1). To use tool in “Forward” rotation move lever to left side of tool, to “Reverse” the rotation of the bit move the lever to the right side of the tool. ! 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. Changing gears: Change gear position only with the motor at a complete standstill. To change gears rotate the gear selection lever. If you have difficulties changing from one gear to the other, turn the chuck by hand until the gears engage (Fig. 1). AUXILIARY HANDLE The auxiliary handle will provide additional control, support and guidance for the drill. The handle is adjustable to any position around the 360° handle collar mount. Installing side handle: Slide the handle over the handle collar mount. Securely tighten wing knob (A). DEPTH GAUGE Your drilling depth can be pre-set and/or repeated by using the depth gauge. Setting depth: After the auxiliary handle is installed, slide the depth gauge to desired depth and securely tighten wing knob (B). 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. To tighten chuck, insert key into each of the three key holes in succession and tighten clockwise firmly. The chuck can be released by using one hole only (Fig. 2). -7 FIG. 2 Counter Clockwise Clockwise 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 FASTENING WITH SCREWS The procedure shown in (Fig. 3) 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. The screw shank clearance hole in the first piece allows the screw head to pull the pieces tightly together. 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. The adjustable screw drill accessory will do all of these operations quickly and easily. Screw drills are available for screw sizes No. 6, 8, 10 and 12. FASTENING 2.

BRUSHING PRESSURE You will drill a cleaner hole if you ease up on 1. Remember, the tips of a wire brush do the the pressure just before the bit breaks through work.
