that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f ) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g ) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. h ) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations. 5) Service a ) 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. Specific Safety Rules for Rotary Hammers • Wear ear protectors. Exposure to noise can cause hearing loss. • Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury. • Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. • Be certain that the material being drilled/ demolished does not conceal electric or gas service and that their locations have been verified with the utility companies. • 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. • Wear safety goggles or other eye protection. Hammering operations cause chips to fly. Flying particles can cause permanent eye damage. Wear a dust mask or respirator for applications that generate dust. Ear protection may be required for most applications. • Keep a firm grip on the tool at all times. Do not attempt to operate this tool without holding it with both hands. Operating this tool with one hand will result in loss of control. Breaking through or encountering hard materials such as re-bar may be hazardous as well. Additional Safety Rules for Rotary Hammers • Do not operate this tool for long periods of time. Vibration caused by hammer action may be harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure by taking frequent rest periods. English • Do not recondition bits yourself. Chisel reconditioning should be done by an authorized specialist. Improperly reconditioned chisels could cause injury. • Accessories and tool may get hot during operation. Wear gloves when handling them if performing heat producing applications such as hammerdrilling and drilling metals. • Never lay the tool down until the bit has come to a complete stop. Moving bits could cause injury. • Do not strike jammed bits with a hammer to dislodge them. Fragments of metal or material chips could dislodge and cause injury. • Slightly worn chisels can be resharpened by grinding. • Do not overheat the bit (discoloration) while grinding a new edge. Badly worn chisels require reforging. Do not reharden and temper the chisel. • Do not use this tool to mix or pump easily combustible or explosive fluids (benzine, alcohol, etc.). • Do not mix or stir inflammable liquids labelled accordingly. Additional Safety Information WARNING: Never modify the power tool or any part  of it. Damage or personal injury could result. WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if operation is dusty. ALL USERS AND BYSTANDERS MUST ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT: • ANSI Z87.1 eye protection (CAN/CSA Z94.3), • ANSI S12.6 (S3.19) hearing protection, • NIOSH/OSHA/MSHA respiratory protection. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains 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 and other masonry products, and • arsenic and chromium from chemicallytreated 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. • Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing 3
