I__ Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals
known (to the State of California) to cause cancer, birth defects or other
reproductive harm. Some example of these chemicals are:
• lead from lead-based paints
•crystalline silica from bricks and cement and other masonry products
• arsenic and chromium from chemically-treated lumber
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, always wear
MSHA/NIOSH approved, properly fitting face mask or respirator when using
such tools.
When using air tools, basic safety precautions should always be followed to
reduce the risk of of personal injury.

WARNING: Risk of explosion or fire
What Could Happen
If electrical sparks from compressor
come into contact with flammable
vapors, they may Ignite, causing fire or
explosion,
Unattended operation of this product
could result in personal injury or
property damage. To reduce the risk of
fire, do not allow the compressor to
operate unattended.
How To Prevent It
If spraying flammable materials, locate
compressor at least 20 feet away from
spray area. An additional length of hose
may be required.
Store flammable materials in a secure
location away from compressor.
Always remain in attendance with the
perating.

WARNING: Risk of Bursting
Air Tank: The following conditions could lead to a weakening of the tank, and result
in a violent tank explosion and could cause property damage or serious injury.
What Could Happen
Faiiure t0 pr0_eriy drain condensed
water from tank; causing rust and
thinnlng of the steel tank.
Modifications or attempted repairs to
the tank.
Unauthorized modifications to the
unloader valve, safety valve, or any
other components which control tank
pressure.
Excessive vibration can weaken the
rupture Or
explosio n
ATTACHMENTS &ACCESSORIES:
Exceeding the pressure rating of air
tools, spray guns, sir operated
accessories, tires, and other inflatables
can cause them to explode or fly apart,
and could result in serious injury.
How To Prevent It
Drain tank daily or after each use. If
tank develops a leak, replace it
immediately with anew tank or reptace
the entire Compressor.
Never drill into, weld, or make any
modifications to the tank or its
attachments.
The tank is designed to withstand specific
operating pressures. Never make
adjustments Or parts substitutions to
alter the factory set operating
pressureS.
For essential control of air pressure, you
must install a pressure regulator and
pressure gauge to the air outlet (if not
equipped) of your compressor. Follow the
equipment manufacturers
recommendation and never exceed the
maximum allowable pressure rating of
attachments. Never use compressor to
inflate small low pressure objects such
as children's toys, footballs,
basketballs, etc.

WARNING: Risk of Unsafe Operation
What Could Happen
Unsafe operation of your air compressor
could lead to serious injury or death to
you or others.
How To Prevent It
Review and understand all instructions
and warnings in this manual
Become familiar with the operation and
controls of the air compressor.
Keep operating area clear of all persons,
pets, and obstacles.
Keep children away from the air
compressor at all times.
Do not operate the product when
fatigued or under the influence of
alcohol or drugs. Stay alert at all times.
Never defeat the safety features ofthis
product.
Equip area of operation with a fire
extinguisher.
Do not operate machine with missing,
broken, or unauthorized parts.

Become familiar with these terms before operating the unit.
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.

Unpacking
1, Remove unit from carton and discard all packaging.
HOW TO SET UP YOUR UNIT
Location of the Air Compressor
Locate the air compressor in a clean, dry and well ventilated area. 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 pump
and shroud are designed to allow for proper cooling. The ventilation openings
on the compressor are necessary to maintain proper operating temperature. Do
not place rags or other containers on or near these openings.
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.
The portable air compressor is equipped with a cord having a grounding wire
with an appropriate grounding plug (see following illustrations), The plug must
be used with an outlet that has been installed and grounded in accordance
with all local codes and ordinances.
1. The cord set and plug with this unit contains a grounding pin. This plug
MUST be used with a grounded outlet.
IMPORTANT: The outlet being used must be installed and grounded in
accordance with all local codes and ordinances.
2. Make sure the outlet being used has
3,
4.
the same configuration as the
grounded plug. DO NOT USE AN
ADAPTER. See illustration.
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 ifoperation of the compressor
repeatedly causes interruption of the power, it may be necessary to operate it
from a20 amp circuit. It is not necessary to change the cord set.
