NON-MANUAL CHAIN BRAKE
The non-manual chain brake stops the operation of the
saw chain in such a manner that kickback action
produced at the end of the guide bar non-manually
actuates the chain brake.
To make sure that the non-manual chain brake
operates properly, proceed as follows:
1) Stop the engine of the chain saw.
2) Operate the front and rear handles with hands (grip
them lightly), so that the guide bar may be placed at
the height of about 35cm as shown in Fig.

GENERAL
In all circumstances the operation of the chain saw is a
one-man job.
It is difficult at times to tack care for your own safety, so
don't assume the responsibility for a helper as well.
After you have learned the basic techniques of using
the saw, your best aid will be your own good common
sense.
The accepted way to hold the saw is to stand to the left
of the saw with your left hand on the front handle so you
can operate the throttle trigger with your right index
finger.
Before attempting to fell a tree, cut some small logs or
limbs.
Before thoroughly familiar with the control and the
