8.
Pour the prescribed quantity of oil in the oil filler inlet (F).
Information on the recommended oil, see section
"LUBRICANTS AND OPERATING AGENTS".
9.
After filling up oil, check the oil level:
NOTE
The oil level in the transmission can rise considerably when the
engine is not running. For this reason, only check the transmission
oil level with the engine idling. The gear-shift must be in its neutral
position.
1)
Turn the handle of the dipstick (G) anti-clockwise until it is
loose. Then pull out the dipstick and wipe off the oil with a
clean cloth.
2)
Push the dipstick into the filler nozzle (F) fully and pull out
again.
3)
Read off the oil level:
Range between markings 1 and 2:
operational range - oil temperature between 40°C and 80°C
Range between markings 2 and 3:
operational range - oil temperature between ambient
temperature and 40°C
below marking 3:
minimum when the oil is cold
4)
If the oil level is below the appropriate marking, top up with
fresh oil in the oil filler nozzle (F).
5)
If the oil level is above the appropriate marking, the excess
oil will have to be drained off from the drain plug (P) and the
oil level checked again.
6)
When the oil level is correct, insert the dipstick again and
tighten the cover by turning the handle on the cover clock-
wise.
7)
Check the transmission and filter for leaks.
