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.

Tightening the saw chain

Turn the retaining nuts (A/2) approximately one turn with

the universal wrench. Slightly lift the end of the guide bar

and turn the chain adjusting screw to the right (clockwise) until

the chain rests against the bottom side of the guide bar.

While still holding up the guide bar, tighten the retaining nuts

(A/2) with the universal wrench.

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 PS-34 and PS-45 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 6,

10, 11), the chain brake will stop the chain through inertia if the

kickback is sufciently 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 emer-

gency.

IMPORTANT: NEVER run the saw with the chain brake

activated (except for testing, see “Checking the chain bra-

ke”)! Doing so can very quickly cause extensive engine

damage!

ALWAYS release the chain brake before starting the

work!
