VII. FAILURE
VIII. REPAIR
Repairs should be made only by qualified personnel using the materials and processes for
which the motor was designed. To protect the warranty during the warranty period, all repairs
must be made in a GE Service Shop or GE approved repair facility. Many repairs can be easily
performed with only assembly operations if GE replacement parts are available. If major repairs
are undertaken (such as rewinding a stator), proper facilities should be available and suitable
precautions observed.
IX. RENEWAL PARTS
The use of only GE renewal parts is recommended. When ordering, specify the model number
and serial number of the motor (complete nameplate data is desirable). Specify quantity and
describe the part.
For information and service, refer to the nearest GE Sales Office or GE Authorized Service Shop
Warning
An extreme overload or electrical failure may result in heating or arcing which can cause the
insulation to give off noxious fumes. All power should be removed from the motor circuit as a
precaution even though the circuit has overload protection. Personnel should not approach
the motor until adequate ventilation of the area has purged the air of fumes. When covers of a motor are
removed after a failure, care should be observed to avoid breathing fumes from inside the motor. Preferably,
time should be allowed for the motor or to cool before attempting any examination or repair.
Failure to observe these precautions may result in injury to personnel.
Warning
Water should not be applied to any electrically energized equipment because electric shock
could result in serious or fatal injury. In case of fire, disconnect all power and use a carbon
dioxide extinguisher to quench the flame.
Before operating any motor after a suspected failure, it should be inspected for damage.
Warning
When burning off old insulation materials or when welding near insulation during re-winding,
adequate ventilation must be provided to avoid exposing personnel to noxious fumes.
Combustion of exhaust must be complete and adequately vented to the outside atmosphere in
compliance with acceptable standards.
Exposure of personnel to air-borne inorganic fibers must be avoided by adequate ventilation or by wetting
the remaining insulation components following the burning off of the organic materials.
Failure to observe these precautions may result in injury to personnel.
