PERSONAL SAFETY 1. Stay alert. Watch what you are doing, and use common sense when operating a power tool. Do not use a power tool 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. 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.
. 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. 6. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool. SERVICE 1. Tool service must be performed only by qualified repair personnel.
5. Avoid injury. Never direct compressed air at people or animals. 6. Make sure the Air Compressor is located on a flat, level, sturdy surface capable of supporting the weight of the Compressor and any additional tools and equipment. 7. Industrial applications must follow OSHA guidelines. 8. Never stand on the Air Compressor. Serious injury could result if the Compressor is tipped. 9. Never leave the Air Compressor unattended when it is plugged in and running.
GROUNDING WARNING! Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use.
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS 4. Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. (See Figure B.) 5. Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.
UNPACKING When unpacking, check to make sure all the parts shown on the Parts List on page 14 are included.

Always make sure the Pressure Switch (57) of the Air Compressor is in its “OFF” position and the unit is unplugged from its electrical outlet prior to performing any assembly on this unit. 2.
4. Pressure Regulator Knob (14): The Pressure Regulator Knob enables the operator to adjust output pressure to the pneumatic tool being used. To increase the amount of air pressure to the tool, turn the Pressure Regulator Knob clock wise. To decrease the amount of air pressure to the tool, turn the Pressure Regulator Knob counterclockwise. (See Figure D.) 5.
2. Before operating, make sure the Air Compressor is set up in a well ventilated area, on a flat, level, solid surface well away from any flammable objects. To Start The Compressor: 1. Check to make sure the Air Compressor’s water Drain Valve (4) is fully closed. (See Figure E.) FIGURE E DRAIN VALVE (4) 2. Connect one end of the air supply hose (not included) to the pneumatic tool being used. Then connect the other end of the hose to the Quick Coupler (11) on the Air Compressor. (See Figure D.) 3.
6. When finished using the Air Compressor, turn its Pressure Switch (57) to its “OFF” position. Then, unplug the unit from its electrical outlet. (See Figure D.) 7. Pull the ring on the Safety Valve (10) to release any remaining compressed air in the Air Tank (3) of the Compressor. (See Figure D.) 8. Squeeze the trigger of the pneumatic tool being used to release any remaining compressed air in the air hose and tool. Then disconnect the air hose from the tool and from the Air Compressor. 9.
4. To clean, wipe with a damp cloth, using a mild detergent. Never use solvents such as thinner, alcohol, trichloroethylene, etc. to clean the Air Compressor. 5. To replace the Motor Carbon Brushes: It may become necessary at sometime to replace or clean the two Carbon Brushes (68) when the Motor performance decreases, or stops working completely. The Carbon Brushes are located on each side of the Motor Cover (46). To replace the Carbon Brushes, remove the two Brush Holder Covers. Remove the Brush Caps.
TROUBLESHOOTING Problem Circuit breaker/fuse trip often. Overheating. Possible Solution 1. Do not use an extension cord. Link additional air hoses together to acquire additional length. 2. Restricted air passages. 2. Check all air passages for clogs. 3. Back pressure in pump head. 3. Have a qualified service technician replace check valve and/or pressure switch bleeder valve. 1. Relocate air compressor to an area with cool, dry, well circulated air. 1. Poor ventilation. Motor stalls. 2.
