Maintenance
Inspections
Regular inspection at intervals dependent upon service conditions is
the best insurance against costly maintenance and breakdown.
Experience is the best guide. Record inspection results and
maintenance action required or performed.
Cleanliness
Keep the interior parts of machines clean and dry. Remove dust, dirt,
corrosion, grease, oil and moisture. If used, ventilating air filters must
be kept clean or replaced to assure full volume of cooling air.
Lubrication
Amount of grease to be added to motors is shown in Table G . See
Table I for relubrication interval.
For motors operating in ambient temperatures shown below, use the
following lubricants or their equivalent:
Ball Bearing Motors
Roller Bearing Motors

Using the table below, determine service condition on the basis of the
most severe operating parameter (i.e. temperature, bearing load,
atmosphere, or operating hours per day).

ATTENTION: Internal parts of this motor may be at line
potential even when it is not rotating. Before performing
any maintenance which could result in contacting any
internal part, be sure to disconnect all power from the motor.
Failure to observe this precaution could result in severe
