1.0 Introduction

Thanks for choosing a Vittorazi engine.
The user manual constitutes an integral part of the motor, it has to be preserved and
combined to the motor in case it will be delivered to a new user.
Before installing of the motor, read this manual carefully.
The purpose of this manual is to provide the user with all the information he needs to
manage the engine properly by himself and in the safest possible way.
It includes information about the technical aspect, operation, machine stop,
maintenance, spare-parts and safety.
If just one parts of the manual is not completely understood or in case the manual is not
clear or exhaustive, do not hesitate to contact either the authorized dealer or our factory
for any problem or question you might have.
Please include in the claim the serial number XXXX of the motor that you find under the
system carburetor, some photos if you think it is necessary.
You find the direct contacts of the factory in the first and in the last page of this manual.
The Vittorazi reserves the right to change in any moment without warning, sketches,
specifications, component, details of the motor, in relation to the model in production
without incurring in any obligation.
When you receive the motor, it will already have overcome a test of 15 minutes in the
factory, verifying the operation of all the components and the operation to every speed.
All Vittorazi engines are tested before the delivery.
The reliability, the performances and the duration of your motor will also depend from
your knowledge and the way you use it.

In this manual will be highlighted:

• in the red panel the situations that can lead you to a serious danger;

• in the blue panel, important suggestions or advice that must not be

underestimated.

Attention, danger, risk.

2.0 Warning

• Be aware that the motor can stop, have a breakup or to go off in any moment. This

could lead a crash to the ground or a landing in hostile areas with possible
damages/death of the pilot or other people. The ultralight moved by this motor
must fly in permitted spaces, it must not fly above a crowd of people, inhabited
centers, zones that have difficult or void landings, must not fly above zones of
water or where it is possible to drown. Always have in mind that the motor can go
off or breakup, therefore consider a possible landing of emergency for every
situation.

• This manual describes the motor. For its installation, use and control, compare also

the attached user manual of the ultralight: Paramotor, Mosquito or Trike.
If used in other applications, cannot be guaranteed the correct operation.

• This motor is not certified. It is not a motor with guarantees or aeronautical

certifications. Its construction is destined to experimental and not certified
aircrafts.

• Some zones for particular atmospheric conditions as pressure, temperature, damp

can bring to a different operation of your motor. Before beginning every flight, you
test the motor on the ground and verify that it doesn't have an anomalous
behavior.

• Start the engine in a plain surface, free from stones, sand or small parts that could

be aspirated by the propeller. Be sure that the flow of air pushed by the propeller
doesn’t cuase damage to anybody. Whenever the motor is running (testing on the
ground, take-off, landing) watch out that nobody stands near to the propeller in
rotation. A good safety distance is 50 meters for all directions of projection of the
propeller and 20 meters for the others directions.

• Do not use the motor that has not followed a correct maintenance or has not

correctly been used in the time or if you know that is not under perfect conditions.

• The use of non original spare-part and not recognized by Vittorazi, can make the

motor dangerous and immediately hands term to the validity of the warranty.
Vittorazi doesn't assume any warranty for that motor that are used with non
original parts or not recognized, modified or that have had an improper use.

• Unauthorized changes to the motor, to the reduction, to the propellers can reduce

safety and reliability of the aircraft. In case you have to intervene on the motor we
invite you to compare this manual with the help of your dealer Vittorazi and follow
it as reference.

• Before every use or test, check the conditions of the propeller and the tightening of

bolts of the propeller. If the propeller has received a hit and is damaged, avoid
using or turning on the motor. This can lead to an explosion of the propeller in
rotation or to strong vibrations that will revert in the motor with possible
consequent breakups, loss of tightening of the bolts or strong usuries of
components.

• Never use the motor without propeller or without reduction drive group. This

motor has been projected for a determined and contained number of turns.
Without propeller or reduction drive, the motor reaches a number of turns for
which it has not been calculated. In a few second there is risk of explosion of the
motor.

4.0 Get ready for the use

4.1 Propeller choice and mounting

Make sure you have a suitable and guaranteed propeller by Vittorazi for your motor.

