At temperatures below + 50 °F
(+10 °C), preheat carburetor as
follows:
: Remove the carburetor box cover.
Inside the carburetor box cover:
: Move the shutter from summer
position (1) to winter position (2).
Heated air is now drawn in from around
the cylinder and mixed with cold air –
this helps prevent carburetror icing.
: At temperatures above + 68 °F
(+20 °C):
Return shutter to summer position.
This is essential to avoid engine
running problems and overheating.
Machines with HD filter:
: Install a standard filter in place of
the HD-Filter.
: Refit the carburetor box cover and
tighten down the twist lock.
Rescue Saw
At temperatures below + 14 °F
(-10 °C):
It is advisable to fit the optional cover
plate (1128 080 7500) on the fan
housing in extremely cold conditions
(temperatures below + 14 °F (-10 °C), in
powder or drifting snow).
The cover plate blocks 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.
