18 Winter Operation
18.1 At temperatures below +10°C
Preheating the carburetor
Repositioning a shutter allows heated air to be
drawn in from around the cylinder and mixed with
cold air – this helps prevent carburetor icing.
An arrow (1) on the shroud indicates the setting
of the shutter (2) for summer or winter operation.
Meaning of symbols:
–
"Sun" = summer operation
–
"Snowflake" = winter operation
► Remove the screw (3) from the shutter.
► Pull the shutter (2) out of the shroud.
► Rotate the shutter (2) from the summer posi‐
tion to the winter position and refit it.
► Secure the shutter in position with the
screw (3).
18.2 At temperatures between
+10°C and +20°C
The machine can normally be operated in this
temperature range with the shutter (2) in the
summer position. Change the position of the
shutter if necessary.
18.3 At temperatures above +20°C
► Always return the shutter (2) to the summer
position.
NOTICE
Do not operate the machine in the winter position
at temperatures above +20°C because there is
otherwise a risk of engine running problems and
overheating.
