10. Troubleshooting
When any abnomality occurs in the reducer, refer to the following table and take appropriate measures as soon as
possible. If they are not repairable, contact the nearest agent, distributor or service office.
Details of trouble
The input shaft rotates, but the output
shaft will not. Damage due to overloaded gears or
shafts
The key is out of position
Scorched bearing
Poor adjustment of protective device
Incorrect wiring for the motor
Overload
The ambient temperature is too high
Damage due to overload applied to
gears, bearings, etc.
Reduce the load to the specified value
Improve the ventilation method
Damaged gears, shafts, or bearings Repair at a specialized workshop
Deformation of the housing due to
irregular installation surface Flatten the installation surface or use
liners for adjustment
Repair at a specialized workshop
Damaged oil seal
Scratches or abrasion of the lip contact
section
Loose tightening bolt
Tighten the tightening bolts to the proper
torque
Change the oil seal

Oil leakage
Abnormal sound.
Excessively high vibration.
Oil leaks from the input /
output shaft sections.
Oil leaks from the joint
surface of the housing.
But it seizes up when a
load is applied.
Reverse rotation is possible.
Cause
Correction
Scorched bearing Repair at a specialized workshop
Resonance due to insufficient rigidity of
installation base Reinforce the installation base to
improve the rigidity
Incorrect alignment with the mating machine Align the shaft center
Transmission of the vibration of the
mating machine to the reducer Independently operate the reducer to
check the source of abnormal sound
