Function of the Dust Bag Assembly

The DeWalt 387111-00 Dust Bag Assembly collects sanding dust produced during operation. It helps to:

• Capture fine wood dust and sanding debris
• Improve visibility while sanding
• Reduce airborne dust particles
• Help keep the work area cleaner
• Support efficient dust extraction from the sander
• Restore the tool's original dust collection performance

Using a genuine OEM replacement dust bag helps ensure proper fit, reliable dust capture, and optimal sanding performance.

Common Signs Replacement Is Needed

Replace the dust bag assembly if you notice:

• Torn or punctured bag material
• Reduced dust collection performance
• Dust leaking from the bag
• Damaged or cracked connector
• Excessive clogging that cannot be cleaned
• Loose fit on the dust port

A damaged or worn dust bag can reduce dust collection efficiency, increase airborne dust, and create a messier work environment.

Installation & Service Notes

Disconnect the sander from the power source before performing any maintenance.

Remove the existing 387111-00 Dust Bag Assembly from the dust outlet and inspect the dust port for accumulated debris or damage. Clean the outlet if necessary before installing the replacement dust bag. Push the new assembly firmly onto the dust port until fully seated and verify it remains securely attached during operation.

Important: Always verify your tool model, type number, and original part number before ordering. Empty the dust bag regularly to maintain maximum airflow and dust collection efficiency. Use genuine OEM DeWalt replacement parts to ensure proper fit and dependable performance.

Maintenance Recommendations

• Empty the dust bag before it becomes completely full.
• Shake out or clean accumulated fine dust after each use.
• Inspect the bag regularly for tears or worn seams.
• Keep the dust port free of debris to maintain airflow.
• Replace damaged dust bags promptly for optimal dust collection.
• Use genuine OEM replacement parts to maintain factory fit, efficient dust capture, and long-term sander performance.
