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.

STARTING AND STOPPING Check before starting • Never use the machine without a guard nor with a defective guard. • All covers must be correctly fitted and undamaged before you start the machine. • 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.
STARTING AND STOPPING Primer bulb: Press the air purge repeatedly until fuel begins to fill the bulb. The bulb need not be completely filled. shock if the spark plug cap has been damaged.

WORKING TECHNIQUES General working instructions 6 Always hold the machine with both hands. Hold the machine on the right side of your body. 7 Keep the cutting attachment below waist level. 8 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. 9 Never put the machine down with the engine running unless you have it in clear sight.
WORKING TECHNIQUES Basic working techniques • Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage. Try to work rhythmically. Stand firmly with your feet apart. Move forward after the return stroke and stand firmly again. • Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.
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 Carburettor Adjusting the idle speed (T) Check that the air filter is clean. When the idle speed is correct, the cutting attachment should not rotate. If adjustment is required, close (turn clockwise) the idle adjustment screw T, with the engine running, until the cutting attachment starts to rotate. Open (turn anticlockwise) the screw until the cutting attachment stops.
MAINTENANCE Air filter Bevel gear The air filter must be regularly cleaned to remove dust and dirt in order to avoid: 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. • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts. • Excessive fuel consumption.
