4. Operating Instructions
4.1 Powering On and Initial Pressure Build-up
- With the battery installed and hose connected, turn the power switch to the "ON" position.
- The compressor will begin to build pressure in the tank. This process may take a few minutes.
- The tank pressure gauge will indicate the current pressure. The compressor will automatically shut off once maximum pressure is reached.
4.2 Adjusting Output Pressure (OneTurn™ Regulator)
The OneTurn™ Regulator simplifies pressure adjustments for various tools.
- Consult your pneumatic tool's manual for its recommended operating pressure.
- Turn the large OneTurn™ Regulator dial to set the desired output pressure. The regulator gauge will display the set pressure.
- The compressor will maintain this pressure as you work, cycling on and off as needed.

4.3 Using Pneumatic Tools
Once the desired pressure is set, you can operate your pneumatic tools. The compressor provides 1.0 SCFM at 90 PSI, suitable for various applications such as nailing.
- For optimal performance, ensure your tool's air consumption does not exceed the compressor's output capacity.
- The compressor is capable of driving up to 970 nails per charge with a compatible battery.

4.4 Shutting Down
When finished, turn the power switch to the "OFF" position. Disconnect the air hose and release any remaining pressure in the tank by opening the drain valve or briefly activating a connected tool.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your air compressor. Always disconnect the battery before performing any maintenance.
5.1 Oil-Free Pump
This compressor features a heavy-duty oil-free pump, eliminating the need for oil changes and reducing maintenance requirements.
5.2 Draining the Air Tank
Moisture can accumulate in the air tank, leading to corrosion. Drain the tank after each use or at least daily if used frequently.
- Turn off the compressor and remove the battery.
- Place a suitable container under the drain valve located at the bottom of the tank.
- Open the drain valve slowly to release air and moisture.
- Close the drain valve once all pressure and moisture have been expelled.
5.3 Cleaning and Storage
- Clean the exterior of the compressor with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Store the compressor in a clean, dry location, out of reach of children and unauthorized users.
- The heavy-duty roll cage design helps protect critical components during transport and storage.
6. Troubleshooting
This section addresses common issues you might encounter with your air compressor.
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not start. | Battery not inserted correctly or discharged. | Ensure battery is fully charged and properly seated. |
| Compressor runs but does not build pressure. | Air leak in hose or connections; drain valve open. | Check all connections for tightness. Ensure drain valve is fully closed. |
| Pressure drops quickly when not in use. | Internal air leak (e.g., check valve). | Inspect for leaks. If persistent, contact DEWALT service. (Note: A slight pressure drop over extended periods is normal). |
| Compressor is excessively loud. | Normal operation for air compressors; loose components. | Wear hearing protection. Check for any loose parts and tighten if necessary. |
| Short battery runtime. | Battery not fully charged; heavy usage; aging battery. | Ensure battery is fully charged. Consider using a higher capacity battery or having a spare. |
