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 D
EWALT service center or call 1-800-4DEWALT for
assistance.
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 setting-up air compressor.
1. Remove oil plug.
2. Pour D
EWALT 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. D
EWALT 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.
