The chain has the proper tension when it lies against the
bottom edge of the guide bar and can be easily pulled by hand
about 5 mm (a little under 1/4") up from the guide bar.
Check the chain tension frequently - new chains tend to get
longer during use!
When checking the chain tension the motor must be switched
off and the power supply plug pulled out.
HINT:
Use 2 or 3 saw chains alternately for even wear of the chains,
sprocket and guide bar running surfaces.
In order to guarantee a uniform wear of the groove in the bar the
bar should be turned over whenever replacing the chain.

The ES-151, ES-161 and ES-171 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 5), 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.

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
(I/11) will automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand
guard (I/11) forward (towards the tip of the saw) with your left
hand (arrow 1).
Releasing the chain brake
Pull the hand guard (I/11) towards you (arrow 2) until you feel
it catch. The brake is now released.
Note:
When the chain brake is actuated the power supply to the motor
will be cut off. Testing of the chain brake is described on page
12.

Chain brake maintenance
The chain brake is a very important safety feature, and like
any other part it is subject to a certain amount of wear.
Regular inspection and maintenance is important for your
personal safety, and can be properly performed only by a
DOLMAR service center.
