FM-21: KOPLING MELEPAS TERLALU AWAL ATAU MELUNCUR DALAM MODE BOR
FM-22
Diagnostic overview
FM-22
Likely Root Causes
- Numbered setting is too low for the fastener
- Collar is between detents or drill mode is not fully aligned
- Bit, fastener, or material is causing abnormal resistance
- Clutch spring, cam, gear, or drive interface is worn or broken
Quick Checks
- The clutch releases only at the selected driving torque and stays engaged in drill mode, or the early-release fault is proven.
Repair Preview
- Increase the numbered setting gradually for driving, or retest once in fully aligned drill mode without forcing the tool.
- If it still releases too early at suitable settings or slips in drill mode, route the clutch and gearbox to service.
- Release the trigger at early ratcheting, remove the battery, and verify the collar is fully aligned with a detent or drill mode.
- Fit a sound correct bit, secure suitable scrap material, and choose range 1 for driving or the proper range for drilling.
