English Introduction compressor during or immediately after operation. Compressor will remain hot for several minutes after operation. Do not move the compressor while it is running. Hot motor parts could cause burns contributing to the dropping of the compressor, damaging the compressor and/or injuring the operator. Congratulations on the purchase of your new DEWALT Air Compressor! You can be assured that this tool has been constructed with the highest level of precision and accuracy.
SAFETY RELIEF VALVE This valve (A) is designed to prevent system failures by relieving pressure from the system when the compressed air reaches a predetermined level. The valve is preset by the manufacturer and must not be removed or modified in any way. AIR INTAKE FILTER(S) The filter(s) (B) are designed to clean air entering the pump. To ensure the pump continually receives a clean, cool, and dry air supply the filter(s) must always be clean and the filter intake must be free from obstructions.
English CHECKING SAFETY RELIEF VALVE OPERATION WARNING: Aftercooler, pump head, and surrounding parts are very hot, do not touch. (see the Hot Surfaces identified on page 2) 1. Ensure unit is off. 2. Ensure tanks are empty by looking at tank pressure gage. Drain tanks if necessary. 3. Grasp wire ring on safety valve. 4. Pull and release ring a few times to ensure plunger moves in and out. WARNING - Moving Parts: Keep your hair, clothing and gloves away from moving parts.
INSTALLING HOSES WARNING: Firmly grasp hose in hand M when installing or disconnecting to prevent L hose whip. 1. Ensure regulated pressure gage reads 0 PSI. 2. Grasp hose in hand at coupler location. 3. Pull back collar on female quick connect coupler (M) located on compressor. 4. Push male connector into female connector. 5. Release female connector 6. Grasp hose and pull to ensure couplers are seated 7. Adjust regulator to desired pressure.
English Location MOVING: When moving the unit into a position for use, grasp handle grips at rear of compressor, and lift compressor high enough so unit can be rolled on the front tire. WARNING: Ensure proper footing and use caution when rolling compressor so that unit does not tip or cause loss of balance. CAUTION: In order to avoid damaging the air compressor, do not allow the unit to be tilted more than 10˚ when operating.
Operating Procedures SHUT-DOWN 1. Follow the “Stopping the Engine” procedures in engine owner’s manual. NOTE: If finished using compressor, follow steps 2 - 6 below. 2. Turn regulator knob counterclockwise until fully closed. Ensure regulated pressure gage reads 0 PSI. 3. Remove hose and accessory. 4. Drain the air tank(s). Ensure tank pressure gage reads 0 PSI 5. Allow the compressor to cool down. 6. Wipe air compressor clean and store in a safe, non freezing area.
English MAINTENANCE CHART Procedure 3. 4. 5. 6. Locate a suitable container under drain plug (O). Remove the knurled filler knob (N) from crankcase. Remove the oil drain plug.
