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.
ASME: American Society of Mechanical Engineers; made, tested, inspected, and
registered to meet the standards of ASME.
California Code: Unit may comply with California Code 462 (l) (2)/(M) (2).
Specification/model label is on the side of the tank on units that comply with
California Code.
Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to
use your accessory or air tool. 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 you turn on your air compressor and it 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.”
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.
Porter-Cable air compressors should be operated on not more than a 50% duty
cycle. This means an air compressor that pumps air more than 50% of one hour is
considered misuse, because the air compressor is undersized for the required air
demand. Maximum compressor pumping time per hour is 30 minutes.

DESCRIPTION OF OPERATION
Drain Valve (not shown): The drain valve is located at the base of the air tank and
is used to drain condensation at the end of each use.
Motor Thermal Overload Protector (not shown): The electric motor has an
automatic thermal overload protector. If the motor overheats for any reason, the
thermal overload protector will shut off the motor. The motor must be allowed to
cool before restarting.
ON/AUTO - OFF Switch (A) Fig. 1: Turn this
switch ON to provide automatic power to the
pressure switch and OFF to remove power at
the end of each use.
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".
Air Compressor Pump (not shown): To
compress air, the piston moves up and down
in the cylinder. On the downstroke, air is
drawn in through the air intake valves. The
exhaust valve remains closed. On the
upstroke of the piston, air is compressed.
The intake valves close and compressed air is forced out through the exhaust
valve, into the outlet tube, through the check valve and 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 (not shown): 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 (not shown): 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 Switch (B) Fig. 1: 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 (C) Fig. 1: 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 (D) Fig. 1: 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 (E) Fig. 1: The tank pressure gauge indicates the reserve air
pressure in the tank.
Regulator (F) Fig. 1: The air pressure coming from the air tank is controlled by the
regulator knob. Turn the knob clockwise to increase pressure and counterclockwise
to decrease pressure. To avoid minor readjustment after making a change in
pressure setting, always approach the desired pressure from a lower pressure.
When reducing from a higher to a lower setting, first reduce to some pressure less
than that desired, then bring 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 you are operating the accessory.

1. Submerge handle grip (A) into warm soapy water to make installation easier.
Remove handle grip (A) from soapy water and slide onto handle (B).
2. Position legs of handle (B) inside compressor saddle. Align holes in handle
legs with holes in saddle. Using a 3/8” wrench to secure handle in place, using
the four screws provided (two screws (C), through each side of saddle).
It may be necessary to brace or support one end of the
unit when attaching the wheels and the rubber feet, because the air
compressor will have a tendency to tip.
3. Place shoulder bolt through wheel (D) and position it into the top hole of the
mounting bracket. Thread nut onto shoulder bolt and tighten firmly with a 9/16”
wrench. Repeat to install second wheel.
4. Clean and dry air tank leg (E) opposite wheels. Remove the protective paper

Location of the Air Compressor
Locate the air compressor in a clean, dry, and well-ventilated area. The air filter
must be kept clear of obstructions which could reduce air flow to the air
compressor. The air compressor should be located at least 12" away from the wall
or other obstructions that will interfere with the flow of air. The air compressor head
and shroud are designed to allow for proper cooling. If humidity is high, an air filter
can be installed on the air outlet adapter to remove excessive moisture. Follow the
instructions packaged with the air filter for proper installation.
Lubrication and Oil
This unit needs no lubrication or oiling.
Extension Cords
To avoid voltage drop, power loss, and overheating to the motor, use extra air hose
instead of an extension cord. Low voltage can cause damage to the motor.
If an extension cord must be used:
• use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot
receptacle that will accept the plug on the extension cord.
• make sure the extension cord is in good condition.
• the extension cord should be no longer than 50 feet.
• the minimum wire size is 12 gauge (AWG). (Wire size increases as gauge
number decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14
AWG or 16 AWG.)
Voltage and Circuit Protection
Refer to the specification chart for voltage and circuit protection requirements of
your compressor. Use only a fuse or circuit breaker that is the same rating as the
branch circuit on which the air compressor is operated. If the compressor is
connected to a circuit protected by fuses, use only dual element time delay fuses.
Piping
Plastic or PVC pipe is not designed for use with
compressed air. Regardless of its indicated pressure rating, plastic
pipe can burst from air pressure. Use only metal pipe for air
distribution lines.
If a pipe line is necessary, use pipe that is the same size as the air tank outlet.
Piping that is too small will restrict the flow of air. If piping is over 100 feet long, use
the next larger size. Bury underground lines below the frost line and avoid pockets
where condensation can gather and freeze. Apply pressure before underground
lines are covered to make sure all pipe joints are free of leaks.
A flexible coupling needs to be installed between the outlet valve and the main air
distribution line to allow for vibration.

