Cut-Out Pressure: When you turn onyouraircompres-

sorand itbegins torun, air pressure intheairtank 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 pres-

sure at which the motor shuts off is called "cut-out

pressure."

Cut-In Pressure: While the motor is off, air tank pres-
suredrops as you continueto useyour accessory.When

the tank pressure drops to a certain low level the motor
willre-start automatically. The low pressureat whichthe

GENERAL INFORMATION

You have purchased an air compressor unit consisting

of atwo cylinder, single stage air compressor pump, an
ASME air tank, associated controls and instruments.

This air compressor must be permanently mounted in

place.

Your air compressor can be used for operating paint

spray guns, air tools, caulking guns, grease guns, air
brushes, sandblasters, inflating tires and plastic toys,

DESCRIPTION OF OPERATION

Air Compressor Pump: To compress air, the pistons

move upand down inthecylinders. On the downstroke,
air is drawn in through the air intake filter and then
through theair intakevalves. The exhaust valve remains

closed. On the upstroke of the piston, air is com-

pressed. The intakevalves close and compressed air is

forced outthroughthe exhaust valves, throughtheoutlet
tube, through the check valve and into the air tank.
Working air is not available until the compressor has

raised air tank pressure above that required at the air

outlet.

Check Valve: When the air corn pressor isoperating, the

check valve is "open," allowing compressed air to enter

the airtank. When the aircompressor reaches "cut-out"

pressure, the check valve "closes," allowing air pres-

sure to remain inside the air tank. If the air is not

unloaded, the motor will try to start, but will beunable to.

The check valve allows the motor to re-start freely.

spraying weed killers, insecticides, etc. An air pressure

regulator is usu ally necessary for most of these applica-

tions. Regulators can be purchased from most Sears

stores orthrough the current Sears Power and Hand Tool
Catalog.

Separate airtransformers which combine the functions
of air regulation and/or moisture and dirt removal should

be used where applicable.

Some form of piping or shut-off valve must be installed

before operating the aircorn pressor. A 1/2" NPTshut-off

globe valve should be installed at the air compressor
tank. Do not use a ball valve.

Pressure Switch: The pressure switch automatically
starts

the motor when the air tank pressure drops below the
factory set "cut-in" pressure. Itstopsthe motorwhen the

air tank pressure reaches the factory set "cut-out"
pressure.

Pressure Release Valve: The pressure release valve is

designed to automatically release compressed airfrom
the compressor head and the outlet tube when the air
compressor reaches "cut-out" pressure or isshut off. If
tt_eair isnot released, the motor willtry to start but will

be unable to. The pressure release valve allows the
motorto restart freely. When the motor stops running, air

will be heard escaping for a few seconds. No airshould

be heard leaking when the motor is running.

Safety Valve: Ifthe pressureswitch does not shut offthe
air compressorat ornearitscut-out pressuresetting,the

safety valve willprotect against high pressureby "pop-

ping out" at itsfactory set pressure (slightlyhigher than

the pressureswitch cut-out setting).

INSTALLATION AND BREAK-IN PROCEDURES

Location of the Air Compressor

Operate the air compressor in a clean, dry and well

ventilated area. The air intake filter must be kept clear of

obstructions which could reduce air delivery of the air

compressor. The air compressor should be located at

least 12" away from walls or other obstructions that
could interfere with the flow of air th rough the fan bladed

flywheel. The air compressor crankcase and head are

designed with fins to provide proper cooling. If the
humidity is high, a Sears air filter can be installed to

remove excessive moisture.

The air compressor should be as near to air outlets as

possible in order to avoid long pipe lines. Do not place

the air compressor where heat is excessive.

hole. (It must not be allowed to be lower than 3/8" - 6
threads down -from the top .)When filling the crankcase,

the oil flows very slowly. If the oil is added too quickly,

it will overflow and appear to be full. (Crankcase oil
capacity is 16 fluid ounces.) Under winter-type condi-
tions use SAE 10W oil. (Multi-viscosity oil - 10W30 - will
leave carbon deposits on critical components reducing

performance and compressor life.) Replace oil fill plug.

t._ SCREW

(NOTSUPPUED)

1. The air compressor must be bolted to the floor.
Bolting holes are provided in the base feet.

2. Mount the air compressor on a solid level founda-

tion with no strain to the air tank feet. Solid shims

may be used if necessary.

Piping

Plastic or PVC pipe is not designed for use with
compressed air. Regardless ofits indicated pres-
sure rating, plastic pipe can burst from air pres-
sure. Use only metal pipe for air distribution lines.

