Do not modify this tool and do not use this tool for a purpose for which it was not intended. 11. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure. In addition, people with pacemakers should: • Avoid operating alone. • Do not use with power switch locked on. • Properly maintain and inspect to avoid electrical shock. • Any power cord must be properly grounded. Ground Fault Circuit Interrupter (GFCI) should also be implemented – it prevents sustained electrical shock. 12. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Do not use tool if plug is damaged. 13. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. 14. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. 15. Do not abuse the cord. Never use the cord for carry- ing, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. Do not use tool if cord is damaged. 16. When operating a power tool outdoors, use only a 3-wire grounded cord with a wire size of 14 gauge or larger. We recommend they be listed by Underwriters Laboratories (UL) in the USA or (CSA) Canadian Standards Association in Canada and be suitable for outdoor use. Cords marked for outdoor use are also suitable for indoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. 17. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock. 18. Use power tool ONLY on adequately rated circuits to avoid overheating of electrical systems. 19. Prevent accidental starting. Ensure switch is in the “OFF” position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch “ON” invites accidents. 20. Never let the power tool operate while unattended and unplug when not in use or before servicing. 21. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. 22. Never use this tool without the proper guard. The grinding wheel could shatter during use. Make sure the guard covers the side of the wheel facing you. 23. Never bounce the tool while grinding. This may crack the wheel. 24. Grinding metal will cause sparks! Keep them di- rected away from people and flammable materials. Always keep the guard positioned so that as much of the exposed disc as possible is pointing away from you. 25. Keep children and pregnant women away from the work area until the grinding is completed and the area has been cleaned up. 26. Always wear full eye, face and body protection. Wire bristles may break off and fly toward the user. Always wear ear protection when grinding in enclosed spaces. Noise level may be amplified in such locations and may cause permanent hearing loss. 27. Always wear an OSHA approved dusk mask or respirator when inside the work area. Replace the filter daily. NOTE: Not all dust masks offer protec- tion from lead paint dust. Be sure to use the proper mask for the job. 28. Before connecting the tool to the power supply fol- low the safety instructions for installing the grinding or cutting wheels. Do not lock the wheels too tight or cracks may occur. 29. Only use grinding or cutting wheels with the correct bore size for the spindle of the grinder. 30. Use standard parts. Do not use coolant or water and do not use as a fixed grinder. 31. Do not start the tool when the grinding or cutting wheels are touching the work area. 32. Keep the power cord well away from the cutting area during use. Always position the cord so that

it will not be caught in the workpiece when the grinder is in use. 33. Always have the guards in place and properly positioned when using grinding wheels or wire cup brushes. 34. Secure the material being grinded. Never hold it in your hand or across your legs. Do not use your legs or feet to stabilize the workpiece. Unstable support can cause loss of control and could result in lacera- tions or injury. 35. Use clamps or other practical ways to secure and support the workpiece to a stable platform. 36. Always make sure no one, including the user, is in line with the tool when starting the motor. 37. Always use both hands when operating the Angle Grinder. 38. Always hold this tool by the insulated gripping surfaces. If this tool should accidentally cut across its own cord or hidden wiring, all exposed metal parts will become live and could seriously shock the user. 39. When using the Angle Grinder, always maintain a firm grip on the tool. Keep your hands well away from the grinding wheel or brush. Never reach underneath the Angle Grinder while the sanding disk is in motion. 40. When the Angle Grinder is in operation, keep hands away from the cutting or grinding area. 41. Do not run the Angle Grinder while carrying it at your side. A moving grinding wheel or brush could cause lacerations or personal injury. 42. The disc will not stop immediately when the Angle Grinder is turned off. Exercise caution. 43. Do not set the Angle Grinder down after use until the grinding or cutting wheels have come to a complete stop. 44. Keep the handle of the Angle Grinder dry, clean and free from oil and grease. 45. Only use grinding and cutting wheels that are approved for a maximum speed of 11,000 RPM or greater. 46. After replacing a wheel or brush, always let the tool run for one minute in a well-protected area. If the new accessory has an undetected flaw, it should break apart in less than a minute. 47. Unplug Angle Grinder from power supply and place the switch in the locked or “OFF” position before making any assembly adjustments, changing ac- cessories or performing any inspection, mainte- nance or cleaning procedures. Such preventive safety measures reduce the risk of starting the tool accidentally. Such preventive safety measures reduce the risk of starting the tool accidentally which could cause serious personal injury. 48. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. Many accidents are caused by poorly maintained tools. 49. Maintain labels and nameplates on the Angle Grinder. These carry important information. If unreadable or missing, contact Performance Tool® for a replacement. 50. Do not disassemble the angle grinder. 51. Have your power tool serviced by a qualified repair person using only identical replacement parts This will ensure that the safety of the power tool is maintained. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of shock or injury. WARNING: Some dust created by power sanding contains chemicals known to the State of California to cause cancer, birth defects or other reproduc- tive harm. An example of this type of chemical is lead from lead based paints, Crystalline Silica from bricks and cement or other masonry, 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 expo- sure: work in a well ventilated area and work with approved safety equipment, such as dusk masks that are specially designed to filter out microscopic particles. WARNING: This product and its packaging contain a chemical known to the State of California to cause cancer, birth defects, or other reproductive harm.

ed by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool. Always attach grounded (3-prong) exten- sion cords to grounded (3-hole) outlets. If you must use an extension cord, be sure that the gauge is large enough to carry the amount of current necessary for your power tool. If not, your tool may experience a loss of power, excessive voltage drop or overheating. The smaller the gauge number, the heavier the cord (see table on next page). EXTENSION CORDS 1. Tools marked with “Grounding Required” have a three wire cord and three prong ground- ing plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock. (See Figure A.) 2. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically “live” terminal. (See Figure A.) 3. Your tool must be plugged into an ap- propriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the following illustration. (See Figure A) DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS GROUNDING GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS Figure A 1. 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.) 2. Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.) 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. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.
