Safety equipment
WARNING!
Do not touch the silencer until it
has cooled down, otherwise you
may burn yourself.
6.3 Silencer – removal
1
Remove the cylinder cover, silencer, gasket and
cooling plate.
2
If the saw is fitted with a spark arrestor mesh (A) this
must also be removed. If necessary, use the com-
bination spanner to push down the plate edge and
remove the spark arrestor mesh (see figure 11).
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.
6.4 Silencer – refitting
1
If the saw is equipped with a spark arrestor mesh
this should be fitted first. When fitting the mesh,
make sure that the mesh is inserted in the right
position. If necessary, use the combination spanner
to insert the mesh.
2
Refit
• cooling plate
• gasket
• silencer, tighten bolts to a torque of 8–10 Nm.
• cylinder cover
3
Run the saw for at least 1 minute, then retighten the
silencer bolts to 12–14 Nm.
