Operation Manual
$WWHPSHUDWXUHVEHORZ&)
It is advisable to fit the optional intake
air preheating kit if you use your saw in
extremely cold conditions (temperatures
below -10 °C /+14 °F, in powder or
drifting snow).
When fitted, the kit ensures that only
heated air is drawn in from around the
cylinder -
it prevents air filter and carburetor icing.
The rotary shutter for carburetor
preheating must be IXOO\RSHQ
when the intake air preheating kit is fitted.
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.
The air filter may load up faster when
you use intake air preheating -
clean it more frequently.
In the event of engine running problems,
first check that conditions for use
of intake air preheating still apply.
