DANGER: RISK OF BURSTING
Air Tank: On February 26, 2002, the U.S. Consumer Product Safety
Commission published Release # 02-108 concerning air compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life is
dependent upon several factors, some of which include operating
conditions, ambient conditions, proper installations, field modifications, and the level of maintenance. The exact effect of these factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the inner wall of the air receiver tank can cause the air tank
to unexpectedly rupture allowing pressurized air to suddenly and
forcefully escape, posing risk of injury to consumers.
Your compressor air tank must be removed from service by the end
of the year shown on your tank warning label.
The following conditions could lead to a weakening of the air tank,
and result in a violent air tank explosion:

vibration pads and into the anchors.
7. Torque 3/8” lag screws to 7-10 ft.-lbs (9.5-13.5 Nm).
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. Two signs of excessive humidity are external
condensation on the pump when it cools down and a “milky”
appearance in compressor oil. You may be able to prevent
moisture from forming in the pump by increasing ventilation or
operating for longer intervals.
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 1-888-895-4549 for assistance.
Wiring Instructions
Anchoring of the Air Compressor
WARNING: Improper electrical installation of this product
may void its warranty and your fire insurance. Have circuit wiring
performed by qualified personnel such as a licensed electrician
who is familiar with the current national electrical code and any
prevailing local electrical codes.
WARNING: Risk of bursting. Excessive vibration can weaken the
air tank and cause an explosion. The compressor must be properly
mounted.
The air compressor MUST be bolted to a level, solid concrete
surface. Use 3/8” lag screws, vibration pads and concrete
anchors. If help is needed anchoring the air compressor consult
a licensed contractor.
1. Place the air compressor on a level, solid concrete surface.
Make sure the concrete is in good condition with no cracks
or damage.
WARNING:
Risk of electrical shock. Improper electrical
grounding can result in electrical shock. The wiring should be done
by a qualified electrician.
A qualified electrician needs to knows the following before wiring:
1. The amperage rating of the electrical box should be adequate.
12
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. When
turned OFF, the main power disconnect switch shuts off all power
to the compressor. When it is turned ON, the compressor will
start and stop automatically, controlled by the pressure switch.
WARNING: Risk of electrical shock. Electrical wiring must
be located away from hot surfaces such as manifold assembly,
compressor outlet tubes, heads, or cylinders.
Air Distribution System
Grounding Instructions
WARNING: Risk of bursting. Plastic or PVC pipe is not designed
for use with compressed air. Regardless of its indicated pressure
rating, plastic pipe can burst from air pressure. Use only metal pipe
for air distribution lines.
This product should be connected to a metallic, permanent wiring
system, of and equipment-grounding terminal or lead on the
product.
Voltage and Circuit Protection
INSTALLING AND DISCONNECTING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in hand
when installing or disconnecting to prevent hose whip. Ensure
regulated pressure gauge reads 0 psi.
Refer to the Voltage and Minimum Branch Circuit Requirements
under Specifications.
CAUTION: Certain air compressors can be operated on a

• Voltage supply to circuit must comply with the National
Electrical Code.
• Circuit is not used to supply any other electrical needs.
• Extension cords comply with specifications.
• Circuit is equipped with a 15 amp circuit breaker or 15 amp
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.
The next figure represents a typical air distribution system.
The following are tips to remember when setting up the air
compressor’s air distribution system.
NOTE: Compressed air from oil lube air compressors will contain
wa­ter condensation and oil mist. Several drains, traps and filters
will be needed to supply air without water (including aerosols) or oil
to spray equipment, air tools and accessories requiring filtered air.
Always read the in­struc­tions for the air tools and accessories being
used.
13
English
Refer to the Specifications, in the parts manual, for this
information.
2. The supply line should have the same electrical characteristics
(voltage, cycle, phase) as the motor. Refer to the motor
nameplate, on side of motor, for this information.
NOTE: The wiring used must be rated for the motor nameplate
voltage, plus or minus 10%. Refer to local codes for recommended
wire sizes, correct wire size, and maximum wire run; undersize wire
causes high amp draw and overheating to the motor.

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.
A flexible coupling is recommended to be installed between
the globe valve/air discharge outlet and main air distribution
line to allow for vibration.
A separate regulator is recommended to control the air
pressure. Air pressure from the tank is usually too high for
individual air driven tools.
DO NOT install lubricators between the tank and any spray
equipment, air tool or accessory requiring oil-free filtered air.
Drain all traps, filters and dirt legs daily.

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.
To ensure efficient operation and longer life of the air compressor
outfit, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to an
outfit in a normal working environment operating on a daily basis.
If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications will
depend upon the hours of operation and the working environment.
Compressor outfits in an extremely dirty and/or hostile environment
will require a greater frequency of all maintenance checks.
