Adjusting The Carburetor - Dolmar PS-32 C Manual De Instrucciones

Adjusting the carburetor

CAUTION: Carburetor adjustment may only be done by
a specialist DOLMAR service center!
SERVICE
Do not undertake any adjustments to adjusting screws
(H) and (L) without a tachometer! Incorrect adjustment
can lead to engine damage!
A tachometer is needed for adjustments to adjusting
screws (H) and (L), because if the engine runs over its
maximum rated speed, it can overheat and run out of
lubricant. This can damage the engine!
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 as-
sembly and testing of the saw!
Idle speed adjustment must only be undertaken when
the engine is warm, with a clean air filter and properly
installed guide bar and chain.
Use a screwdriver (5/32" (4 mm) blade) for idle 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!
Note:
Carburetor adjustment aids in proper functioning, eco-
nomical consumption, and safe operation.
Because of new exhaust regulations, the carburetor adjust-
ing screw (H) now comes with a limit feature. The reduced
adjustment range (about 180 degrees) prevents excessive-
ly rich carburetor settings. On some models, the adjusting
screw (H) is locked. This ensures compliance with exhaust
regulations, as well as good engine functioning and eco-
nomical fuel consumption.
