Product Overview
The Festool 484727 Dust-Deflecting Brush Inserts are critical components for maintaining the dust extraction efficiency of your RAS 115 Sander. They are designed for easy replacement to ensure continuous high performance.
- Replacement dust-deflecting brushes for use with the RAS 115 Rotary Sander.

- Easy tool-less replacement.
- Includes 2 Brush Inserts.

Setup and Installation
Proper installation of the brush inserts is crucial for effective dust collection. These inserts are designed for tool-less replacement.
Installation Steps:
- Safety First: Ensure the Festool RAS 115 Sander is unplugged from the power source before attempting any installation or maintenance.
- Remove Old Brushes: Locate the existing dust-deflecting brush inserts on your RAS 115 Sander. Gently pull or slide out the worn brush inserts from their respective slots. They are designed to be removed without tools.
- Insert New Brushes: Take one of the new Festool 484727 brush inserts. Align it with the empty slot on the sander. The brushes should face outwards, ready to deflect dust.
- Secure in Place: Gently push the new brush insert into the slot until it clicks or sits firmly in place. Ensure it is fully seated and flush with the sander's housing.
- Repeat for Second Brush: If replacing both, repeat steps 3 and 4 for the second brush insert.
- Verify Installation: Once both inserts are in place, visually inspect them to ensure they are correctly positioned and secure.

Operation
Once installed, the Festool 484727 Dust-Deflecting Brush Inserts work automatically as part of the RAS 115 Sander's dust extraction system. They form a seal around the sanding pad, directing dust and debris into the integrated dust collection system or attached vacuum cleaner.
Ensure your dust extractor is properly connected and functioning for optimal performance. The brushes are designed to flex and adapt to the work surface, maximizing dust capture.
Maintenance
Regular maintenance of the brush inserts will prolong their lifespan and ensure consistent dust extraction performance.
- Cleaning: Periodically inspect the brushes for accumulated dust, debris, or hardened material. Use a soft brush or compressed air to gently clean the bristles. Avoid harsh chemicals that could damage the brush material.
- Inspection: Before each use, quickly inspect the brushes for signs of wear, such as flattened, bent, or missing bristles. Severely worn brushes will compromise dust extraction efficiency.
- Replacement: Replace the brush inserts when they show significant signs of wear, or if dust extraction performance noticeably declines despite proper cleaning. The "easy tool-less replacement" feature makes this a simple process.
