EMAX Rotary Screw Compressors
Maintenance
Safety Steps
Disconnect, tag and lock out power
source then release all pressure from
the system before attempting to
install, service, relocate or perform
ANY maintenance.
When performing service in any
enclosure large enough to hold a
man, inform others then be sure
to tag and keep open any access
doors. Before closing and latching
access doors, make sure all
persons are clear from enclosure.
1. Make sure repairs are done in a clean, dry,
well lighted and ventilated area.
2. When cleaning, use air pressure less than 30
psig (2.1bar). Also use effective chip guard-
ing and personal protective equipment per
OSHA standard 29 CFR 1910.242 (b).
3. Relieve all internal pressure prior to opening
any line, fitting, hose, valve, drain plug, con-
nection or other component, such as filters
and line oilers, and before refilling optional
air line anti-icer systems with antifreeze
compound.
4. Keep sound reducing material, any external
surfaces of the air compressor or internal
surfaces of the enclosure free from fluids and
build-up. Clean with water based industrial
cleaner or steam clean as necessary. Remove
then replace sound reducing materials as
needed to clean all surfaces. Immediately re-
place any sound reducing material with torn
or punctured protective covering to prevent
accumulation of liquids or build-up inside
the material. NEVER use flammable solvents
for cleaning purposes.
5. Keep electrical wiring, including all terminals
and pressure connectors in good condition.
Replace any wiring that has cracked, cut, or
otherwise damaged insulation. Replace ter-
minals that are worn, discolored or corroded.
Keep all terminals and pressure connectors
clean and tight.
6. Keep all body parts and any hand-held
tools or other conductive objects away from
exposed live parts of the electrical system.
When making repairs or adjustments, stand
on a dry, insulated surface and DO NOT con-
tact any other portion of the compressor.
7. DO NOT leave compressor unattended with
exposed electrical components. Be sure to
tag and disconnect all power if temporary
absence is necessary.
Compressor components can
become hot during operation.
Avoid bodily contact with hot
liquids, hot surfaces and sharp
edges and corners.
Lubricating Oil
To avoid water condensation during operation, keep
oil temperature between 160-180˚ F. Failure to do
so will cause pump damage. Contact EMAX service if
temperature drops below 160˚ F.
Changing Oil:
1. Shut down compressor and allow machine to
set for 5-10 minutes.
Air/Oil Separator tank is a
pressurized component. To avoid
serious injury, be sure system
pressure is relieved before
removing fill cap. Be aware oil
temperature may be very hot. Use
caution when changing oil.
2. Drain oil completely. Be sure to include oil in
system piping, cooler and air/oil separator
tank. Close drain valve.
3. Remember to remove and change oil filter.
Be careful to avoid hot oil during replace-
ment.
4. Open oil fill port and add new oil.
Use only EMAX oil, model no.
AROL8000G1. For food
manufacturing applications, use model no.
AROLFOODG1. Use of any other product will cause
product damage and void the warranty. Refer to
warranty statement for oil requirements.
Failure to perform regular oil
changes may cause equipment
damage and will void warranty. Oil must be
changed annually regardless of hours used.
