Repair instructions

Silencer – removal

WARNING!

Do not touch the silencer until it has cooled down, otherwise you may burn yourself.

1

Remove the cylinder cover, silencer support, silencer, gasket and cooling plate.

2

If the saw is fitted with a spark arrestor mesh this must also be removed.

Cleaning and inspection

Clean and inspect all parts carefully. If there are any cracks or other defects replace the damaged parts with new ones.

The spark arrestor mesh is best cleaned with a wire brush. If the mesh is damaged it must be replaced.

If the mesh is blocked the saw will overheat and this will cause damage to cylinder and piston. Never use the saw with a silencer that is in poor condition. Always use original parts.

If the saw is equipped with a spark arrestor mesh this should be fitted first.
