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.

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.
