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.
To Adjust Regulator: 1. Pull regulator knob (E) out. 2. Turn knob clockwise to increase regulated pressure and counter-clockwise to decrease regulated pressure. 3. When desired pressure is shown on the regulated pressure gauge push knob in to lock. English reaches cut-out pressure, the check valve closes, allowing air pressure to remain inside the air tank. AIR INTAKE FILTER The filter (A) is designed to clean air entering the pump.
Set the Auto/Off switch to OFF (O). Allow the motor to cool. Depress the red reset button (M) on the motor. Set the Auto/Off switch to AUTO (-). 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. 2. Remove hose from air outlet (F). INSTALLATION Assembly (Fig. 1) Lubrication and Oil AIR COMPRESSOR The air compressor pump was filled WITH oil at the manufacturer.
English • The air filter must be kept clear of obstructions which could reduce air flow to the air compressor. 2. HUMID AREAS In frequently humid areas, moisture may form in the pump and produce sludge in the oil, causing running parts to wear out prematurely. Excessive moisture is especially likely to occur if the unit is located in an unheated area that is subject to large temperature changes.
If any of the above conditions cannot be met, or if operation of the compressor repeatedly causes interruption of the power, it may be necessary to operate it from a 20 amp circuit. It is not necessary to change the cord set. Main power disconnect switch Install a main power disconnect switch in the line from the panel to the compressor. The main power disconnect switch must be located near the compressor, for ease of use and safety.
English • • • • • • • Use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air. If piping is over 100’ (30.5 m) long, use the next larger size. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks.
manual for safety, operation and maintenance instructions. Break-in Procedure NOTICE: Risk of property damage. Serious damage may result if the following break-in instructions are not closely followed. The compressor is now ready for use. This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced. 1. Make sure the Auto/Off switch is in the “Off” position. 2. Check oil level in pump.
English tered air at an item that could be damaged by moisture. Some air tools and accessories may require filtered air. Read the instructions for the air tools and accessories. 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. How to Start 1. Turn the Auto/Off switch to “Auto” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure. 2.
X Inspect air filter Drain air tank 1 year or 200 Hours See tank warning label Monthly Daily Check safety valve 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 maintenance or repair, disconnect power source from the compressor and bleed off all air pressure.
English Checking Air Filter (Fig. 1) 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. Set the Auto/Off switch to “Off”. 2. Pull the regulator knob out and turn counterclockwise 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.
Checking 1. 2. Changing Q WARNING: Drain tank to release air pressure before removing the oil fill cap or oil drain plug. 1. 2. 3. 4. Remove the oil fill plug (Q). Remove the oil drain plug (R) and drain oil into a suitable container. Replace the oil drain plug (R) and tighten securely Slowly add compressor oil until it reaches the middle of the sight glass (S). NOTE: When filling the crankcase, the oil flows very slowly into the pump.

Troubleshooting Guide 25 English 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. Air leaks ..................................................................................................................................... 1 Air leaks in air tank or at air tank welds...........
English Troubleshooting Codes CODE 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.
CODE POSSIBLE SOLUTION 13 Carbon build-up in pump Contact a DeWALT factory service center or a DeWALT authorized service center. 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.
English CODE POSSIBLE CAUSE POSSIBLE SOLUTION 24 Damaged regulator Replace 25 Regulator open Roate the regulator knob counter-clockwise to its built-in stop and push knob in to lock in place. 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).
GLOSSARY NOTES English 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.
