Husqvarna 455 Rancher Operation Manual - Page 33

MAINTENANCE Make sure the vibration damping units are securely attached to the engine unit and handle unit. Never use a muffler if the spark arrestor mesh is missing or defective. Stop switch Start the engine and make sure the engine stops when you move the stop switch to the stop setting. Muffler Never use a machine that has a faulty muffler. 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. Regularly check that the muffler is securely attached to the machine. • 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. 1 2 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. English - 33
