CARBURETOR ANTI-FREEZE MECHANISM
See Figures 65 - 66.
The chain saw is designed with a ventilation hatch on the
right side of the cylinder cover which allows warm air to be
supplied from the engine to the carburetor to help prevent
icing under colder operating conditions. Operating the
chain saw in temperatures from 32ºF to 41ºF (0ºC to 5ºC)
at times of high humidity may result in ice forming within the
carburetor. This can cause the output power of the engine
to be reduced and/or the engine to fail to operate smoothly.
When operating under these circumstances, the chain saw
should be placed in anti-freeze mode before use.
To switch to anti-freeze mode:

Place the ignition switch in the OFF ( )position.
 Remove the air cleaner cover.
 Remove the air cleaner.
 Lift choke knob up to remove from the cylinder cover.
 Loosen the five screws holding the cylinder cover in place.
Remove the cylinder cover.
 Remove the icing cap located on the right-hand side of the
cylinder cover by pressing down on it with your finger.
 Adjust the icing cap so that the “snow” mark faces
upward, then return it to its original position in the cylinder
cover.
 Replace the cylinder cover and reinstall screws to
secure.
 Replace choke knob, air cleaner, and air cleaner cover.
WARNING
Always return the unit to normal operating mode if there
is no danger of icing occurring. Continuing to use the
chain saw in anti-freeze mode when temperatures have
risen and returned to normal may result in the engine
failing to start properly or in the engine failing to operate
at its normal speed.
CLEANING THE ENGINE
See Figures 67 - 68.
Clean the cylinder fins and flywheel fins with compressed air
or a brush periodically. Dangerous overheating of the engine
may occur due to impurities on the cylinder.
WARNING
Never run the saw without all the parts, including the
drivecase 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.

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.
