BEFORE STARTING
Carefully read and follow all
instructions in this booklet as
well as all those provided with
the equipment on which this
engine is used.
Failure to do so will make
warranty void.
- The engine may bedamaged if operated with insufficient lubeoil. It is also dangerous to fill in too much oil to
theenginebecauseasudden increase in engine rpm could occur caused by itscombustion.Useproperlube
oilpreserveyour engine. Nothing affectsthe performance anddurabilityof your engine more thanthelube oil
you use. If inferior quality oil is used, or if your engine oil is not changed regularly, the risk of piston seizure,
pistonringsticking,and accelerated wear ofthecylinderliner,bearing and othermovingcomponentsincreases
significantly. Alwaysuse oilwiththe right viscosity for the ambienttemperaturein which your engine isbeing
operated . Use the chart on this page when chosing your engine oil.
- The used engine oil can cause skin-cancer if kept frequently in contact for prolonged periods. If contact
with oil cannot be avoided, wash carefully your hands with water and soap as soon as possible. Do not
disperse the oil in the ambient, as it has a high pollution power.
USE
SAE CLASSIFICATION
In the SAE classification, oils differ on the basis of their viscosity, and no other qualitative
characteristic is taken into account.
The first number refers to the viscosity when the engine is cold (symbol W = winter), while the
second considers viscosity with the engine at régime.
The criteria for choosing must consider, during winter, the lowest outside temperature to which
the engine will be subject and the highest functioning temperature during summer.
Single-grade oils are normally used when the running temperature varies scarcely.
Multi-grade oil is less sensitive to temperature changes.
SAE GRADE
* Mineral base ** Semi-synthetic base *** Synthetic base
