Checking the chain lubrication

Never work with the chain saw withoute sufficient chain lubri-

cation. Otherwise the service life of the chain and guide bar

will be reduced.

Before starting work check the oil level in the tank and the oil

feed.

Check the oil feed rate as described below:

- Start the chain saw.

- Hold the running chain saw approx. 6" (15 cm) above a

trunk or the ground (use an appropriate base).

If the lubrication is sufficient, you will see a light oil trace

because oil will be flung off the sawing device. Pay attention to

the direction the wind is blowing and avoid unnecessary

exposure to the oil spray!

Adjusting the carburetor

Adjustment instructions (step 1)

Before initial operation make sure that the adjusting screws

(H and L) have not been set in all the way. Limiter caps do not

protect the engine from leaning. Turn the two adjusting screws

(H and L) counter-clockwise 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 (S) until the chain stops. If the

engine runs unevenly, screw the screw (S) back in.

- Idling speed should be 2,400 rpm.

Adjust speed (output) (step 4)

- Adjust the speed by adjusting the main jet screw (H) to 13,000

rpm (DCS 6000i) and 12.800 rpm (DCS 6800i).

Check idle speed (step 5)

- After having adjusted the max. speed ensure the idle speed

is set to 2,400 rpm. (the chain must not turn). Use the idle

jet screw (L) to regulate it. Turn in the screw (L) to speed up,

and turn out the screw (L) to speed down the engine.

Check acceleration (step 6)

- Now check the acceleration, i. e. the time necessary for

speeding up from idle speed to max. speed. To do this,

press the throttle lever hard.

- If the acceleration is too low, turn out the idle jet screw (L)

approx. 1/8 rotation.

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.

The carburetor has been adjusted by MAKITA on the basis of

atmosheric pressure conditions at sea level. Other atmospheric

pressure conditions or the running-in process of a new engine

may require readjustment of the carburetor.

It is urgently recommended to use a revolution indicator (E/1)

(order number 950 233 210) in order to achieve a correct

adjustment of the carburetor. Adjust the carburetor using a 0.16"

(4 mm) screwdriver.

The screwdriver shown (E/2) 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.

For adjusting the carburetor correctly the following steps

must be carried out:

1. Check adjustment

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.
