15 Winter Operation
15.1 Remove shroud
► Move the Master Control lever to the stop
position 0
► Push the hand guard forwards – the saw chain
is blocked
► Loosen screws (1)
► Remove the shroud (2)
15.2 Pre-heat carburetor
15.2.1 At temperatures below +10 °C
►
Pull the slide (1) out of the position s (sum‐
mer operation)
►
Place the slide in the position r (winter oper‐
ation) – r facing upwards
► Refit the shroud and tighten the screws
Heated air is now drawn in from around the cylin‐
der and circulates around the carburetor – this
helps prevent carburetor icing.
15.2.2 At temperatures above +20 °C
►
Ensure that the slide is set back to position s
(summer operation) without fail, otherwise the
engine may malfunction due to overheating
15.3 At temperatures below -10 °C
Under extreme winter conditions (temperatures
below -10 °C, powdered or drifting snow), it is
recommended to use the "cover plate mounting
kit" (special accessory).
In case of erratic idling behavior or poor acceler‐
ation
► Turn the low speed screw (L) 1/4 turn counter‐
clockwise
Whenever the low speed screw (L) has been
adjusted, it is usually also necessary to adjust
the idle speed adjusting screw (LA), see "Setting
the carburetor".
► if the chain saw is extremely cold (frost forma‐
tion) – after starting, bring the engine up to
operating temperature at increased idle speed
(disengage chain brake!)
15.4 Cover plate
The cover plate (special accessory) keeps out
powdered or drifting snow.
When the cover plate is used, the slide must be
in the winter position.
If engine trouble occurs, first check whether use
of the cover plate is necessary.
15.4.1 Attach cover plate
► Insert cover plate (1) with both tabs (arrows)
and fasten with the screws (2)
