always using a rising platform for sawing in trees. Repelling techniques are
extremely dangerous and require special training. The operator must be trained
in and familiar with the use of safety equipment and working and climbing
techniques. Always use the restraining equipment for both the operator and the
saw.

• Always wear safety protective equipment such as jacket, trousers,

gloves, boots with steel toe-caps and non-slip soles whenever you
use a chain saw. For working in trees the safety boots must be
suitable for climbing techniques. Do not wear loose clothing, jewelry,
short pants, sandals or go barefoot. Secure hair so it is above
shoulder length.

2. Remove the side case (1) while pinching the rear part of the side case (1) .(Fig.1 -1)

3. Install, the chain bar (1) onto the bolts (2), then push it toward the sprocket (3) as far as it will go. Make sure that the
boss of chain tension adjust bolt (4) fits into the hole of the bar (5). (Fig. 1-2)

NOTE!

Slightly move the bar back and forth and make sure the chain tension boss (4) fits into the hole (5) in the bar properly.

4. Confirm the direction of saw chain (1) is correct as in the figure, and align the chain on the sprocket. (Fig. 1-3)

5. Guide the chain drive links into the bar groove all around the bar.

6. Install the side case (1) onto the guide bar clamp bolts after inserting it on the alignment/locking tab on the engine case
(2). (Fig. 1 - 1 )

Then fix the clamp nuts temporarily.

7. Raise the bar end, and tighten the chain (1) by turning the
tension adjustment bolt (2) clockwise. To check proper tension,
lightly lift up the center of chain and there should be about 0.5-

1.0 mm clearance between bar and edge of drive link (3).

CAUTION!

• PROPER TENSION IS EXTREMELY IMPORTANT! (Fig.1 -4, 5)

8. Raise the bar end and securely tighten the chain bar clamp nuts with the box wrench. (Fig. 1 -4)
