INSTALLING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in
hand when installing or disconnecting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 PSI (0 kPa).
2. Grasp the hose at the Quick Connect plug and push the plug
into the Quick Connect body (E). Coupler will snap into place.
3. Grasp the hose and pull to ensure coupler is seated.
DISCONNECTING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in
hand when installing or disconnecting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 PSI (0 kPa).
2. Pull coupler on Quick Connect body back to release Quick
Connect plug on hose.
Lubrication
AIR COMPRESSOR
Oilless air compressors are factory lubricated for life and do not
require any oil.
Compatibility
Air tools and accessories that are run off the compressor must be
compatible with petroleum based products. If you suspect that a
material is not compatible with petroleum products, an air line filter
for removal of moisture and oil vapor in compressed air is required.
NOTE: Always use an air line filter to remove moisture and oil vapor
when spraying paint.
Location
Locate the air compressor in a clean, dry, and well ventilated
area.
Located the air compressor at least 12" (30.5 cm) away from
the wall or other obstructions that will interfere with the flow of
air.
Locate the air compressor as close to the main power supply
as possible to avoid using long lengths of electrical wiring.
NOTE: Long lengths of electrical wiring could cause power
loss to the motor.
The air filter must be kept clear of obstructions which could
reduce air flow to the air compressor.

Wiring Instructions

WARNING: Improper electrical installation of this product
may void its warranty and your fire insurance. Have circuit wiring
performed by qualified personnel such as a licensed electrician
who is familiar with the current national electrical code and any
prevailing local electrical codes.
WARNING: Risk of electrical shock. Improper electrical
grounding can result in electrical shock. The wiring should be
done by a qualified electrician.
A qualified electrician needs to know the following before wiring:
1. If the amperage rating of the electrical box is adequate. Refer
to the Pump/Motor Specifications, in the parts manual, for
this information.
2. If the supply line has the same electrical characteristics
(voltage, cycle, phase) as the motor. Refer to the
Pump/Motor Specifications for this information.
NOTE: The wiring used must be rated for the motor voltage, plus
or minus 10%. Refer to local codes for recommended wire sizes,
correct wire size, and maximum wire run; undersized wire causes
high amp draw and overheating to the motor.

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.
