GLOSSARY  
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. 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: 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.

To Add Oil To Pump  
DO NOT ATTEMPT TO OPERATE THIS AIR COMPRESSOR  
WITHOUT FIRST ADDING OIL TO THE CRANKCASE.  
Serious damage can result from even limited operation unless filled with  
oil and broken in correctly. Make sure to closely follow initial start-up  
procedures.  
COMPRESSORS ARE SHIPPED WITHOUT OIL. A small  
amount of oil may be present in the pump upon receipt of  
the air compressor. This is due to plant testing and does not mean the  
pump contains oil.  
Multi-Viscosity motor oils, like 10W 30, should not be used  
in an air compressor. They leave carbon deposits on  
critical components, thus reducing performance and compressor life. Use  
air compressor oil only.  
NOTE: Use an oil specifically formulated for use in an air compressor, such as  
Porter-Cable PAS1 air compressor oil. Oil may be found at the store where the  
air compressor was purchased.

Extension Cords  
Use extra air hose instead of an extension cord to avoid voltage drop and  
power loss to the motor, and to prevent overheating.  
If an extension cord must be used, be sure it is:  
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  
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.)  
Voltage and Circuit Protection  
Refer to the Parts Manual 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 through branch circuit is 15 amps.  
2. Circuit is not used to supply any other electrical needs (lights, appliances,  
etc.).  
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 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.

Pressure  
Gauge  
Pressure  
Switch  
ON 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.  
Regulator  
On/Auto/Off  
Switch  
Safety Valve  
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).  
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.  
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air  
pressure in the tank.  
Regulator: Controls the air pressure shown on the outlet 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.  
Universal Quick-Connect Body: The universal quick-connect body accepts  
the three most popular styles of quick-connect plugs- Industrial, automotive  
(Tru-flate), and ARO. One hand push-to-connect operation makes connections  
simple and easy.  
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.  
Cooling System (not shown): This compressor  
contains an advanced design cooling system. At  
the heart of this cooling system is an engineered  
Drain  
Valve  
fan. It is perfectly normal for this fan to blow air over the pump head, cylinder  
sleeve, and crankcase. You know 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.  
13- ENG  
A02233  
 
Dipstick: Indicates the amount of oil in the pump, the +  
mark indicates full and the - mark indicates oil needs to  
be added. See Oil paragraphs in the Maintenance section  
for instructions.  
Motor Thermal Overload Protector (not shown): The  
motor has an automatic reset thermal overload protector.  
If the motor overheats for any reason, the overload  
protector will shut off the motor. The motor must be  
allowed to cool down before restarting. The compressor  
will automatically restart after the motor cools.  
Dipstick  
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".  
Check Valve: When the air compressor is  
operating, the check valve is “open”, allowing  
compressed air to enter the air tank. When the  
Pressure  
Release  
Valve  
air compressor reaches “cut-out” pressure, the  
check valve “closes”, allowing air pressure to  
remain inside the air tank.  
Check  
Valve  
Pressure Release Valve: The pressure release  
valve located on the side of the pressure switch,  
is designed to automatically release  
compressed air from the compressor head and  
the outlet tube when the air compressor  
reaches “cut-out” pressure or is shut off. The  
pressure release valve allows the motor to restart freely. When the motor stops  
running, air will be heard escaping from this valve for a few seconds. No air  
should be heard leaking when the motor is running, or continuous leaking after  
unit reaches “cut-out” pressure.  
How to Use Your Unit  
How to Stop:  
1. Set the On/Auto/Off lever to “OFF”.  
Before Starting  
Break-in Procedure  
Serious damage may result if the following break-in  
instructions are not closely followed.  
This procedure is required before the air compressor is put into service and  
when the check valve or a complete compressor pump has been replaced.

exposed when filter cover is removed. Allow compressor  
to cool prior to servicing.  
A dirty air filter will not allow the compressor to operate at full capacity. Keep  
the air filter clean at all times.  
1. Remove the air filter cover.  
2. Remove the air filter from filter cover.  
IMPORTANT: Do not operate the compressor with the air filter removed.  
3. Place new air filter into filter cover. Refer to the “Repair Parts” for the  
correct part number.  
4. Replace air filter cover and lock into place.  
Motor  
The motor has an automatic reset thermal overload protector. If the motor  
overheats for any reason, the overload protector will shut off the motor. The  
motor must be allowed to cool down before restarting. The compressor will  
automatically restart after the motor cools.  
If the overload protector shuts the motor off frequently, check for a possible  
voltage problem. Low voltage can also be suspected when:  
1. The motor does not get up to full power or speed.  
2. Fuses blow out when starting the motor; lights dim and remain dim when  
motor is started and is running.

SERVICE AND ADJUSTMENTS  
Unit cycles automatically when power is on. When doing  
Maintenance, you may be exposed to voltage sources,  
compressed air or moving parts. Personal injuries can occur. Before  
performing any Maintenance or repair, unplug the compressor and bleed  
off all air pressure.  
ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE  
PERFORMED BY TRAINED SERVICE TECHNICIAN.  
Before servicing:  
Unplug or disconnect electrical supply to the air compressor.  
Bleed tank of pressure.  
Allow the air compressor to cool.  
To Replace Regulator  
1. Release all air pressure from air tank. See “To Drain Tank” in the  
Maintenance section.  
2. Unplug outfit.  
3. Using an adjustable wrench remove the gauges and quick connect from  
the regulator.  
4. Remove the regulator.  
5. Apply pipe sealant tape to the nipple on the pressure switch.  
6. Assemble the regulator and orient as shown.  
NOTE: Arrow indicates flow of air. Make sure it is pointing  
Regulator

STORAGE  
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.  
2. Set the On/Auto/Off lever to “OFF”.  
3. Turn the regulator counterclockwise and set the outlet pressure to zero.  
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.  
6. Drain water from air tank by opening drain valve on bottom of tank.  
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.  
7. After the water has been drained, close the drain or drain valve.  
NOTE: If drain valve is plugged, release all air pressure. The valve can then be  
removed, cleaned, then reinstalled.  
8. Loosen knobs on handle and fold handle down for storage. Retighten  
knobs.  
RECOMMENDED HANDLE  
STORAGE  
ALTERNATE HANDLE STORAGE  
9. Protect the electrical cord and air hose from damage (such as being  
stepped on or run over). Wind them loosely around the compressor  
handle.  
10. Store the air compressor in a clean and dry location.
