Most of the information in this document is taken from the Baldor Electric Company Instruction,
Operation, and Maintenance Manual, and provides a means of more accurately determining motor
lubrication requirements based on local conditions.
7U^UbQ\=QY^dU^Q^SU
Inspect, clean, and test motors at regular intervals— approximately every 500 operating hours
or every three months, whichever comes first. Lubricate motors at the intervals determined herein. Keep
accurate maintenance records.

—Keep the exterior of the motor free of dirt, oil,
grease, water, etc. Keep ventilation openings clear. Oily
vapor, paper pulp, textile lint, etc., can accumulate and
block ventilation, causing overheating and early motor
failure.

—Periodically, check the motor and winding
insulation integrity using a “megger.” Record the megger
readings and immediately investigate any significant drop
in insulation resistance. Check all electrical connectors to
be sure they are tight.

—Determine the proper lubrication interval
for your motor as explained in “How to Determine
Lubrication Interval” in this section, and lubricate
accordingly.
