6. HOW TO START – USE – STOP THE ENGINE
STARTING THE ENGINE
CAUTION!
The engine must be started in an area
at least 3 metres from where you refil-
led the fuel tank.
Before starting the engine:
–
Place the machine firmly on the ground.
–
Take off the bar cover.
–
Make sure the bar is not touching the ground
or any other object.
Cold starting
A "cold" start of the engine means star-
ting it after at least 5 minutes from when
it was switched off or after refuelling.
To start the engine (Fig. 8):
1. Check that the chain brake is engaged (with
the front hand guard pushed forward).
2. Set the switch (1) to «START».
3. Pull the choke (2) as far as possible to engage
the starter.
4. Press the primer device button (3) at least 5
times to prime the carburettor.
5. Press the decompression valve button (4 –
only for Mod. 46 and 52); the device turns
off and the button automatically returns to its
original position immediately after the engine
starts.
6. Hold the machine firmly on the ground, with
your hand on the handgrip and your foot in the
rear handgrip, to avoid losing control during
starting (Fig. 9).
CAUTION!
If the machine is not held firmly,
the force of the engine could
cause the user to lose his balance
or direct the bar towards him or an
obstacle.
7. Pull the starter rope slowly for 10 - 15 cm until
you feel some resistance, then tug it hard a
few times until you hear the engine turn over.
CAUTION!
Never wind the starter cable
around your hand.

DANGER!
Never start the chain saw by hol-
ding on to the starter cable and
allowing it to fall. This is an ex-
tremely dangerous method as you
lose complete control over the
machine and the chain.
To avoid breaking the starter rope,
do not pull the whole length of it or
let it slide along the edge of the cable
guide hole. Release the starter gra-
dually, to avoid letting it fly back un-
controllably.
8. Retract the starter knob (2); this condition is
indicated by the protruding red pin (2a).
9. Pull the starter rope again until the engine
starts as normal.
If the starter rope is pulled repeatedly
with the choke on, it may flood the
engine and make starting difficult.
If you have flooded the engine, re-
move the spark plug and gently pull
the handle on the starter rope to eli-
minate any excess fuel; then dry the
spark plug electrodes and replace it
on the engine.
10. When the engine has started, press the
throttle trigger to disconnect the starter and
allow the engine to idle.
Do not let the engine run at high
power with the chain brake engaged,
as this could cause overheating and
damage to the clutch.
11. Let the engine run idle for at least 1 minute
before using the machine.
Hot starting
For hot start (immediately after turning off the
engine) pulling the starting cord normally suf-
fices.
In the event of difficulty:
–
Pull the starter knob (2) fully out and
push it back in so that the red pin (2a)
protrudes.
–
Pull the starter cord grip until the engine
starts as normal.
–
When the engine has started, press the
throttle trigger to disconnect the starter
and allow the engine to idle.
