Rotating machinery can cause injury or death. Open main disconnect, lockout
and tagout power supply to compressor package before working on the electric
motor.
Motor Lubrication - Long time satisfactory operation of an electric motor depends in large measure on
proper lubrication of the bearings. The following charts show recommended grease qualities and re-
greasing intervals for ball bearing motors. For additional information refer to the motor manufacturer’s
instructions. The following procedure should be used in re-greasing:
1. Disconnect, lockout and tagout power supply to the compressor package.
2. Wipe lubrication fitting clean and add grease with a hand-operated grease gun.
3. Wipe off only excess grease expelled by the automatic grease relief fitting supplied.
4. Restart the unit.
Main motors and aftercooler fan motor have automatic grease relief fittings.
