OPERATION

28
The engine must not be used in a closed environment unless the room is
adequately ventilated. Combustion engines produce harmful gases which, in
closed and/or insufficiently aired environments, can reach concentrations that
may prove dangerous and/or lethal to people and animals. Protections for
pulleys, belts and propeller shafts do not always ensure the operator's full
safety; in particular, loose clothes may be trapped in the transmission parts
causing serious harm to people! Do not tamper with the engine in order to
improve its performance, the only consequence would be that of increasing
risks.

• Electric start

Before starting the engine make sure that all connections with the machine
(gearbox, clutch, etc.) are disconnected.
Bring the accelerator lever to half stroke ("A", figure 9-10). Turn the ignition key (figure
11) to position "B", then start the engine turning it to position "C". Once the engine has
been started, turn the ignition key back to position "B" (battery recharge) and bring the
accelerator lever to the minimum position.
Do not turn the key to position "C" (start) if the engine is running. In engines without
solenoid valve stop, if the ignition key is turned to the "A" position (figure 11) when
running, the voltage regulator components could be damaged. If the fuel circuit is
empty or if the temperature is too low, several attempts may be necessary before the
engine starts. In such cases, wait 15 seconds before trying any further attempt
otherwise the starter could be overheated.

• Recoil starting system

The engine is equipped with a device which allows automatic activation of decompres-
sion; to start up, simply pull the rope decisively (figure 12), to further facilitate start-up,
especially at low ambient temperatures, proceed as follows: pull the rope slowly, until
just after completion on the compression stroke (you will hear the injector click); at this
point, release the rope so that it rewinds, and then pull it decisiverly.

• Engine heating

We advise you against carrying out loadless heating procedures, particularly if heating
takes a long time, as they may cause bad combustion and, consequently, high levels of
smoke and oil spillage into the exhaust, and therefore gas pollution.

• Run-in

Follow the rules below during the run-in period (approximately 50 hours):
- pre-heat the engine for several minutes before loading;
- use the engine only partially laden;
- do not overload the engine for long periods;
- do not insist in using the machine if black smoke is exhausted;
- before stopping the engine idle for some minutes to cool it down.
We suggest replacing the engine oil at the end of the run-in period (50 hours).

• Engine stop

Bring the accelerator lever to the minimum ("A", figure 9-10), wait for a few seconds,
push the engine stop lever to the STOP position ("B", figure 9-10) and keep it pressed
until the engine stops completely. If the engine is fitted with a solenoid valve stop, turn
the ignition key to position "A" (figure 11).
Do not stop the engine when operating at full load or high speed.
Before stopping it. Let it run for a short time at low idle.
