Installation Notes
Installation Precautions
• Do not use the reducer/gearmotor for specifications
other than those shown on the nameplate or in the
manufacturing specification documents . Personal injury
and/or equipment damage may occur .
• Do not place combustible material on or around the
unit; fire may occur .
• Do not place any objects around the unit that will
prohibit proper ventilation . Inadequate ventilation may
lead to high unit temperature and/or fire .
• Do not step on or hang from the unit . Excessive weight
may cause component breakage leading to personal
injury and/or equipment damage .
• Do not touch the shaft, keyway, or motor fan with bare
hands; injury may occur .
• For applications in which lubricant leaks could
adversely affect operations (i .e ., package handling,
food processing), place an oil pan below the unit to
protect against contamination that may occur if oil seals
become damaged or worn .
• Do not remove the eye-bolt from the motor . Should the
eye-bolt need to be removed for any reason, install a
replacement bolt in the tapped hole to prevent water
from entering the motor .

Consult Sumitomo when the unit will operate in conditions other than
those specified above . Special unit modifications may be required .
Units manufactured according to customer specified application
requirements (i .e . outdoor modifications, high-temperature
modifications) are designed to operate within the specified
environment .
Install the unit so inspection and/or maintenance procedures may
be easily performed . Install all units that are not shaft mounted on a
sufficiently rigid base .
Torque arm clearance with machine structure is required to allow for
machine shaft run out . Refer to the Torque Arm Installation section in
this manual for additional information .
Installation Angle
Mount the unit in the specified position,
Mixer Drive to be vertical
upright, shaft downward . Confirm the mounting position from the
gearbox nameplate .
Consult your local distributor, Original Equipment Manufacturer or
Sumitomo directly if the mounting angle is to be
other than vertical
upright .
In case a unit shipped with oil filled by Sumitomo, carefully handle
angle of unit because drywell device will be inside gearbox and which
should not be flooded by oil . If customer has to fill oil, it should be
after installation completed and until the level is fixed .
Severe Loading Conditions
For applications with severe vibration and/or frequent starts and
stops, Sumitomo recommends the use of high-strength mounting
bolts of Grade 8 .8 (or greater) . If customer has to fill oil, it should be
after installation completed and until the level is fixed .
Installation onto the Driven Machine
• Before coupling the reducer/gearmotor to the
machine, verify the appropriate/desired rotation of the machine .
Differences in the rotational direction may cause personal injury
and/or equipment damage .
• Before operating the unit, ensure that all safety guards around
the rotating components are in-place and secure . Failure to do
so may result in personal injury .
• When joining the reducer or gearmotor to the load, ensure that
the center alignment, belt tension, and/or parallelism of the
coupling device are within the coupling manufacturer’s established
recommendations . For applications with a belt, ensure that the
belt is properly tensioned to the manufacturer’s specification, and
the bolts securing the pulley and couplings are sufficiently tight-
ened . Failure to follow these precautions may result in personal
injury and/or equipment damage .
·
Taper Grip Busing, Easy Grip, and shrink disc are not for use in
applications where thrust load is transmitted to the reducer .
Friction locking devices are only for use where the mixing shaft
is supported by a thrust bearing .