If a pipe line isnecessary, use pipe that is the same size
asthe air tank valve. Piping that is too small will restrict

the flow of air. Ifpiping isover 100 feet long, use the next

larger size. Bury underground lines below the frost line
and avoid pockets where condensation can gather and

freeze. Apply pressure before "underground lines are
covered to make sure all pipe joints are free of leaks.

Wiring Instructions

IMPROPER GROUNDING CAN RESULT IN ELEC-
TRICAL SHOCK. WIRING OF THE PRESSURE

SWITCH, ELECTRIC MOTOR AND MANUAL ON/
OFF SWITCH SHOULD BE DONE BYA LICENSED

ELECTRICIAN IN ACCORDANCE WITH NA-
TIONAL AN D LOCAL CODES AND ORDINANCES.

To prevent added current draw and motor overheating

we recommend the use of 12 gauge (AWG) wire, not
exceeding a 70 foot length. The wire must be rated at a

minimum temperature of 75° C.

When connecting wires, make sure that: (1)the electrical

box is large enough; (2)service is ofadequate amperage
rating; (3)the supply line has the same electrical charac-
teristics (voltage, cycles and phase) asthe motor;, (4)the
line wire isthe proper size and (5) no other equipment is
operated from the same line. Various national and local
codes and standards have been set up covering elec-
trical apparatus and wiring. These should be consulted

and observed. Our recommended wire sizes may be
smaner than the minimum set up by local ordinances. If
so, the larger size wire should be used to prevent
excessive linevoltage drop. Forwiring instructions, see
the diagram inside the pressure switch cover.

Break-In Procedures

Sedous damage may result if the following
break*in instructions are not closely followed.

This procedure is required only once; before the air
compressor is put into service. Some form of piping or

shut-off valve must be installed before beginning the
break-in procedure. A 1/2" NPT shut-off globe valve
should be installed at the air compressor tank. Do not

use a ball valve.

1.

Recheck compressor wiring. Make sure wires are
secure at allterminal connections. Free all contacts.
of loose wire cuttings, etc.

2.

Check oil level in the crankcase before operation.
The oil level should be even with the top of the fill

hole and must not be allowed to be lower than 3/8"

(six threads down) from the top at any time. Add oil

if level is low.

OPERATING PROCEDURES

3. Open the shut-offvalve fully, to permit air toescape
and to prevent pressure build-up in the air tank.

4. Turn ON the air compressor.

5. Run the air compressor for 30 minutes to seal the
rings and lubricate all internal surfaces.

6. Check all air line fittings and connections/piping for
air leaks by applying a soap solution. Correct as

necessary. Even minor leaks can cause this air
compressor to overwork, resulting in premature

break-down or inadequate performance.

7. Check for excessive vibration and noise. Adjust air
compressor belt guard as necessary to eliminate

chatter. Re-adjust or shim the air compressor feet,

if necessary for proper level.

8. Close the shut-off valve and let the air compressor

pump up to cut-out pressure. Turn the aircompres-

sor off and check oil level. Add oil if necessary.

Connect the air hose to the air outlet adapter.

Your compressor is now ready for use.

1. Before attaching an air hose or accessory, make
sure the pressure switch OFF/AUTO lever is in the
"OFF" position.

2. Attach hose and accessory.

TOO MUCH AIR PRESSURE CAUSES A HAZ-
ARDOUS 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.

MAINTENANCE

TROUBLESHOOTING GUIDE

UNIT CYCLES AUTOMATICALLY WHEN POWER IS ()N. WHEN DOING MAINTENANCE, YOU MAY BE
EXPOSED TO VOLTAGE SOURCES, COM PRESSED AIR OR MOVING PARTS. PERSONAL INJURIES CAN

OCCUR. BEFORE PERFORMING MAINTENANCE OR REPAIR, TURN OFF AND LOCK OUT ELECTRIC

POWER AND BLEED OFF AIR TAN K PRESSURE. NEVER OPERATE TH ECOMPRESSOR WITH THE BELT
GUARD REMOVED.

Pulley and Flywheel - Alignment

The compressor flywheel and motor pulley must be
inline (in the same plane) within 1/16" to assure belt

retention within sheave grooves. The motor mounting
holes on the saddle are skewed to square the motor with
the compressor mounting hole as the belt is tensioned.
To check alignment, disconnect electrical power and

remove the belt guard. Place a straightedge against the

outside of the flywheel and measure the distance from

it to the nearest groove. Alignment is achieved when the

other end of the straightedge is within 1/16" of the

measured dimension at the pulley grooves. Squareness
is achieved when the pulley grooves are an equal
distance from the straightedge on both sides of the

motor shaft.
