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

(only an authorized service center)

CAUTION:

Optimum perfornance can only be achieved if the car- buretor is adjusted correctly. For this work, which should be carried out only by an expert, the engine must be warmed up and the air filter must be clean.

The carburetor has been adjusted by MAKITA on the basis of atmosheric pressure conditions at sea level. Other atmospher- ic pressure conditions or the running-in process of a new engine may require readjustment of the carburetor.

Set idle speed

Adjust the idle speed using a screwdriver (8), blade width 0.16" (4 mm).

If the chain turns when the engine is idling, unscrew the throttle-valve stop screw (9) until the chain stops. If the engine runs unevenly, screw the screw (9) in.
