How to Fix / Troubleshooting

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

Steps:

  • Clean around trigger: Use a soft brush or compressed air to remove dust and debris from the trigger area.
  • Lubricate lightly: Apply a very small amount of dry silicone spray to the trigger pivot (avoid overspray into electronics). Do not use oil-based lubricants that attract dust.
  • Check movement: Ensure the trigger moves freely and returns fully when released.

If the trigger remains stiff or fails to actuate the switch reliably, the trigger assembly may need replacement, which usually requires disassembling the handle.
