Allow the bit to strike the bottom of the chuck. Center the bit in the chuck jaws and tighten the jaws by hand to align the bit. 3. Place the chuck key into each of the three holes in the chuck, turning it clockwise to tighten the chuck securely. NOTE: Never use a wrench or means other than a chuck key to tighten or loosen the chuck. 4. To remove the bit, unplug the tool, insert the chuck key into one of the holes in the chuck and turn it counterclockwise. Be sure that the shank of the bit and the chuck jaws are clean. Dirt particles may cause the bit to line up improperly. Do not use bits larger than the maximum recommended capacity of the drill because gear damage or motor overloading may result. For best performance, be sure that the bits are properly sharpened before use. To prevent personal injury, always remove the chuck key from the chuck after each use. ADJUSTING THE SIDE HANDLE To reduce the risk of injury, always use a side handle when using this tool. Always brace or hold securely. 1. Unplug the tool. 2. Loosen the side handle by unscrewing the side handle grip until the side handle rotates freely. 3. Rotate the side handle to the desired position. 4. Tighten the side handle grip securely. DEPTH ROD To adjust the depth rod, loosen the handle and move rod so that the distance between the end of the rod and the end of the bit equals the desired drilling depth. When drilling with depth rod, stop when end of rod reaches surface of material. Pre-Operation SETTINGS Hammer drills have two settings: drilling and hammer-drilling. 1. For drilling, turn the hammer/drill lever towards the drill symbol. 2. For hammer-drilling, turn the hammer/drill lever towards the hammer symbol . NOTE: To engage the hammering mechanism, maintain pressure on the bit. When pressure on the bit is released, the hammering action will stop. USING FORWARD/REVERSE The forward/reverse lever can only be adjusted when the trigger is not pressed. Always allow the motor to come to a complete stop before using the forward/reverse lever. 1. For forward (clockwise) rotation, push the forward/reverse lever to the left (when viewed from the back of the tool). 2. For reverse (counterclockwise) rotation, push the forward/reverse lever to the right (when viewed from the back of the tool). Allow the motor to come to a full stop before reversing. NOTE: When hammer-drilling, use the tool in forward rotation (clockwise) only. NOTE: The hammer/drill lever must be in either drill, or hammer-drill mode at all times. There are no operable positions between the two. Operation Safety glasses and ear protection must be worn during operation. Make sure work is held securely in vise or clamped in place prior to starting operation. Loose work may spin and cause bodily injury. HAMMER-DRILLING OPERATION Always unplug the drill when attaching or changing bits or accessories. There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury. When drilling in concrete, granite, tile, etc., move the hammer/drill lever to the hammer-drill setting. Be sure to use a tungsten-carbide tipped bit. Use sharp drill bits only. Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. DRILLING OPERATION Always unplug the drill when attaching or changing bits or accessories. Use sharp drill bits only. When drilling in 4 DG190600CK and DG190625DI Operation (Cont’d.) wood, metal or plastic materials, move the hammer/drill lever to the drill position. DRILLING IN WOOD For WOOD, use the low speed setting and use twist drill bits, spade bits, power auger bits, or hole saws. USE ONLY in the “low speed” gear range. Start drilling with slow speed and increase to full power while applying firm pressure on the tool. Holes in wood can be made with the same twist drills used for metal. These bits may overheat unless pulled out frequently to clear chips from the flutes. Work that is apt to splinter should be backed up with a block of wood. When drilling in wood, composition materials and plastic, start the drill slowly, gradually increasing speed as you drill. Use low speeds for plastics with a low melting point. When drilling in wood, the best results are obtained with wood drills equipped wit...
