How to Fix / Troubleshooting
Safety: Immediately release the trigger, remove the battery, and move the tool to a non-flammable area. Do not continue to operate.
- Inspect for blockages: Check hose, nozzle, and filters for severe clogs that could overload the motor.
- Smell test: If the burning smell is from the motor housing, the motor windings or brushes (if present) may be damaged.
- Check wiring: Open the housing and look for melted insulation or burnt connectors.
- Resolution: Replace the motor assembly and any damaged wiring harness. If the control PCB shows heat damage, replace it as well. Do not attempt to reuse a burnt motor.
