Engine oil change
For the intervals between oil changes see the
maintenance plan.
The refill quantity is ca. 7.5 liters.
1. With the engine warm, remove the oil filler
cap and the oil drain plug.
2. Let all the drain out and renew the filter.
When renewing a filter, no undue force
should be used to tighten it, (lightly oil the
sealing ring) as it will then be very difficult
to remove when doing the next filter change.
3. Screw the filter element up until it contacts
the sealing ring.
4. Screw the filter element a further half a turn.
5. Clean the drain plug and replace it, using a
new sealing ring.
6. Pour the new oil in, check the level and re-
place filler cap.
7 Run the engine and check for leaks.
8. Run the motor and check for leaks.
Oil level in gearbox
To check the oil level in the gearbox, the
plug (B) must be wiped clean and removed
by unscrewing.
With the vehicle standing horizontally, the oil
(cold) should be topped up to the lower lip of
the hole.
To refill the gearbox, only use the oils recom-
mended in the table "Filling quantities".
