MAINTENANCE

Muffler

Never use a machine that has a faulty muffler.

Regularly check that the muffler is securely attached to the machine.

Some mufflers are equipped with a special spark arrestor mesh. If your machine has this type of muffler, you should clean the mesh at least once a week. This is best done with a wire brush. A blocked mesh will cause the engine to overheat and may lead to serious damage.

Note! The mesh must be replaced if it is damaged. If the mesh is blocked the machine will overheat and this will cause damage to the cylinder and piston. Never use a machine with a muffler that is in poor condition.

Never use a muffler if the spark arrestor mesh is missing or defective.

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 combustible material.

Starter

WARNING! When the recoil spring is wound

!up in the starter housing it is under tension and can, if handled carelessly, pop out and cause personal injury.

Care must be exercised when replacing the return spring or the starter cord. Wear protective glasses and protective gloves.

Changing a broken or worn starter cord

Loosen the screws that hold the starter against the crankcase and remove the starter.

• Pull out the cord approx. 30 cm and hook it into the notch in the rim of the pulley. Release the recoil spring by letting the pulley rotate slowly backwards.

Undo the screw in the centre of the pulley and remove the pulley. Insert and fasten a new starter cord to the pulley. Wind approx. 3 turns of the starter cord onto the pulley.

Connect the pulley to the recoil spring so that the end of the spring engages in the pulley. Fit the screw in the centre of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord.
