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
aff,
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.
Chain
brake
The DCS
6400.6401,7300,7301,7900,7901
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
9),
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 emergen-
CY-
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!
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
(I)
fotward (towards the tip
of
the saw) with your
left
hand
(arrow
1).
Releasing the chain brake
Pull the hand guard
(2)
towards you (arrow
2)
until you feel it
catch. The brake is now released.
