Why is there excessive temperature rise in my Sumitomo Bevel BUDDYBOX 4?
- K
  Katherine RoachAug 15, 2025
  If the Sumitomo Engine experiences excessive temperature rise, it could be due to several reasons. It may be caused by an overload, in which case you should decrease the load to the specified value. Another potential cause is voltage drop or voltage rise, requiring you to contact the electric power company. High ambient temperature can also lead to this issue, suggesting the need to improve the ventilation method. Lastly, damaged bearings or gears could be the culprit, necessitating the return of the unit to the factory for servicing.

  Curtis HunterAug 26, 2025
  If your Sumitomo Engine output shaft turns without a load, it could be due to several reasons. The switch might have insufficient capacity, so replace it with a specified one. There might be an overload, in which case you should decrease the load to the specified value. The fuse might also have insufficient capacity, so replace it with a specified one. A voltage drop could also be the cause, so contact the electric power company. If the motor stator coil is short-circuited, return the unit to factory for servicing.

Why is my Sumitomo Engine experiencing oil leakage?
- D
  Daniel StoneAug 30, 2025
  If your Sumitomo Engine is leaking oil, it could be due to several reasons. The oil seal might be damaged, requiring you to return the unit to factory for servicing. Loose bolts could also be the cause, so tighten bolts correctly. Alternatively, the oil seal might be damaged, so replace the oil seal with a new one. Finally, there might be excessive oil/grease supply, so remove excess oil/grease.

  tina03Nov 18, 2025
  If your Sumitomo Engine motor will not operate under load, it could be due to several reasons. It may be due to a power failure, in which case you should contact the electric power company. It could also be a defective electric circuit, so check the circuit. Another possible cause is a blown fuse; replace the fuse with a new one. Alternatively, the protective device may be engaged, so disengage it. The load may be locking, so check the load and safety device. Poor switch contact can also be the cause, so adjust the contact area section. In case of disconnection of motor stator coil or broken bearing, return the unit to factory for servicing. Finally, if the 3-phase is functioning as single-phase, check the power supply with a voltmeter and inspect the motor, coil in the transformer, contac...

Why does my Sumitomo Bevel BUDDYBOX 4 have abnormal sound and vibration?
- M
  Melissa ShieldsNov 21, 2025
  If your Sumitomo Engine is making abnormal sounds or vibrations, it could stem from several issues. Dust or foreign matter might have entered the bearings, or the bearings themselves could be damaged, requiring you to return the unit to the factory for servicing. Another cause could be a damaged gear, also necessitating factory servicing. If the installation surface isn't flat, it can distort the housing; in this case, flatten the base or use shims for adjustment. Insufficient rigidity of the installation base can cause resonance, so reinforce the base to increase rigidity. Misalignment of the shaft with the driven machine can also cause this, so align the shaft centers. Finally, the vibration might be transmitted from the driven machine, so operate the gearmotor or reducer individually to...
