GENERAL SAFETY INSTRUCTIONS
WARNING
Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. The floor must not be slippery from wax or dust.
Do not operate power tools in explosive atmo-spheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating tools. Distractions can cause you to lose control.
Operate the air compressor in an open area at least 18 in. away from any wall or object that could restrict the flow of fresh air to ventilation openings.
ELECTRICAL SAFETY
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.
Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tool or pull the plug from an outlet. Keep the cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.
PERSONAL SAFETY
Eye protection which conforms to ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when loading, operating, or servicing this tool. Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.
WARNING
The brass components of this product contain lead, a chemical known to the state of California to cause birth defects (or other reproductive harm).
(California health & safety code § 25249.5, et seq.)
The employer and/or user must ensure that proper eye protection is worn. We recommend a Wide Vision Safety Mask for use over eyeglasses or standard safety glasses that provide protection against flying particles both from the front and side. Always use eye protection which is marked to comply with ANSI Z87.1.
Additional safety protection will be required in some environments. For example, the working area may include exposure to a noise level which can lead to hearing damage. The employer and user must ensure that any necessary hearing protection is provided and used by the operator and others in the work area. Some environments will require
the use of head protection equipment. When required, the employer and user must ensure that head protection marked to comply with ANSI Z89.1 is used.
Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tools while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection. A dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the tool in unexpected situations.
TOOL USE AND CARE
Do not exceed the pressure rating of any component in the system.
Protect material lines and air lines from damage or puncture. Keep the hose and power cord away from sharp objects, chemical spills, oil, solvents, and wet floors.
3
Check hoses for weak or worn condition before each use, making certain all connections are secure. Do not use if a defect is found. Purchase a new hose or take to a qualified service center for examination and repair.
Release the pressure within the system slowly. Dust and debris may be harmful.
Store idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
Maintain tools with care. Follow maintenance instructions. Properly maintained tools are easier to control.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
Never point any tool toward yourself or others.
Keep the exterior of the air compressor dry, clean, and free from oil and grease. Always use a clean cloth when
cleaning. Never use brake fluids, gasoline, petroleum-based products, or any strong solvents to clean the unit. Following this rule will reduce the risk of deterioration of the enclosure plastic.
SERVICE
Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.
Disconnect the power supply, open the drain valve to decompress the tank and allow water to drain, and allow the air compressor to become cool to the touch before servicing. Turn the pressure regulator knob fully counter clockwise after shutting off the compressor.

ELECTRICAL SAFETY
EXTENSION CORDS
NOTE: Avoid use of extension cords.
1.For optimum performance, plug the compressor power cord directly into a grounded wall socket. Do not use an extension cord unless absolutely necessary. Instead, use a longer air hose to reach the area where the air is needed.
2.If use of an extension cord cannot be avoided, the cord should be no longer than 50 feet and be a minimum wire size of 12 gauge (AWG). Do not use a 16 or 14 gauge extension cord.
3.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 your extension cord is in good condition. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The smaller the gauge number, the heavier the cord.
4.When working with the air compressor outdoors, use an extension cord that is designed for outside use. This is indicated by the letters “WA” on the cord’s jacket.
5.Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation.
WARNING Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so can result in serious personal injury.
WARNING Check the extension cords before each use. If damaged, replace immediately. Never use the air compressor with a damaged cord since touching the damaged area could cause electrical shock resulting in serious personal injury.
NOTE: Use longer air hoses instead of long extension cords. Your air compressor will run better and last longer.
ELECTRICAL CONNECTION
1.This air compressor is powered by a precision built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only (normal household current).
2.Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the air compressor does not operate when plugged into an outlet, double check the power supply.
into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
2.Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.
3.The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding conductor to a live terminal.
4.Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.
5.Replace a damaged or worn cord immediately.
WARNING Improper connection of the equipmentgrounding conductor can result in a risk of electric shock.
6.This air compressor is intended for use on a circuit that has an outlet like the one shown in the figure 1. It also has a grounding pin like the one shown. This product must be grounded.
Fig. 1
Grounding pin
120V Grounded outlet
7. Never use an electrical adapter with this grounded plug.
SPEED AND WIRING
1.The no-load speed of the electric motor varies by model and specification. The motor speed is not constant and decreases under a load or with lower voltage. For voltage, the wiring in a shop is as important as the motor’s horsepower rating.
2.A line intended only for lights cannot properly carry a power tool motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to support two or three tools.
GROUNDING INSTRUCTIONS
1.In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This air compressor is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged

KNOW YOUR AIR COMPRESSOR (see figure 2)
Before attempting to use this product, familiarize yourself with all operating features and safety rules.
Oil-free universal motor
Your air compressor features permanently lubricated bearings.
Air compressor pump
To compress air, the piston moves up and down in the cylinder. On the down stroke, air is drawn in through the air intake valve while the exhaust valve remains closed. On the upstroke, air is compressed, the intake valve closes and compressed air is forced out through the exhaust valve, into the discharge line, through the check valve and into the air tank.
On/Off power switch
This switch is used to start or stop the air compressor. Moving the switch to the (ON) position will provide automatic power to the pressure switch which will allow the motor to start when the air tank pressure is below the factory set cut-in pressure. When in the (ON) position, the pressure switch stops the motor when the
