English 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, non-freezing area. MAINTENANCE The following procedures must be followed when maintenance or service is performed on the air compressor. 1. Ensure On/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.

If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture or an explosion. 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. To Drain Tank WARNING: Risk of Unsafe Operation. Risk from noise. Air tanks contain high pressure air. Keep face and other body parts away from outlet of drain. Use ANSI Z87.1 eye protection (CAN/CSA Z94.3) when draining as debris can be kicked up into face. WARNING: Risk from noise. Use ear protection [(ANSI S12.6 (S3.19) hearing protection] as air flow noise is loud when draining. NOTE: All compressed air systems generate condensate that accumulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). This condensate contains lubricating oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations. 1. Ensure On/Off switch (A) is in the OFF position. 2. Turn the regulator knob counter-clockwise to set the outlet pressure to zero. 3. Remove the air tool or accessory. 4. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring. 5. Drain water from air tank by opening drain valve (G) on bottom of tank. WARNING: Risk of Bursting. Water will condense in the air tank. If not drained, water will corrode and weaken the air tank causing a 13