The use of the propeller Vittorazi guarantees to our motors a perfect operation in
every condition of flight. Thanks to the continuous studies, on the test-bench it and to
the experiences in flight, we are able to realize propeller able to assure:

• absence of vibrations and stability during the time;

• best performance of the motor and improve fuel consumption;

• reduced noise emissions in relationship to the propeller diameter and to the

reduction;

• best cooling of the components.

Every single motor produced by Vittorazi is tested with its own propeller before the
delivery. In case of use of a propeller not recognized by Vittorazi, anomalies of
operation not related to the motor may occur, for instance:

• components break-ups caused by vibration;

• overheating of the thermal group;

• excessive noisiness;

• excessive fuel consumptions or insufficient thrust;

• non-constant power output.

The use of a not conform propeller with consequent anomalies already listed above or
the use of a right propeller Vittorazi but combined to a wrong reduction ratio, or the
use of accessories or components which are not authorized for this engine,
immediately voids of the warranty (see chapter 11.3).

Attention: the propeller can be mounted in two opposite positions compared with the
reduction drive. Ask the authorized dealer or the instructor, if you are not sure about the
propeller assembling.

In all versions of model Moster185 the propeller rotation is counterclockwise, considering
the back view (as per picture 4.1). Push the propeller against the reduction drive, until it
is completely inserted. Now gently screw the bolts up to the end. Be sure that the bolts
are suitable to the propeller in use, therefore the thread of the bolts is inserted for at
least 12mm (for carbon propellers) and 15mm (for wooden propellers) in the hub. Now
tighten the bolts of the propeller, trying to apply the same pressure on all points,
(picture 4.1). Do not exceed with the pressure on the bolts; you a risk to crush the
propeller.

Maximum pressure to apply:

• Carbon propeller: 10-12 N/m on every M6 bolt;

• Wooden propeller: 6-7 N/m on every M6 bolt (in accordance with the specifica-

tions provided by the propeller manufacturer, based on the type of wood
adopted).

Wooden propeller: once tightened the propeller, it is good to check that the pitch of the
two blades is identical. If there is a variation between the two blades, this difference can
be compensated through the pressure of the bolts.
If you don’t know this method of alignment, ask to an authorized dealer or instructor.
Check the tightening of the propeller before every flight.

In case of a damaged propeller, we invite you to purchase from a Vittorazi dealer, the
same propeller for measure and profile, guaranteed from the factory.
You just have to remember the size, material of the propeller and model of the motor

In the case of propeller impact, it is necessary to verify that all the engine parts have
not suffered any damage, paying particular attention to the components listed below:

• Reduction pulley and bearings;

• Reduction eccentric;

• Engine carter, engine carter support and engine rubber mounts.

4.2 Fuel

The motor that you are going to use is a two strokes engine. It requires an established
percentage of oil/gasoline for the lubrication.
The percentages will be pointed out in the following chapter, ("break-in" 4.6).

Gasoline is an extremely flammable and explosive substance. When you prepare or in
every moment you are close to the fuel (gasoline and oil), do not smoke, do not ignite
sparks or flames. Never fill the tank of your aircraft when the motor is running. Take
the fuel tank, at least 10 meters away from the engine, before to start it.

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 used for the transport of the gasoline, filter and funnel, are perfectly clean.

When at the gas pump, always choose unleaded gasoline 95 octanes.
We suggest to use only oil of good quality certified and full synthetic (no semi­synthetic oil, no mineral oil). We recommend the use of the following types of oil,
already tested with success on our motors: Motul 710.

Avoid mixtures prepared by the gas pump. A mixture that has been prepared from 2-4
weeks and left in a tank, could separate the oil from the gasoline, loosing the
characteristics of lubrication even if shaken before the use. Avoid to prepare big
quantities of mixture, when you are already conscious to use only a part of it. Avoid
using plastic tanks and consider it only as a container to transport the mixtue. Do not let
the mixture deposit for days in the plastic tanks. We dissuade the addition of liquids that
increase the number of octanes.
Problems occurred to the motor due to a lack of oil in the gasoline, or due to a wrong
percentage of oil in the mixture, or for lack of cleanliness of the gasoline, immediately
void the warranty. (See chapter 11.3).
