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.

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;...

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.

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.
4.3 Starting and turning off In the first start-up of the engine and every time the gasoline line (tank, pipe, primer bulb and carburetor) remains without fuel, you will need to fill the circuit before starting the motor. To do that, it is necessary to make pressure on the primer bulb of the gasoline and at the same time, with care, on the valve of the carburetor (indicated with number 6 in the following picture 4.5) up to the filling of the pipeline.
4.5 Carburetor adjustment A simple and fast control. You don't have any experience or affinity with the motors? Don’t worry, follow step by step what we tell you in this chapter. For years, our ambition has been to supply a simple product and accessible to everyone, trying to get simple and effective solutions for those who doesn't have experience of motor’s adjustements.
4.5.1 / sticker lock Whenever you choose to verify the carburetor settings, proceed in this way: completely close the screw L and H and then open them exactly with the standard setting, as described on chart 4.5. Remember: a strong pressure (tightening) on these screws can irremediably damage the carburetor.
Page 12
Watch out for the regulation of the screw H, because if this is too closed compared to indicated values, you could have damages to the motor. No damage will occur if the carburetion of the screw H is too opened (rich). If you have doubts, is always better to have a rich carburetion for the screw H.

4.6 Break-in A phase of break-in executed with care, improves the duration and the performances of the motor. The motor must be used with care in the first 5 hours of the break-in (15-20 liters). The first start-up of the motor must be made on the ground (on shoulder), warming up the motor for few minutes and paying attention to anomalous behaviors or noises.
4.7 First check-up Here below the list of check-ups that must be effected during the first 10 operating hours. It won't be necessary to repeat these controls after the 10hrs. tightening of the head nut (16-17N/m) after 2hrs and 10hrs, always when the •...
