How to Fix / Troubleshooting

Safety first: Remove the battery before manipulating the trigger.

  • 1. Inspect the trigger area: Look for visible debris or damage around the trigger. Gently clean with a soft brush.
  • 2. Test trigger movement: Squeeze and release the trigger. It should move smoothly and return under spring tension.
  • 3. Listen for switch click: With the battery removed, squeeze the trigger and listen for a faint click from the internal microswitch. No click suggests switch failure.

Repairing the trigger or switch usually requires disassembling the main body. Replace the trigger assembly or main body housing via a service centre if the trigger is broken or the switch has failed.
