GLOSSARY

• CFM: Cubic feet per minute.
• SCFM: Standard cubic feet per minute; a unit of measure 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: Samples of compressor outfits, taken from production, were submitted to U.L. and found to comply with their requirements for design and performance.
• 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 re-start automatically. The low pressure at which the motor automatically re-starts is called “cut-in pressure”.
• Cut-Out Pressures: When you turn on your air compressor and it begins to run, air pressure in the 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 pressure at which the motor shuts off is called “cut-out pressure”.

GENERAL INFORMATION

• You have purchased an air compressor unit consisting of a 1-cylinder, single-stage air compressor pump, an air tank, air hose, wheels, handle, and associated controls.
• You will also find an air chuck.
• 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, airbrushes, sandblasters, or inflating tires and plastic toys, spraying weed killers, insecticides, etc.
• Separate air transformers that combine the functions of air regulation and/or moisture and dirt removal should be used where applicable.

DESCRIPTION OF OPERATION

• Air Compressor Pump: To compress air, the piston moves up and down in the cylinder. On the downstroke, air is drawn in through the air intake valves. The exhaust valve remains closed. On the upstroke of the piston, the air is compressed. The intake valves close and compressed air is forced out through the exhaust valve, 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 what is 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.
• Pressure Release Valve: 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 try to start but will be unable to. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from the valve for a few seconds. No air should be heard 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.
• Safety Valve: If the pressure switch does not shut off the air compressor at its cut-out pressure setting, the safety valve will protect against high pressure by “popping out” at its pre-set pressure.
• Regulator: The air pressure coming from the air tank is controlled by the regulator knob. Turn the knob clockwise to increase pressure and counter-clockwise to decrease pressure. To avoid minor readjustment after making a change in the 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 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 regulator and is always less or equal to the tank pressure. See “Operating Procedures.”
• Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank.

ASSEMBLY INSTRUCTIONS

Tools Needed for Assembly

• pipe thread sealant (not included)
• an adjustable wrench for attaching the pressure regulator
• a %6″ socket or open-end wrench for attaching the wheels and hose adapter.
• a 76″ open-end wrench for attaching the air pressure gauges
• a ⅗” hex key for installing the plug in the regulator
• a ⅜” open-end wrench to tighten handle screws
• a #2 Phillips screwdriver for attaching the control cover.

Installing Wheels, Handle, Rubber Foot Strip

WARNING: THE WHEELS AND HANDLE DO NOT PROVIDE ADEQUATE CLEARANCE, STABILITY OR SUPPORT FOR PULLING THE UNIT UP AND DOWN STAIRS OR STEPS. THE UNIT MUST BE LIFTED OR PUSHED UP A RAMP.

1. Attach the handle to the inside of the compressor sad- die by pushing the handle in, until the slot in the handle engages with the tabs in the saddle. Pull the handle back and install the two screws, one on each side of the saddle. Tighten securely.
   CAUTION: It may be necessary to brace or support one end of the outfit when attaching the wheels and the rubber foot strip because the air compressor will tend to tip.

2. Remove the protective paper strip from the adhesive-backed rubber foot strip. Attach the rubber foot strip to the bottom of the air tank leg. Press firmly into place.

3. Attach one wheel to each side of the air compressor. Use one shoulder bolt and one nut for each wheel. Tighten securely.

Installing Regulator

• Use a small amount of pipe thread sealant on all pipe thread joints.
• Install the regulator on the end of the manifold using the short pipe nipple. The arrow on the bottom of the regulator must point away from the manifold for the regulator to function properly.
• Install the adapter and plug in the regulator. The plug is supplied with the regulator. Install the rear cover and the gauges at the same time. See the diagram below.

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 the 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. If humidity is high a Sears air filter can be installed to remove excessive moisture. Follow the instructions packaged with the air filter for proper installation.

Lubrication and Oil
This unit needs no additional lubrication or oiling.

Extension Cords: Use an extra air hose instead of an extension cord to avoid voltage drop and power loss to the motor.

If an extension cord must be used, be sure it is:

• 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.
• 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.)

Grounding Instructions

WARNING
IMPROPER GROUNDING CAN RESULT IN 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.

1. The 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 by all local codes and ordinances. The outlet must have the same configuration as the plug. DO NOT USE AN ADAPTER.
2. 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.
3. Inspect the plug and cord before each use. Do not use if there are signs of damage.

DANGER
RISK OF ELECTRICAL SHOCK. IF REPAIRING OR REPLACING 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 IS GREEN – WITH OR WITHOUT YEL- LOW STRIPES.)

If these grounding instructions are not completely understood, or if in doubt as to whether the compressor is properly grounded, have the installation checked by a qualified electrician.

Break-In Procedures

This procedure is only required the first time the air compressor is put into service.

1. Set the pressure switch OFF/AUTO lever to the “OFF” position.
2. Plug the power cord into the correct branch circuit receptacle.
3. Turn the regulator clockwise, opening it fully, to prevent air pressure build-up in the tank.
4. Move the OFF/AUTO lever to “AUTO”. The compressor will start.
5. Run the compressor for 15 minutes. Make sure the regulator is open and there is no 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 then the motor will stop.

OPERATING PROCEDURES

1. Before attaching the air hose or accessories, make sure the OFF/AUTO lever is set to “OFF” and the air regulator is closed. (Close it by turning it counter-clockwise.)

2. Attach hose and accessories.
   WARNING: TOO MUCH AIR PRESSURE CREATES A HAZARDOUS RISK OF BURSTING. CARE- FULLY FOLLOW STEPS 3 AND 5 EACH TIME THE COMPRESSOR IS USED.
   CAUTION: COMPRESSED AIR FROM THE OUTFIT 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.

3. Check the manufacturer’s maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating.

4. Turn the OFF/AUTO lever to “AUTO” and allow tank pressure to build. The motor will stop when tank pressure 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-ventilated areas; free of gasoline or other solvent vapors. Do not operate the compressor near the spray area.

   • When you are finished:

7. Set the “OFF-AUTO” lever to “OFF”.

8. Turn the regulator counter-clockwise and set the outlet pressure to zero.

9. Remove the air tool or accessory.

10. Open the regulator and allow the air to slowly bleed from the tank. Close the regulator when tank pressure is approximately 20 psi.

11. Drain water from the air tank.
    WARNING: WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, WATER WILL CORRODE AND WEAKEN THE AIR TANK CAUSING A RISK OF AIR TANK RUPTURE.
    With tank pressure at approximately 20 psi., open the drain cock and allow moisture to drain.
    NOTE: If the drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.

12. After the water has been drained, close the drain cock. The air compressor can now be stored

MAINTENANCE

WARNING: 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 PERFORMING ANY MAINTENANCE OR REPAIR, UNPLUG THE COMPRESSOR AND BLEED OFF ALL AIR PRESSURE.

Motor
The motor has an automatic reset thermal overload protector. If the motor overheats for any reason, the love load protector will shut off the motor. The motor must t allowed to cool down before restarting. The compress will automatically restart after the motor cools.
If the overload protector shuts the motor off frequently check for a possible voltage problem. Low voltage ca 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 ar remain dim when the motor is started and is running.

STORAGE

Before you store the air compressor, make sure you do the following:

1. Review the “Maintenance” section on the preceding pages and perform maintenance as necessary. Be sure to drain water from the air tank.
2. Protect the electrical cord and air hose from 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.
