ACCESSORIES FOR USE WITH SEAR AIR COMPRESSORS

7 — Eng D20410
Youhavepurchased an air compressor unit consisting of
a two cylinder, single stage air compressor pump, an
ASMEair tank, associatedcontrolsandinstruments. 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,
spraying weed killers, insecticides, etc. An air pressure
regulator is usually necessary for most of these applica-
tions. Regulators can be purchased from most Sears
storesor through the current Sears Power andHandTool
Catalog.
Separateair transformers whichcombinethe functions of
airregulationand/ormoistureanddirtremovalshouldbe
used where applicable.
Some form of piping or shut-off valve must be installed
beforeoperatingtheaircompressor.A1/2"NPTshut-off
globe valve should be installed at the air compressor
tank. Do not use a ball valve.
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
least12" away from wallsorother obstructions that could
interfere with the flow of air through 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
possiblein order to avoid longpipelines.Do not place the
air compressor where heat is excessive.
Pressure Switch: The pressure switch automatically
starts
the motor when the air tank pressure drops below the
factoryset"cut-in"pressure.Itstopsthemotorwhenthe
air tank pressure reaches the factory set "cut-out"
pressure.
Pressure Release Valve: The pressure release valve 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 try to start but will
be unable to. The pressure release valve allows the
motortorestartfreely.Whenthemotorstopsrunning,air
will be heard escaping for a few seconds. No air should
be heard leaking when the motor is running.
SafetyValve: If the pressure switch does not shut off the
aircompressoratornear its cut-out pressure setting, the
safety valve will protect against high pressure by "pop-
ping out" at its factory set pressure (slightly higher than
the pressure switch cut-out setting).
Air Compressor Pump: To compress air, the pistons
move up and down in the cylinders. On the downstroke,
airisdrawn in through the air intakefilterandthenthrough
the air intake valves. 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 valves, through the outlet 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 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. If the air is not unloaded, the
motor will try to start, but will be unable to. The check
valve allows the motor to re-start freely.

EXCESSIVE VIBRATION MAY WEAKEN THE
AIR TANK AND CAUSE AN EXPLOSION.
THE OUTFIT MUST BE MOUNTED AS
DESCRIBED AND ILLUSTRATED BELOW.
Piping
Plastic or PVC pipe is not designed for use
with compressed air. Regardless of its
indicated pressure rating, plastic pipe can
burst from air pressure. Use only metal pipe
for air distribution lines.
If a pipe line is necessary, use pipe that is the same size
as the air tank valve. Piping that is too small will restrict
the flow of air. If piping is over 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.
Lubrication and Oil
Compressors are shipped without oil. Do not attempt to
operate this air compressor without first adding oil to the
crankcase.
Place unit on a level surface. Remove oil fill plug and
slowly add a special compressor oil such as Sears 9-
16426orSAE-20-20W SF motor oil until itisevenwiththe

Bolting holes are provided in the base feet.
2. Mountthe air compressor onasolid level foundation
with no strain to the air tank feet. Solid shims may
be used if necessary.
top of the oil fill hole. (It must not be allowed to be lower
than3/8"- 6 threads down - from the top.) Whenfillingthe
crankcase,the oil flows very slowly. If theoilis 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.
Wiring Instructions
IMPROPER GROUNDING CAN RESULT IN
ELECTRICAL SHOCK. WIRING OF THE
PRESSURE SWITCH, ELECTRIC MOTOR
AND MANUAL ON/OFF SWITCH SHOULD
BE DONE BY A LICENSED ELECTRICIAN
IN ACCORDANCE WITH NATIONAL AND
LOCAL CODES AND ORDINANCES.
Toprevent addedcurrentdraw and motoroverheatingwe
recommendtheuse of 12 gauge (AWG) wire, notexceed-
inga 70 foot length. The wire must be ratedataminimum
temperature of 75oC.
Whenconnecting wires, make sure that: (1)theelectrical
box is large enough; (2) service is of adequate amperage
rating; (3) the supply line has the same electrical charac-
teristics (voltage, cycles and phase) as the motor; (4) the
line wire is the 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 electri-
calapparatusand wiring. These should be consulted and
observed. Our recommended wire sizes may be smaller
than the minimum set up by local ordinances. If so, the
larger size wire should be used to prevent excessive line
voltage drop. For wiring instructions, see the diagram
inside the pressure switch cover.
Electrical wiring must be located away from hot surfaces
such as the compressor head, compressor cylinder or
compressor outlet tube.

