Common symptoms
- At no load the motor starts, but speed has a dead band, surges, cuts out, or ignores trigger pressure.
- With the bit removed, the driver makes continuous abnormal grinding, knocking, or scraping.
- With a charged pack installed and direction selected, the trigger produces no light, sound, or anvil movement.
- The direction button jams, will not hold center lock, or the tool runs in only one direction.
- The accessory catches or stops in the material and the tool reacts sharply in the hand.
- The trigger lights the work area, but the motor stays silent and the quick-release chuck does not turn.
- The trigger binds or does not spring fully OFF, or the motor keeps running after the trigger is released.
- The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
