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 indepenent 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.

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.

Fig. 2
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.

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.

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

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

5. Inspect air filter and replace if necessary.
6. Inspect air lines and fittings for leaks and 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 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
