DRAINING AND CLEANING OIL SYSTEM
DANGER
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
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. Be sure the unit is completely off and that no air pressure is in the oil reservoir.
2. Disconnect, lockout and tagout the power supply to the starter.
3. Using the oil reservoir drain, empty the oil reservoir through the drain valve into a suitable container
group.
4. 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. Inspect the oil separator elements for dirt accumulation;
replace if necessary. If a varnish deposit exists, contact the factory for recommendations for
removal of the deposit and prevention of varnish.
