6. Manteniment
To ensure the longevity and efficient operation of your electric motor, regular maintenance of carbon brushes is recommended:
- Inspecció periòdica: Periodically check the carbon brushes for wear. They should be replaced when they are worn down to approximately one-third of their original length or if they show signs of chipping or cracking.

- Excés de guspires: While some initial sparking is normal, persistent heavy sparking can indicate worn brushes, a dirty or damaged commutator, or incorrect brush type/size. Disconnect power and inspect.
- Soroll inusual: Grinding or squealing noises may suggest improper brush seating or a damaged commutator.
8. Informació de seguretat
- Always disconnect the power supply to the motor or tool before attempting any inspection, maintenance, or replacement of carbon brushes.
