English 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. Additional 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 tools by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the opeartor an electric shock. • 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. It is recommended that the side handle be used at all times. 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. Tighten the side handle securely before use. • The hammer is only for light chiselling applications. • The forward/reverse switch must be in the forward position when chiselling. • 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. • 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. • Do not recondition bits yourself. Slightly worn chisels can be resharpened by grinding. Chisel reconditioning should be done by an authorized specialist. Improperly reconditioned chisels could cause injury. • Wear gloves when operating tool or changing bits. Accessible metal parts on the tool and bits may get extremely hot during operation. Small bits of broken material may damage bare hands. • 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. • Keep the power cord away from the rotating bit. Do not wrap the cord around any part of your body. An electric cord wrapped around a spinning bit may cause personal injury and loss of control. • Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in moving parts. • An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge has more capacity than 18 gauge. An undersized cord 3
