General Inspection
Inspect the motor at regular intervals, approximately every 500 hours of operation or every three (3)
months, whichever occurs first. Keep the motor clean and the ventilation openings clear. The following
steps should be performed at each inspection:
1. Check that the motor is clean. Check that the interior and exterior of the motor 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 ventilated, over heating can occur and cause early
motor failure.
2. Check all electrical connectors to be sure that they are tight.
Lubrication and 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 operating conditions. Good results can be obtained if the following
recommendations are used in the maintenance program. Type of grease: A high grade ball or roller
bearing grease should be used.
Recommended grease for standard service conditions:
1. Polyrex EM (Exxon Mobil)
Equivalent and compatible greases include:
1. Texaco polystar
2. Rykon premium #2
3. Pennzoil pen 2 lube
4. Chevron SRI
Lubrication Procedure
Be sure that the grease you are adding to the motor is compatible with the grease already in the motor.
With Grease Outlet Plug
1. Clean all grease fittings.
2. Remove grease outlet plug.
3. Add the recommended amount of grease.
4. Re-install grease outlet plug.
Do not touch electrical connections before you first ensure that power has
been disconnected. Electrical shock can cause serious or fatal injury. Only
qualified personnel should attempt the installation, operation and maintenance
of this equipment.
To avoid damage to motor bearings, grease must be free of dirt.
