Possible Causes
Worn motor bearings, Broken or unbalanced fan blades, Foreign object inside motor fan chamber, Previous impact damage from dropping the tool
How to Fix / Troubleshooting
Safety first: Remove the battery immediately. Do not continue running the vacuum with grinding noises.
- Check for external causes: Remove the dust cup and filters and shake out any loose debris. Inspect the intake area for foreign objects.
- Gently rotate fan (if accessible): If you can see the fan through the intake, gently nudge it with a plastic tool. Any scraping or wobble indicates internal damage.
- Avoid further use: Running the vacuum with a damaged fan or bearings can cause catastrophic failure and injury.
- Service action: Replace the motor housing assembly. The fan and bearings are typically not serviceable separately on Makita cordless vacuums.
