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.

ASSEMBLY
To Add Oil To Pump
Risk of Unsafe Operation. 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.
Risk of Unsafe Operation. 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.
Risk of Unsafe Operation. Multi-Viscosity motor oils, like
10W30, 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.

10- ENG
A10055
Extension Cords
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.
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 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 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.

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- Industial, automotive
(Tru-flate), and ARO. One hand push-to-connect operation makes connections
simple and easy. The two quick connect bodies allow the use of two tools at
the same time.
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
Drain Valve
the heart of this cooling system is an engineered
fan. It is perfectly normal for this fan to blow air over the pump head, clylinder
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.

Check
Valve
Check Valve: When the air compressor is operating,
the check valve is "open", allowing compressed 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.
Air Intake
Filter
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.

pressure is approximately 20 psi. Release safety valve ring.
6. Drain water from air tank by opening drain valve on bottom of tank.
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.
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. Protect the electrical cord and air hose from damage (such as being
stepped on or run over). Wind them loosely around the compressor
handle (If so equipped).
Store the air compressor in a clean and dry location.
