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.

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.

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.

4.

Inspect the plug and cord before each

use. Do not use if there are signs of

damage.

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.

IMPROPER GROUNDING CAN RESULT IN ELECTRICAL

SHOCK.

Do not modify the plug provided. If it does not fit the available outlet, a

correct outlet should be installed by a qualified electrician,

Repairs to the cord set or plug MUST be made by a qualified electrician.

9-ENG D28379

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 decreases.

10 AW(3 and 8 AWG may also be used. DO NOT USE 14 OR

16 AWG.)

Voltage and Circuit Protection

Refer to the Parts Manual for the voltage and minimum branch circuit

requirements.

Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.

1.

Voltage supply through branch circuit is 15 amps.

2.

Circuit is not used to supply any other electrical needs (lights, appliances, etc.).

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.

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.

Description of Operation

Become familiar with these controls before operating the unit,

On/Auto/Off

Switch (A): Turn this

switch ON to provide automatic power

to the pressure switch and OFF to

remove power at the end of each use,

Pressure Switch (B): 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): 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):

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): The tank pressure gauge indicates the reserve air

pressure in the tank.

Regulator (F): 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.

Universal Quick-Connect

Body (G): The universal quick-connect body accepts the three most popular styles of quick-connect plugs- Industrial,

automotive (Tru-flate), and ARO. One hand push-to-connect operation makes

connections simple and easy. The two quick connect bodies allow the use of

two tools at the same time.

Remote Console (H): Permits remote air regulation and control closer to work area, includes two high-flow industrial/automotive style compatible quick-

connects, outlet pressure gauge, and a high-flow regulator.

11-ENG D28379

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 unti{ the compressor has raised the air tank pressure above that required at the air outlet.

Drain Valve(I),, The drain valve is located at the base of the air tank and is used to drain condensation at the end of each

use.

Cheek Valve (L)." 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.

Air Intake Filter (K): 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".

Pressure Release Valve (M): 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.
