Hazardous voltage. 

Will cause death, serious injury, 
electrocution or property damage. 

Disconnect all power before working on 
this equipment. 

 
These instructions present general recommendations 
for installation, operation and maintenance of 
induction motors built at the Norwood plant.  If 
additional information is required, contact Siemens 
Industry. 
 

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 bearings, (due to 
condensation) and motor windings occurs during 
storage. 
 
Use care in handling.  Dropping the motor or 
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  
 

 
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. 

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.
