2. When operating at very high temperatures 
warm starts may be difficult due to 
evaporation of the fuel in the float 
chamber of the carburettor or in the pump.
3. In any case the right kind of oil 
must be used, according to the 
operating temperatures.
b) Altitude:
4. The higher the altitude above sea level, 
the lower the max power developed 
by an endothermic engine.
5. When there is a considerable 
increase in altitude, the load on the 
machine should be reduced and 
particularly heavy work avoided.

3.6 FUEL

A good quality fuel is the major issue for 
the engine reliability of operation.
Fuel must meet these requirements:
a)    U se clean, fresh unleaded gasoline, 
with a minimum of 90 octane
b)    D o not use fuel formulated with 
more than 10% ethanol.
c)  Do not add oil
d)    T o protect the fuel system from gum 
formation, mix a fuel stabilizer into the fuel.
Use of unapproved fuels will cause 
damage to engine components, which 
will not be covered under warranty.
NOTE Only use the fuel named in the
technical data table. Do not use other types
of fuel. It is possible to use ecological fuels,
such as alkylate petrol. The composition of
this petrol has less of an impact on people
and animals. No negative effects have
been reported in connection to their use.
Nonetheless, there are types of alkylate petrol
on the market for which it is not possible to
provide specific indications on their use.

3.7 OIL

Use always high quality oils, choosing 
their viscosity grade according to 
the operating temperature.
• Only use detergent oil with a 
quality of no less than SF-SG. 
• Choose the SAE viscosity based 
on the technical data table.
• The use of multigrade oil can lead to greater 
consumption in hot weather, accordingly it is 
necessary to check the level more frequently.
• Do not mix oils of different brands 
and characteristics.
• SAE 30 oil, if used below +5°C, could 
result in possible engine damage 
due to inadequate lubrication.

3.8 AIR FILTER

The air filter must always be in perfect working 
order to prevent debris and dust from being 
sucked into the engine, thereby reducing 
the efficiency and life of the machine.
• Always keep the filtering element free of 
debris and in perfect working order (par. 6.5).
• If necessary, replace the filtering 
element with an original spare part 
Incompatible filtering elements can impair 
the efficiency and life of the engine.
• Never start the engine without mounting 
the filtering element properly.

3.9 SPARK PLUGS

Not all the spark plugs for endothermic 
engines are the same.
• Use only spark plugs of the recommended 
type, with the right heat range.
• Check the length of the thread, 
because - if too long - it will damage 
the engine beyond repair.
• Make sure that the electrodes are clean 
and that the air is correct (para 6.6).

4. COMMANDS

4.1 THROTTLE COMMAND

Regulates the engine's r.p.m.
The throttle control (usually a lever) 
mounted on the machine is connected 
to the engine by a cable.
Refer to the owner's manual to identify 
the accelerator lever and the its related 
positions, which are usually marked 
with symbols corresponding to:
• FAST= top speed; to be used during work.
• SLOW = low speed.

4.2 CHOKE COMMAND

Refer to the owner's manual to 
identify the Choke command.
