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

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. Mount the guide bar then fit the saw chain around

the bar and sprocket.

Pay attention to the correct direction of the saw chain.

4. Fit the chain tensioner nut into the lower hole of the

guide bar, then install the chain cover, and fasten
the mounting nut to finger tightness.

When installing the chain cover, be sure to fit the hook
completely at the rear end of the cover.

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

(11.8-14.7 N.m./120-150 kg-cm). Then check the
chain for smooth rotation and proper tension while
moving it by hand. If necessary, readjust with the
chain cover loose.

7. Tighten the tensioner screw.

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
itseif and the guide bar.
