Slide a charged DEWALT 18V XR Li-ion battery pack onto the tool's battery port until it clicks securely into place. - Using the 12V Car Power Adapter:
Open the side compartment on the inflator to access the 12V input port. Plug the provided 12V car power adapter into this port. Then, plug the other end of the adapter into your vehicle's 12V accessory outlet. Ensure your vehicle's engine is running for optimal performance. - Using the Optional 240V AC Adapter (Not Included):
If you have the optional 240V AC adapter (SKU N557515), plug it into the appropriate port on the inflator and then into a standard wall outlet.

4.2 Attaching Hoses and Nozzles
The inflator comes with both a high-pressure hose and a high-volume hose, along with various adapters.
- For High-Pressure Inflation: Connect the high-pressure hose to the designated high-pressure port on the inflator. Select the appropriate nozzle (e.g., Presta adapter, ball needle) and securely attach it to the end of the high-pressure hose.
- For High-Volume Inflation/Deflation: Connect the high-volume hose to the designated high-volume port. Attach the appropriate high-volume adapter for the item you wish to inflate or deflate.
Integrated storage is provided on the unit for the high-pressure adapter, Presta bike adapter, and ball needle.
5. Operating Instructions
5.1 High-Pressure Inflation (Tires, Balls)
- Ensure the inflator is connected to a power source (battery, 12V car adapter, or AC adapter).
- Attach the high-pressure hose and the correct nozzle to the item to be inflated (e.g., tire valve).
- Press the power button (⏻) to turn on the inflator. The digital display will illuminate.
- Use the +/- buttons to set the desired pressure. The display shows the target pressure. You can cycle through pressure units (PSI, Bar, kPa) using the unit selection button.
- Press the start/stop button (▶/❚❚) to begin inflation. The inflator will automatically stop once the set pressure is reached.
