you feel some resistance, then tug it hard a few
times until you hear the engine turn over.
WARNING!
cable around your hand.
DANGER!
by holding on to the starter cable and
allowing it to fall. This is an extremely dan­
gerous method as you lose complete control
over the machine and the chain.
IMPORTANT
er rope, do not pull the whole length of it or let it
slide along the edge of the cable guide hole.
Release the starter gradually, to avoid letting it fly
back uncontrollably.
7. Pull the starter rope again until the engine
starts as normal.
NOTE
starting, allow the starter knob to run back half
way to prevent flooding the engine.
NOTE
repeatedly with the choke on, it may flood the
engine and make starting difficult. If you have
flooded the engine, remove the spark plug and
gently pull the handle on the starter rope to elim­
inate any excess fuel; then dry the spark plug
electrodes and replace it on the engine.
8. When the engine has started, press the throttle
trigger to disconnect the starter and allow the
engine to idle.
IMPORTANT
high power with the chain brake engaged, as this
could cause overheating and damage to the
clutch.
9. Let the engine run idle for at least 1 minute
before using the machine.

When hot starting (immediately after stopping the
engine), follow the procedure indicated above in
points 1 - 2 - 5 - 6 - 8.

USE OF THE ENGINE (Fig. 10)
IMPORTANT
brake, pulling the lever towards you before using
the accelerator.
The chain speed is regulated by the throttle trig-
ger (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.
IMPORTANT
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!
speed to a minimum, it may take a few
seconds for the chain to stop.
USING THE ANTI-FREEZE DEVICE (For mod-
els 3700 and 4000 only)
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 sup-
plied to the engine and to thereby prevent icing
from occurring.
