The tool speed can be controlled from minimum to maximum nameplate rated RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1). "LOCK-ON" BUTTON Your tool is also equipped with a “Lock-ON” button located on the left side of the trigger handle that allows for operation at maximum RPM without holding the trigger (Fig. 1). TO LOCK TRIGGER "ON": squeeze trigger, depress button and release trigger. TO UNLOCK THE TRIGGER: squeeze trigger and release it without depressing the "Lock- ON" button. !WARNING If the “Lock-ON” button is continuously being depressed, the trigger can not be released. REVERSING SWITCH BUTTON The reversing switch button is located above the trigger switch and is used to reverse rotation of the bit. For forward rotation, (with the chuck pointed away from you) move button to the far left. For reverse rotation move the button to the far right. !CAUTION Do not change direction of rotation until the tool comes to a complete stop. Shifting during rotation of the chuck can cause damage to the tool. HIP CLIP Your tool is equipped with a hip clip that allows you to conveniently attach your drill to your belt, (Fig.1) This feature will allow you to have both hands free when climbing a ladder or positioning material to be fastened. CHUCK KEY & STORAGE AREA Keyed models are equipped with a chuck key that is conveniently located on the cord protector where it is always handy and unlikely to get lost or misplaced. INSERTING BIT For small bits, open jaws enough to insert the bit up to the flutes. For large bits, insert the bit as far as it will go. Center the bit as you close the jaws by hand. This positions the bit properly, giving maximum contact between the chuck jaws and the bit shank. KEYED MODELS To tighten chuck, insert key into each of the three key holes in succession and tighten firmly. The chuck can be released by using one hole only (Fig. 2). KEYLESS MODELS To tighten, hold the chuck collar firmly with one hand and securely tighten the chuck sleeve with the other hand (Fig. 3). !WARNING To prevent friction burns, or possible hand injury, do not loosen or tighten the chuck by using the power of the drill. CHUCK COLLAR CHUCK SLEEVE FIG. 2 FIG. 3 -7 Operating Tips You will extend the life of your bits and do neater work if you always put the bit in contact with the work before pulling the trigger. During the operation, hold the tool firmly and exert light, steady pressure. Too much pressure at low speed will stall the tool. Too little pressure will keep the bit from cutting and cause excess friction by sliding over the surface. This can be damaging to both tool and bit. DRILLING WITH VARIABLE SPEED The trigger controlled variable speed feature will eliminate the need for center punches in hard materials. The variable speed trigger allows you to slowly increase RPM. By using a slow starting speed, you are able to keep the bit from “wandering”. You can increase the speed as the bit “bites” into the work by squeezing the trigger. DRIVING WITH VARIABLE SPEED Variable speed drills will double as a power screwdriver by using a screwdriver bit in the drill mode. The technique is to start slowly, increasing the speed as the screw runs down. Set the screw snugly by slowing to a stop. Prior to driving screws, pilot and clearance holes should be drilled. FASTENING WITH SCREWS The procedure shown in (Fig. 4) will enable you to fasten materials together with your hammer drill in the drill mode without stripping, splitting or separating the material. First, clamp the pieces together and drill the first hole 2/3 the diameter of the screw. If the material is soft, drill only 2/3 the proper length. If it is hard, drill the entire length. Second, unclamp the pieces and drill the second hole the same diameter as the screw shank in the first or top piece of wood. Third, if flat head screw is used, countersink the hole to make the screw flush with the surface. Then, simply apply even pressure when driving the screw. Th...
