I PORTANT SAFETY INSTRUCTIONS
RISK OF EXPLOSION OR FIRE
WHAT CAN HAPPEN
It is normal for electrical contacts within the motor and pressure
switch to spark.
If electrical sparks from the compressor come in contact with
flammable vapors, they may ignite, causing fire or explosion.
Restricting any of the compressor ventilation openings will
cause serious overheating and could cause fire.
HOW TO PREVENT IT
Always operate the compressor in a well ventilated area free of
combustible materials, gasoline or solvent vapors. If spraying
flammable materials, spray material at least 20 feet away from
the compressor. An additional length of hose may be required.
Store flammable materials in a secure location away from the
compressor.
Never place objects against or on top of the compressor. Oper-
ate compressor in an open area at least 18 inches away from
any wall or obstruction that would restrict the flow of fresh air to
the ventilation openings.
Operate compressor in a clean, dry and well ventilated area.
RISK OF BURSTING
WHAT CAN HAPPEN
1. Modifications or attempted repairs to the tank.
2. Unauthorized modifications to the unloader valve, safety
valve or any other components which control tank pressure.
3. Excessive vibration can weaken the air tank and cause
rupture or explosion.
Attachments & Accessories: Exceeding the operating pressure
of air tools can cause them to explode.
HOW TO PREVENT IT
The tank is designed to withstand specific operating pressures.
Never make adjustments or parts substitutions to alter the
factory set operating pressures.
For essential control of air pressure, you must install a
pressure regulator and pressure gauge to the air supply
system.
RISK OF BURNS
WHAT CAN HAPPEN
Touching exposed metal such as the compressor head or
outlet tubes, can result in serious burns.
HOW TO PREVENT IT
Never touch any exposed metal parts on compressor during or
immediately after operation. The compressor will remain hot
several minutes after use. Do not reach around protective
shrouds or attempt maintenance until the compressor has
cooled down completely.
1) Read and understand instruction manual before attempting to install
and use compressor. Be thoroughly familiar with the
operational controls and proper use.
2)All electrical and safety codes must be followed to ensure operator
safety.

WITHAMINIMUM 15-AMP. BRANCH CIRCUIT. FAI URE TO CONNECT
IN THIS WAY CAN RESU T IN INJURY FROM SHOCK OR FIRE.
GROUNDING
Your compressor must be properly grounded. Not all outlets are properly
grounded. If you are not sure if your outlet is properly grounded, have it
checked by a qualified electrician.
WARNING: IF NOT PROPER Y GROUNDED, THIS COMPRESSOR
CAN CAUSE E ECTRICA SHOCK, PARTICU AR Y WHEN USED IN
DAMP OCATIONS. TO AVOID SHOCK OR FIRE, IF THE POWER CORD
IS WORN OR DAMAGED IN ANY WAY, HAVE IT REP ACED
IMMEDIATE Y.
If this compressor should malfunction or breakdown, grounding provides a
path of least resistance for electric current, to reduce the risk of electric
shock. This cut-off is equipped with a cord having an equipment-grounding
conductor and grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
WARNING: TO MAINTAIN PROPER GROUNDING, DO NOT REMOVE OR
A TER THE GROUNDING PRONG IN ANY MANNER.
120V OPERATION
As received from the factory, your compressor is ready to run for 120V
operation. This machine is intended for use on a electrical circuit that has
an outlet and a plug which looks like the one illustrated in Fig.1.
WARNING: DO NOT USE A TWO-PRONG ADAPTOR FOR THEY ARE
NOT IN ACCORDANCE WITH OCA CODES AND ORDINANCES.
NEVER USE IN CANADA.

EXTENSION CORDS
The use of any extension cord will cause some loss of power. IT
IS RECOMMENDED TO USE A ONGER AIR HOSE INSTEAD
OF AN EXTENSION CORD. If you do not have a choice, use the
chart in Fig.2 to determine the minimum wire size
(A.W.G-American Wire Gauge) extension cord needed. Use only
3-wire extension cords which have 3-prong grounding type plugs
and 3-hole receptacles which accept the tool’s plug.
For circuits that are further away from the electrical circuit box, the
wire size must be increased proportionately in order to deliver
ample voltage to the compressor motor. Refer to Fig.2 for wire
length and size.

