SAVE THESE INSTRUCTIONS
IMPROPER OPERATION OR MAINTENANCE OF THIS PRODUCT COULD RESULT
IN SERIOUS INJURY AND PROPERTY DAMAGE. READ AND UNDERSTAND ALL
WARNINGS AND OPERATING INSTRUCTIONS BEFORE USING THIS EQUIPMENT.
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
It is normal for electrical contacts
within the motor and pressure switch to
spark.
If electrical sparks from compressor
come into contact with flammable
vapors, they may ignite, causing fire or
explosion.
Restricting any of the compressor
ventilation openings will cause serious
overheating and could cause fire.
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
Always operate the compressor in a
well ventilated area free of combustible
materials, gasoline, or solvent vapors.
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.
Never place objects against or on top
of compressor. Operate compressor
in an open area at least 12 inches
away from any wall or obstruction that
would restrict the flow of fresh air to the
ventilation openings.
Operate compressor in a clean, dry well
ventilated area. Do not operate unit
indoors or in any confined area.
Always remain in attendance with the
product when it is operating.
Always disconnect electrical power by
moving pressure switch lever to the off
position and drain tank daily or alter
each use.

in a violent tank explosion and could cause property damage or serious injury.
What Could Happen How To Prevent It
Failure to properly drain condensed Drain tank daily or after each use.

thinning of the steel tank. immediately with a new tank or replace
the entire compressor.
Modifications or attempted repairs to Never drill into, weld, or make any
the tank. modifications to the tank or its
Unauthorized modifications to the attachments.
unloader valve, safety valve, or any
other components which control tank
pressure.
Excessive vibration can weaken the
air tank and cause rupture or
explosion
ATTACHMENTS & ACCESSORIES:
Exceeding the pressure rating of
air tools, spray guns, air operated
accessories, tires, and other inflatables
can cause them to explode or fly apart,
and could result in serious injury.
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 from Flying Objects
What Could Happen How To Prevent It
The compressed air stream can cause
soft tissue damage to exposed skin
and can propel dirt, chips, loose
particles, and small objects at high
speed, resulting in property damage or
personal injury.
Always wear ANSI Z87.1 approved safety
glasses with side shields when using the
compressor.
Never point any nozzle or sprayer
toward any part of the body or at other
people or animals.
Always turn the compressor off and
bleed pressure from the air hose and tank
before attempting maintenance, attaching
tools or accessories.

WARNING: Risk of Electrical Shock
What Could Happen
Your air compressor is powered by
electricity. Like any other electrically
powered device, If it is not used
properly it may cause electric shock.
Repairs attempted by unqualified
personnel can result in serious injury
or death by electrocution.
Electrical Grounding: Failure to provide
adequate grounding to this product
could result in serious injury or death
from electrocution.
See grounding instructions.
How To Prevent It
Never operate the compressor outdoors
when it is raining or in wet conditions.
Never operate compressor with
protective covers removed or damaged.
Any electrical wiring or repairs required
on this product should be performed by
authorized service center personnel
in accordance with national and local
electrical codes,
Make certain that the electrical circuit
to which the compressor is connected
provides proper electrical grounding,
correct voltage and adequate fuse
protection.

WARNING: Risk to Breathing
What Could Happen
The compressed air directly from your
compressor is not safe for breathing.
The air stream may contain carbon
monoxide, toxic vapors, or solid
particles from the tank. Breathing these
contaminants can cause serious injury
or death.
Sprayed materials such as paint, paint
solvents, paint remover, insecticides,
weed killers, may contain harmful
vapors and poisons.
How To Prevent It
Air obtained directly from the compressor
should never be used to supply air for
human consumption. In order to use air
produced by this compressor for breathing,
suitable filters and in-line safety
equipment must be properly installed.
In-line filters and safety equipment
used in conjunction with the compressor
must be capable of treating air to all
applicable local and federal codes prior
to human consumption.
Work in an area with good cross
ventilation. Read and follow the safety
instructions provided on the label or
safety data sheets for the materials
you are spraying. Use aNIOSH/MSHA
approved respirator designed for use with
your specific application.

operator.
How To Prevent It
Always operate compressor in astable
secure position to prevent accidental
movement of the unit. Never operate
compressor on a roof or other elevated
position. Use additional air hose to
reach high locations.

CFM: Cubic feet per minute.
SOFM: 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.
This unit is capable of powering the following Accessories. The accessories are
available through the current Power and Hand Tool Catalog or full-line Sears
stores.

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.
