where the idling speed is maximum then move
the needle back a quarter turn anti-clockwise.
4. Turn the idle adjusting screw T anti-clockwise so
that the saw chain does not turn. If the idling
speed is too slow, turn the screw clockwise.

cutting power, not for maximum speed.

CHAIN BRAKE
This machine is equipped with an automatic brake
to stop saw chain rotation upon occurrence of
kickback during saw cutting. The brake is
automatically operated by inertial force, which acts
on the weight fitted inside the front guard.
This brake can also be operated manually with the
front guard turned down to the guide bar.
To release the brake, pull up the front guard toward
the front handle till “click” sound is heard (F13).

CLUTCH
To check the operation of the clutch run the saw at idle
speed and there shoud be no movement of the chain. If
chain moves there may be clutch wear or idle is
adjusted too high.
