Accessories that may be suitable for one tool, may become hazardous when used on another tool. SERVICE • Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. • When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury. Additional Safety Instructions for Demolition Hammers • Hold tool by insulated gripping surfaces (side handle and rear handles) when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. • Wear ear protectors when hammering for extended periods of time. Prolonged exposure to high intensity noise can cause hearing loss. • 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. • 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 be hazardous as well. • 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. 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 hand. • Never place 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. NOTE: Do not overheat the bit (discoloration) while grinding a new edge. Badly worn chisels require reforging. Do not reharden and temper the chisel. 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 (CCA). 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 sawdust from treated lumber. Do not allow dust to get into your mouth, eyes or lay on the skin. Wear protective clothing whenever possible. • The label on your tool may include the following symbols. V................volts A ......................amperes Hz ..............hertz W ....................watts min ............minutes ....................alternating current ..........direct current no ....................no load speed ................Class II Construction ......................earthing terminal ..............safety alert symbol .../min ..............revolutions per minute Operation Your tool is powered by a DEWALT built motor. Be sure your power supply agrees with name plate marking. Voltage decreases of more than 10% will cause loss of power and overheating. All DEWALT tools are factory tested: if this tool does not operate, check the power supply. Switch (Fig. 1) The switch on your hammer is designed to lock-on. To turn the tool on, press the rear half of the rocker switch (A) upward. To stop the tool, press the forward half of the rocker switch. This demolition hammer has adjustable speed and impact control capability. Rotate the adjust ment dial (E) to the desired speed and impact force for the application. Low Speed -for chipping tile or breaking material that needs more control. High Speed -for breaking holes in concrete or brick. Tool may be used in low or high depending on users’ removal needs. Side Handle (Fig. 2) TO ADJUST THE SIDE HANDLE: 1. Loosen the side handle clamp knob (C). 2. Adjust the side handle assembly (D) to the desired position. 3. Lock the side handle in place by fully tightening the clamp knob. Bit Installation (Fig. 3) 1. Clean, then smear the bit shank with grease. 2. Fully insert the bit shank into the ch...
