Changing oil and oil filter
The first oil change must take place after 100 operating hours. Later oil changes af-
ter 3000 hours or every six months.
The vacuum pump must be at at operating state temperature when the oil is
changed:
•
Put the FAM into operation for 10 minutes
•
Shut off the FAM.
•
Wait until the pressure in the vacuum column is at atmospheric pressure (
≈
1000 mbar abs).
The following accessories are required for accomplishing these tasks:
•
Compressor oil VE101 (for part-no., see replacement parts list)
•
Maintenance set, comprising oil filter, air deoiling element, ventilation cover
seal (for part-no., see replacement parts list).
•
Fork wrenches SW 27 / SW 32
Replacing the oil:
Open the screw plug (
4
) / ball faucet to drain off the old oil.
Seal the screw plug when the flow of oil diminishes and then let the pump run
again briefly for a few seconds.
Open the plug screw once again and drain off the remaining oil.
Screw the plug screw back in tightly.
Remove the oil filter (
11
) and replace it with a new one.
Fill in new oil through the oil filling screw plug (5) until the MAX marking (3) has
been reached.
Replacing the Air De-oiling Element
Oil mist or increased electricity consumption by the drive engine (response of the
engine protection switch) can be traced back to a soiled air de-oiling element.
To carry out the replacement:
•
Remove the four attachment screws of the ventilation cover (10).
•
Undo the leaf spring safety screw (15).
•
Remove leaf spring (15).
•
Remove air deoiling element (9) and replace with a new one.
•
Replace ventilation cover seal (10).
•
Assembly in reversed order of sequence.

the BUSCH vacuum pump.
