FM-12 刀片BOLT或主轴锁无法操作

可能根本原因

  • Lock is not aligned with the spindle position
  • Left-hand bolt is being turned the wrong direction
  • Hex recess or wrench is rounded
  • Bolt, washer, or spindle threads are dirty or damaged
  • Spindle lock mechanism is broken

快速检查

  1. The spindle lock engages only while stopped, the bolt turns in the correct direction, and the blade clamps securely.

维修预览

  1. Clean the bolt, washer, and accessible spindle seating dry and inspect for cross-threading, cracks, burrs, or incorrect hardware.
  2. If the lock will not engage or the bolt is seized, stripped, or damaged, do not improvise leverage; have the spindle and hardware serviced.
  3. Remove the battery, use the supplied hex wrench, and press the spindle lock while rotating the blade by hand until the lock fully engages.
  4. Remember the left-hand thread: turn the blade bolt clockwise to loosen and counterclockwise to tighten; stop if the wrench or recess begins to round.
