GLOSSARY  
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.  
Become familiar with these terms  
before operating the unit.  
CFM: Cubic feet per minute.  
SCFM: Standard cubic feet per  
minute; a unit of measure of air  
delivery.  
PSIG: Pounds per square inch  
gauge; a unit of measure of pressure.  
Code Certification: Products that  
bear one or more of the following  
marks: UL, CUL, ETL, CETL, have  
been evaluated by OSHA certified  
independent safety laboratories and  
meet the applicable Underwriters  
Laboratories Standards for Safety.  
Cut-In Pressure: While the motor  
is Off, air tank pressure drops as  
you continue to use your accessory.  
Branch Circuit: 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.  
ACCESSORIES  
Accessories for this unit are available at the store the unit was purchased.

Extension Cords  
Voltage and Circuit Protection  
Using extension cords is not  
recommended. The use of extension  
cords will cause voltage to drop  
resulting in power loss to the motor  
and overheating.  
Instead of using an extension cord,  
increase the working reach of the  
air hose by attaching another length  
of hose to its end. Attach additional  
lengths of hose as needed.  
Refer to the specification chart for the  
voltage and minimum branch circuit  
requirements.  
Certain air  
compressors can  
be operated on a 15 amp circuit if  
the following conditions are met.  
1. Voltage supply to circuit must  
comply with the National  
Electrical Code.  
If an extension cord must be used, be  
sure it is:  
2. Circuit is not used to supply any  
other electrical needs.  
a 3-wire extension cord that has  
a 3-blade grounding plug, and a  
3-slot receptacle that will accept  
the plug on the product  
3. Extension cords comply with  
specifications.  
4. Circuit is equipped with a 15 amp  
circuit breaker or 15 amp time  
delay fuse. NOTE: If compressor  
is connected to a circuit  
in good condition  
no longer than 50 feet  
12 gauge (AWG) or larger. (Wire  
size increases as gauge number  
decreases. 10 AWG and 8 AWG  
may also be used. DO NOT USE  
14 OR 16 AWG.)  
protected by fuses, use only time  
delay fuses. Time delay fuses  
should be marked "D" in Canada  
and "T" in the US.  
If any of the above conditions  
cannot be met, or if operation of  
the compressor repeatedly causes  
interruption of the power, it may be  
necessary to operate it from a 20 amp  
circuit. It is not necessary to change  
the cord set.

and counterclockwise to decrease  
pressure.  
Quick Connect Body: The quick  
connect body accepts Industrial quick  
connect plugs to make connections  
simple and easy.  
Cooling System (not shown): This  
compressor contains an advanced  
design cooling system. At the heart of  
this cooling system is an engineered  
fan. It is perfectly normal for this fan  
to blow air through the vent holes  
in large amounts. You know that the  
cooling system is working when air is  
being expelled.  
Air Compressor Pump (not shown):  
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.  
Description of Operation  
Become familiar with these controls  
before operating the unit.  
On/Auto/Off Switch: Turn this switch  
"On/Auto" to provide automatic power  
to the pressure switch and "Off" to  
remove power at the end of each use.  
Pressure Switch: The pressure  
switch 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 will protect against high  
pressure by "popping out" at its factory  
set pressure (slightly higher than the  
pressure switch "cut-out" setting).  
Tank Pressure Gauge: The tank  
pressure gauge indicates the reserve  
air pressure in the tank.  
Outlet Pressure Gauge: The outlet  
pressure gauge indicates the air  
pressure available at the outlet side of  
the regulator. This pressure is controlled  
by the regulator and is always less than  
or equal to the tank pressure.  
A09770

Air Intake Filter (not shown): This  
filter is designed to clean air coming  
into the pump. This filter must always  
be clean and ventilation openings free  
from obstructions. See "Maintenance".  
Drain Valve: The  
drain valve is located  
at the base of the air  
tank and is used to  
drain condensation at  
the end of each use.

STORAGE  
Risk of Bursting.  
Water will condense  
in the air tank. If not drained, water  
will corrode and weaken the air tank  
causing a risk of air tank rupture.  
Before you store the air compressor,  
make sure you do the following:  
1. Review the "Maintenance"  
section on the preceding  
pages and perform scheduled  
maintenance as necessary.  
7. After the water has been drained,  
close the drain or drain valve.  
2. Set the On/Auto/Off lever to "Off"  
and unplug unit.  
NOTE: If drain valve is plugged,  
release all air pressure. The valve  
can then be removed, cleaned, then  
reinstalled.  
3. Turn the regulator  
counterclockwise and set the  
outlet pressure to zero.  
8. Protect the electrical cord and  
air hose from damage (such as  
being stepped on or run over).  
Wind them loosely around the  
compressor handle.  
4. Remove the air tool or accessory.  
5. Pull ring on safety valve allowing  
air to bleed from the tank until  
tank pressure is approximately 20  
psi. Release safety valve ring.  
9. Store the air compressor in a  
clean and dry location.  
6. Drain water from air tank by  
opening drain valve on bottom of  
tank.
