How to Fix / Troubleshooting

Safety first: Remove the battery before opening the handle or switch area.

  • Step 1 – Check battery fit: Ensure the battery locks firmly and does not move when you wiggle it.
  • Step 2 – Test trigger: While holding the trigger, gently move it side to side. If the motor cuts in and out, the switch is likely worn.
  • Step 3 – Inspect wiring: If comfortable, open the handle and inspect the wires from the trigger to the main board for breaks or loose connectors.
  • Step 4 – Replace switch or harness: Install a new trigger/power switch assembly or wiring harness as needed.
