LUBRICATION
Engine lubrication uses an oil pump which is located inside the oil sump.
The gearbox and clutch use the same oil and the recommended type is
CASTROL SAE 20W-50, with a total capacity of 1 liter.
The oil sump may be drained using the drain screw located at the lower
left of the engine. It is recommended that the oil change operation be
carried out while the engine is still warm as the sump will be cleaner and
the oil will drain out with greater ease because it will be more fluid.
Remove the drainage screw and allow it to empty completely.
Replace the screw once it is empty and refill by removing the dip-stick.
One litre must be poured in since if the motor is not started, approxi-
mately 80 c.c. will always remain inside.
