Check oil level
Proceed as follows:
•
Switch off the vacuum system.
•
Wait 1 minute after switching off the vacuum pumps, before checking the oil level.
The oil level should be constant over the entire service life. If the oil level drops, the gear box
is leaking and the vacuum pump needs to be repaired.
Top up with oil if necessary (chap. 0).
