PROBLEM CAUSE
Air compressor Air compressor overworked.
overheating.
The outlet tube and/or check
valve is restricted.
Dirty air compressor.
High ambient temperature.
Motor overheating.
Incorrect oil, low oil.
Low voltage.
Pressure switch set beyond
factory setting.
Belt too tight.
Air compressor valves have
excessive carbon deposits
build-up; restricted check valve.
Too many motor starts per hour.
Improper wiring gauge.
Incorrect voltage.
Current style electric motors run relatively hot under normal operating
conditions, with reasonable air compressor loading. This condition is
normal and no adjustment is necessary.
Under normal operating conditions, the motor amperage draw will
not exceed the nameplate amperage rating, plus the service factor, as
it appears on the electric motor. If a condition of sustained high
amperage exists, refer to service checks above and/or consult
electrician. If cause cannot be isolated by an electrician, consult with
Service Center for additional assistance.
Water in pump Humid operating conditions.
crankcase; oil
appears milky in
color.
Unit not reaching proper
operating temperature because
the air compressor runs
infrequently and is oversized for
the air requirement.

coming from the air tank starts
to cool down as it travels
through the air lines.
CORRECTION
Reduce air consumption or add
another air compressor to take up
some of the load.
Check the tube and the check
valve. Clean if necessary.
Clean the air compressor
thoroughly.
Use remote air intake.
See oil recommendation on page
15.
Provide correct voltage. Consult
local power company or electrician.
Do not set switch beyond maximum
for which unit was designed as
noted on nameplate.
Adjust for proper tension.
Clean or replace air compressor
valves or check valve.
Consult Service Center.
Check electrical hookup and
installation data or consult
electrician.
NOTE
Relocate air compressor unit, or
change oil frequently.
Consult Service Center.
Install compressed air dryer sized
for the flow and dryness level
required.
