2.Pull the regulator knob (D) out and turn counterclockwise until fully closed. Ensure regulated pressure gauge reads 0 psi. Push knob in to lock in place.
3.Remove hose and accessory.
Warning: Risk of unsafe operation. Firmly grasp air hose in hand when installing or disconnecting to prevent hose whip.
4.Drain the air tank, see Draining Air Tank under Maintenance. Ensure air tank pressure gauge reads 0 psi.
Warning: Risk of bursting. Drain air tank daily. Water will condense in air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture.
5.Allow the compressor to cool down.
6.Wipe air compressor clean and store in a safe,
Maintenance
The following procedures must be followed when maintenance or service is performed on the air compressor.
1.Ensure Auto/Off switch is in the OFF position.
2.Remove air compressor plug from outlet.
3.Drain air tank.
4.Allow air compressor to cool down before starting service.
NOTE: All compressed air systems contain maintenance parts (e.g., oil, filters, separators) that are periodically replaced. These used parts may contain substances that are regulated and must be disposed of in accordance with local, state, and federal laws and regulations.
NOTE: Take note of the positions and locations of parts during disassembly to make reassembly easier.
NOTE: Any service operations not included in this section should be performed by a DeWALT factory service center or a DeWALT authorized service center.

Checking Safety Valve |
|
Warning: Risk of bursting. If the safety valve does not work properly,
Warning: Risk from flying objects. Always wear certified safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields when using the compressor.
Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. NOTE: Ring may be difficult to pull when air tank pressure is at 0 psi. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve.
