COMPLETELY AND CAREFULLY
BEFORE OPERATING THIS OILFREE AIR COMPRESSOR KIT.
POWER SUPPLY
Your compressor must be
connected to a 120V outlet,
using a 15-amp time delay fuse
or circuit breaker. 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 have
hesitations on whether or not
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. If the
power cord is worn or
damaged in any way have it
replaced immediately.
If the compressor should
breakdown, the grounding
provides a path of least
resistance for the electric
current which reduces the risk
of electric shock. The plug
must be plugged into an
appropriate outlet that is
grounded in accordance with
the local codes and
ordinances.

proper grounding, do not
alter the grounding prong in
any manner.
CHECK VALVE
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.
120V OPERATION
As received from the factory,
your compressor is ready to run
for 120V operation. This
machine is intended for use on
a circuit that has an outlet and a
plug which looks like the one
illustrated in Fig.1.
WARNING: Do not use a twoprong adapter.
When the compressor is
operating, the check valve 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.
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.
OUTLET PRESSURE GUAGE

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 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.
PRESSURE SWITCH
The pressure switch
automatically starts the motor
when the tank pressure drips
below the factory set “Cut-in”
pressure. It also stops the motor
when the air tank pressure
reaches the factory set “Cut-Out”
pressure.
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.

ADDITIONAL REGULATORS
AND CONTROLS
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).
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.
Separate air transformers which
combine the function of air
regulation, moisture and dirt
removal should be used where
applicable.
WARNING: If the safety
pressure release valve does
not work properly, over
pressurization may occur,
causing air tank to rupture or
explode. Pull the ring on the
safety valve daily 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 type of valve.
SETTING UP YOUR AIR
COMPRESSOR
Operate the air compressor in a
dry, clean and well ventilated
area. Clean 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 near these
openings.

PREPARATION FOR USE
1) Check the oil level. Add the
appropriate amount of oil to the
compressor.
2) Before attaching the air hose or
accessories, make sure the
On/Off switch is set to “OFF” and
the air regulator is closed
(completely turned
counterclockwise).
3) Attach the 1/4in. female fitting
(A Fig.7) to one end of the coil
hose (B), then connect the female
fitting (A) into the quick connect
outlet (C) at the back of the
compressor, then attach the 1/4in.
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.
4) Turn the switch to the On
position and allow tank
pressure to build. Motor will
stop when tank pressure
reaches “cut-out” pressure.
5) Open the regulator by
turning it clockwise. Adjust the
regulator to the correct
pressure setting. The
compressor is ready.
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.
AFTER USE
1) Set the switch to Off.
2) Turn the regulator
counterclockwise to set the
outlet pressure to zero.
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.
WARNING: Water will
condense in the air tank. The
water will corrode and
weaken the air tank causing
a risk of air tank rupture if it
is not drained properly.
NOTE: If drain valve is
3
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 the drain
valve 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.
This could possibly dissolve or
otherwise damage the material.
CAUTION: Wear safety glasses
while using compressed air.
MAINTENANCE
FAILURE TO START
Before doing any maintenance or
adjustments to your air
compressor, the following safety
precautions should be taken:
Should your compressor fail to
start, check to make sure the
prongs on the cord plug are
making good contact with the
outlet. Also, check compressor
fuse or tripped circuit breakers in
the line.
- Disconnect electrical power.
- Release air tank pressure.
DAILY OR BEFORE EACH USE
1) Drain condensation from tank.
2) Check for unusual noise or
vibration.
3) Be sure all nuts and bolts are
tight.
4) Check the oil level.
5) Check the air filter.
After 500 hours of operation,
change the oil.
