CFM: Cubic feet per minute.

SCFM: Standard cubic feet per minute; a unit of mea- sure of air delivery.

PSIG: Pounds per square inch gauge; a unit of measure of pressure.

ASME: American Society of Mechanical Engineers; made, tested, inspected and registered to meet the

standards of the ASME.

U.L. Listed: This product is Listed by Underwriters Laboratories, Inc. (UL). Samples of this product have been evaluated by UL and meet applicable UL Stan- dards 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 re-starts is called "cut-in pressure."

Cut-Out Pressure: When you turn on your air compres- sor and itbegins to run, air pressure inthe 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 pres-

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

GENERAL iNFORMATiON

You have purchased an air compressor unit consisting of a one 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, caulking guns, grease guns, air brushes, sandblaster, or inflating tires and plastic toys, spraying weed killers, insecticides, etc. An air pressure regulator is supplied for the applications.

An air filter which removes moisture and dirt from com- pressed air should be used where applicable.

These accessories can be purchased from most Sears stores or from the Sears Power Tool Catalog.

DESCRiPTiON OF OPERATION

Air Compressor Pump: To compress air, the piston moves up and down inthe cylinder. Onthe downstroke, air isdrawn 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.

CheckValve: When the air compressor isoperating, the check valve is"open", allowing compressed air to enter

the air tank. When the aircompressor reaches "cut-out" 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 com- pressor head and the outlet tube when the air compres- sor 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, airwill be heard escaping

from the valve for a few 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 factory set "cut-in" pressure. It stops the motor when the air tank pressure reaches the factory set "cut-

out" pressure.

SafetyValve: Ifthe 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 air tank 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 ap- proach 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 requirements of each particular accessory, the outlet regulated air pressure 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 by the regula- tor 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. 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.

ASSEMBLY

inserting the handle inside the compressor saddle and lining upthetwo bolt holes on each side. Install

the four screws, two 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 ten= dency to tip.

Install one shoulder bolt and one nut for each wheel.

Tighten securely. The outfit will sit level if the wheels

are properly installed.

Clean and dry underside of air tank leg opposite

wheels. Remove the protective paper strip from the adhesive backed rubber foot strip. Attach the rub-

ber foot strip to the bottom of leg. Press firmly into place.

iNSTALLATiON AND BREAK-iN PROCEDURES

Location of the Air Compressor

Locate the air compressor in a clean, dry and well ventilated area. The air 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 a wall or other obstructions that will interfere with the flow of air. The air compressor head and shroud are designed to allow for proper cooling.

Lubrication and Oil

This unit needs no lubrication or oiling.

Extension Cords

Use extra air hose instead of an extension cord to avoid voltage drop and power loss to the motor, and to prevent

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. 10AWG and 8AWG may also be used. DO NOT USE 14 OR 16 AWG.)

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 inter-

ruption of the power, it may be necessary to operate it

from a 20 amp circuit. It is not necessary to change the

cord set. 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 terminal. The

grounding wire has insulation with an outer surface that isgreen - with or without yellow stripes.

If these grounding instructions are not completely un- derstood, or ifin doubt as to whether the compressor is properly ground-ed, have the installation checked by a qualified electrician.

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.

Voltage and Circuit Protection

Refer to your Parts List Manual for the voltage and circuit protection requirements of your 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 isconnected to a circuit protected by fuses,

use only dual element time delay fuses. 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

The portable air 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

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.

Inspect the plug and cord before each use. Do not use

ifthere are signs of damage.

IMPROPER GROUNDING CAN RESULT IN

ELECTRICAL SHOCK.

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

electrican.

Break-in Procedure

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.

1. Set the pressure switch OFF/AUTO lever to the "OFF" position.

OPERATING PROCEDURES

2. Plug the power cord into the correct branch circuit receptacle.

3. Turn the regulator clockwise, opening itfully to prevent air pressure build-up in the tank.

4. Move the OFF/AUTO lever to "AUTO". The com-

pressor will start.

5. Run the compressor for 15 minutes. Make sure the regulator is open and there isno tank pressure build-

up.

6. After 15 minutes, close the regulator by turning it counterclockwise. The air tank will fill to cut-out

pressure and the motor will stop.

1. Before attaching air hose or accessories, make sure the OFF/AUTO lever is set to "OFF" and the air

regulator is closed.

2. Attach hose and accessories.

TOO MUCH AiR PRESSURE CREATES A HAZ- ARDOUS RiSK OF BURSTING. CAREFULLY FOL-

LOW STEPS 3 AND 5 EACH TiME THE COMPRES- SOR IS USED.

Compressed air from the unit may contain water condensation. 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.

Check the manufacturer's maximum pressure rat- ing for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating. If your compressor is not supplied with a regulator with gauge, install one before using

accessories.

Turn the OFF/AUTO lever to AUTO and allow tank pressure to build. Motor will stop when tank pres-

sure reaches "cut-out" pressure.

5. Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. Your

compressor is ready for use.

6. Always operate the air compressor in well-venti-

lated areas; free of gasoline or other solvent vapors.

7. Do not operate the compressor near the spray area.

When you are finished:

8. Set the OFF/AUTO lever to "OFF".

9. Turn the regulator counterclockwise and set the

outlet pressure to zero.

10. Remove the air tool or accessory.

11. Open the regulator and allow the air to slowly bleed from the tank. Close the regulator when tank pres-

sure is approximately 20 psi.

12. Drain water from air tank.

MAINTENANCE

UNiT CYCLES AUTOMATICALLY WHEN POWER iS ON. WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO VOLTAGE SOURCES, COMPRESSED AiR OR MOVING PARTS. PERSONAL iNJURiES CAN OCCUR. BEFORE PERFORM=

ING ANY MAINTENANCE OR REPAIR, UNPLUG THE COMPRESSOR AND BLEED OFF ALL AiR PRESSURE.

ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE DONE BY

OUAMFIED SERVICE PERSONNEL.

Air Filter =inspection and Replacement

Hot surfaces. Risk of burn. Compressor heads are exposed when filter cover is

removed. Allow compressor to cool prior to servicing.

Filter Retainer

Filter.

Keep the air filter clean at all times. Do not operate the compressor with the air filter removed.

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. Check Valve = Replacement

Before servicing:

• Unplug or disconnect electrical supply to compressor.

• Bleed tank of pressure.

• Allow compressor to cool.

Release all air pressure from air tank and unplug

unit.

Remove shroud.

Loosen the top and bottom nuts and remove the

outlet tube.

Remove the pressure release tube and fitting.

Unscrew the check valve (turn counterclockwise)

using a socket wrench.

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, such as paint and varnish

remover.

Apply sealant to the check valve threads. Reinstall the check valve (turn clockwise).

Replace the pressure release tube and fitting.

9. Replace the outlet tube and tighten top and bottom nuts.

10. Replace the shroud.

Safety Valve = inspection

ifthe safety valve does not work properly, over- pressurization may occur, causing air tank rup-

ture or an e×plosion. Before starting compres-

sor, pull the ring on the safety valve to make sure that the safety valve operates freely, ifthe

valve is stuck or does not operate smoothly, it must be replaced with the same type of valve.

Motor

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 down 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 run-

ning.

Storage Before you store the air compressor, make sure you do

the following:

1. Review the "Maintenance" and "Operating Proce- dures" sections and perform maintenance as nec- essary.

2. Be sure to drain water from the air tank.

3. Protect theelectrical cord and air hosefrom damage (such as being stepped on or run over). Wind them loosely around the compressor handle.

Store the air compressor in a clean and dry location.
