4. Fit the chain cover to the power unit and fasten the

nuts to finger tightness.

5. While holding up the tip of the bar, adjust the chain

tension by turning the tensioner screw until the tie
straps just touch the bottom side of the bar rail.

6. Tighten the nuts securely with the bar tip held up

(12 ~ 15 N·m). Then check the chain for smooth ro-
tation and proper tension while moving it by hand. If
necessary, readjust with the chain cover loose.

7. Tighten the tensioner screw.

NOTE

A new chain will expand its length in the beginning of
use. Check and readjust the tension frequently as a loose
chain can easily derail or cause rapid wear of itself and
the guide bar.

3. Installing Guide Bar and Saw Chain

A standard saw unit package contains the items as illustrated.

Open the box and install the guide bar and the saw
chain on the power unit as follows:

WARNING

The saw chain has very sharp edges. Use thick pro-
tective gloves for safety.

1. Pull the guard towards the front handle to check that

the chain brake is not engaged.

2. Loosen the nuts and remove the chain cover.
3. Gear the chain to the sprocket and, while fitting the

saw chain around the guide bar, mount the guide
bar to the power unit. Adjust the position of the chain
tensioner.

NOTE

Pay attention to the correct direction of the saw chain.
