Electric Handle Heating - Stihl MS 441 Instruction Manual

The carburetor is now heated via the
preheating plate – this helps avoid icing
up.
: At temperatures above +20°C:
Always return the shutter to the
summer position (s).
This is essential to avoid engine
running problems from overheating.
At temperatures below -10 °C
It is advisable to use the cover plate
mounting kit (special accessory) in
extremely cold conditions (temperatures
below -10°C, in powder or drifting snow).
The cover plate partially blanks off the
slots in the fan cover to help prevent
snow being sucked into the machine.
If engine idle speed is erratic or
acceleration is poor
: Turn low speed screw (L) 1/4 turn
counterclockwise.
It is usually necessary to change the
setting of the idle speed screw (LA)
after making adjustments to the the low
speed screw (L) – see "Adjusting the
Carburetor".
