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.
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 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. 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.

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.)
8-ENG
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 air discharge valve outlet and main air distribution line to allow for vibration.
GROUNDING INSTRUCTIONS
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.
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 air­driven device.
