Introduction
This manual provides instructions for the safe and effective use of the DEWALT DWE575DC Circular Saw Dust Collection Adapter. This adapter is designed to connect your compatible DEWALT circular saw to a dust collection system, significantly reducing airborne dust during operation and promoting a cleaner work environment.
Safety Information
Always adhere to general safety practices when working with power tools and accessories. Failure to do so may result in serious injury or property damage.
- Always read and understand the instruction manual for your circular saw before installing or using this adapter.
- Wear appropriate personal protective equipment, including eye protection, hearing protection, and a dust mask, when operating power tools.
- Ensure the circular saw is disconnected from its power source (unplugged or battery removed) before attempting any installation, adjustment, or maintenance.
- Verify that all connections, including the adapter to the saw and the hose to the adapter, are secure before operation.
- Do not modify the adapter or use it for purposes other than its intended design.

Setup and Installation
The DWE575DC dust collection adapter is designed for DEWALT circular saw models DWE575 and DWE575SB. It has also been noted to fit models such as DCS570B, DCS575, DCS578, and DCS590.
- Prepare the Saw: Ensure your circular saw is disconnected from its power source (unplugged or battery removed) to prevent accidental startup.
- Identify Dust Port: Locate the existing dust port area on your circular saw.
- Attach Rear Half: Position the rear half of the adapter onto the saw's dust chute. Hook the notch on the adapter onto the bottom rear of the saw's dust chute as indicated in the saw's manual.
- Position Front Half: Place the front half of the adapter into position, aligning it with the rear half and the saw's dust chute.
- Secure with Screws: Align the two halves and secure them using the provided Phillips head screws. Apply firm pressure to bring the two halves together and close any small gaps as you tighten the screws. Note that one screw may be located in an area that requires an angled screwdriver or a long bit for easier access, especially with battery-powered saws. Do not overtighten to avoid cracking the plastic.
- Replace Lower Guard Lever (if necessary): The adapter includes a replacement lower guard lever that is offset to ensure proper clearance. Remove the original lower guard lever from your saw (typically using a T-25 Torx or slotted bit screwdriver) and install the new, offset lever. Some newer saw models, particularly 60V saws, may already feature an offset lever that does not require replacement.

Operating Instructions
Once the dust collection adapter is securely installed, you can connect it to your dust collection system.
- Connect Dust Hose: Attach a common 1-1/2 inch diameter dust collection hose to the adapter's port. The adapter is also compatible with DEWALT dust collection system adapters DWV9150 and DWV9100 for broader system integration.
- Ensure Secure Connection: Verify that the hose connection is tight and free of leaks to maximize dust extraction efficiency.
- Optimize Dust Collection: The adapter features a side port that allows dust to exit downwards if a vacuum is not connected. For enhanced dust collection when a vacuum is in use, consider temporarily covering this side port with tape to direct all airflow through the connected hose.
- Operate Saw: Always operate the circular saw according to its own instruction manual and all applicable safety guidelines.
Maintenance
Regular maintenance ensures optimal performance and longevity of your dust collection adapter.
- Inspection: Periodically inspect the dust collection adapter for any signs of damage, cracks, or excessive wear. Replace the adapter if it is damaged.
- Cleaning: After each use, clean the adapter and its port to prevent blockages from sawdust and debris. Use compressed air or a stiff brush to clear any obstructions.
- Fastener Check: Ensure all fastening screws remain tight. Retighten if necessary, but avoid overtightening.
