should be energized at the voltage shown by the space heater nameplate attached to the
motor. Incandescent light bulbs can be placed within the motor to provide heat. However, if
used, they must not be allowed to come in contact with any parts of the motor because of the
concentrated hot spot that could result.
This motor has been provided with a shaft shipping brace or shipping bolt (normally painted
yellow) to prevent shaft movement during transit, it must be removed to allow shaft rotation
(refer to Before Initial Start-Up, Remove Shipping Packaging section). It is very important that
this brace be reinstalled exactly as it was originally, before the motor is moved from storage or
any time when the motor is being transported. This prevents axial rotor movement that might
damage the bearings.
Motors equipped with sleeve bearings are shipped from the factory with the bearing oil
reservoirs drained. In storage, the oil reservoirs should be properly filled to the center of the oil
level gage with a good grade of rust inhibiting oil (refer to the certified drawing for oil viscosity
and any special requirements). To keep the bearing journals well oiled and to prevent rusting,
the motor shaft should be rotated several revolutions every 2 weeks. While the shaft is rotating
it should be pushed to both extremes of the endplay to allow for oil flow over the entire length of
the journals.
