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.

FeatureS (FIG. 1)
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 cut­out 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.
