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 installedto block the saw chain before startingitand to stop it immediately in case of an emergen-

CY-

IMPORTANT: NEVER run the saw with the chain brake activated (exceptfor 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 accelerationof 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 (towardsthe 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.
