Resumen de diagnóstico

La hoja de la sierra comienza a girar inmediatamente al insertar el battery, o la sierra no se detiene al soltar el gatillo. Esto es un peligro crítico de seguridad que requiere atención inmediata.

Causas probables

  • Trigger or lock-off is jammed by debris
  • Trigger return spring or switch has failed
  • Control or wiring is shorted
  • Trigger has been taped, tied, or modified
  • Impact damage has distorted the handle or controls

Comprobaciones rápidas

  1. Battery insertion causes no start, the saw starts only by deliberate control input, and trigger release de-energizes it every time.

Vista previa de reparación

  1. Do not retest by holding, taping, or bypassing the lock-off or trigger; clean only loose dry debris around the external controls.
  2. With the battery removed, verify the trigger and lock-off return freely and the handle is not cracked or distorted; any sticking confirms stop-use.
  3. Have the switch, return mechanism, wiring, and control repaired by an authorized service provider, and return the saw only after a controlled function test.
  4. Keep the blade clear, release the trigger, and remove the battery immediately when it is safe; do not set the saw down with a moving blade.