10-ENG
GROUNDING INSTRUCTIONS
RISK OF ELECTRICAL SHOCK! In the event of a short
circuit, grounding reduces the risk of shock by providing an escape
wire for the electric current. This air compressor must be properly
grounded.
If these grounding instructions are not completely understood, or if in doubt as to
whether the compressor is properly grounded, have the installation checked by a
qualified electrician. The air compressor is equipped with a cord having a
grounding wire with an appropriate grounding plug. The plug must be used with an
outlet that has been installed and grounded in
accordance with all local codes and ordinances. The
outlet must have the same configuration as the plug.
See Fig. 3. DO NOT USE AN ADAPTER.
Inspect the plug and cord before each use. Do not
use if there are signs of damage.
Improper grounding can result
in electrical shock!
Do not modify the plug that has been provided. If it
does not fit the available outlet, the correct outlet
should be installed by a qualified electrician.
If repairing or replacing cord or plug, the grounding
wire must be kept separate from the current-carrying
wires. Never connect the grounding wire to a flat
blade plug terminal. The grounding wire has
insulation with an outer surface that is green - with or
without yellow stripes.
Additional Regulators and Controls
Since the air tank pressure is usually greater than that which is needed, a separate
regulator is usually employed to control the air pressure ahead of any individual air
driven device.

BREAK-IN PROCEDURES
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. (before the
hose is installed), the check valve is replaced, or a complete compressor pump is
replaced.
The procedure:
1. Make sure the pressure switch lever is in the "OFF" position.
2. Plug the power cord into the correct branch circuit receptacle.
3. Open the drain valve fully to permit air to escape and prevent air pressure build
up in the air tank during the break-in period.
4. Move the pressure switch lever to "ON/AUTO". The compressor will start.
5. Run the compressor for 15 minutes. Make sure the drain valve is open and
there is minimal air pressure build-up in tank.
6. After 15 minutes, close the drain valve.
7. Move the pressure switch lever to "ON/AUTO".The air receiver will fill to cut-out
pressure and the motor will stop.
The compressor is now ready for use.
OPERATING PROCEDURES
Daily Start-Up Checklist
1. Before attaching air hose or accessories, make sure the ON/AUTO lever is set to
“OFF” and the air regulator is closed.

2. Remove shroud.
3. Loosen the top and bottom nuts and remove the outlet tube.
4. Remove the pressure release tube and fitting.
MAINTENANCE
Unit cycles automatically when power is on. During
maintenance, you could be exposed to voltage sources, compressed
air, moving parts, or hot surfaces. Personal injuries can occur. Unplug
the unit and bleed off all air tank pressure and allow unit to cool
before doing any maintenance or repair. Never operate the unit with
the belt guard removed.
To ensure efficient operation and longer life of the air compressor unit, a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to an unit in a normal working environment
operating on a daily basis. If necessary, the schedule should be modified to suit the
conditions under which your compressor is used. The modifications will depend
upon the hours of operation and the working environment. Compressor units in an
extremely dirty and/or hostile environment will require a greater frequency of all
maintenance checks.
ROUTINE MAINTENANCE SCHEDULE
Daily:
1. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is
approximately 20 psi. Release safety valve ring.
2. Drain water from the air tank, any moisture separators, or transformers.
3. Check for any unusual noise and/or vibration.
4. Manually check safety valve to make sure of proper operation.
5. Inspect air filter and replace if necessary.
6. Inspect air lines and fittings for leaks; correct as necessary.

