修理プレビュー

  1. Turn the sleeve by hand through a short open-close range while keeping fingers clear of the bit and jaws.
  2. If the sleeve or jaws remain seized, or the bit cannot be released safely, route the chuck and spindle lock to qualified service.
  3. Center the direction button, remove the battery, support the tool, and support any sharp or heavy bit so it cannot fall.
  4. Brush loose dry debris from the jaw openings and relieve any side load without striking, heating, oiling, or gripping the chuck with powered motion.
