Operation Manual

- Turn the chain tightener (G/6) to the right (clockwise)
until the chain engages the guide groove of the bottom
side of the bar (see circle). Press the guide bar against the
housing with your left hand.
- Replace the sprocket guard (H/4).
- Manually tighten the retaining nuts (H/3).

Tightening the saw chain
- Slightly lift the end of the guide bar and turn the chain adjust-
ing screw (I/6) to the right (clockwise) until the chain rests
against the bottom side of the guide bar.
- While still holding up the tip of the guide bar, tighten the
retaining nuts (H/3) with the universal wrench.

Checking the chain tension
- The tension of the chain is correct if the chain rests against
the bottom side of the guide bar and can still be easily turned
by hand.
- While doing so the chain brake must be released.
- Check the chain tension frequently - new chains tend to get
longer during use!
- When checking the chain tension the engine must be switched
off.
NOTE:
It is recommended to use 2-3 chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.
Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of the
guide bar combined with the inertia of the hand guard (L/3) will
automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand guard
(L/3) forward (towards the tip of the saw) with your left hand (arrow 1).
Releasing the chain brake
Pull the hand guard (L/3) towards you (arrow 2) until you feel
it catch. The brake is now released.
The DOLMAR models comes with an inertia chain brake as
standard equipment. If kickback occurs due to contact of the
guide-bar tip with wood (see SAFETY PRECAUTIONS, page
6), the chain brake will stop the chain through inertia if the
kickback is sufÞ ciently strong. The chain will stop within a frac-
tion of a second.
The chain brake is installed to block the saw chain before
starting it and to stop it immediately in case of an emer-
gency. MPORTANT: NEVER run the saw with the chain brake
activated (except for testing, see “Testing chain brake”)! Doing
so can very quickly cause extensive engine damage!
ALWAYS release the chain brake before starting
the work!
