Troubleshooting

Grinder won't turn on

Ensure the battery is fully charged and correctly inserted. Check if the battery is locked in place. Verify that the restart protection mechanism is not engaged.

Reduced cutting speed or power

Check the battery charge level; a low battery can cause reduced power. Ensure the disc is not dull or damaged and is correctly installed. Clean any dust or debris from the tool's ventilation slots.

Excessive vibration during operation

Verify that the disc is mounted correctly and is not damaged or warped. Ensure the locking nut is properly tightened. Check for any foreign objects or debris lodged in the tool.

Overload protection activated frequently

The tool may be under excessive load. Reduce the pressure applied during cutting or grinding. Ensure you are using the correct disc for the material. Allow the tool to cool if it has been running continuously under heavy load.
