The chain speed is regulated by the throttle trigger
(1) on the rear handgrip (2).
The throttle trigger only works if the lockout (3) is
pressed at the same time.
The movement is transmitted from the engine to
the chain by a centrifugal mass clutch that pre-
vents the chain from moving when the engine is
running at minimum speed.
WARNING!
the chain moves when the engine is running
idle; in this case, contact your dealer.
The correct running speed will be achieved by
pressing the throttle trigger (1) as far as possible.

USING THE ANTI-FREEZE DEVICE
(excluding C 46 - XC 246 - C 50 - CP 45
- A 455 - MC 846 models) (Fig. 11)
Operating chain saws in temperatures of 0 – 5°C
at times of high humidity may result in ice forming
within the carburetor, and this in turn may cause
the output power of the engine to be reduced or for

the engine to fail to operate smoothly.
This product has accordingly been designed with a
ventilation hatch on the right side of the surface of
the cylinder cover to allow warm air to be supplied
to the engine and to thereby prevent icing from
occurring.
Under normal circumstances the product should
be used in the normal operating mode, i.e., in
the mode which it is set at the time of shipment.
However when the possibility exists that icing may
occur, the unit should be set to operate in the an-
ti-freeze mode before use.
To switch from "Normal" mode to "Anti-freeze"
mode (and vice versa) (Fig. 11):
1. Switch the engine off.
2. Remove the air filter cover (1) and the air filter
(2).
3. Remove the choke (3) from the cylinder cover
(4).
4. Unscrew the screws (5) which secure the cylin-
der cover in place (three screws inside and one
outside) and remove the cylinder cover.
5. Use your fingers to press the anti-freeze cap (6)
on the right side of the cylinder cover and slide
it out from its seat.
6. Turn the anti-freeze cap (6) so that the "SNOW"
symbol is facing upwards and then replace the
cap.
7. Replace the cylinder cover and all the other
parts in their original position.
NOTE
ti-freeze mode at higher temperatures, this may
cause difficulties when starting the engine and
during use due to the incorrect engine speed. Al-
ways check that the machine is switched to normal
mode (with the "SUN" symbol facing upwards) if
there is no danger of ice forming.
