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
N Remove the screw (3) from the 
shutter.
N Pull the shutter (2) out of the shroud.
N Rotate the shutter (2) from the 
summer position to the winter 
position and refit it.
N Secure the shutter in position with 
the screw (3). 
At temperatures between +10°C and 
+20°C

in this temperature range with the 
shutter (2) in the summer position.

necessary.
At temperatures above +20°C
N Always return the shutter (2) to the 
summer position.
Do not operate the machine in the winter 
position at temperatures above +20°C

engine running problems and 
overheating.
