After any reversing operations, return lever to forward position. Operation DRILLING 1. Always unplug the drill when attaching or changing bits or accessories. 2. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use high speed steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped bits. 3. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to prevent damage to the material. 4. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting, but do not push hard enough to stall the motor or deflect the bit. 5. Hold tool firmly to control the twisting action of the drill. 6. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL—THIS CAN DAMAGE THE DRILL. 7. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. 9. With variable speed drills there is no need to center punch the point to be drilled. Use a slow speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep enough to drill without the bit skipping out. Drilling in Metal Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry. The cutting lubricants that work best are sulfurized cutting oil or lard oil; bacon-grease will also serve the purpose. Drilling in Wood 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. For larger holes, use power drill wood bits. Work that is apt to splinter should be backed up with a block of wood. Drilling in Masonry Use carbide tipped masonry bits at low speeds. Keep even force on the drill but not so much that you crack the brittle materials. A smooth, even flow of dust indicates the proper drilling rate. Bubble Level Your drill is equipped with a bubble level that assists you in drilling level holes. For horizontal drilling, tilt the drill up or down as required so that the bubble floats in the center of the parallel lines drawn on the glass. When the bubble is centered between the lines, as shown in Figure 3A, the drill is level. For vertical drilling, align the drill so that the bubble floats in the center of the bull’s-eye, as shown in Figure 3B. To assure accuracy, first place a level on your work piece and position it so that it is level. Then, when the drill reads level, the two will be aligned. (Any bubble level can only indicate level to the earth’s surface). NOTE: The level is filled with mineral oil that may cause minor skin irritation when contacted. If the level breaks and this fluid gets on your skin, rinse thoroughly with water. If any liquid gets in your eyes, rinse thoroughly with water and call a physician immediately. Keyless Chuck (DW106) Your tool features a keyless chuck for greater convenience. To insert a drill bit or other accessory, follow the steps listed below. 1. Unplug the drill. 2. Grasp the rear half of the chuck with one hand and use your other hand to rotate the front half counterclockwise, as shown in Figure 4. Rotate far enough so that the chuck opens sufficiently to accept the desired accessory. 3. Insert the bit or other accessory about 3/4" into the chuck and tighten securely by holding the rear half of the chuck and rotating the front portion in the clockwise direction. To release the accessory, repeat step 2 listed above. WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Keyless Chuck Removal Tighten the chuck around the shorter end of a hex key (not supplied) of 1/4" or greater size. Using a soft hammer or piece of wood, strike the longer end in the counterclockwise direction, as shown in Figure 5. This will loosen the chuck so that it can be unscrewed by hand. Chuck Installation Screw the chuck on by hand as far as it will go. Tighten the chuck around the shorter end of a 1/4" or larger hex key (not supplied) strike the longer end in the clockwise direction with a soft hammer, as shown in Figure 6. Keyed Chuck (DW100,DW101) Open chuck jaws by turning collar with fingers and insert shank of bit about 3/4" into chuck. Tighten chuck collar by hand. Place chuck key in each of the three holes, and tighten in clockwise direction. It’s important to tighten chuck with all three holes. To release bit, turn chuck counter clockwise in just one hole, then loosen the chuc...
