Questions and answers
I just purchased a Dewalt dxcmsac260 and whan it shuts off a valve opens and it start releasing the air pressure. it's the same valve that opens when I put the compressor in the off position. what can I do to stop this?
To stop the air pressure release from the valve when the DeWalt DXCMSAC260 shuts off, follow these steps:
1. Inspect for Leaks – Visually check air lines and fittings for any leaks.
2. Check the Safety Valve – Manually operate the safety valve by pulling on the ring. If it continues to leak, replace it.
3. Ensure Proper Shut-Off – Turn the Auto/Off switch to the "Off (O)" position.
4. Verify the Drain Valve – Ensure the drain valve is fully closed.
5. Check for Excessive Air Usage – Reduce air consumption if the compressor is overused.
6. Inspect the Hose – Look for any holes or damage in the hose and replace it if necessary.
7. Clean or Replace the Air Filter – If the intake filter is clogged, clean or replace it.
If the issue persists, contact a DeWalt service center.
