Be sure the weight of the reducer, based on the nameplate, drawing and catalog provided,
does not exceed the maximum rate assigned to the rings. Otherwise, the device may break
and damage the equipment.
If the reducer is packed in a wooden case, it may not be appropriate for a fork lift
transportation. Secure the package with belt straps if fork lifting is necessary.
When transporting the reducer, insert eyebolts in the casing tap holes and suspend with care.

Motor Installation
CAUTION
Take caution so that the oil seal is not damaged from preliminary installation.
Make sure to accurately center the motor shaft and reducer input shaft.
Make sure to grease keyed motor shafts.
Make sure to wipe off grease from round motor shafts.
Do not hit the reducer and the motor with a tool such as a hammer, or insert the motor by
tightening the bolts. Excessive force applied to the reducer and the motor may cause damage
to the bearings or produce a loud noise.
Be sure to tighten the bolts upon confirming that the motor is correctly installed.
3-1. Keyed Motor Shafts
(Sleeve Coupling Type)
(1)
Install the reducer so that the motor mounting surface faces up.
(2)
Wipe off dust, rust, and rust prevention oil from the motor shaft and reducer.
(3)
Grease the motor shaft to prevent burns.
(4)
Align the motor output shaft key with the reducer input hollow shaft keyway accurately.
(5)
Carefully insert the motor output shaft into the reducer input hollow shaft.
(6)
After verifying that the motor and reducer flange grooves are completely intact, secure the reducer
onto the motor flange by tightening appropriate bolts to their applicable torque.
a.
Greasing
The reducer input hollow shaft bore is factory greased to prevent burns. Apply some of this grease
to the motor shaft, and then mount the motor. If reassembling, use a molybdenum grease to
prevent burns.
b.
Installing a Key Sleeve Coupling
Slide a Key Sleeve coupling onto the motor shaft and secure by tightening the setscrews with a
hexagonal wrench. Then, mount the motor to the reducer.