Break-In Procedures
Serious damage may result if the following
break-in instructions are not closely fol-
lowed.
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
secureatallterminalconnections.Freeall 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.
3. Opentheshut-offvalvefully,topermitairtoescape
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. Checkallairlinefittingsandconnections/pipingfor
air leaks by applying a soap solution. Correct as
necessary. Even minor leaks can cause this air
compressor to overwork, resulting in premature
break-downor 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
pumpuptocut-out pressure. Turn the air compres-
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
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.
Serious damage may result if the following
break-in instructions are not closely fol-
lowed. Compressed air from the outfit may
contain water condensation and oil mist.
Do not spray unfiltered air at an item that
could be damaged. Some air operated tools
or devices may require filtered air. Read the
instructions for the air tool or device.
3. Turn the compressor on and allow tank pressure to
build. The motor will stop when tank pressure
reaches cut-out pressure.
Your outfit is ready for use.
Air Compressor
A clean air compressor runs cooler and provides longer
service. Clean or blow off fins and any other parts of the
aircompressorthat collect dust or dirt. Do not place rags,
containers or other material on or against the ventilation
openings in the belt guard. Adequate ventilation is nec-
essary to maintain proper air compressor operating
temperature.
Air Filter - Inspection and
Replacement
NOTE
Keep the air filter clean at all times. Do not
operate the compressor with the air filter
removed.
TOO MUCH AIR PRESSURE CAUSES A HAZARDOUS RISK OF BURSTING. CHECK THE
MANUFACTURER'S MAXIMUM PRESSURE RATING FOR AIR TOOLS AND ACCESSORIES. THE

A dirty air filter will not allow the compressor to operate
at full capacity. Before you use the compressor, check
the air filter to be sure it is clean.
If it is dirty, remove the screws and filter retainer. Pull out
the filter, replace with new.
Oil - Checking and Changing
Overfilling with oil will cause premature
compressor failure. Do not overfill.
Checkoillevel in the crankcase daily. The oil level should
be even with the top of the fill hole and must not be
allowed to be lower than 3/8" from the top (6 threads) at
anytime.Itisrecommendedthat the oil be changed after
every100hoursofoperation.Todraintheoil,removethe

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 10
weight oil.
Air Tank - Draining Water
WATER WILL CONDENSE IN THE AIR
TANK. IF NOT DRAINED, THE WATER WILL
CORRODE AND WEAKEN THE AIR TANK
CAUSING A RISK OF AIR TANK RUPTURE.
Watershould be drained from the air tank after each use.
Operate the unit to apply 15-20 PSIG and open the drain
cock. Continue operating unit until all moisture is re-
moved from the air tank. Close the drain cock tightly.
NOTE
If drain cock valve is clogged, release air
pressure in air tank. The drain cock valve
can then be removed, cleaned and rein-
stalled.
Check Valve - Inspection and
Replacement
Remove the check valve for inspection or replacement if
air tank pressure will not build up. Use the following
procedure to inspect, clean or replace the check valve.
1. Release air pressure from the air tank.
2. Loosen the top and bottom nuts and remove the
outlet tube.
3. Unscrew the check valve (turn counterclockwise)
using a 7/8" diameter 1/2" socket wrench.
4. Check that the valve disc moves freely inside the
check valve and that the spring holds the disc in the
upper, closed position. The check valve may be
cleaned with a solvent.
5. Apply sealant to the check valve threads.Reinstall
the check valve (turn clockwise). The valve stem
should still move freely do not over tighten.
6. Replace the outlet tube and tighten top and bottom
nuts.
Safety Valve - Inspection
IF THE SAFETY VALVE DOES NOT WORK
PROPERLY OVER-PRESSURIZATION MAY
OCCUR, CAUSING AIR TANK RUPTURE
OR EXPLOSION. OCCASIONALLY PULL
THE RING ON THE SAFETY VALVE TO
MAKE SURE THAT THE SAFETY VALVE
OPERATES FREELY. IF THE VALVE IS
STUCK OR DOES NOT OPERATE
SMOOTHLY, IT MUST BE REPLACED WITH
THE SAME TYPE OF VALVE.
Motor
The motor has a thermal overload protector. If the motor
overheatsforanyreason,theoverloadprotectorwillshut
off the motor. The motor must be allowed to cool down
before restarting. De-energize power supply. To restart,
depress the reset button located on the end of the motor
and energize the power supply.
NOTE
If the overload protector shuts the motor
off frequently, check for a possible voltage
problem. Low voltage can also be sus-
pected when:
1. the motor does not get up to full power
or speed;
2. fuses blow out when the motor is
started;
3. lights dim when motor is started and
remain dim while it is running.
Belt - Replacement
SERIOUSINJURY OR DAMAGEMAY OCCUR IFPARTS OF
THE BODY OR LOOSE ITEMS GET CAUGHT IN MOVING
PARTS. NEVER OPERATE THE COMPRESSOR WITH THE
BELT GUARD REMOVED. THE BELT GUARD SHOULD BE
REMOVED ONLY WHEN THE POWER TO THE COMPRES-
SOR IS DISCONNECTED.
The motor is mounted on an adjustable motor base.
To replace belt:
1. Turn off and lock out power source.
2. Remove screws from the back of the belt guard.
3. Loosen the four motor mounting screws.
4. Slide the motor toward the compressor pump.
5. Remove belt and replace.

belt deflection measured midway between the pul-
ley and flywheel when a 3 pound weight or equiva-
lent finger pressure is applied at this point. A loose
belt will squeal at compressor start-up.
7. Replace beltguard and screws.
Pulley and Flywheel - Alignment
Thecompressorflywheelandmotor pulley must be inline
(in the same plane) within 1/16" to assure belt retention
withinsheavegrooves.The motor mounting holes on the
saddle are skewed to square the motor with the com-
pressor mounting hole as the belt is tensioned. To check
alignment, disconnect electrical power and remove the
beltguard. Place a straightedgeagainsttheoutside 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 straight-
edge on both sides of the motor shaft.
