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.
A
STOP
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 (1) will
automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand
guard (1) forward (towards the tip of the saw) with your left hand
(arrow 1).
Releasing the chain brake
Pull the hand guard (1) towards you (arrow 2) until you feel it
catch. The brake is now released.

Chain brake
The DCS6400, 6401, 7300, 7301, 7900, 7901 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 10), 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 work!
