imposing shock loads can cause unseen and undetected
damage to bearings. This damage such as false brinelling
of the races of anti-friction bearings can result in early
bearing failure.
If supplied, energize space heaters to help prevent
condensation within the motor enclosure.
Motors having sleeve bearings or oil lubricated antifriction
bearings are shipped WITHOUT OIL in the bearing
reservoir. These bearings and journal surfaces are
protected during shipment by a temporary film of rust
inhibiting oil or, when a motor is supplied specifically with
"provisions for oil mist
furnished by the user), the motor is shipped from the factory
with grease in the bearings.

(oil supply system
When receiving a motor with sleeve bearings:
1. Remove shaft blocking materials.
2. Visually inspect bearing condition through sight glass
and bearing drain opening.
3. Check for moisture accumulation. Remove any traces
of oxidation before putting the motor into service.
4. Fill bearing reservoirs to normal level with a high grade
industrial lubricating oil. See Maintenance Section of
this instruction book to determine proper oil level.
5. Rotate the shaft a minimum of 10 complete turns by
hand to distribute oil over bearing parts. Make sure the
oil rings in each bearing rotate freely.
When receiving a motor with grease lubricated anti-
friction bearings:
Motors having grease lubricated antifriction bearings are
shipped with the bearings already lubricated and ready for
operation.
If the elapsed time from the time of shipment to the time in
which the unit is to be started is in excess of three (3)
months, regrease per the lubrication plate mounted on the
motor.
When receiving a motor with oil mist lubricated anti-
friction bearings:
1. Be sure that the motor is not stored outdoors.
2. Be sure that the oil mist lubrication is connected and
operating before starting the motor.
3. The oil mist lubrication should be in operation within two
weeks after the motor is received from the factory.
When receiving a motor with "provisions for oil mist
lubrication":
1. Leave the grease in the bearings if the motor is to be
stored.
2. Before operating the motor with oil mist lubrication,
disassemble the motor, and clean the grease from
bearings, end caps, and the bearing housing cavities
with a suitable solvent.
Heavy equipment.
Improper handling may cause death, serious injury or property
damage.
Check lifting devices before lifting. Use proper slings, chains
and spreaders.
Note any warning plates on motor and follow instructions on
each plate.
