Preheating the carburetor
N Remove the shroud – see "Shroud".
At temperatures below +50°F (+10°C)
N Use the combination wrench or a
screwdriver to ease the shutter out
of the summer position s.
N Refit the shutter the other way round
in the winter position – the arrow
points to the symbol r – the shutter
must snap into position.
The arrowhead (1) is visible in the winter
position.
N Install the shroud – see "Shroud".
Heated air is now drawn in from around
the cylinder to warm the carburetor – this
helps prevent carburetor icing.
At temperatures above +70 °F (+20 °C)
N Always return the shutter to the
summer position (s ) to avoid
engine running problems and
overheating.
At temperatures below +14 °F (-10 °C)
It is advisable to fit the "cover plate" kit
(special accessory) if you use your saw
in extremely cold conditions
(temperatures below +14 °F (-10 °C), in
powder or drifting snow).
N 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.
Cover plate
The cover plate (special accessory)
helps prevent snow being sucked into
the machine.
When the cover plate is fitted, the
shutter must be in the winter position.
In the event of engine running problems,
first check that conditions for use of the
cover plate still apply.
Fitting the cover plate
N Place the cover plate (1) in position,
engage the two tabs (arrows), and
secure it with the screws (2).
