8.5.8. Lubricate front wheel
bearings (31) (2WD)
In dusty and muddy conditions, it is necessary for
lubrication to be carried out much more often.
When injecting new greese, ensure that enough is
injected so that it pushes the dirt out of the hub.
Check also the bearings tightness and if necessary
have them adjusted at an authorized workshop.

front wheels (32)
See under ”Checks and Adjustments”.
8.5.10. Check and adjust valve
clearance (33)
Exhaust valves clearance should be 0,45 mm and
inlet valves clearance should be 0,20 mm. The
valve clearance can be adjusted when the engine is
either warm or cold.
Checking and adjustment should be carried out by
an authorized workshop.
