诊断概览

拉动扳机激活工作灯,证明部分控制电源存在,但motor无声且锯片不旋转。

可能根本原因

  • Blade lock is stuck engaged or spindle is mechanically jammed
  • Lower guard, blade, or clamp stack is contacting another part
  • Trigger switch output, electronic module, motor, or internal wiring has failed
  • Battery can power the light but cannot supply motor current

快速检查

  1. The worklight and motor respond together and the blade accelerates smoothly with the blade clear of material.

维修预览

  1. After seeing the light-only response, release the trigger, remove the battery, and wait until every moving part is fully still.
  2. Check that the blade lock button returns, the blade is clamped correctly, the lower guard moves freely, and no debris or part is visibly jamming the blade
  3. Install a known-good fully charged compatible pack and make one clear no-load start attempt without touching the blade lock.
  4. If the light still responds but the motor remains silent, stop use and have the switch, module, motor, spindle, and internal wiring diagnosed by authorized
