WARNING: Some dust contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm such as asbestos and lead in lead based paint. Definitions: Safety Guidelines Save these instructionS DANGER: Risk of explosion or fire What can happen How to prevent it • It is normal for electrical • Always operate the comprescontacts within the motor sor in a well ventilated area and pressure switch to free of combustible materials, spark. gasoline, or solvent vapors.
English • Restricting any of the compressor ventilation openings will cause serious overheating and could cause fire. • Unattended operation of this product could result in personal injury or property damage. To reduce the risk of fire, do not allow the compressor to operate unattended. • Never place objects against or on top of compressor pump. • Operate compressor in an open area at least 12" (30.
• Modifications or attempted repairs to the air tank. What can happen • Failure to properly drain condensed water from air tank, causing rust and thinning of the steel air tank. • Unauthorized modifications to the safety valve or any other components which control air tank pressure.
English Tires: • Over inflation of tires could result in serious injury and property damage. • Repairs attempted by unqualified personnel can result in serious injury or death by electrocution. • Use a tire pressure gauge to check the tires pressure before each use and while inflating tires; see the tire sidewall for the correct tire pressure. NOTE: Air tanks, compressors and similar equipment used to inflate tires can fill small tires very rapidly.
WARNING: Risk from Moving Parts What can happen How to prevent it • Moving parts such as the • Never operate the compressor pulley, flywheel, and belt can with guards or covers which cause serious injury if they are damaged or removed. come into contact with you or • Keep your hair, clothing, and your clothing. gloves away from moving parts.

Never operate damage to the compressor compressor on a roof or and could result in serious other elevated position. Use injury or death to the additional air hose to reach operator. high locations.
SAVE THESE INSTRUCTIONS FOR FUTURE USE Features (Fig. 1) Tank Pressure Gauge The tank pressure gauge (K) indicates the reserve air pressure in the tank. Auto(–)/Off(o) Switch Place this switch (L) in the AUTO(–) position to provide automatic power to the pressure switch and OFF(O) to remove power at the end of each use. NOTE: ALWAYS ensure the switch (L) is in the OFF(O) position before removing or replacing pressure switch cover.
English Air Compressor Pump The pump compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet. AIR INTAKE FILTER The filter (J) is designed to clean air entering the 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.
for 115 volts and the rated amps of the compressor, See Motor Specifications. WARNING: Do not operate this unit until you read and understand this instruction manual for safety, operation and maintenance instructions. Grounding Instructions 230 Volt Conversion Warning: Risk of electrical shock. In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded.
English • Do not modify the plug provided. If it does not fit the available outlet, a correct outlet should be installed by a qualified electrician. • Repairs to the cord set or plug MUST be made by a qualified electrician. 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.
Transporting Lifting Always use two people when lifting and lift from the recommended lift points A and C. MOVING 1. Support compressor and pull handle (A) until fully extended (lock position). A A Warning: Risk of unsafe operation. Ensure proper footing and use caution when rolling compressor so that unit does not tip or cause loss of balance. 2. To move, roll compressor on tires using handle (A) as shown. Operating Procedures Start-up (Fig. 1) Warning: Hot surfaces. Risk of burn.
English the pump head. If compressor shuts off, contact a DeWALT service center or call 1‑800‑4‑DeWALT (1-800-433-9258) for assistance. Note: For proper operation the pilot valve blow-off pressure must be below the pressure switch cut out pressure. 4. Adjust regulator (F) to desired setting. See Regulator under Features. CAUTION: Risk of unsafe operation. Do not operate in vertical position. Vertical position is for storage only. CAUTION: Risk of unsafe operation.
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. Draining Air Tank (Fig. 1) Warning: Risk of unsafe operation.
English Service Information NOTICE: Risk of property damage. Drain water from air tank may contain oil and rust, which can cause stains. 6. When air tank pressure gauge reads 10 psi, rotate valve to the fully open position. 7. Close drain valve when finished.
