the accelerator.
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!
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.
IMPORTANT
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
engine to run idle for a few seconds.
– Set the switch (4) to «STOP».
WARNING!
When you have reduced
speed to a minimum, it may take a few
seconds for the chain to stop.
IMPORTANT
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.

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.
