g ) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust‑related hazards. h ) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second. 4) Power Tool Use and Care a ) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. b ) 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. c ) Disconnect the plug from the power source and/ or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. d ) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. e ) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition 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. Additional Safety Instructions for Demolition Hammers • Wear ear protectors. Exposure to noise can cause hearing loss. English • Use auxiliary handles 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 or its own cord. 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 operated on does not conceal electric or gas service and that their locations have been verified with the utility companies. • 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. Tighten the side handle securely before use. • Do not recondition accessories yourself. Chisel reconditioning should be done by a qualified specialist. Improperly reconditioned accessories 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. • Ensure the chisel is secured in place before operating the tool. • In cold‑weather conditions or when the tool has not been used for a longer period of time, let the tool run with no load for several minutes before use. • When working above ground level ensure the area below is clear. • Do not touch the chisel or the parts close to the chisel immediately after operation, as they may be extremely hot and cause burns to the skin. • Always direct the power cable to the rear, away from the chisel. • 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. 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 cutting operation is dusty. 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. 5
