2.Do not operate compressors in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Compressors create sparks which may ignite the dust or fumes.
3.Keep bystanders, children, and visitors away while operating a compressor.
Provide barriers or shields as needed.
ELECTRICAL SAFETY
1.Grounded compressors must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the compressors should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
2.Do not expose compressors to rain or wet conditions. Water entering an electric motor will increase the risk of electric shock.
3.Do not abuse the Power Cord. Never use the Power Cord to pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving parts. Replace damaged Power Cords immediately. Damaged Power Cords increase the risk of electric shock.
4.An extension cord must never be used with this item. Connecting this item to an outlet through an extension cord may cause electrical damage to the motor and could present a fire hazard.
PERSONAL SAFETY
1.Stay alert. Watch what you are doing, and use common sense during use. Do not use while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating may result in serious personal injury.
2.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.
3.Avoid accidental starting. Be sure the Power Switch is turned off before plugging in. Plugging in compressors with the Power Switch on, invites accidents.
4.Remove adjusting keys or wrenches before turning the compressor on. A wrench or a key that is left attached to a rotating part of the compressor may result in personal injury.
5.Do not overreach. Keep proper footing and balance at all times.

6.Use safety equipment. Always wear eye protection. Make sure you are wearing your protective clothing, safety glasses with side shields and dust mask or air respirator, if appropriate.
TOOL USE AND CARE
1.Do not force the compressor. Use the correct compressor for your application.
The correct compressor will do the job better and safer at the rate for which it is designed. Never attempt to force the compressor to provide more pressure than it was designed for.
2.Do not use the compressor if the Power Switch does not turn it on or turn it off. Any compressor that cannot be controlled with the Power Switch is dangerous and must be repaired or replaced.
3.Disconnect the Power Cord Plug from the power source before making any adjustments, changing accessories, or storing the compressor. Such preventive safety measures reduce the risk of starting the compressor accidentally.
4.Keep idle compressors out of reach of children and other untrained persons.
Compressors are dangerous in the hands of untrained users.
5.Maintain compressors with care. Keep all components of this product clean and dry. Do not use a damaged compressor. Tag damaged compressors “Do not use” until repaired.
6.Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the compressor’s operation. If damaged, have the compressor serviced before using. Many accidents are caused by poorly maintained compressors.
7.Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one compressor may become hazardous when used on another compressor.
SERVICE
1.Compressor service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel could result in a risk of injury.
2.When servicing a compressor, use only identical replacement parts. Follow instructions in the “Inspection, Maintenance, And Cleaning” section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES
1.CAUTION! Prior to its first use, and thereafter prior to each subsequent use, make sure to fill the Air Compressor with a premium quality, 30 weight, nondetergent oil to the specified level. Running the Air Compressor with no oil or with low oil will cause damage to the equipment and void its warranty. Refer to the “Operating Instructions” section for details on filling the Air Compressor with oil.
2.When filling the Air Compressor with oil, make sure to unscrew (do not pull) the Oil Fill Cap to remove.
3.Use eye and ear protection. Always wear ANSI-approved safety impact eye goggles, and ear plugs when using the Air Compressor.
4.Make sure all tools and equipment used with the Air Compressor are rated to the appropriate air pressure capacity of the Air Compressor. Do not use any tool or equipment that does not operate from 0-115 PSI. If necessary, check the owner’s manual of the tool or equipment for its air pressure rating.
5.Always disconnect the Air Compressor from its electrical outlet, release any remaining air pressure from the unit, and disconnect all pneumatic tools and equipment from the unit, before performing any services or maintenance.
6.Avoid injury. Never direct the air jet at people or animals.
7.Inspect safety valve daily. If the safety valve is not working properly, tank pressure can build up to dangerous levels. The tank could explode. For this reason, pull the ring on the safety valve before each use and verify that it operates freely. Replace safety valve if it does not operate freely.
Never remove or alter the factory sealed Safety Release Valve.
8.Do not attempt to readjust the automatic start and shutoff valves. Any change to the automatic ON/OFF pressure levels will cause additional stress on the motor, which may result in shortened motor life.
9.Drain the Air Compressor’s air tank every day. Do not allow moisture to build up inside the Air Tank.
10.Do not unscrew the tank drain valve so that more than four threads are showing.
11.Avoid risk of tank explosion.
a)Avoid weakening of tank by draining condensation after each use.
b)Never modify tank by drilling holes, welding to it, or modifying it’s parts.
c)The tank is designed, and factory set, to operate within a specific pressure range. For that reason, never make adjustments to, or substitute parts, to the compressor.
12.Avoid bodily injury from moving parts. The compressor cycles on automatically, without notice. For this reason, always keep hands and arms away from compressor
