Checking the safety chain brake

Do not work with the saw without rst 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 rmly 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

immediately.

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 DOLMAR 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 lter clean, and the chain

properly tensioned. Have carburetor adjustment done by

an authorised DOLMAR service center.

Never make any changes or adjustments to the basic set-

tings 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 carbu-

retor.

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 DOLMAR service center.
