- Position the sprocket guard ( G/2 ).
Manually tighten the two fastening nuts ( G/1 ).
Tightening the chain
- Slightly lift the end of the guide bar and turn the chain
adjusting screw (
H/4 ) to the right (clockwise) until the chain
rests against the bottom side of the guide bar.
- Continue to lift the guide bar end and firmly tighten the two
fastening nuts (
G/1 ) by means of the universal wrench.

Actuating the chain brake (blocking)
If the kickback is strong enough the sudden acceleration of the
guide bar combined with the inertia of the hand guard (
K/3 ) will
automatically actuate the chain brake.
When actuating the chain brake manually , press the hand
guard ( K/3 ) with your left hand in the direction of the guide bar
end (arrow 1).
Releasing the chain brake
Pull the hand guard ( K/3 ) in the direction of the tubular handle
(arrow 2) until it will engage noticeably. Now the chain break is
released.

STOP
The PS-9010 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 10), 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 emer-
gency.
- 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 in short intervalls because new
chains tend to elongate.
- 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 a uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.
