To mount the attachment to a power unit, follow the steps below.

1. Make sure that the lock lever (A) is not tightened.

2. Align the pin (B) with the arrow mark (C).

3. Insert the shaft into the drive shaft of the power unit until the

release button (D) pops up.

4. Tighten the lock lever (A) rmly as shown.

To remove the attachment, loosen the lock lever, press the lock

button and withdraw the shaft.

Assembling saw chain and guide bar

CAUTION: Make sure that the saw chain, guide bar and

sprocket match each other in gauge and pitch.

Assemble the saw chain and guide bar as the following steps.

(Fig. 7- 9)

1. Loosen the nut (A) and remove the bar holder (B).

2. Turn the tension screw (C) counterclockwise until the tensioning

nut (D) touches the left end.

NOTICE: Do not turn the tension screw counterclockwise too much,

otherwise the tension screw and the tensioning nut comes off from

the housing.

3. Fit the saw chain (E) into the groove of guide bar (F). Start the

procedure from the bar nose.

4. Align the position bolt (G) with the notch of the guide bar (H),

and then t the saw chain (E) onto the sprocket (I). Make sure

that the saw chain is kept tting along the guide bar during the

procedure.

5. Install the guide bar (F) so that the tensioning nut (D) ts into the

hole (J) on the guide bar. Holes (K) are not used.

6. Place the saw chain onto the groove of the guide bar properly.

If the saw chain is not placed into the groove of the guide bar

properly at this point, adjust and t it appropriately.

7. Fit the bar holder (B) and tighten the nut (A) securely. Then

loose the nut a half turn as a provision of the chain tension

adjustment.

8. Adjust the chain tension. Refer to the section “Adjusting the

chain tension.”

CAUTION:

Keep the applicable chain tension. Loose tension can cause the •

saw chain derail. (Fig. 10)

To remove the saw chain and guide bar, turn the tension screw (C)

counterclockwise rst.

Pull the saw chain outward to let the saw chain comes out from

the groove of the guide bar, then remove them from the housing.

(Fig. 11)

Adjusting the chain tension

WARNING:

Before check or adjust the chain tension, switch off the motor and •

remove the spark plug cap or the battery cartridge.

Before check or adjust the chain tension, wear protective gloves.•

CAUTION:

Keep the applicable chain tension. Loose tension can cause the •

saw chain to come off during operation. Too tight tension can

damage the saw chain or guide bar.

During operation, check the chain tension frequently. The saw •

chain stretches and becomes loose during operation. When use

a new saw chain, adjust the tension more frequently. (Fig. 12)

Adjust the chain tension as the following steps.

1. Loose the nut (A) a half turn.

2. Hold the bar nose up. Turn the tensioning screw (B) clockwise

until the saw chain ts the underside of the guide bar snugly.

3. Pull the saw chain along the guide bar by hand. If it is hard to

move, turn the tensioning screw counterclockwise slightly and do

the step 2 again.

4. Tighten the nut (A) securely.

Filling the chain oil tank

The saw chain must be lubricated with chain oil during operation.

Before operation, ll the chain oil tank. After supplying the oil,

tighten the oil cap securely.

Use Makita genuine chain oil only.

NOTICE: Never use waste oil. It may damage the oil pump.

During operation, always pay attention to the oil level. Rell the

tank if the oil level becomes low. The tank becomes empty in

approximately 40 minutes of operation (depending on the setting of

the chain lubrication).

Adjusting the chain-oil feeding rate (Fig. 13 & 14)

The chain-oil feeding rate is adjustable in three steps. According

to the operation, for example cutting hard limbs, adjust the feeding

rate.

To adjust the chain-oil feeding rate, use a at-bladed screwdriver.

Push in the adjusting screw and turn it. To increase feeding rate,

turn the adjusting screw counterclockwise (A). To reduce feeding

rate, turn it clockwise (B).

After adjusting the chain-oil feeding rate, check the feeding rate by

driving the equipment at medium speed.
