WARNING: RISK OF BURSTING
Air Tank: On February 26, 2002, the U.S. Consumer Product Safety
Commission published Release # 02-108 concerning air compres-
sor 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 modifica-
tions, 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 corro-
sion 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

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 accessories, tires,
and other inflatables can
cause them to explode or
fly apart, and could result in
seriousinjury.
• Followtheequipmentmanu-
facturers recommendation
and never exceed the maxi-
mum allowable pressure rat-
ing of attachments. Never use
compressor to inflate small
lowpressureobjectssuchas
children’s toys, footballs, bas-
ketballs, 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 frequent-
ly use the tire gauge to prevent
over inflation.

SAFETY VALVE
If the pressure switch does not shut off the air
G
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 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 (K) indi-
E
F
D
K
cates the reserve air pressure in
the tank.
REGULATED PRESSURE
GAUGE
The regulated pressure gauge (D) indicates the air pressure
available at the outlet side of the regulator. This pressure is
controlled by the regulator.
REGULATOR
The regulator (F) controls the air pressure shown on the regulated
pressure gauge. Pull the knob out and turn clockwise to increase
pressure and counterclockwise to decrease pressure. 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 regulator outlet
pressure must never exceed the maximum pressure rating.
UNIVERSAL QUICK CONNECT BODIES
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 connections simple and
easy. The two quick connect bodies allow the use of two tools at the
same time.
DRAIN VALVE
The drain valve (M) is located at the base of
M
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
J
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.
MOTOR OVERLOAD PROTECTOR
The motor has a thermal overload protector.
If the motor overheats for any reason, the overload protector will

WARNING: Risk of bursting. If the safety valve does not work
properly, over-pressurization may occur, causing air tank rupture or
an explosion.
WARNING: Risk from flying objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side
shields when using the compressor.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. Before starting
compressor, pull the ring on the safety valve to make sure that
the safety valve operates freely. NOTE: Ring may be difficult to
pull when air tank pressure is at 0 psi. If the valve is stuck or does
not operate smoothly, it must be replaced with the same type of
valve.

WARNING: Risk of unsafe operation. Risk from noise. Air tanks
contain high pressure air. Keep face and other body parts away from
outlet of drain. Use eye protection [ANSI Z87.1 (CAN/CSA Z94.3)]
when draining as debris can be kicked up into face.
WARNING: Risk from noise. Use ear protection [ANSI S12.6
(S3.19)] as air flow noise is loud when draining.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g. tanks, filter, aftercoolers, dryers).
This condensate contains lubricating oil and/or substances which
may be regulated and must be disposed of in accordance with local,
state, and federal laws and regulations.
1. Ensure Auto/Off switch is in the OFF position.
2. Lift compressor into an inclined position so drain valve (M) is at
the lowest point (this will assist in removing moisture, dirt, etc.
from air tanks).
3. Place a suitable container under the drain valve to catch
discharge.
4. Grasp lever on drain valve.
5. Slowly rotate lever to gradually bleed air from air tank.
WARNING: Risk of bursting. Drain air tank daily. Water will
condense in air tank. If not drained, water will corrode and weaken
the air tank causing a risk of air tank rupture.
NOTICE: Risk of property damage. Drain water from air tank may
contain oil and rust, which can cause stains.
6. When air tank pressure gauge reads 10 psi, rotate valve to the
fully open position.
7. Close drain valve when finished.

4. Remove element from filter base.
5. Place new element back in filter base. Purchase
replacement parts from your local dealer or
authorized service center. Always use identical
replacement parts.
6. Snap filter cover to filter base.
NOTICE: Risk of unsafe operation. Do not operate without air
inlet filter

CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
PSI: Pounds per square inch; a unit of measure of pressure.
kPa (kilopascal): Metric pressure measurement. 1 kilopascal equal 1000 pascals.

Cut-In Pressure: While the motor is off, air tank pressure drops when accessory is used. When the tank pressure drops to a certain low
level the motor will restart automatically. The low pressure at which the motor automatically restarts is called cut-in pressure.
Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a
certain high pressure before the motor automatically shuts off, protecting your air tank from pressure higher than its capacity. The high
pressure at which the motor shuts off is called cut-out pressure.
Branch Circuit: The circuit carrying electricity from electrical panel to outlet.
Duty Cycle: This air compressor pump is capable of running continuously. However, to prolong the life of your air compressor, it is
recommended that a 50%-75% average duty cycle be maintained; that is, the air compressor pump should not run more than 30-45 minutes
in any given hour.
