Know Your Air Compressor WARNING: RISK OF INJURY FROM LIFTING WHAT CAN HAPPEN • Serious injury can result from attempting to lift too heavy an object. HOW TO PREVENT IT • The compressor is too heavy to be lifted by one person. Obtain assistance from others before lifting. FEATURES AUTO (-) / OFF (O) SWITCH Place this switch (B) in the AUTO (-) position to provide automatic power to the pressure switch and OFF(O) to remove power at the end of each use.
English reaches cut-out pressure, the check valve closes, allowing air pressure to remain inside the air tank. automotive, and ARO. One hand push-to-connect operation makes connections simple and easy. AIR INTAKE FILTER The filter (A) is designed to clean air entering the A pump. To ensure the pump continually receives a clean, cool, and dry air supply the filter must always be clean and the filter intake must be free from obstructions.
4. 5. Plug the power cord into the correct branch circuit receptacle. Set the Auto/Off switch to AUTO (-). INSTALLATION Assembly (Fig. 1) Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged in transit, contact the carrier and complete a damage claim. Do this immediately because there are time limitations to damage claims.
English • 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. 2. The supply line should have the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on side of motor, for this information.
Electrical Code. • Circuit is not used to supply any other electrical needs. • Extension cords comply with specifications. • Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay fuse. NOTE: If compressor is connected to a circuit protected by fuses, use only time delay fuses. Time delay fuses should be marked “D” in Canada and “T” in the U.S.
English (Refer to Voltage and Circuit Protection paragraph in the installation section of this manual.) 4. Open the drain valve (counterclockwise) fully to permit air to escape and prevent air pressure build up in the air tank during the break-in period. 5. Move the Auto/Off switch to “Auto” position. The compressor will start. 6. Run the compressor for 30 minutes. Make sure the drain valve and all air lines are open so there is only a minimal air pressure build-up in tank.
FIG. 3 WARNING: Risk of bursting. If any unusual noise or vibration is noticed, stop the compressor immediately and have it checked by a trained service technician. Shut-down (Fig. 1) 1. Move Auto/Off switch to the OFF position. NOTE: If finished using compressor, follow Steps 2 - 6. 2. Pull the regulator knob 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.
English Change pump oil X **+ Oil leak inspection X Inspect drive belt X Check drive belt tension X X Check pulley/flywheel alignment Check for unusual noise/vibration X Check for air leaks X* Clean compressor exterior X Remove tank from service X++ * To check for air leaks apply a solution of soapy water around joints. While compressor is pumping to pressure and after pressure cuts out, look for air bubbles to form. ** The pump oil must be changed after the first 20 hours or operation.
5. Carefully lift out the air filter and screens. NOTE: The screen edges are sharp. 6. Place cleaned or new air filter between the screens and insert back into grooves. Refer to the Replacement Parts under Service. 7. Place the plate back onto the pump head, insert the screws and washers, tighten the screws. CAUTION: Risk of unsafe operation. Do not operate without air filter. WARNING: Risk of bursting. Water will condense in the air tank.
English 3. 4. tainer. Replace the oil drain plug (S) and tighten securely Slowly add compressor oil until it reaches the middle of the sight glass (T). NOTE: When filling the crankcase, the oil flows very slowly into the pump. If the oil is added too quickly, it will overflow and appear to be full. compressor is not in use. Do not use the unit with the shrouds or belt guard removed. Serious injury could occur from contact with moving parts. Hot surfaces. Risk of burn.
5. 6. 7. 8. Motor Pulley/Flywheel Alignment 9. NOTE: Once the motor pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16” (1.6 mm) to prevent excessive belt wear. The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16” (1.6 mm) to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps: 1.
sure relief tube nut at air tank. Carefully move pressure relief tube away from check valve. 5. Unscrew the check valve (turn counterclockwise) using a 7/8” open end wrench. NOTE the orientation for reassembly. 6. Using a screwdriver, carefully push the valve disc up and down. NOTE: The valve disc should move freely up and down on a spring which holds the valve disc in the closed position, if not the check valve needs to be cleaned or replaced. 7. Clean or replace the check valve.

GLOSSARY CFM: Cubic feet per minute. SCFM: Standard cubic feet per minute; a unit of measure of air delivery. PSI: Pounds per square inch; a unit of measure of pressure. Cut-in pressure: Factory set low pressure point that starts the compressor to repressurize the tank to a higher pressure. Cut-out pressure: Factory set high pressure point that stops the compressor from increasing the pressure in the tank above a certain level.
English Troubleshooting Guide This section provides a list of the more frequently encountered malfunctions, their causes and corrective actions. The operator or maintenance personnel can perform some corrective actions, and others may require the assistance of a qualified DeWALT technician or your dealer. Problem Code Air leaks ..................................................................................................................................... 1 Air leaks in air tank or at air tank welds..
Troubleshooting Codes POSSIBLE CAUSE POSSIBLE SOLUTION 1 Fittings are not tight Tighten fittings where air can be heard escaping. Check fittings with soapy water solution. DO NOT OVERTIGHTEN. 2 Defective air tank Air tank must be replaced. Do not repair the leak. WARNING: Risk of bursting. Do not drill into, weld or otherwise modify air tank or it will weaken. The air tank can rupture or explode. 3 Leaking seals Contact a DeWALT factory service center or a DeWALT authorized service center.
English CODE POSSIBLE CAUSE POSSIBLE SOLUTION 14 Belt to tight Check belt tension, see Adjusting Belt Tension under Maintenance. 15 Pulley misalignment See Motor Pulley/Flywheel Alignment under Maintenance. 16 Pump oil is low Add synthetic blend, non-detergent air compressor oil to pump. See Compressor Pump Oil under Maintenance. 17 Detergent type oil being used in pump Drain oil and refill pump with synthetic blend non-detergent air compressor oil.
CODE POSSIBLE SOLUTION 26 Low voltage/motor overload Check that power supply is adequate and that compressor is on a dedicated circuit. If using extension cord, try using without. If compressor is connected to a circut protected by a fuse, use dual element time delay fuses (Buss Fusetron type “T” only). 27 Restricted air passages Inspect and replace transfer tubes or check valve, as required. 28 Low voltage motor Furnish adequate powder. 29 Bad check valve Replace check valve.
