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
- The worklight and motor respond together and the blade accelerates smoothly with the blade clear of material.
维修预览
- After seeing the light-only response, release the trigger, remove the battery, and wait until every moving part is fully still.
- 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
- Install a known-good fully charged compatible pack and make one clear no-load start attempt without touching the blade lock.
- 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
