Chain Saw Owner's Manual

5. Spark arrester

The muffler is equipped with a spark arrester to

prevent red hot carbon from flying out of the exhaust

outlet. Periodically check and clean as necessary with

a wire brush after removing two muffler cover nuts and

one screw.

(1) Spark arrester

Never use a muffler if the spark arrester is missing or

defective.

6. Exhaust port

Remove the muffler, insert a screwdriver into the vent,

and wipe away any carbon buildup after every 100

hours of use. Wipe away any carbon buildup on the

muffler exhaust vent and the cylinder exhaust port at

the same time.

(1) Muffler exhaust vent

(2) Cylinder exhaust port

7. Sprocket

Check for cracks and for excessive wear interfering

with the chain drive. If the wear is considerable,

replace it with new one. Never fit a new chain on a

worn sprocket, or a worn chain on a new sprocket.
