Oil Change Interval; Draining And Cleaning - Gardner Denver EDF-KB Operating And Service Manual

OIL CHANGE INTERVAL – Recommended oil change
intervals are based on oil temperature. FIGURE 5–5,
shows how the change interval is affected by tempera-
ture.
When operating conditions are severe (very dusty, high
humidity, etc.), it will be necessary to change the oil
more frequently. Operating conditions and the appear-
ance of the drained oil must be surveyed and the oil
change intervals planned accordingly by the user.
Gardner Denver offers a free oil analysis program
with the AEON lubricants and we recommend a sam-
ple be sent in at 100 hours on a new unit.
DRAINING AND CLEANING OIL SYSTEM
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.
Always drain the complete system. Draining when the
oil is hot will help to prevent varnish deposits and carry
away impurities.
To drain the system, use one of the following methods:
1. If the unit is not elevated high enough to use the
oil reservoir drain line to drain oil, a small hand,

electric or air operated pump should be used to
drain reservoir through the oil filler opening or from
the drain valve.
2. If the unit is elevated so that the oil reservoir drain
can be used, empty the oil reservoir through the
drain valve to a suitable container or sump.
3. If the drained oil and/or the oil filter element are
contaminated with dirt, flush the entire system:
reservoir, oil cooler, mixing valve and lines. In-
spect the oil separator elements for dirt accumula-
tion; replace if necessary. If a varnish deposit ex-
ists, contact the factory for recommendations
for removal of the deposit and prevention of var-
nish.
