GENERAL SAFETY PRECAUTIONS Important 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.
GENERAL SAFETY PRECAUTIONS BOOTS Wear boots with steel toe-caps and non-slip sole. 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.

GENERAL SAFETY PRECAUTIONS cutter. Certain harnesses also have a quick release fitted to the support hook. 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 The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.
GENERAL SAFETY PRECAUTIONS should operate the socket spanner when loosening or tightening the nut. 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.
A correctly sharpened blade is essential for working efficiently and to avoid unnecessary wear to the blade and brush cutter. • Make sure that the blade is well supported when you file it. Use a 5.5 mm round file with a file holder.
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.
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.
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.
CAUTION! Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data. • 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.
Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across both shoulders. WARNING! When using a brush cutter it must always be hooked securely to the harness. Otherwise you will be unable to control the brush cutter safely and this can result in injury to yourself or others.

When working at continuous high revs a higher octane rating is recommended. Two-stroke oil • For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two-stroke engines. • Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).
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.
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.

General working instructions 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.

• 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.

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.
See instructions under the heading Oiling the air filter. Oiling the air filter 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.
