: Pry the shutter (1) out of the
carburetor box cover and slide it into
the slot (2) at the bottom end of the
carburetor box cover.
The shutter must be returned to the
"summer" position at temperatures
above +20°C. This is necessary to
avoid engine running problems and
overheating.

Fit the carburetor box cover and secure
it with the twist lock:
Preheated air from around the cylinder is
now drawn in along with cold air – this
helps prevent carburetor icing.
At temperatures below -10°C
It is advisable to fit the intake air
preheating kit* if you use your saw in
extremely cold conditions (temperatures
below -10°C, 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 shutter for carburetor preheating
must be in the "winter" position when the
intake air preheating kit is fitted.
* see "Guide to Using this Manual"
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.
