WARNING: Risk of unsafe operation. Unit cycles automati-
cally when power is on. When performing maintenance, you
may be exposed to voltage sources, compressed air, or moving
parts. Personal injuries can occur. Before performing any main-
tenance or repair, disconnect power source from the compres-
sor and bleed off all air pressure.
To ensure efficient operation and longer life of the air compressor
outfit, a routine maintenance schedule should be prepared and fol-
lowed. The routine maintenance schedule (shown above) is geared
to an outfit in a normal working environment operating on a daily
basis. If necessary, the schedule should be modified to suit the con-

ditions under which your compressor is used. The modifications
will depend upon the hours of operation and the working environ-
ment. Compressor outfits in an extremely dirty and/or hostile envi-
ronment will require a greater frequency of all maintenance checks.
NOTE: See OPERATION section for the location of controls.
Checking Safety Valve
WARNING: Hot surfaces. Risk of burn. Tubes, pump head,
and surrounding parts are very hot, do not touch. Allow
compressor to cool prior to servicing.
WARNING: Risk of bursting. If the safety valve does not
work properly, over-pressurization may occur, causing air tank
rupture or an explosion.
WARNING: Risk from flying objects. Always wear certified
safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3)
with side shields.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. If the valve is
stuck or does not operate smoothly, it must be replaced with the
same type of valve.
Checking Air Filter
WARNING: Hot surfaces. Risk of burn. Tubes, pump head, and
surrounding parts are very hot, do not touch. Allow compressor
to cool prior to servicing.
1. Ensure motor Auto/Off switch switch is in the
"Off (O)" position.
2. Allow unit to cool.
3. Remove filter (A).

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.
