If your orbital polisher does not start or does not operate at all, please stop using the machine and take it to your nearest authorized service center for inspection and repair. Do not attempt to disassemble or repair the machine yourself unless you are qualified to do so.
For troubleshooting, the following components should be checked in the order below, starting with the most basic and common causes:
1. Power Cord and Plug
Check whether the power cord or plug is loose, damaged, cut, or otherwise defective. Make sure the plug is properly connected to the power supply and that there is no visible damage to the cable.
Solution:
If the power cord or plug is damaged, it should be replaced by a qualified technician with a suitable component of the correct specification.
2. Internal Wires
Check the internal wiring for loose connections, damaged wires, disconnected terminals, or signs of overheating.
Solution:
If any wire or terminal is loose or damaged, it should be properly reconnected or replaced by a qualified technician.
3. Speed Controller Assembly
Check whether the speed controller assembly is functioning correctly. A faulty speed controller may prevent the motor from starting or cause abnormal operation.
Solution:
If the speed controller assembly is defective, replace it with the correct specification.
4. Main Switch
Check whether the main switch is functioning properly and whether it can reliably turn the machine on and off.
Solution:
If the switch is damaged or does not operate correctly, it should be replaced with a suitable replacement part.
5. Armature
Check the armature for signs of burning, overheating, damaged commutator segments, or other abnormal conditions. A severely damaged armature may prevent the motor from starting.
Solution:
If the armature is burnt or seriously damaged, replace it with a new armature of the correct specification.
6. Stator
Finally, check the stator for signs of burning, overheating, or other damage. A damaged stator can prevent the motor from operating normally.
Solution:
If the stator is burnt or damaged, it should be replaced with a new stator of the correct specification.
Important:
Always disconnect the machine from the power supply before inspection or maintenance. Electrical components should only be checked, repaired, or replaced by a qualified technician. If the cause of the failure cannot be identified, please contact an authorized service center for professional assistance.
