Maintenance

Carbon Brush Replacement

The carbon brushes play a crucial role in electrical conduction within the motor. Over time, carbon brushes will wear out due to friction, which can cause the motor to stop working. Regular inspection and replacement of carbon brushes are essential to prolong the service life of the motor.

• Always unplug the tool before attempting to replace carbon brushes.
• Locate the carbon brush caps on the sides of the tool housing.
• Unscrew the caps and carefully remove the old carbon brushes.
• Insert new carbon brushes, ensuring they are oriented correctly.
• Securely screw the caps back into place.

General Cleaning

Keep the tool's ventilation openings clean and free from dust and debris to ensure proper cooling and prevent overheating. Use a soft, dry cloth to clean the exterior of the tool. Do not use harsh chemicals or abrasive cleaners.