5. Unscrew the check valve using a socket wrench.
6. Check that the valve disc moves freely inside the check valve and that the
spring holds the disc in the upper, closed position. The check valve may be
cleaned with a strong solvent.
7. Apply sealant to the check valve threads. Reinstall the check valve.
8. Replace the pressure release tube and fitting.
9. Replace the outlet tube and tighten top and bottom nuts.
10.Replace the shroud.
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/or is running.

then remove and clean or replace
check valve. DO NOT OVER-
TIGHTEN.
Air leaks in air tank or
at air tank welds.
Damaged air tank. DO NOT
DRILL INTO, WELD OR
OTHERWISE MODIFY AIR
TANK OR IT WILL
WEAKEN. THE TANK CAN
RUPTURE OR EXPLODE.
TANK MUST BE RE-
PLACED.
Air leaks between
head and valve
plate.
Leaking o-ring. Torque head screws to 8 ft. lbs. If
this does not stop leak, replace o-
ring.
Pressure reading on
the regulated
pressure gauge
drops when an
accessory is used.
It is normal for “some”
pressure drop to occur.
If there is an excessive amount of
pressure drop when the accessory
is used, adjust the regulator
following the instructions on page
7. NOTE: Adjust the regulated
pressure under flow conditions
(while accessory is being used).

CAUSEPROBLEM CORRECTION
Motor will not run or
restart.
Motor overload protection
switch has tripped.
Tank pressure exceeds
pressure switch “cut-in”
pressure.
Wrong gauge wire or length of
extension cord.
Check valve stuck open.
Loose electrical connections.
Possible malfunctioning motor
or starting capacitor.
Paint spray on internal motor
parts.
Fuse blown, circuit breaker
tripped.
Pressure release valve on
pressure switch has not
unloaded head pressure.
Let motor cool off and overload
switch will automatically reset.
Motor will start automatically when
tank pressure drops below “cut-in”
pressure of pressure switch.
Check for proper gauge wire and
cord length.
Remove and clean, or replace.
Check wiring connection inside
pressure switch and terminal box
area.
Contact an Authorized Warranty
Service Center for inspection or
replacement, if necessary.
Have checked by an Authorized
Warranty Service Center. Do not
operate the compressor in the paint
spray area. See flammable vapor
warning.
1. Check fuse box for blown fuse
and replace, if necessary. Reset
circuit breaker. Do not use a
fuse or circuit breaker with
higher rating than that specified
for your particular branch circuit.
2. Check for proper fuse; only time
delay fuses are acceptable.
3. Check for low voltage
conditions and/or proper
extension cord.
4. Disconnect the other electrical
appliances from circuit or
operate the compressor on its
own branch circuit.
Bleed the line by pushing the lever
on the pressure switch to the “off”
position; if the valve does not open,
replace it.

Operate safety valve manually by
pulling on ring. If valve still leaks, it
should be replaced.
Possible defect in safety valve.Air leak from safety
valve.
CAUSEPROBLEM CORRECTION
Knocking Noise. Malfunctioning check valve. Remove and clean, or replace.
Compressor is not
supplying enough air
to operate
accessories.
Prolonged excessive use of air.
Compressor is not large
enough for air requirement.
Restricted air intake filter.
Hole in hose.
Check valve restricted.
Air leaks.
Decrease amount of air usage.
Check the accessory air
requirement. If it is higher than the
SCFM or pressure supplied by your
air compressor, you need a larger
compressor.
Clean or replace air intake filter. Do
not operate the air compressor with
the filter removed. See page 12.
Check and replace if required.
Remove and clean, or replace.
Tighten fittings. (See Air Leaks
Section of Troubleshooting Guide.)
