Figure 5-2 Approximate Oil System Capacities - Gardner Denver EBB BB-7.5 HP Operating And Service Manual

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.
Excessive oil carry–over can damage
equipment. Never fill oil reservoir
above the "FULL" level.
COLD AMBIENT OPERATION – See "Installation for
Cold Weather Operation," and FIGURE 2–3, Section
2, pages 9 and 10.
HIGH TEMPERATURE OPERATION – If the dis-
charge temperature is sustained between 200–210 F
for a period of more than four (4) hours due to continu-
ing high ambient air temperature, use Gardner Den-
ver AEON 9000 SP Lubricating Coolant which is
a superior synthetic lubricant. Short periods of up to
four (4) hours of sustained discharge temperatures up
to 210 F do not require a change from the recom-
mended year–round lubricant AEON
LUBRICANT UPGRADE 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 filter and reinstall used filter.

2. Fill system with a 50 percent charge of the new lu-
bricant:
– Start the machine and stay there to observe.
– Allow the machine to run about five minutes at
temperature, or until temperature stabilizes,
then shut down.
3. Thoroughly drain machine.
4. Change to a new filter and separator.
5. Fill system with a full charge of the new lubricant.
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 system, change filter
and separator, and replace with full charge of
the new lubricant.
7. Subsequent lubricant changeouts should be at
normal intervals. (See "Oil Change Interval" and
chart, page 26.)
Improper equipment
with use of synthetic lubricants will
damage equipment. Oil filter and oil
separator change intervals remain
the same as for AEON
