GLOSSARY  
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.  
DUTY CYCLE  
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.  
B
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.  
A
D
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".  
E
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.  
F
C
Fig. 1  
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.

INSTALLATION  
Installing Handles, Wheel, and Rubber Foot (Fig. 2)  
THE WHEELS AND HANDLE DO NOT PROVIDE  
ADEQUATE CLEARANCE, STABILITY OR SUPPORT FOR PULLING  
THE UNIT UP AND DOWN STAIRS OR STEPS. THE UNIT MUST BE  
LIFTED, OR PUSHED UP A RAMP.  
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.

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.

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.  
Fig. 3  
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.  
10-ENG  
 
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. Attach hose and accessories.  
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.  
3. Turn the ON/AUTO lever to “AUTO” and allow tank pressure to build. Motor will  
stop when tank pressure reaches “cut-out” pressure.  
4. Open the regulator by turning it clockwise. Adjust the regulator to the correct  
pressure setting. Your compressor is ready for use.  
5. Always operate the air compressor in well-ventilated areas; free of gasoline or  
other combustible vapors. If the compressoris being used to operate a sprayer  
DO NOT use near the spray area..  
When you are finished:  
6. Set the “ON/AUTO” lever to “OFF”.  
7. Turn the regulator counterclockwise and set the outlet pressure to zero.  
8. Remove the air tool or accessory.  
9. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is  
approximately 20 psi. Release safety valve ring.  
10.Drain water from air tank by opening drain cock 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.  
11.After the water has been drained, close the drain cock or drain valve. The air  
compressor can now be stored.  
NOTE  
If drain cock valve is plugged, release all air pressure. The valve can then  
be removed, cleaned, then reinstalled.

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.  
Each Year of Operation or if a Problem is Suspected:  
Check condition of air compressor pump intake and exhaust valves. Replace if  
damaged or worn out.  
SERVICE INSTRUCTIONS  
Air Filter - Inspection and Replacement  
Keep the air filter clean at all times. Do not operate the compressor with the air  
filter removed. A dirty air filter will not allow the compressor to operate at full  
capacity. Before you use the compressor, check the air filter to be sure it is clean. If  
it is dirty, simply pull it out. You may wash it with a mild detergent and warm water,  
or replace it.  
Safety Valve - Inspection  
IF THE SAFETY VALVE DOES NOT WORK PROPERLY,  
OVER-PRESSURIZATION MAY OCCUR, CAUSING AIR TANK  
RUPTURE OR AN EXPLOSION. DAILY PULL THE RING ON THE  
SAFETY VALVE TO MAKE SURE THAT THE SAFETY VALVE OPERATES  
FREELY. IF THE VALVE IS STUCK OR DOES NOT OPERATE  
SMOOTHLY, IT MUST BE REPLACED WITH THE SAME TYPE OF  
VALVE.  
Check Valve Replacement  
1. Release all air pressure from air tank and unplug unit.  
2. Remove shroud.  
3. Loosen the top and bottom nuts and remove the outlet tube.  
4. Remove the pressure release tube and fitting.  
12-ENG  
 
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.
