How to Fix / Troubleshooting

Safety first: Remove the battery before working on the trigger.

  • Clean around trigger: Use a dry cloth or compressed air to remove dust and debris from around the trigger area.
  • Check feel: The trigger should have a distinct click. If it feels mushy or inconsistent, the internal switch is worn.
  • Open handle (advanced): Remove screws and carefully open the handle housing. Inspect the trigger lever and microswitch for damage.
  • Replace switch or handle assembly: If the microswitch is faulty, replace it or the entire handle PCB/trigger assembly, depending on available parts.
  • Reassemble carefully: Ensure the trigger spring is correctly positioned and the housing closes without pinching wires.
