CLEANING THE ENGINE
See Figures 65 - 68.
Clean the cylinder fins and flywheel fins with
compressed air or a brush periodically. Danger-
ous overheating of the engine may occur due to
impurities on the cylinder.
WARNING
Never run the saw without all the parts, including
the clutch cover and starter housing, securely
in place.
Because parts can fracture and pose a danger
of thrown objects, leave repairs of the flywheel
and clutch to factory trained authorized service
center personnel.
 Remove the screws and cylinder cover as
described previously.
 Clean the cylinder fins.
 Lift the chain brake over the post.
 Lay the chain saw on its side with the bar and
chain on the ground.
 Remove the chain oil and fuel caps.
 Remove the three screws that hold the starter
housing in place.
 Lift off the starter cover and set aside.
 Replace chain oil and fuel caps to prevent con-
tamination during cleaning.
 Clean the flywheel fins.
 Remove the chain oil and fuel caps.

NOTE: Check to ensure that the air filter is in the
proper position before reinstalling the cylinder
cover.
NOTE: If you notice a power loss with the gas-
powered tool, the exhaust port and muffler may
be blocked with carbon deposits. These deposits
may need to be removed to restore performance.
We highly recommend that only qualified service
technicians perform this service.
