Unit/Maintenance Safety
Disconnect the spark plug before perform- ing maintenance, except carburetor adjust- ments.
Muffler
CAUTION! Muffler is fitted with a catalytic converter designed to reduce harmful ex- haust gases.
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 com- bustible material.
Mufflers are equipped with a special spark arrestor mesh. The mesh should be checked and, if necessary. cleaned by a servicing dealer. If the mesh is damaged, it should be replaced. If the mesh is fre- quently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your servicing dealer to inspect the muffler. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston.
