WARNING

ALL ELECTRICAL CONNECTIONS MUST BE DONE BY A QUALIFIED ELECTRICIAN. FAILURE TO COMPLY MAY RESULT IN
SERIOUS INJURY! ALL ADJUSTMENTS OR REPAIRS MUST BE DONE WITH THE COMPRESSOR DISCONNECTED FROM THE
POWER SOURCE. FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY!

WARNING:

FAILURE TO CONNECT IN THIS WAY CAN RESULT 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 PROPERLY GROUNDED, THIS COMPRESSOR
CAN CAUSE ELECTRICAL SHOCK, PARTICULARLY WHEN USED IN
DAMP LOCATIONS. TO AVOID SHOCK OR FIRE, IF THE POWER CORD
IS WORN OR DAMAGED IN ANY WAY, HAVE IT REPLACED
IMMEDIATELY.

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 compressor 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.

ARNING: TO MAINTAIN PROPER GROUNDING, DO NOT REMOVE OR

EXTENSION CORDS

The use of any extension cord will cause some loss of power. IT
IS RECOMMENDED TO USE A LONGER AIR HOSE INSTEAD
OF AN EXTENSION CORD. Use the chart below to determine
the minimum wire size (A.W.G-American Wire Gauge) extension
cord. 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 motor. Refer to Fig.2 for wire length and
size.

OPERATION CONTROLS

CHECK VALVE

hen the air compressor is operating, the check valve is “open”, allowing compressed

W
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.

ON/OFF SWITCH (A) FIG.3

Turn this switch ON (press downwards) to provide power to the automatic pressure
switch and OFF to remove power at the end of each use.

PRESSURE SWITCH

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.

REGULATOR (A) FIG.4

The air pressure coming from the air tank is controlled by the regulator. Turn the
regulator knob clockwise to increase pressure and counterclockwise to decrease
pressure. To avoid minor readjustment after making a change in the pressure setting,
always approach the desired pressure from a lower pressure. When reducing from a
higher to a lower setting, first reduce the pressure less than that desired, then bring it up
to the desired pressure. Depending on the air requirements of each particular
accessory, the outlet regulated air pressure may have to be adjusted while operating the
accessory.

OUTLET PRESSURE GAUGE (B) FIG.4

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.

TANK PRESSURE GAUGE (C) FIG. 4

The tank pressure gauge indicates the reserve air pressure in the tank.

FIGURE 3

FIGURE 4

DRAIN VALVE (A) FIG. 5

The drain valve is located at the base of the air tank and is used to drain condensation
at the end of each use.

SAFETY PRESSURE RELEASE VALVE (A) FIG.6

If the pressure switch does not shut off the air compressor at its cutout pressure setting
and the air pressure keeps rising, the safety valve will protect against high pressure by
“popping out” above factory set pressure (slightly higher than the pressure switch
cut-out setting).

WARNING!: If the safety pressure release valve does not work properly, over
pressurization may occur, causing air tank rupture or an explosion. Pull the ring on the
safety valve daily to make sure that the safety valve operates freely
or does not operate smoothly

, it must be replaced with the same type of valve.

SET-UP, OPERATION & STORING

ETTING UP YOUR AIR COMPRESSOR

S

Operate the air compressor in a dry, clean, cool, well ventilated area. 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

perating temperature. Do not place rags or other containers on or near these openings.

o

DDITIONAL REGULATORS AND CONTROLS

A

Since the air tank pressure is usually greater than that which is needed, a 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.

Preparation for use:

1. Before attaching air hose or accessories, make sure the On/Off switch is set to “OFF”
and the air regulator is closed (completely turned counterclockwise).

2. Attach the 1/4” female fitting (A) Fig.7 to one end of coil hose (B), then connect the
femal fitting (A) into the quick connect outlet (C) at the back of the compressor, then
attach the 1/4” female quick connect (D) to the other end of the coil hose. Attach
optional air tool or supplied accessories. To prevent air leaks, it is recommended to
install Teflon Tape (not supplied) on the threads at both ends of the coil hose.

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.

3. Turn the switch to the On position and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure.

4. Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. The compressor is ready for use.

After Use:

1. Set the switch to Off.

Turn the regulator counterclockwise to set the outlet pressure to zero.

2.

3. Disconnect the air tool or accessory.

4. Pull ring on safety valve (A) Fig. 6, 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. 5, counterclockwise to open.

ARNING!: WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED WATER WILL CORRODE AND WEAKEN THE AIR TANK

W

CAUSING A RISK OF AIR TANK RUPTURE.

NOTE: If drain valve is plugged, pull ring on safety valve (A) Fig. 6, 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 to close. The air compressor can now be stored.

MAINTENANCE & TROUBLESHOOTING

MAINTENANCE

Before doing any maintenance or adjustments to your air compressor, the following safety precautions should be taken:

- Disconnect electrical power.
Release air tank pressure.

-

aily or before each use:

D

1. Drain condensation from tank.

2. Check for any unusual noise or vibration.

3. Be sure all nuts and bolts are tight.

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.

FAILURE TO START

Should your compressor fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check
compressor fuse or tripped circuit breakers in the line.
