At temperatures below -14 °F:
It is advisable to fit the optional cover
plate* on the fan housing in extremely
cold conditions (temperatures below
-14 °F, in powder or drifting snow).
The cover plate blanks off the lower slots
in the fan housing to help prevent snow
being sucked into the machine.
When the cover plate is fitted, the
shutter in the carburetor box cover must
be in the winter position.
: If your saw is very cold (frost or ice
on machine), start the engine and
keep it at a high idle speed (with
chain brake disengaged) until it
reaches normal operating
temperature.
: In the event of engine running
problems, first check that conditions
for use of intake air preheating still
apply.
