10.4 Oil change

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!
• Oil residue and other deposits must be
removed from the compressor coolers
which are exposed to hot air in
accordance with the user manual.
• Look for leaks! Immediately take care of
any spilled oil!
NOTICE
Catch the old oil, do not let it drain onto the
floor! Dispose of it properly! Do not spill any oil!
Look for leaks!
With these compressors, the frequency of the
oil changes is closely related to how dirty the
circulating oil is. Pay close attention that no
foreign substances which can damage the oil
(dust, steam, gases) make it through the air
intake filter into the compressor unitʼs oil circuit.
Very humid intake air and condensation inside
the machine have an influence on the life span
of lubricating oil so that the oil change times
must also be reduced in this case. The change
time intervals given are based on intake air
which is normally available and if foreign
substances (dust, steam, gases) are not
present in large amounts.
When changing the oil, the old oil must be
drained as fully as possible, because the used
oil strongly decreases the life span of the new
oil.
Different lubricating oils must not be mixed.
When changing this type of oil, the oil must be
completely drained from the oil circuit.
