How to Fix / Troubleshooting

Safety first: Remove the battery before inspecting the handle and trigger.

  • 1. Check trigger feel: Squeeze the trigger or power lever repeatedly. It should move smoothly and spring back.
  • 2. Inspect for cracks: Look for visible cracks or looseness in the handle housing around the trigger.
  • 3. Test different angles: With the battery installed, gently move the vacuum while holding the trigger. If it cuts out at certain angles, internal wiring or the switch is likely loose.

Repair: Replacing the trigger switch or handle assembly requires opening the handle and soldering or reconnecting wires. This is best done by a qualified technician.
