MAINTENANCE

The owner is responsible for the perfor- mance of all required maintenance as defined in the operator’s manual.

Carburetor

Your Husqvarna product has been designed and manufactured to specifications that re- duce 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 minimize harm- ful exhaust emissions after the run--in peri- od, ask your servicing dealer to adjust your carburetor.

WARNING: The complete clutch, clutch cover, and shaft must be fitted before the machine is started, otherwise parts could come loose and cause personal injury.

Function

SThe carburetor governs the engine’s speed via the throttle control. Air and fuel

are mixed in the carburetor.

SThe T--screw regulates the throttle setting at idle speed. If the T--screw is turned clockwise this gives a higher idle speed; turning it counterclockwise gives a lower idle speed.

Basic setting

SThe basic carburetor settings are ad- justed during testing at the factory. Fine adjustment should be carried out by a skilled technician.

CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned counterclockwise until the cutting attachment stops.

Rec. idle speed:

See “Technical data” section.

Recommended max. speed:

See “Technical data” section.

Fine adjustment of the idle speed-T

Adjust the idle speed using the idle adjust- ment screw--T if it is necessary to readjust. First, turn the idle adjustment screw--T clockwise until the cutting attachment starts to rotate. Then, turn the screw counter- clockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every posi- tion. The idle speed should also be well below the speed at which the cutting attach- ment starts to rotate.

Idle Speed

Screw--T

WARNING: If the idle speed can- not be adjusted so that the cutting attachment stops, contact your ser- vicing dealer. Do not use the ma- chine until it has been correctly ad- justed or repaired.

Unit/Maintenance Safety

Disconnect the spark plug before perform- ing maintenance, except carburetor adjust- ments.

Muffler

CAUTION! Muffler is fitted with a catalytic convertic designed to reduce harmful ex- haust gases.

The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and com- bustible material.

Mufflers are equipped with a special spark arrestor mesh. You should clean the mesh at least once a month. This is best done with a wire brush. If the mesh is damaged it should be replaced. If the mesh is fre- quently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston.

CAUTION! Never use a machine that has a faulty or loose muffler. Ensure the muffler bolts are tight.
