GENERAL SAFETY RULES IMPORTANT SAFETY INSTRUCTIONS WARNING! READ AND UNDERSTAND ALL INSTRUCTIONS Failure to follow all instructions listed in the following pages may result in electric shock, fire, and/or serious injury. SAVE THESE INSTRUCTIONS SKU 93621 For technical questions, please call 1-800-444-3353 PAGE 2 WORK AREA 1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. 2. Do not operate pneumatic tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Pneumatic tools create sparks which may ignite flammables. 3. Keep bystanders, children, and visitors away while operating a pneumatic tool. Distractions can cause you to lose control. Protect others in the work area from debris such as metal filings and sparks. Provide barriers or shields as needed. PERSONAL SAFETY 1. Stay alert. Watch what you are doing, and use common sense when operating a pneumatic tool. Do not use a pneumatic tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating pneumatic 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. Avoid accidental starting. Be sure the Trigger (3) is off before connecting to the air supply. Carrying pneumatic tools with your finger on the Trigger, or connecting pneumatic tools to the air supply with the Trigger on, invites accidents. 4. Remove adjusting keys or wrenches before turning on the tool. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury. 5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations. 6. Use safety equipment. Always wear ANSI approved safety glasses underneath a full face shield, and hearing protection. TOOL USE AND CARE 1. Use clamps or other practical ways to secure and support the workpiece to a stable platform. Holding the work by hand is unstable and may lead to loss of control. Only work on a workpiece that is properly secured. SKU 93621 For technical questions, please call 1-800-444-3353 PAGE 3 2. Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. 3. Do not use the power tool if the Trigger does not turn it on or off. Any tool that cannot be controlled with the Trigger is dangerous and must be replaced. 4. Disconnect the air hose from the tool before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally. 5. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users. 6. Maintain tools with care. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired. 7. Check for misalignment or binding of moving parts, breakage of parts, damaged air hose (not included), 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. 8. 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. Service or maintenance performed by unqualified personnel could result in a risk of injury. 2. When servicing a tool, 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 injury. SPECIFIC SAFETY RULES 1. Maintain labels and nameplates on the Die Grinder. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. 2. To avoid accidental injury, always wear ANSI approved safety glasses, a full face shield, and hearing protection when operating the Die Grinder. SKU 93621 For technical questions, please call 1-800-444-3353 PAGE 4 3. Use clean, dry, regulated, compressed air at 90 PSI. Do not exceed the recommended 90 PSI. Never use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool. 4. When connecting to the air supply: Prior to each use, if an automatic oiler is not used, add two drops of air tool oil (not included) into the Air Inlet (20) fitting of the Die Grinder. 5. Always disconnect the Die Grinder from its compressed air supply source, and squeeze the Trigger (3) to release all compressed air in the tool before performing any maintenance or services. 6. Industrial applications must follow OSHA requirements. 7. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement or other masonry products, arsenic and chromium from chemically treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety Code 25249.5, et seq.) 8. WARNING! The warnings, precautions, and instructions discussed in this manual cannot cover all possible conditions and situations that may occur. The operator must understand that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.
