CHECKING THE ENGINE OIL LEVEL
The engine oil level can be checked when
the engine is cold or hot.
Place the vehicle in an upright position (not
on the side stand) on level ground.
When the engine is cold, the oil should
reach the lower edge of sight A.
When the engine is hot, the oil should
reach the upper edge of the sight.
Top up as necessary.
WARNING
The use of insuffi cient quantities of oil or
of oil of inferior quality results in premature
wear of the engine.
OIL CIRCUIT
The pump 1 (higth pressure) push oil to crank mechanism 4, to piston oil jet 5, to
stretcher 6, to head jet 7. The valve 2 control the pressure and the paper fi lter 3
scrubs the oil from subtle impurity.
When oil has lubricated the head and has pushed the chain stretcher, the oil goes in
generator room A. When oil has lubricated the crank mechanism and piston-cylinder
coupling, goes in the crank mechanism room B. Pump 1 sucks the oil from room B
across the wire netting fi ler 11 and the pump push the oil to room A.
The valve 10 controls the pressure between room A and room B.
