WHAT YOU NEED TO KNOW
The engine performance, reliability and life are inuenced by many factors, some external and some
strictly associated with the quality of the products used and with the scheduled maintenance.
The following information allow a better understanding and use of your engine.
ENVIRONMENTAL CONDITIONS:
The operation of a four-stroke endothermic engine is aected by:
a) Temperature:
– Working in low temperatures could lead to a dicult cold starting.
– Working in very high temperatures could lead to a dicult hot starting due to the evaporation
of the fuel either in the carburetor oat chamber or in the pump.
– In any case, the right kind of oil must be used, according to the operating temperatures.
b) Altitude:
– The higher the altitude (above sea level), the lower the max power developed by an endothermic
engine.
– When there is a considerable increase in altitude, the load on the machine should be reduced and
particularly heavy work avoided.
OIL:
Use always high quality oils, choosing their viscosity grade according to the operating temperature.
a) Use only detergent oil classied SJ,SL or higher are acceptable.
b) Choose the SAE viscosity grade of oil from this chart:
– from 5 to 35 °C = SAE 30
– from -25 to + 5 °C = 5W-20 or 5W-30 (Multi-viscosity)
– from -7 to + 35 °C = Synthetic oils 10W-30 or 15W-40 (Multi-viscosity)
c) The use of multi-viscosity oils in hot temperatures will result in higher than normal oil consumption;
therefore, check oil level more frequently.
d) Do not mix oils of dierent brands and features.
e) SAE 30 oil, if used below 5°C, could result in possible engine damage due to inadequate lubrication.
f) Oil should be at “MAX” mark do not overll. Overlling with oil may cause:
– Smoking;
– Spark plug or air lter fouling, which will cause hard starting.
AIR FILTER:
A good quality fuel is the major issue for the engine reliability of operation. The air lter must always
be in perfect working order, to prevent debris and dust from getting sucked into the engine, reducing
the eciency and life of the machine.
a) Always keep the ltering element free of debris and in perfect working order.
b) If necessary, replace the ltering element with an original spare part. Incompatible ltering ele-
ments can impair the eciency and life of the engine.
c) Never start the engine without mounting the ltering element properly.
