You have purchased an air compressor unit consisting
of aone cylinder, single-stage air compressor pump
and air tank. Included are wheels, regulator, gauges,
and handle.
This air compressor requires no oil. Now you can
enjoy all the benefits of having an air compressor
without ever having to purchase, add or change oil.
Your air compressor can be used for operating paint
spray guns, air tools, air brushes, or inflating tires and
plastic toys, spraying weed killers, insecticides, etc.
An air pressure regulator is required for most ofthe
applications.
An air filter which removes moisture and dirt from
compressed air should be used where applicable.
These accessories can be purchased from most Sears
stores or from the Sears Power Tool Catalog.
D20517 Rev. O 312100 6--ENG
Air Compressor Pump: To compress air, the piston
moves up and down in the cylinder. On the downstroke,
air is drawn inthrough the air intake valves. The exhaust
valves remain closed. On the upstroke of the piston, air
is compressed. The intake valves close and com-
pressed air is forced out through the exhaust valves,
through the outlet tube, through the check valve and 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.
Check Valve: When the aircompressor is operating, the
check valve is"open", allowing compressed air to enter
the air tank. When the air compressor reaches"cut-out"
pressure, the checkvalve"closes", allowing air pressure
to remain inside the air tank.
Pressure Release Valve: (if equipped) 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. If
the air is not released, the motor will not be able to start.
The pressure release valve allows the motor to restart
freely. When the motor stops running, air will be heard
escaping from the valve for afew seconds. No air should
be leaking when the motor is running.
Pressure Switch: The pressure switch automatically
starts the motor when the air tank pressure drops below
the factoryset"cut-in" pressure. Itstops the motor when
the air tank pressure reaches the factory set "cut-out"
pressure.
Safety Valve: Irthe pressure switch does not shut offthe
air compressor at its cut-out pressure setting, the safety
valve will protect the tank against high pressure by
"popping out" at its factory set pressure (slightly higher
than the pressure switch cut-out setting).
Regulator: The air pressure coming from the airtank is
controlled by the regulator. Turn the regulator knob
clockwise to increase pressure and counter-clockwise to
decrease pressure. To avoid minor readjustment after
making a change in pressure setting, always approach
the desired pressure from a lower pressure. When
reducing from a higher to a lower setting, first reduce to
some pressure less than that desired, then bring up tothe
desired pressure. Depending onthe airrequirements of
each particular accessory, the outlet regulated air pres-
sure may have to be adjusted while operating the
accessory.
Outlet Pressure Gauge; The outlet pressure gauge
indicates the air pressure available at the outlet side of
the regulator. This pressure is controlled bythe regulator
and is always less or equal to the tank pressure. See
"Operating Procedures".
Tank Pressure Gauge: The tank pressure gauge indi-
cates the reserve air pressure in the tank.
Cooling System: This compressor contains an ad-
vanced design cooling system. Atthe heart ofthis cooling
system isanengineered fan. It isperfectly normal for this
fan to blow air through the vent holes inlarge amounts.
You know that the cooling system isworking when airis
being expelled.

PORT FOR PULLING THE UNIT UP AND DOWN
STAIRS OR STEPS. THE UNIT MUST BE LIFTED,
OR PUSHED UP A RAMR
Attach the handle to the compressor saddle by
inserting the handle inside the compressor saddle
and lining up the bolt holes on each side. Install the
two screws, one on each side. Tighten securely.
It will be necessary to brace or support one side
of the outfit when installing the wheels because
the compressor will have a tendency to tip over.
2. Install one shoulder bolt and one nut for each wheel.
Tighten securely. The outfit will sit level ifthe wheels
are properly installed.
3.
Clean and dry underside of air tank leg opposite
wheels. Remove the protective strip from the adhe-
sive backed molded foot bumpers. Attach the foot
bumpers to the bottom of leg on each end. Press
firmly into place.
Location of the Air Compressor
Locate the air compressor in a clean, dry and well
_entilated area. The aircompressor should be located at
least12" away from the wall or other obstructions thatwill
interfere with the flow of air, The air compressor pump
and shroud are designed to allow for propercooling. The
ventilation openingson the compressor are necessary to
maintainproper operating temperature. Donotplace rags
or other containers on or near these openings.
Lubrication and Oil
This unit needs nolubrication or oiling.
ExtensionCords
Useextraair hoseinstead ofan extension cord to avoid
voltagedropandpowerlossto themotor,andtoprevent
overheating,
If an extension cord must be used, be sure it is:
• a 3-wire extension cord that has a 3-blade ground.
ing 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 your Parts List Manual for thevoltage and circuit
protection requirements ofyour compressor. Use only a
fuse or circuit breaker that is the same rating as the
branch circuit the air compressor is operated on. If the
compressor is connected to
a circuit protected by fuses, use only dual element time
delay fuses, as noted in that Service Bulletin.
Referto Parts List Manual for your compressor. Certain air
compressor models can be operated on a 15 amp circuit
if:
1. Voltage supply to circuit is normal.
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.
If any of the above conditions cannot be met, or if
operation of the compressor repeatedly causes interrup-
tion of the power, it may be necessary to operate it from
a 20 amp circuit. It is not necessary to change the cord
set.

Grounding Instructions
RISK OR ELECTRICAL SHOCK. In the event of a
short circuit,groundingreduces the riskof shock
by providing an escape wire for the electric
current. Thisair compressor must be properly
grounded.
The portable air compressor isequipped with acord
having a grounding wire with an appropriate grounding
plug. The plug must be used with an outlet that has
been installed and grounded in accordance with all
local codes and ordinances. The outlet must have the
same configuration as the plug. DO NOT USE AN
ADAPTER TO DEFEAT THE GROUNDING FEATURE
OF THE PLUG.
Inspect the plug and cord before each use. Do not
use if there are signs of damage.
IMPROPER GROUNDING CAN RESULT IN
ELECTRICAL SHOCK,
Do not modify the plug that has been provided. If it
does not fitthe available outlet, the correct outlet
should be installedby a qualifiedelectrican.
If repairing cord or plug, the grounding wire must be
kept separate from the current-carrying wires. Never
connect the grounding wire to a flat blade plug termi-
nal. The grounding wire has insulation with an outer
surface that is green - with or without yellow stripes.
Ifthese grounding instructions are not completely
understood, or if in doubt as to whether the compres-
sor is properly ground-ed, have the installation
checked by a qualified electrician.
