Guidelines for Using Extension Cords • If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use. • Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it. • Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

Use only specificallyrecommended accessories. Others may be hazardous. Installing Bits into Keyed Chucks Fig. 1 Loosen Tighten 1. Open the chuck jaws wide enough to insert the bit. Be sure the bit shank and chuck jaws are clean. Dirt particles may prevent the bit from lining up properly. 2. When using drill bits, insert the bit into the chuck. Center the bit in the chuck jaws and lift it about 1/16" off of the bottom. Tighten the chuck jaws by hand to align the bit. When using screwdriver bits, insert the bit far enough for the chuck jaws to grip the bit shank. Tighten the chuck jaws by hand to align the bit. 3. Place the chuck key in each of the three holes in the chuck, turning it clockwise as shown. Tighten securely. 4. To remove the bit, insert the chuck key into one of the holes in the chuck and turn it counterclockwise. WARNING To prevent personal injury, always remove the chuck key from thechuck after each use. Using Forward/Reverse Switch WARNING To reduce the risk of injury, wear safety goggles or glasses with sideshields. Unplug the tool beforechanging accessories or makingadjustments. OPERATION Fig. 2 Reverse Forward 1. For forward (clockwise) rotation, slide the forward/reverse switch to the left. 2. For reverse (counterclockwise) rotation, slide the forward/reverse switch to the right. NOTE: To prevent damage to the motor, allow the tool to come to a complete stop before reversing. WARNING To reduce the risk of explosion,electric shock and property damage, always check the work areafor hidden electrical wires or pipeswhen drilling. Starting, Stopping and ControllingSpeed 1. To start the tool, pull the paddle switch. 2. To stop the tool, release the paddle switch. 3. To vary the driving speed, increase decrease pressure on The further the paddle the greater the speed. 6 WARNING To reduce the risk of explosion,electric shock and property damage, always check the work areafor hidden electrical wires or pipeswhen drilling. Drilling 1. Before drilling, be sure the workpiece is clamped securely. Use backing material to prevent damage to the workpiece during breakthrough. 2. When starting a hole, place the drill bit on the work surface and apply firm pressure. Begin drilling at a slow speed, gradually increasing the speed as you drill. 3. Use enough pressure on the tool to keep the bit drilling or driving constantly, but do not push hard enough to stall the bit. 4. Reduce pressure and ease the bit through the last part of the hole. While the tool is still running, pull the bit out of the hole to prevent jamming. Stalling If the tool seems as if it is about to stall, maintain a firm grip and reduce pressure slightly to allow the bit to regain speed. If the tool does stall, release the paddle switch immediately. Reverse the motor, remove the bit from the work and start again. Do not press the paddle switch on and off in an attempt to start a stalled drill. This can damage the drill. APPLICATIONS Selecting Bits When selecting a bit, use the right type for your job. For best performance, always use sharp bits. Drilling in Wood, Composition Materials and Plastic When drilling in wood, composition materials and plastic, start the drill slowly, gradually increasing speed as you drill. When using twist drill bits, pull the bit out of the hole frequently to clear chips from the bit flutes. Use low speeds for plastics with a low melting point. Drilling in Masonry When drilling in masonry, use high speed carbide-tipped bits. Drilling soft masonry materials such as cinder block requires little pressure. Hard materials like concrete require more pressure. A smooth, even flow of dust indicates the proper drilling rate. Do not let the bit spin in the hole without cutting. Do not use water to settle dust or to cool bit. Both actions will damage the carbide. Drilling in Metal When drilling in metal, use high speed steel twist dr...
