TROUBLESHOOTING GUIDE (cont'd)
PROBLEM
Motor overheating.
(Continued)

appears milky in color.
Liquid water or moisture in air
lines.
MG6-OLVERT-3B Rev. 0 12/30/99
CAUSE
Too many motor starts per hour.
Improper wiring gauge.
Incorrect voltage.
Current style electric motors run relatively hot under normal operating conditions, with
reasonable 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.
Humid operating conditions.
Unit not reaching proper operating
temperature because the compressor
runs infrequently and is oversized for
the air requirement.
Condensation forms in air lines when
the warm compressed air coming from
the air tank starts to cool down as it
travels through the air lines.
Consult Service Center.
Check electrical hookup and installation data or con-
sult electrician.
NOTE
Relocate compressor outfit, or change oil frequently.
Consult Service Center.
Install compressed air dryer sized for the flow and
dryness level required.
