CFM: Cubic feet per minute.
SOFM: 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.
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
_ 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. 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.
_ MultFViscosity 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: Oil is included with some units. If oil is not included, 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.
1. Place unit on a level surface.
Risk from Flying Object. Drain tank to release air pressure
before removing the dipstick. See "To Drain Tank" in the
"Maintenance" section.
2. Remove oil fill plug (A) and slowly add
a compressor oil until it is even with the
top of the oil fill hole. NOTE: Do not
allow oil to be lower than 3/8" (6 threads)
from the top at any time. When filling
the crankcase, the oil flows very slowly
into the pump. If the oil is added too
quickly, it will overflow and appear to
be full. NOTE: Crankcase oil capacity is
approximately 16 fluid ounces.
3. Replace oil fill plug.

A10260 12- ENG

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 decreas-
es. 10 AWG and 8 AWG may also be used. DO NOT USE14OR16
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 cir-
cuit if the following conditions are met.
1. Voltage supply to circuit must comply with the National Electrical Code.
2. Circuit is not used to supply any other electrical needs.
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.
120/240 Dual Voltage Motor
This model has a dual voltage motor, 120 and 240 volt. It is wired for 120 volt
but can be converted to 240 volt operation. Instructions for connecting the
motor for operation at 240 volt can be found printed on the label attached to
the side of the motor.
When converting to 240V operation, the attached three=
prong 120V cord assembly must be replaced with a three-
pronged 240V cord assembly (K=0080} that can be purchased through a
Authorized Service Center.

Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
On/Auto/Off Tank Pressure
Switch Gauge
Description of Operation
Become familiar with these controls before operating the unit.
On/Auto/Off Lever: Turn this switch to "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.
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.
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.
A10260 14- ENG

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.
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.
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 after the unit reaches "cut-out" pressure.
Motor 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.
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".

quick connect.
3. Plug the power cord into the correct branch circuit receptacle. (Refer to
"Voltage and Circuit Protection" paragraph in the "Installation" section of
this manual.)
Open the drain valve (counter-clockwise) fully to permit air to escape and
prevent air pressure build up in the air tank during the break-in period.
Move the On/Auto/Off lever to "On/Auto" position. The compressor will start.
Run the compressor for 20 minutes. Make sure the drain valve is open and
there is minimal air pressure build-up in tank.
After 20 minutes, close the drain valve by turning clockwise. The air
receiver will fill to "cut-out" pressure and the motor will stop.
A10260

Before Each Start=Up:
Place On/Auto/Off lever to "Off".1.
2. Pull the regulator knob out and turn counterclockwise to set the outlet
pressure to zero.
3. Attach hose and accessories. NOTE: The hose or accessory will require
a quick connect plug if the air outlet is equipped with a quick connect
socket.
_Risk of Bursting. 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.
How to Start:
1. Turn the On/Auto/Off lever to "On/Auto" and allow tank pressure to build.
