Checking the chain brake

Do not work with the chain saw without first checking the chain brake!

Start the engine as described (make sure you have a good footing, and place the chain saw on the ground in such a way that the guide bar 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 (L/6) 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 in this test, do not under any circumstances proceed with work. Contact a MAKITA service center for repair.

Adjusting the carburetor

Important information:

The carburetor of this tool is fitted with limiter caps which restrict the range of adjustment and prevents over-rich mixture settings. This ensures providing good engine power and efficient fuel consumption.

Before installing the limiter caps, the manufacturer performs the „Basic Adjustment” procedure.

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

It is urgently recommended to use a revolution indicator (8) (accessorie, not delivered with the chain saw) in order to achieve a correct adjustment of the carburetor. Adjust the carburetor using a 0.16" (4 mm) screwdriver.

The screwdriver shown (7) (accessorie, not delivered with the chain saw) has a molded-on lug to assist in adjustment.

Before adjusting the carburetor the engine must be warmed up for a period of 3-5 min.

Adjustment instructions (step 1) STOP

For adjusting the carburetor correctly the following steps must be carried out:

1. Check adjustment

 

STOP

 

2.Start engine

3.Set idle speed

4.Adjust speed

5.Check idling speed

6.Check acceleration

7.Check max. speed or output

8.Repeat adjustment procedure starting with step 3, until idling speed, max. speed and acceleration are reached with the adjustment made.

Before initial operation make sure that the adjusting screws (9 and 10) have not been set in all the way. Limiter caps do not protect the engine from leaning.

Turn the two adjusting screws (9 and 10) counter-clock- wise as far as they will go.

Start the engine and let it warm up (step 2).

Set idle speed (step 3)

If the chain turns when the engine is idling, unscrew the throttle-valve stop screw (11) until the chain stops. If the engine runs unevenly, screw the screw (11) back in.

Idling speed should be 2,800 rpm.
