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 performances 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. 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.
