Vacuum cannot pick up fine dust effectively; filters clog almost immediately.

Safety first: Remove the battery before servicing filters.

• Verify filter setup: Ensure the pre-filter is installed and not torn. Replace if damaged.
• Clean filters frequently: When vacuuming fine dust, stop often to tap out the pre-filter and main filter to maintain airflow.
• Use appropriate equipment: For large amounts of fine construction dust, use a Makita vacuum designed for that purpose (e.g., with approved dust class and filter system).
• Inspect cyclone: Make sure the cyclone assembly is clean and correctly installed to separate fine dust before it reaches the filter.