ASSE BLY OFTHEAIRCO PRESSOR
Your compressor requires minor assembly.
1. Install both air filters (A)Fig.3 to the pump castings as shown.
2. Pivot the compressor down towards the front and lay the compressor down on
the front rubber stoppers. Install wheel (A) Fig.4 to the rear wheel bracket. Insert
large bolt through wheel, slide washer onto bolt, then insert bolt into the wheel
bracket as shown, secure wheel using another washer and hex. nut (B). Repeat
for second wheel.
3. Then install both rubber feet (A) Fig.5 to the brackets (B) under the tank using a
washer and hex. nut (C). Reposition the compressor in the upright position.
LOCATION OFTHEAIRCO PRESSOR
Operate the air compressor in a dry, clean, cool, well ventilated area. The air
compressor pump and case are designed to allow for proper cooling. Clean or blow
off dust or dirt that collects on the air compressor. A clean air compressor runs
cooler and provides longer service. The ventilation openings on your air compressor
are necessary to maintain proper operating temperature. Do not place rags or other
containers on or near these openings.
ADDITIONALREGULATORSANDCONTROLS
Since the air tank pressure is usually greater than that which is needed, an air
pressure regulator is employed to control the air pressure ahead of any individual
driven device. Seperate air transformers which combine the function of air
regulation, moisture and dirt removal should be used where applicable.
OPERATIONCONTROLS
CHECKVALVE (A) FIG.6.
When the air compressor is operating, the check valve is “open”, allowing
compressed air to enter the air tank. When the air compressor reaches its “Cut-Out”
pressure, the check valve “closes”, allowing air pressure to remain inside the air
tank.
ELECTRO AGNETIS UNLOADER VALVE (B) FIG.6.
Electronically controls the unloader valve, to effectively start the compressor even
when the tank is full.

TANK PRESSURE GAUGE (A) FIG.7. The tank pressure gauge indicates the
reserve air pressure in the tank.
REGULATOR (B) FIG.7. The air pressure coming from the air tank is controlled by
the regulator. Turn the regulator knob clockwise to increase pressure or
counterclockwise to decrease pressure.
DUAL “ONE TOUCH” 1/4” QUICK RELEASE COUPLERS (C) FIG.7. Connect an
air hose with a 1/4” male coupler installed and connect it to one of the two female
quick release couplers.
OUTLET PRESSURE GAUGE (D) FIG.7. The outlet pressure gauge indicates the
air pressure available at the outlet side of the regulator. The pressure is controlled
by the regulator and is always less than or equal to the tank pressure.
AS E SAFETY VALVE (E) FIG.7. If the pressure switch does not shut off the air
compressor at its cutout pressure setting, the safety valve will protect against high
pressure by “popping out” at its factory set pressure (slightly higher than the pressure
switch cut-out setting).
WARNING!: If the safety valve does not work properly, over pressurization may
occur, causing air tank rupture or an explosion. Daily pull the ring on the safety valve
to make sure that the safety valve operates freely. If the valve is stuck or does not
operate smoothly, it must be replaced with the same ASME type of valve.
ON/AUTO-OFF SWITCH (A) FIG.8. Turn this switch ONto provide power to the
automatic pressure switch and OFF to remove power at the end of each use.
PRESSURESWITCH (B) FIG.8. The pressure switch automatically starts the motor
when the tank pressure drops below the factory set “Cut-In” pressure. It also stops
the motor when the air tank pressure reaches the factory set “Cut-Out” pressure.
DRAIN VALVE (A) FIG.9. The drain valve is located at the base of the air tank and
is used to drain condensation at the end of each use. Turn drain valve counterclock-
wise to open (no pressure build-up) or clockwise to close it (permits pressure build-
up).
Preparation for use:
1. Before attaching an air hose or accessories, make sure the On/Off switch (A) Fig.8
is set to “OFF” and the air regulator (B) Fig.7 is closed (completely turned
counterclockwise).
WARNING: 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 of the tool being
used.
2. Turn the switch (A) Fig.8 to the On position and allow tank pressure to build. Motor
will stop when tank pressure reaches “cut-out” pressure.
3. Open the regulator (B) Fig.7 by turning it clockwise. Adjust the regulator to the
correct pressure setting. The compressor is ready for use.

FIGURE 9

After Use:
1. Set the switch (A) Fig.8 to the Off position. Disconnect power cord from power source.
2. Turn the regulator (B) Fig.7 counterclockwise to set the outlet pressure to zero.
3. Disconnect the air tool or accessory.
4. Pull ring on safety valve (E) Fig.7, allowing air to bleed from the tank until tank pressure is approximately 20 PSI. Release safety valve ring.
5. Drain water from air tank. Turn drain valve (A) Fig.9, counterclockwise to open.
WARNING!: WATER WILL CONDENSE IN THE AIR TANK.
oisture in compressed air
When humidity is high or when the compressor is in continuous use for an extended period of time, this moisture will collect in the air tank. When
using a spray gun or sandblast gun, this water will be carried from the tank through the hose and out of the gun as droplets mixed with the spray
material. This will cause water spots in a paint job, especially when spraying other than water based paint. If sandblasting, it will cause the
material to cake and clog the gun, rendering it ineffective. DRAIN WATER FRO AIR TANK ON A REGULAR BASIS or an optional air control
unit with dirt and moisture removal should be used to prevent these undesireable results.
NOTE: If drain valve is plugged, pull ring on safety valve (E) Fig.7, and hold until all air pressure has been released. The drain valve can then be
removed, cleaned, and reinstalled.
6. After the water has been completely drained, turn drain valve clockwise to close. The air compressor can now be stored.
KEEP TOOL CLEAN
Periodically blow out all air passages with dry compressed air. Clean all plastic parts with a soft damp cloth. NEVERuse solvents to clean
plastic parts. They could possibly dissolve or otherwise damage the material.
CAUTION: Wear safety glasses while using compressed air.
