The cain saw 694 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 30), the chain brake will stop the chain through
inertia if the kickback is sufficiently strong. The chain will
stop within a fraction 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 emergency.
IMPORTANT: 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 saw!

Tightening the chain
-
Slightly lift the end of the guide bar and turn the chain
adjusting screw (H/4) to the right (clockwise) until the
chain rests against the bottom side of the guide bar.
-
Continue to lift the guide bar end and firmly tighten the
two fastening nuts (G/1) by means of the universal
wrench.
-
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 in short intervalls because new
chains tend to elongate.
-
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 a uniform wear of the guide bar the
bar should be turned over whenever replacing the chain.
K
Actuating the chain brake (blocking)
If the kickback is strong enough the sudden acceleration of
the guide bar combined with the inertia of the hand guard
(K/3) will automatically actuate the chain brake.
When actuating the chain brake manually, press the hand
guard (K/3) with your left hand in the direction of the
guide bar end (arrow 1).
Releasing the chain brake
Pull the hand guard (K/3) in the direction of the tubular
handle (arrow 2) until it will engage noticeably. Now the
chain break is released.
