Dolmar PS6400CH Manuale Utente

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!
