CHAIN LUBRICATION (Fig. 61)
Proceed to chain lubrication frequently (see ≈LU-
BRICANT CHART∆), every 4,000 km, every time the
vehicle is used off-road on mud or sand.
CHAIN CHECKING (Fig. 62)
From time to time check the wear condition of the
chain; make sure that it is not too loose and that there
are no angles or seized links.
If any faults are found, change the chain.
Never fit a new drive chain on a sprocket
wheel/ crown gear with very worn teeth;
vice versa do not use a worn chain on a new
sprocket wheel/crown gear.
