Warranty

See your sales contract for warranty coverage.
Documentation of storage maintenance, alignment
and regreasing may be required for certain warranty
considerations.

Receiving

Motors are shipped in first class condition. They have
been inspected and are skidded to prevent damage
from ordinary handling during shipment.
Inspect new motors for shipping invoice. Make the
examination before removing from cars or trucks. If
damage or indication of rough handling is evident, file
a claim with the carrier at once, and notify your
Siemens sales representative.
Remove only the shipping invoice. Do not remove
tags pertaining to lubrication, operation and storage
instructions. Read and follow all instructions to insure
that no damage to motor
condensation) and motor windings occurs during
storage.
Use care in handling.
otherwise 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

Dropping the motor or
temporary film of rust inhibiting oil or, when a motor is
supplied specifically with "provisions for oil mist
lubrication" (oil supply system furnished by the user),
the motor is shipped from the factory with grease in
the bearings.
When receiving a motor with sleeve bearings:
1. Remove shaft blocking materials.
2. Visually inspect bearing condition through sight
glass and bearing drain opening.
of
3. Check for moisture accumulation. Remove any
If 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
lubrication, disassemble the motor, and clean the
grease from bearings, end caps, and the bearing
housing cavities with a suitable solvent.
