WARNING!
Do not touch the silencer until it
has cooled down, otherwise you
may burn yourself.
Repair instructions
Remove the chain catcher and replace it with a
new one. Check that the vibration damping spring
locates correctly against the crankcase when you
bolt the new chain catcher in position.
A worn (damaged) chain catcher on 340, 345 or
350 can be replaced with the same chain catcher
as 346XP, 351 and 353 (see figure above).
3
Turn the chain tensioner anticlockwise as far as it
will go.
Refit:
• guide bar
• chain
• clutch cover
Silencer – removal
Remove the cylinder cover, silencer support,
silencer, gasket and cooling plate.

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.
