To compress air, the pistons move up and down in the
Cylinder. On the downstroke, air is drawn in through the
air intake valve. The exhaust valve remains closed. On
the upstroke of the piston, air is compressed. The intake
valves close and compressed air is forced out through
the exhaust valve, 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
Ithe air outlet. Since Ihe air tank pressure is usually

-VENT OF A SHORT CIRCUIT, GROUNDING
R-:)UCES
THE RISK OF SHOCK BY PROVIDING AN 5SCAPE WIRE FOR THE ELECTRIC CURRENT, THIS COMPRESSOR MUST
BE PROPERLY GROUNDED.
READ THE
FOLLOWING iNSTRUCTIONS.
1. The compressor is equipped with a cord having a
grounding wire with an appropriate grounding plug.
The plug must be used with an outlet that has been
properly 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.
2, If repair or replacement of the cord or plug is ever
necessary, do not connect the grounding wire to
either flat blade terminal. (The grounding wire has
insulation with an outer surface that is green- with or
without yellow stripes.)
3. Do not modify the plug that has been provided, If it
does not fit the available outlet, the correct outlet
should be installed by a qualified electrician.
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 or serviceman.
All units are shipped without oil. Serious
damage may result if the following break-in
instructions are not closely followed. This
operation has to be completed only once
when first putting the unit in service,
PlaCe unit on a level surface. Remove oil fillplug (51) and
slowly add a special compressor oil such as Sears
9H6426 or SAE 20=20W SF motor oil until it is even with
the top of the oil fill hole. When filling the crankcase, the
oil flows into itvery slowly. If the oil is added too quickly,it
will overflow and appear to be full. (It takes 16 fluid
ounces of oil ot fill the crankcase.) Under winter-type
conditions use SAE 10W oil. Multi-viscosity oil (10W30)
may be used but will result in carbon deposits on critical
components and reduce performance and compressor
life. Replace oil fill plug (51). Plug the compressor into
the correct power source. Start the compressor by
switching the ON-AUTO/OFF
switch (19) to the ONAUTO position. Turn the regulator knob (23) clockwise
fully to permit air to escape and prevent air pressure
bui!dup in the air tank. RUN THE COMPRESSOR 30
MINUTES IN THIS MANNER TO LUBRICATE PISTONS AND BEARINGS. Shut off air with regulator knob
(turn counterclockwise) and let the unit pump up to cut
off pressure. Turn the switch to "OFF" and check the oil
level; add oil if necessary, Turn switch to _ON" and the
unit is ready for use. Connect the air hose to the air outlet
connection (27) located on the front of the console.
Refer to Figure 1.
OPERATION
Control Console
The control console (33) is located on the front of the
unit. The air pressuro coming from the air tank is controlled by the regulator knob (23). Turn the regulator knob
clec_ise to increase pressure and countemlockwise 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 to
the desired pressure. Depending on the air flow requirements of each particular accessory, the outlet regulated
air pressure might have to be adjusted under flow conditions, Also on the console is the ON-AUTO/OFF switch,
air outlet, safety valve and two pressure gauges. One
gauge shows the air tank pressure and the other the
outlet regulated pressure. Refer to Figure 2.

Avoid using long extension cords. They can
cause a power loss to the motor, Add extra air
hose instead of extension cords.
If an extension cord must be used:
- use only 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.
- make sure the cord is in good condition.
WARNING
- the cord should bend longer than 50 feet.

Pressure Release Valve
The pressure release valve located on the side of the
pressure switch is designed to unload air from the compressor head automaUcally al unit shut off. This protects
the motor from starting against air pressure remaining in
the compressor head and tubing. When the motor stops
running, air will be heard escaping from the valve for a
few seconds. When the motor is running, no air should
be leaking from the pressure release valve.

with oil will cause premature
compressor failure. Do not overfill,
Check oil level in the crankcase before each use. The oil
level should be even with the top of the fill hole and must
not be allowed to be lower than _/8" from the top (6
threads down from the top) at any time. It is recommended that the oil in the base (52) be changed after
every 100 hours of operation. Todrain the oil, remove the
oil drain plug (51) and collect the oil in a Suitable container. Be sure to replace the plug securely before
adding new oil. Use a special compressor oil, such as
Sears 9-16426 or SAE 20-20W SF motor oil (crankcase
oil capacity is 16 fluid ounces). Under extreme winter
conditions use SAE 10W oil,
Location of Air Compressor
Locate the unit in a dry, clean, cool and well ventilated
area. The compressor crankcase and head are
designed with fins which allow for proper cooling: Clean
or blow off fins and any other parts of the compressor
that collect dust Ordirt. A clean compressor runs cooler
and provides longer service. Do not place rags, contain_
ers or other material on or against the console which
would obstruct ventilation openings necessary for prop:
er compressor operating temperature. If humidity is
high, a Sears Air Filter can be installed on the air outlet
adapter to remove excess moisture. Follow the instruclions packaged with the air filter for proper installation.
