1) Change the oil in the gearbox housing.
This should be done on a level surface when the engine is hot. Allow oil to flow out through fitting (A),
(Fig. 20) and pour new oil through plug (T) which has a dip stick (Fig. 21).
Use the type and quantity of oil indicated in the Lubricants Table on page 25).
2) The clutch lever (3), (Fig. 22) must have a free play of approx. 5-6 cm before the clutch itself begins to
disengage. If play is more, THE CLUTCH WILL NOT COMPLETELY DISENGAGE; if play is less, THE CLUTCH
MAY SLIP.
In this case, adjust by means of adjuster (R) after having slackened check nut (D) in order to re-establish
the required free play.
