4.Open the valve from below, keeping hands away from hot components.
5.Slowly rotate the lever or turn knob counter clockwise to gradually bleed air from tank.
6.When tank is at 10 PSI, rotate the lever or knob to the fully open position.
7.Close the drain valve when finished.
Preparation For Use
INITIAL SET-UP
Read all safety instructions before
1.Remove oil plug.
2.Pour DEWALT synthetic oil into crankcase (See Specifications).
WARNING: THE COMPRESSOR IS SHIPPED WITHOUT OIL IN THE CRANKCASE. ADD OIL.
3.Insert dipstick.
4.Close air tank drain valve.
CAUTION: Do not operate without lubricant or with inadequate lubricant. DEWALT is not responsible for compressor failure caused by inadequate lubrication.
Compatibility
Air tools and accessories that are operated with the compressor must be compatible with petroleum based products. If you suspect that a material is not compatible with petroleum products, use an air line filter for removal of moisture and oil vapor in compressed air. NOTE: Always use an air line filter to remove moisture and oil vapor when spraying paint.
Location
CAUTION: In order to avoid damaging the air compressor, do not allow the unit to be tilted more than 10˚ from the normal horizontal position when operating.
All hand carry compressors should be run with the rubber feet resting on a horizontal, flat surface.
Place the air compressor at least 3 feet away from obstacles that may prevent proper ventilation. Keep the compressor away from areas that have dirt and/or volatile fumes in the atmosphere. These impurities may clog the intake filter and valves, causing inefficient operation.
NOTE: The D55155 single tank air compressor is designed to be carried in the vertical orientation but will right itself in the proper horizontal position when placed on a flat surface.
HUMID AREAS
In frequently humid areas, moisture may form in the bare pump and produce sludge in the lubricant, 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. Two signs of excessive humidity are external condensation on the bare pump when it cools down and a “milky” appearance in compressor lubricant. You may be able to prevent moisture from forming in the bare pump by increasing ventilation or operating for longer intervals.
ELECTRICAL
Refer to the safety instructions before using unit. Observe extension cord safety instructions if necessary. Always shut off the air com- pressor switch before removing the plug from the outlet.
NOISE CONSIDERATIONS
Consult local officials for information regarding acceptable noise levels in your area. To reduce excessive noise, use vibration mounts or silencers, relocate the unit or construct total enclosures or baffle walls. Contact a DEWALT service center or call
