Working in winter
In order to prevent carburetor icing in conditions of low tempe-
rature combined with high humidity, and below + 5°C in order
to get up to operating temperature faster, heated air can be
taken from the cylinder.
Remove the filter hood (see „Cleaning air filter“)
Remove the insert (10) and insert it as shown in position B for
cold-weather operation.
At temperatures above + 5°C the carburetor must NOT be fed
heated air. Failure to follow these instructions can lead to
damage to the cylinder and piston!
At temperatures over +5°C place the insert in position A for
normal operation.
Position A - Normal operation
Position B - Cold-weather operation
Reinstall the filter hood.

Adjusting the carburetor
CAUTION: Carburetor adjustment may only be done by a
specialist DOLMAR service center!
Only adjusting screw (S) can be manipulated by the user.
If the saw chain moves in idle (i.e. without the throttle being
pressed), it is imperative to correct the idle speed!
Do not adjust the idle speed until after complete assembly
and testing of the saw!
Idle speed adjustment must only be undertaken when
the engine is warm, with a clean air filter and properly in-
stalled guide bar and chain.
Use a screwdriver (5/32” (4 mm) blade) for idle speed adjust-
ments.
Adjusting the idle speed
Turn adjusting screw (S) counter-clockwise (unscrew): Idle
speed decreases.
Turn adjusting screw (S) clockwise (screw in): Idle speed
increases.
Important: If the saw chain still moves during idle even
after you have adjusted the idle speed, do NOT use the
saw. Take it to a DOLMAR service center!
