During the operation of decanting, mixing, filling, choose an open place, ventilated, clean
and away from dusts, sand, grass and everythings that can obstruct the passage of the
gasoline. If possible while filling the tank of the aircraft, filter the mixture. Be sure that the
tank for the transport gasoline, filter and funnel, is perfectly always clean.
We advise only oil of good quality certified and full synthetic (no oil semi-synthetic, no
mineral oil).
We recommend the use of the following types of oil, already tested with success
on our motors:
Motul 600, Castrol TTS, Valvoline Racing 2T.
Avoid mixtures prepared by the gas pump. A mixture had been prepared from 2-4 weeks
and left in a tank could separate (oil and gasoline), loosing the characteristics of lubrication
even if shaked before the use. Avoid to prepare a big quantity of mixture, when you are
already conscious to use only a part of it. Avoid use plastic tanks and consider it as
containers to transport, not left to deposit the mixture for days in the plastic tanks. We
dissuade the addition of liquids that increase the number of octanes.
In the first starting of the engine and every time the gasoline piper remains without fuel
(tank, pipe, primer bulb and carburetor), will need to fill the circuit before starting the motor.
To do that, it is necessary make pressure on the primer bulb of the gasoline and at the same
time, with care on the valve of the carburetor (indicated with the number 6 in the following
picture 4.5) up to the filling of the pipeline. It will be easy to see through a transparent
pipeline the gasoline that enters into the carburetor. For a good starting of the engine
when the circuit is empty or the motor is cold, need to enter just a few of gasoline in the
carburetor. This small quantity of gasoline, will work as starter/choke to the motor. Attention
if the quantity of gasoline that you push with the pomp to the carburetor is excessive, there
is the risks to flood the motor, even then to damage the pull starting.
The best starting of the motor Vittorazi is gotten without throttle or with a minimum of
throttle. If the circuit of fuel is on pressure and the motor is warm, it won’t be necessary to
make pressure on the primer bulb and valve.

STARTING AND TURNING OFF
Always watch out for the propeller during the starting and for whom could be nearby.
Many accidents happen before going to flight. On every test or warm-up, we suggest
to always wear the paramotor on your shoulder, to fast the harness, then to turn on
the engine with the pull or electric starter, ready however with the killing button to
stop the motor in every moment.
Important: often verify that the killing button is working. Sometimes the killing
buttons can get jammed or during the time can stop working.
You softly get throttle in the first 30 seconds allowing to stabilize the carburetor and the motor.
Now you increase the number of turns (thin to 1/4 around of throttle) and let warm-up the motor
for 2-3 minutes to this constant speed. Finally get the motor for some second (15-20 seconds)
at full throttle. Now your motor is ready to the flight. These 3 minutes of warm-up also have to be
dedicated, thanks to your attention, to understand if the motor has some anomalous behaviors,
if there are unexpected vibrations or noises not desired.
