LUBRICANT CHANGE PROCEDURE – Upgrading to
a longer life lubricant is essentially a very worthwhile
practice. Following are the primary steps to be com-
pleted when upgrading or changing the type of lubri-
cant.
1. Thoroughly drain system:
– Drain oil from air end and cooler while hot.
– Break low point connections and drain oil
from pipe runs.
– Dump oil from the filter and reinstall used fil-
ter.
2. Fill the system with a 50 percent charge of the new
lubricant:
– Start the machine and stay there to observe.
– Allow the machine to run about five minutes
at temperature, or until temperature stabi-
lizes, then shut down.
3. Thoroughly drain the machine.
4. Change to new filter and separator.
5. Fill the system with a full charge of the new lubri-
cant.
6. Machine should then be run normally, however,
total run time after the initial changeout should be
50 percent of normal anticipated service life of the
new lubricant.
– Drain all lubricant from the system, change
the filter and separator, and replace with a full
charge of the new lubricant.
7. Subsequent lubricant changeouts should be at
normal intervals. (See “Oil Change Interval” and
chart, page 29.)
Improper equipment maintenance
with use of synthetic lubricants will
damage equipment. Oil filter and oil
separator change intervals remain
the same as for AEON

4000 –– See
Maintenance Schedule, page 36.
Air/oil under pressure will cause
severe personal injury or death. Shut
down compressor, relieve system of
all pressure, disconnect, tag and
lockout power supply to the starter
before removing valves, caps, plugs,
fittings, bolts, and filters.
Compressor, air/oil reservoir, separa-
tion chamber and all piping and tub-
ing may be at high temperature during
and after operation.
