진단 개요

FM-20

예상 근본 원인

  • Collar is actually in drill mode or a high setting
  • Fastener, bit, or scrap material is unsuitable for the comparison
  • Clutch cam, spring, or detent is jammed
  • Gearbox or spindle bypasses the torque-limiting mechanism

빠른 점검

  1. The clutch ratchets before overdriving at an appropriate low setting, or the no-release fault is proven.

수리 미리보기

  1. Install a verified battery and drive slowly while holding the tool straight, stopping immediately if the fastener begins to overdrive without ratcheting.
  2. If several low settings never release under a valid comparison, remove the battery and route the clutch and gearbox to service.
  3. Remove the battery and set up a matching fastener and sound driver bit in suitable scrap material.
  4. Set the collar to a low numbered position, use range 1, and confirm the index is not on drill mode.
