MOTOR LUBRICATION – Long time satisfactory op-
eration of an electric motor depends in large measure
on the bearings and timely lubrication. The following
charts show recommended grease qualities and re-
greasing intervals for motors supplied with ball bear-
ings. For additional information refer to the motor
manufacturers instructions.
The following procedure should be used in regreasing:
1.
Stop the unit.
2.
Disconnect, tag and lockout the unit from the pow-
er supply.
3.
Remove the relief plug and free the hole of hard-
ened grease.
4.
Wipe the 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.
Rotating machinery can cause injury
or death. Open main disconnect, tag
and lockout power supply to the start-
er before working on the electric mo-
tor.
