the chain bar (1) (Fig. 6). Continue until the chain can be moved smoothly but is
still closely seated (Fig. 5/pos. X2). Increase the tension by turning the bar fasten-
ing pin (Fig. 2/pos. B) in a
CLOCKWISE DIRECTION.
B
When the saw chain is correctly tensioned, hold the tip of the bar upwards and
completely tighten the bar fastening pin (Fig. 2/pos. B).
C
Secure the side cover (A) with the bar mounting nuts (11), by using the spark plug
spanner (19) (Fig. 7).
m
A new saw chain stretches, requiring adjustment after as few as 5 cuts. This is
normal with a new chain, and the interval between future adjustments will length-
en quickly.

If the saw chain is
TOO LOOSE or TOO TAUT, the drive wheel, chain bar, saw chain
and crank shaft bearing will suffer premature wear. Fig. 5/pos. X2 shows the correct
tension (when cold) and Fig. 5/pos. X3 shows the tension (when warm). Fig. 5/pos.
X1 shows a chain that is too loose.
Chain brake mechanical test
Your chainsaw is equipped with a chain brake that reduces the possibility of inju-
ry due to kickback. The chain brake is activated if pressure is applied against the
chain brake lever (3) when, as in the event of kickback, the operator’s hand strikes
the lever. When the chain brake is actuated, saw chain movement stops abruptly.
m
WARNING
The purpose of the chain brake is to reduce the possibility of injury due to kickback;
however, it cannot provide the intended measure of protection if the chainsaw is
operated carelessly. Always test the chain brake before using your saw and period-
ically while on the job. (See below for details of how to perform a test of the chain
brake).
To test chain brake (Fig. 8)
•
The chain brake is
DISENGAGED (chain can move) when the CHAIN BRAKE LEVER
(3) IS PULLED BACK AND LOCKED (pos.1).
•
The chain brake is
ENGAGED (the chain is locked) when the chain brake lever (3)
is pulled forward (pos. 2). It should not be possible to move the saw chain.
