Start the engine and make sure the engine stops when you 
move the stop switch to the stop setting.

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.

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.
