Quick Checks

Repair Preview

  1. Turn the empty chuck slightly by hand while moving the selector gently into range 1 and then range 2.
  2. If it still will not reach both positions, keep the tool unpowered and route the selector fork or gearbox to service.
  3. Stop the chuck completely and remove the battery before touching the speed selector.
  4. Dry-clean around the selector and inspect the cap and housing for cracks, looseness, or obstruction.
