LUBRICATION SYSTEM

LUBRICATION SYSTEM AND BREATHER RECIRCULATION SYSTEM

Danger – Attention
- The engine can be damaged if allowed to operate with
insufficient oil. It is also dangerous to add too much oil
because its combustion may lead to a sharp increase in
the rotation speed.
- Use suitable oil in order to protect the engine.
Nothing more than lubrication oil can influence the per-
formances and life of an engine.
- Use of an inferior quality oil or failure to regularly change
the oil will increase the risk of piston seizure, will cause
the piston rings to jam and will lead to rapid wear on the
cylinder liner, the bearings and all other moving parts.
Engine life will also be notably reduced.

- The oil viscosity must suit the ambient temperature in
which the engine operates.
- Old engine oil can cause skin cancer if repeatedly left in
contact with the skin and for long periods of time.
Wear protective gloves to avoid touching used oil.
- If contact with the oil is unavoidable, you are advised to
wash your hands with soap and water as soon as possible.
Dispose of old oil in the correct way as it is highly polluting.
