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 screen. If your machine has this type of muffler, you should clean the screen at least once a week. This is best done with a wire brush. A blocked screen will cause the engine to overheat and may lead to serious damage.
Note! The screen must be replaced if it is damaged. If the screen 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 screen 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.
Replacing the starter cord
•Loosen the screws that hold the starter against the crankcase and remove the starter.
• Pull out the cord approx. 30 cm (12 inches) and hook it into the notch in the rim of the pulley. Release the recoil spring by letting the pulley rotate slowly backwards.
