MOTOR LUBRICATION - Long time satisfactory operation of an electric motor depends in large
measure on proper lubrication of the bearings. The charts below show recommended grease qualities
and regreasing intervals for ball bearing motors. For additional information, refer to the motor
manufacturer’s instructions.
The following procedure should be used in regreasing:
1. Stop the unit.
2. Disconnect, tag and lockout the unit from the power supply.
3. Remove the relief plug and free hole of hardened grease.
4. Wipe lubrication fitting clean and add grease with a hand-operated grease gun.
5. Leave the relief plug temporarily off. Reconnect the unit and run for about 20 minutes to expel
the excess grease.
6. Stop the unit. Replace the relief plug.
7. Restart the unit.
WARNING
Rotating machinery can cause injury or death. Open main disconnect, tag and
lockout power supply to the starter before working on the electric motor.
