the base for lifting the complete assembly. Refer to the
certified drawings. Do not use the eyebolts on the unit if
the unit is attached to another piece of machinery or
gearbox, unless the drawings show they were designed
for lifting the assembly.
Storage
When the unit is not put to immediate use, store it in a
clean, dry and protected area. Do not store unit where it
would be subjected to corrosive atmospheres or high
levels of moisture, shock or vibration. Excessive moisture
content of the air is detrimental. Maintain the temperature
between 32º and 104ºF (0º and 40ºC).
If the storage period exceeds three months, or when the
unit must be stored in an unprotected area, special
storage procedures are required. Coat all external
unprotected machined surfaces with a rust preventive
solution. Cover the unit to protect it from dirt, moisture and
debris, but leave air openings at the bottom to permit air
circulation. Do not try to seal the unit in plastic wrapping
with a moisture absorbent, as the integrity of the seal
cannot be assured.
Use screens around openings to prevent rodents from
nesting inside. When the ambient temperature is not
controlled, install and energize space heaters to keep the
unit's temperature above freezing and always above the
dew point.
Long-time storage requires special attention to bearings
and lubricants. To minimize brinelling and rusting, rotate
shafts once every three months to redistribute the
lubricant and re-coat bearing surfaces. Mark the shaft to
stop in a different position each time. The bearing
chambers of grease lubricated machines are packed
with grease at assembly and should not require additional
grease unless unusually severe environmental conditions
exist. Refer to Section 6 for grease specifications and
procedure to follow if periodic greasing is necessary.
Consult the Service Department at the factory whenever
a question exists regarding long- time storage.
Placing unit into service after storage requires careful
inspection. Look for signs of damage and moisture.
Correct any deficiency observed. Check the insulation
resistance of the motor stator, clutch coil and brake coil (if
used), as described in Section 6. When storage exceeds
one year, add grease, as described in Section 6, before
starting. If storage was three years or longer, the bearings
should probably be replaced, or at least inspected.

CAUTION
: Lifting lugs are designed to handle the
weight of the unit and any accessory mounted on the
unit. Do not use these lugs to lift a unit attached to
other equipment.
CAUTION:
Do not apply power to the motor, clutch or
other electrical devices if moisture is detected. Dry
them thoroughly. Consult the factory or one of the
authorized service shops for assistance to dry out a
unit.
