General Inspection
Inspect the motor at regular intervals, approximately every 500 hours of operation,
or every 3 months, whichever occurs fi rst. Keep the motor clean and the ventilation
openings clear. The following steps should be performed at each inspection:
WARNING:
Do not touch electrical connections before you fi rst ensure that power
has been disconnected. Electrical shock can cause serious or fatal injury. Only
qualifi ed personnel should attempt the installation, operation and maintenance of
this equipment.
1. Check that the motor is clean. Check that the interior and exterior of the mo-
tor is free of dirt, oil, grease, water, etc. Oily vapor, paper pulp, textile lint, etc.
can accumulate and block motor ventilation. If the motor is not properly ven-
tilated overheating can occur and cause early motor failure.
2. Check all electrical connectors to be sure that they are tight.
Lubrication & Bearings
Bearing grease will lose its lubricating ability over time, not suddenly. The lubricating
ability of a grease (over time) depends primarily on the type of grease, the size of
the bearing, the speed at which the bearing operates and the severity of the operat-
ing conditions. Good results can be obtained if the following recommendations are
used in your maintenance program.
Type of Grease
A high grade ball or roller bearing grease should be used. Recommended greases
standard service conditions are: Shell Dolium R (Factory installed) or Chevron
SRI.
