Checking The Safety Chain Brake; Set Idle Speed - Dolmar DCS34 Owner's And Safety Manual

Checking the safety chain brake

Do not work with the saw without first checking the chain
brake!
Start the engine as described (make sure you have a
good footing, and place the saw on the ground in such a way
that the blade is free of contact).
Grasp the tubular handle firmly with one hand and hold
the rear handle with the other.
With the engine running at moderate speed, press the hand
guard (7) in the direction of the arrow with the back of your hand
until the chain brake engages. The chain should stop immedi-
ately.
Immediately release the throttle and release the chain brake.
IMPORTANT: If the chain does not stop immediately when
you test the chain brake, do NOT use the saw! Take the
saw to a MAKITA service center for repair.
Adjusting the carburetor
Carburetor adjustment is necessary for optimum engine
performance, for safer and more economical operation.
The engine should be warm, the air filter clean, and the
chain properly tensioned. Have carburetor adjustment
done by an authorised MAKITA service center.
Never make any changes or adjustments to the basic
settings for the idle nozzle (L) or main nozzle (H), as this
can cause damage to the engine!
The carburetor is factory-adjusted for the air pressure at sea
level. At other elevations or under other conditions of weather,
temperature, or humidity, or when breaking in a new engine, it
may be necessary to make slight adjustments to the carburetor.
Adjusting the idle speed
Before adjusting the carburetor, run the engine 3-5 minutes to
warm it up, but not at high speeds!
Use a screwdriver (0.16" blade) for the adjustment. The correct
size screwdriver is available as an accessory.
If the chain moves on idle although the throttle is not pressed,
the idle speed is too high and must be reduced. Screw out the
adjusting screw (9) counter-clockwise in small increments, until
the chain no longer moves.
If the engine is running unevenly (tends to go out), the idle
speed is too low and needs to be increased. Screw in the
adjusting screw (9) clockwise in small increments until the
engine runs evenly.
Important: the chain must not move in idle!
If these steps do not take care of the problem, do not use the
chainsaw! Take it to a MAKITA service center.
