How to Fix / Troubleshooting
Safety first: Remove the battery pack before prolonged inspection. Do not run the motor for long periods if the squeal is loud.
- 1. Check for blockages: Ensure filters and air paths are clear to reduce motor load.
- 2. Short test: Reinstall the battery and run the vacuum briefly to confirm the noise is from the motor, not the nozzle.
- 3. Avoid lubrication attempts: Do not attempt to oil the motor through vents; this can damage the motor and is unsafe.
- 4. Replace motor: Persistent squealing indicates bearing wear. The main suction motor assembly should be replaced by a technician.
