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.

Checking the chain tension

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.

Chain brake

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.
