Checking the Oil Level

DANGER
Air/oil under pressure will cause severe
personal injury or death.
• Shut down the compressor, relieve the
system of all pressure, disconnect,
lockout and tagout the power supply to
the compressor package before
removing valves, caps, plugs, fittings,
bolts and filters.
CAUTION
Fire hazard and slip hazard!
• Do not spill any oil!
• Look for leaks! Immediately take care of
any spilled oil!
NOTICE
Do not mix oils with different specifications.
If the compressor system is delivered without
oil, oil must first be filled into the pressure
reservoir up to the "maximum oil level" mark.
(For oil filling also see Sections 10.4 and 10.13)

Check the oil level as follows:
Shut off the compressor with the STOP button.
•
Wait at least 5 minutes until the oil has settled, i.e.
•
until the air has bubbled out.
The oil level should be checked at each pause in
•
operation and at regular intervals using the
transparent plastic tube on the pressure reservoir
(- 2 - Fig. 15).
The oil level must lie between the "maximum oil
•
level" (- 3 - Fig. 15) and "minimum oil level"
(- 4 - Fig. 15) marks on the oil container.
If required, top up oil.
•
Close the oil filler cap (-1- Fig. 15) firmly.
