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.
This unit is capable of powering the following Accessories. The accessories are
available through the current Power and Hand Tool Catalog or fuU-line Sears
stores.

HOW TO SET UP YOUR
UNIT
Location of the Air Compressor
Locate the air compressor in aclean,
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,The air filter must be kept
clear of obstructions which could
reduce air flow to the air compressor.
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 appr0pdate
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 agrounding 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.
.
4,
Make sure the outlet being used
has the same configuration as
the grounded plug. DO NOT
USE AN ADAPTER. See
illustration.
Grounded
_Outlets
Inspect the p,lug 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 propedy
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,
11-t=NG D24580

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 extension cords
attach extra air hoses to each other
starting at the air outlet.
Jf an extension cord must be used,
be sure it is:
Qa 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 AWG and 8 AWG
may also be used. DO NOT USE
14 OR 16 AWG.)
Voltage and Circuit Protection
Refer to the specification table 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.
.
.
4.
Circuit is not used to supply any
other electrical needs (lights,
appliances, etc.).
Extension cords comply with
specifications.
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 a20
amp circuit. It is not neoessary 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 vanous controls and adjustments. Save this manual for future
reference.
Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/G.
Switch
Safety
Valve
Tank
Pre,_sure
Gauge
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.
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator; 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.
On/Auto/Off Switch: 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: 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).
The drain
is located at
the base of the Drain
air tank and is Valve
used to drain
condensation at the end of each use.
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 (net 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.
13- ENG D24580

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-our' pressure, the check
valve "closes", allowing air pressure
to remain inside the air tank.
Pressure Release Valve: 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 after the unit
reaches "cut-out" pressure.
Air Intake Filter (not shown); 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".
Motor Overload Protector:. The
motor has an automatic reset 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 clown before restarting. The
compressor will automatically restart
after the motor cools.
If the overload protector shuts the
motor off frequently, check for a
possible voltage problem, Low
voltage can also be suspected when:
1. The motor does not get up to full
power or speed.
2, Fuses blow out when starting
the motor; lights dim and remain
dim when motor is started and is
running.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to
"OFF".
Before First Start Up:
Serious damage
may result if the
following break-in instructions are
not closely followed,
This procedure is required before the
air compressor is put into service and
when the check valve or a complete
compressor pump has been
replaced.
1. Make sure the On/Auto/Off lever
is in the "OFF" position.
NOTE: If quick connect is installed,
pull coupler back until it clicks to
prevent air from escaping through the
quick connect.
2. Plug the power cord into the
correct branch cimuit receptacle.
(Refer to Voltage and Circuit
Protection paragraph in the
Installation section of this
manual.)
3. Open the drain valve fully
(counterclockwise) to permit air

Pull regulator knob out, turn
counterclockwise until it stops.
Push knob in to lock in place.
Attach hose and accessodes.
NOTE: The hose or accessory
will require a quick connect plug
if the air outlet is equipped with a
quick connect.
_Too much air
pressure causes a
hazardous risk of bursting. Check
the manufacturer's maximum
pressure rating for air tools and
accessories. The regulator outlet
pressure must never exceed the
maximum pressure rating.
How to Start:
1. Turn the OnlAuto/Off lever to
"AUTO" and allow tank pressure
to build. Motor will stop when
tank pressure reaches "cut-out"
pressure.
2. Pull the regulator knob out and
turn clockwise to increase
