For additional information refer to the motor manufacturer’s instructions. The following procedure should
be used in regreasing:
1. Stop the unit.
2. Disconnect lockout and tagout 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. Only enough grease
should be added to replace the grease used by the bearing. Too much grease can be as harmful as
insufficient grease. The grease cavity should be about 1/2 full.
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.
Rotating machinery can cause injury or death. Open main disconnect, lockout
and tagout power supply to starter before working on the electric motor.
