Vacuum leaves fine dust on surfaces and exhaust air seems dusty.

Safety first: Remove the battery and avoid inhaling dust during service.

• 1. Verify filter type: For fine dust (e.g., drywall), ensure you are using a Milwaukee HEPA or fine dust filter compatible with your model.
• 2. Clean or replace filter: Tap the filter gently to remove dust. If performance remains poor, replace the filter.
• 3. Check pre-filter: Some models use a foam pre-filter. Ensure it is present, clean, and correctly installed.
• 4. Seat filter correctly: Reinstall the filter, making sure it is fully engaged and sealed.
• 5. Avoid overfilling: Empty the canister before it reaches the max fill line to maintain filtration efficiency.
