How to Fix / Troubleshooting
Safety: Disconnect power before tightening or replacing components.
- Inspect mounts: Check that all motor and pump mounting bolts are tight. Replace any missing hardware.
- Check isolation mounts: Many Prochem units use rubber mounts to reduce vibration. Inspect for cracks or collapse and replace as needed.
- Inspect fan and brush: Look for damage to the vacuum fan or brush assembly. Replace any component that is bent, cracked, or missing pieces.
