WARNING: 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 installa-
tions, 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:
WHAT CAN HAPPEN HOW TO PREVENT IT
• Failure to properly drain condensed
water from air tank, causing rust and
thinning of the steel air tank.
• Drainairtankdailyoraftereachuse.Ifairtank
develops a leak, replace it immediately with a
new air tank or replace the entire compressor.
• Modificationsorattemptedrepairstothe
air tank.
• Neverdrillinto,weld,ormakeanymodifications
to the air tank or its attachments. Never
attempt to repair a damaged or leaking air
tank. Replace with a new air tank.
• Unauthorizedmodificationstothesafety
valve or any other components which
control air tank pressure.
• Theairtankisdesignedtowithstandspecific
operatingpressures.Nevermakeadjustments
or parts substitutions to alter the factory set
operating pressures.
Attachments & accessories:
• Exceeding the pressure rating of air
tools, spray guns, air operated acces-
sories, tires, and other inflatables can
cause them to explode or fly apart, and
couldresultinseriousinjury.
• Follow the equipment manufacturers
recommendation and never exceed the
maximum allowable pressure rating of
attachments. Never use compressor to
inflate smalllowpressure objects such as
children’s toys, footballs, basketballs, etc.
Tires:
• Over inflation of tires could result in
seriousinjuryandpropertydamage.
• 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.Adjustpressureregulatoron
air supply to no more than the rating of the
tire pressure. Add air in small increments and
frequently use the tire gauge to prevent over
inflation.
WARNING: RISK OF ELECTRICAL SHOCK
WHAT CAN HAPPEN HOW TO PREVENT IT
• Your air compressor is powered by
electricity. Like any other electrically
powered device, If it is not used properly
it may cause electric shock.
• Neveroperatethecompressoroutdoorswhen
it is raining or in wet conditions.
• Never operate compressor with protective
covers removed or damaged.
• Repairs attempted by unqualified
personnelcanresultinseriousinjuryor
death by electrocution.
• Anyelectricalwiringorrepairsrequiredonthis
product should be performed by a
DeWALT
factory service center or a
DeWALT authorized
service center in accordance with national
and local electrical codes.
• Electrical Grounding: Failure to provide
adequate grounding to this product
could result in serious injury or death
from electrocution. See Grounding
Instructions under Installation.
• Make certain that the electrical circuit to
which the compressor is connected provides
proper electrical grounding, correct voltage
and adequate fuse protection.
WARNING: RISK FROM FLYING OBJECTS
WHAT CAN HAPPEN HOW TO PREVENT IT
• Thecompressedairstreamcancause
soft tissue damage to exposed skin
and can propel dirt, chips, loose par-
ticles,andsmallobjectsathighspeed,
resulting in property damage or personal
injury.

accessories.
WARNING: RISK OF HOT SURFACES
WHAT CAN HAPPEN HOW TO PREVENT IT
• Touching exposed metal such as the
compressor head, engine head, engine
exhaust or outlet tubes, can result in
serious burns.
• Never touch any exposed metal parts on
compressor during or immediately after
operation. Compressor will remain hot for
several minutes after operation.
• Do not reach around protective shrouds or
attempt maintenance until unit has been
allowed to cool.
WARNING: RISK FROM MOVING PARTS
WHAT CAN HAPPEN HOW TO PREVENT IT
• Moving parts such as the pulley, fly-
wheel,andbeltcancauseseriousinjury
if they come into contact with you or
your clothing.

AUTO/OFF SWITCH
Place this switch (A) in the AUTO (I) position to provide automatic power to the pressure
switch and OFF (O) to remove power at the end of each use.
PRESSURE SWITCH
The pressure switch (I) automatically starts the motor when the air tank pressure drops below
the factory set cut-in pressure. It stops the motor when the air tank pressure reaches the
factory set cut-out pressure.
SAFETY VALVE
If the pressure switch does not shut off the air compressor at its cut-out pressure setting, the
safety valve (G) will protect against high pressure by popping out at its factory set pressure
(slightly higher than the pressure switch cut-out setting).
CHECK VALVE
Whentheaircompressorisoperating,thecheckvalve(F)isopen,allowingcompressedair
toentertheairtank.Whentheaircompressorreachescutoutpressure,thecheckvalve
closes, allowing air pressure to remain inside the air tank.
TANK PRESSURE GAUGE
The tank pressure gauge (B) indicates the reserve air pressure in the tank.
REGULATED PRESSURE GAUGE
The outlet pressure gauge (C) indicates the air pressure available at the outlet side of the
regulator. This pressure is controlled by the regulator.
REGULATOR
The regulator (D) controls the air pressure shown on the regulated pressure gauge. Pull the
knob out and turn clockwise to increase pressure and counterclockwise to decrease pres-
sure.Whenthedesiredpressureisreachedpushknobintolockinplace.Theregulated
pressure range is 7–150 psi.
WARNING: Risk of Bursting. Too much air pressure causes a hazardous risk of bursting.
Check the manufacturer’s maximum pressure rating for air tools and accessories. The regula-
tor outlet pressure must never exceed the maximum pressure rating.
UNIVERSAL QUICK CONNECT BODY
The universal quick connect body (E) accepts the three most popular styles of quick connect
plugs: Industrial, automotive, and ARO. One hand push-to-connect operation makes con-
nections simple and easy.
DRAIN VALVE
The drain valve (H) is located at the base of the air tank and is used to drain condensation at
the end of each use. See Draining Air Tank under Maintenance.
COOLING SYSTEM
This compressor contains an advanced design cooling system. It is normal for this fan to
blow air through the vent holes in large amounts. The cooling system is working when air is
expelled.
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.
