HOW TO START - USE – STOP THE ENGINE 11
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 prevents the
chain from moving when the engine is running at
minimum speed.
Do not use the machine if
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.
Avoid using the engine at full
power for the first 6-8 working hours.
STOPPING THE ENGINE (Fig. 10)
To stop the engine:
– Release the throttle trigger (1) and allow the en-
gine to run idle for a few seconds.
– Set the switch (4) to «STOP».
When you have reduced
speed to a minimum, it may take a few sec-
onds for the chain to stop.
If the machine does not turn
off, pull the starter to flood and stop the engine and
immediately contact the dealer to find the cause of
the problem and request necessary repairs.
USING THE ANTI-FREEZE DEVICE (exclud-
ing C 46 - XC 246 - C 50 - CP 45 - A 455 mod-
els) (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.

WARNING!
IMPORTANT
WARNING!
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 sup-
plied 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. How-
ever when the possibility exists that icing may oc-
cur, the unit should be set to operate in the anti-
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.
If the machine is used in anti-
freeze mode at higher temperatures, this may
cause difficulties when starting the engine and dur-
ing use due to the incorrect engine speed. Always
check that the machine is switched to normal mode
(with the "SUN" symbol facing upwards) if there is
no danger of ice forming.
