FM-04: GERGAJI MULAI SAAT BATTERY DIPASANG ATAU TIDAK BERHENTI

Bilah gergaji mulai berputar segera saat battery dipasang, atau gergaji tidak berhenti berputar saat pemicu dilepaskan. Ini adalah bahaya keselamatan kritis yang memerlukan perhatian segera.

Diagnostic overview

Bilah gergaji mulai berputar segera saat battery dipasang, atau gergaji tidak berhenti berputar saat pemicu dilepaskan. Ini adalah bahaya keselamatan kritis yang memerlukan perhatian segera.

Likely Root Causes

  • 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

Quick Checks

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

Repair Preview

  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.
