle.

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. • G Hook the blade guard/combination guard (A) onto the fitting on the shaft and secure with the bolt.
ASSEMBLY the spanner in the opposite direction to the direction of rotation (Caution! left-hand thread). • When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade. You should therefore always ensure that your hand is shielded by the blade guard when doing this. Always use a socket spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut.

B C A Spreading the load on your shoulders A • 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. • Insert the locking pin (C) in the hole to lock the shaft.
FUEL HANDLING Fuel handling Petrol Never start the machine: Always use an unleaded quality petrol of at least 90 octane (RON). 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 When the oil level is low, top up using engine oil to the edge of the oil refill hole. Only use recommended engine oil. Fuelling ! WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently.
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. O I Starting ! L Warm engine Ignition: Set the stop switch to the start position. Choke: Put the choke in working position. 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.
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). ! 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. • Start at whichever end of the area is easiest, and clear an open space from which to work. • Work systematically to and fro across the area, clearing a width of around 4-5 m on each pass.
WORKING TECHNIQUES • To fell to the left, the bottom of the tree should be pushed to the right. Tilt the blade and bring it diagonally down to the right, exerting firm pressure. At the same time push the stem using the blade guard. Cut with the area of the blade between 3 o’clock and 5 o’clock. Apply full throttle before advancing the blade. • To fell to the right, the bottom of the tree should be pushed to the left. Tilt the blade and bring it diagonally up to the right.
WORKING TECHNIQUES Grass clearing using a grass blade can also damage sensitive bark on trees and bushes, and damage fence posts. • • 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-toright is the return stroke.
MAINTENANCE Carburettor ! WARNING! The complete clutch cover and shaft must be fitted before the machine is started, otherwise the clutch can come loose and cause personal injury. Muffler 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. The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator.
MAINTENANCE Cooling system cylinder. Check that the spark plug is fitted with a suppressor. 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: • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts. • Excessive fuel consumption.
MAINTENANCE excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom. Bevel gear The bevel gear is filled with the right quantity of grease at the factory.
