Use of the power tool for operations different from those intended could result in a hazardous situation. Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. Empty dust container frequently, especially when sanding wood with polyurethane, varnish, shellac or similarly coated surface. Fine particles of sanding dust may self ignite and cause fire. Service 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. Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts. SAVE THESE INSTRUCTIONS Rotary Hammer Safety Rules Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or it own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite. Wear ear protectors when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss. Use a metal detector to determine if there are gas or water pipes hidden in the work area or call the local utility company for assistance before beginning the operation. Striking or cutting into a gas line will result in explosion. Water entering an electrical device may cause electrocution. -3 Always use the side handle for maximum control over torque reaction or kick-back. Never attempt to operate this tool with one hand. The slip clutch engages if you firmly control the tool during a torque reaction or kickback. Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust. Safety goggles or eye protection will help deflect fragments of the material that may be thrown toward your face and eyes. Dust generated or gases released from the material you are cutting (i.e. asbestos insulated pipes, radon) may cause respiratory difficulties. Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by hammer-drill action may be harmful to your hands and arms. Position the cord clear of rotating bit. Do not wrap the cord around your arm or wrist. If cord becomes entangled with the spinning bit it could entrap you causing serious personal injury. Position yourself to avoid being caught between the tool or side handle and walls or posts. Should the bit become bound or jammed in the work, the reaction torque of the tool could crush your hand or leg. Do not strike the bit with a handheld hammer or sledge hammer when attempting to dislodge a bound or jammed bit. Fragments of metal from the bit could dislodge and strike you or bystanders. Never place the tool down until the bit or accessory have come to a complete stop. Do not use dull or damaged bits and accessories. Dull or damaged bits have a greater tendency to bind in the workpiece. When removing the bit from the tool avoid contact with skin and use proper protective gloves when grasping the bit or accessory. Accessories may be hot after prolonged use. Do not run the tool while carrying it at your side. The spinning drill bit may become entangled with clothing and injury may result. !WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known 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 and other masonry products, and • 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. -4 Symbols IMPORTANT: Some of the following symbols may be used on your tool.
