Before starting the engine:
1. place the machine firmly on the ground;
2. remove the cutting means
guard (Fig. 1.L) (if in use);
3. make sure the blade (Fig. 1.D.2, Fig. 1.D.3,
Fig. 1.D.4, Fig. 1.D.5, Fig. 1.D.6) (if used) is
not touching the ground or any other object.
Result
Not damaged or worn.
Sharp
Clean
Undamaged to

correctly on the spark plug
Result
Cutting means (Fig.
1.D.1, Fig. 1.D.2, Fig.
1.D.3, Fig. 1.D.4, Fig.
1.D.5, Fig. 1.D.6) must
not move when the
engine is running idle.
The levers must move
freely and not be forced.
The levers must return
automatically and rapidly
to the neutral position
and the engine must
return to running idle.
the throttle trigger
lever remains
blocked(Fig. 12.B).
The switch must
easily move from one
position to the other;
6.3.1 Startup from cold
A "cold" start of the engine means
starting it after at least 5 minutes from when
it was switched off or after refuelling.
IMPORTANT To prevent distortions, the
drive tube must not be used as a support
for the hand or knee during startup.
IMPORTANT To avoid breaking the starter
cable, do not pull the whole length of it or
let it slide along the edge of the cable guide
hole. Release the starter grip gradually,
to prevent it flying back uncontrollably.
1. Turn the switch (Fig. 12.A) to the «I» position.
2. Engage the choke by moving the
lever to position «B» (Fig. 12.E).
3. Press the primer device control button (Fig.
12.F) 10 times to help start the carburettor.
Make sure that the hole is covered by
your finger when pressing the bulb.
4. Hold the machine firmly on the ground
with one hand on the power unit,
in order not to lose control of the
machine during startup (Fig. 14).
5. Pull the starter rope slowly for 10 - 15 cm until
you feel some resistance, then tug it a few
times until you hear the engine turn over.
6. Disengage the choke by moving the
lever to position «A» (Fig. 12.E).
7. Pull the starter grip again until
the engine starts as normal.
8. Activate the throttle trigger lever
briefly (Fig. 12.B) and switch the
engine to minimum speed.
9. Let the engine run idle for at least 1
minute before using the machine.
IMPORTANT If the starter grip is
pulled repeatedly, it may flood the
engine and make starting difficult.
If the engine floods (see paragraph 14).
6.3.2 Warm start
When hot starting (immediately after stopping
the engine), follow the procedure indicated
above in points 1 - 2 - 3 - 4 - 6 - 7.

6.4 WORKING

NOTE Before tackling a mowing job for the
first time, get to know the machine, learn the most
suitable cutting techniques, make sure your wear
the harnesses correctly, grip the machine firmly
and make the movements required by the job.
