vice center.
Operate safety valve manually by pulling on ring. If valve still leaks, it
must be replaced.
Decrease amount of air usage.
Check the accessory air requirement. If it is higher than the SCFM
or pressure supplied by your air compressor, a larger compressor is
needed to operate accessory.
Check and replace air hose, if required.
Move unit to a dry well ventilated area.
Clean or replace air intake filter.
Run unit for longer duty cycles. It is recommended to run at high throttle
50-75% of the run time and idle for 25% of the run time.

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.
