__ RISK TO BREATHING (ASPHYXIATION)
WHAT CAN HAPPEN HOW TO PREVENT IT
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
air tank. Breathing these contami-
nants can cause serious injury or
death.
Air obtained directly from the com-
pressor 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 compres-
sor must be capable of treating air
to all applicable local and federal
codes prior to human consump-
tion.

__ RISK OF BURSTING
Air Tank: On February 26, 2002, the U.S. Consumer Product Safety Commission
published Release # 02-108 concerning air compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life is dependent
upon several factors, some of which include operating conditions, ambient con-
ditions, proper installations, field modifications, and the level of maintenance.
The exact effect of these factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the
inner wall of the air receiver tank can cause the air tank to unexpectedly rupture
allowing pressurized air to suddenly and forcefully escape, posing risk of injury
to consumers.
Your compressor air tank must be removed from service by the end of the year
shown on your tank warning label.
The following conditions could lead to a weakening of the air tank, and result in
a violent air tank explosion:
WHAT CAN HAPPEN
• Failure to properly drain condensed
water from air tank, causing rust
and thinning of the steel air tank.
• Modifications or attempted repairs
to the air tank.
Unauthorized modifications to
the safety valve or any other
components which control air tank
pressure.
HOW TO PREVENT IT
Drain air tank daily or after each
use. If air tank develops a leak,
replace it immediately with a
new air tank or replace the entire
compressor.
Never drill into, weld, or make any
modifications to the air tank or its
attachments. Never attempt to
repair a damaged or leaking air
tank. Replace with a new air tank.
The air tank is designed to
withstand specific operating
pressures. Never make adjustments
or parts substitutions to alter the
factory set operating pressures.
5 - ENG

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.
Tires:
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.
Over inflationof tires could result in
serious injury and property damage. • Use a tire pressure gauge to check the tires pressure before each use
and while inflating tires; see the tire
sidewall for the correct tire pressure.
NOTE: Air tanks, compressors and
similar equipment used to inflate tires
can fill small tires very rapidly. Adjust
3ressure regulator on air supply to
no more than the rating of the tire
3ressure. Add air in small increments
and frequently use the tire gauge to
3revent over inflation.

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 auto-
matically. The low pressure at which
the motor automatically restarts is
called "cut-in" pressure.
Cut-Out Pressure: When an air com-
pressor 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 automati-
cally 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 elec-
tricity 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.

Unpacking
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" (30.5 cm)
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 ashort
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).
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 the same configuration as the
grounded plug. DO NOT USE AN
ADAPTER. See illustration.
_Grounded
_Outlets
3,
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 compres-
sor is properly grounded, have the
installation checked by a qualified
electrician.
RISK OF
-- ELECTRICAL
SHOCK. 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 elec-
trician.
10 - ENG

Extension Cords
If an extension cord must be used, be
sure it is:
• a3-wire extension cord that hasa
3-blade grounding plug, and a 3-slot
receptaclethat will accept the plug on
the product
• in good condition
• no longer than 50 feet
• 14 gauge (AWG)or larger.(Wiresize
increasesas gauge number decreas-
es. 12AWG and 10 AWG may also be
used. DO NOTUSE 16 OR 18 AWG.)
Risk of Property
Damage. The use
of an undersized extension cord
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.
Voltage and Circuit Protection
Refer to the specification chart for the
voltage and minimum branch circuit
requirements.
_Risk of Overheating.
-- Certain air
compressors can be operated on a 15
amp circuit if the following conditions
are met.
1. Voltage supply to circuit must
comply with the National
Electrical Code.
2. Circuit is not used to supply any
other electrical needs.
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 compres-
sor 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(I)/Off(O) Switch: Place this switch
in the On (I) position to provide
automatic power to the pressure
switch and Off (O) to remove power at
the end of each use.
Pressure Switch (not shown): 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: 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).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Outlet Pressure Gauge: 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.
Regulator: Controls the air pressure
shown on the outlet pressure
gauge. Turn regulator knob
clockwise to increase pressure
and counterclockwise to decrease
pressure.
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 until the
compressor has raised the air tank
pressure above that required at the air
outlet.
Drain Valve:
The drain valve
is located at Drain
the base of the Valve
air tank and is
used to drain condensation at the end
of each use.
12 - ENG

Check Valve: 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.
Motor Overload Protector (not
shown): The motor has a thermal
overload protector. If the motor
overheats for any reason, the overload
protector will shut off the motor. The
motor must be allowed to cool down
before restarting. To restart:
1. Set the On/Off lever to "Off" and
unplug unit.
2. Allow the motor to cool.
3. Plug the power cord into the
correct branch circuit receptacle.
