(may be a detergent oil with a tendency to foam)

•Inferior grade of lubricant

Excessive current draw

•Low voltage

(must be within 10% of name plate voltage)

(To determine maximum

•Loose electrical connection

amper age allowed, multiply

•Wire size too small

the FLA on the motor

•Incorrect lubricant

nameplate by the service

•Discharge pressure too high

factor.)

•Intercooler plugging

CAUTION !

•Bearings tight or seizing

Motor surface temperature •No crankshaft endplay

normally exceeds 170° F.

•Motor sized incorrectly

•Motor defective

•Drive belts too tight

Failure to start

•Power not on
