Make any needed repairs or replacement before using your power tool. Your Drill is provided with an electric cord which attaches and detaches easily from the tool. This feature permits storing the tool on a shelf, or on pegboard, without wrapping the cord around the tool. It permits cord repair or replacement without tool disassembly. The cord fits into the bottom of the tool handle as shown in Figure 1. Make sure that switch is “OFF” before inserting cord. Buttons must be in the unlocked position shown in Figure 1 to allow cord to be inserted. Pushing both buttons at the same time in the direction shown (Figure 2) locks the cord to the handle. B&D Extension Cords (16 Gauge, U.L. listed for indoor and outdoor use) are available with female plug molded to fit directly into B&D tools with detachable cord feature. They also can be used with other tools. There are 2-wire cords for double-insulated tools and 3-wire cords for use with both double-insulated tools and tools that require grounding. EXTENSION CORD DETACHABLE CORD FIG.t FIG.2 4. 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. Center-punch an indentation at the point to be drilled. This will overcome the tendency of the bit to slip around on a smooth surface. Place the tip of the bit in the indentation and turn motor “ON”. NOTE: With Variable Speed Drills, holes can be started at low speed without the need for center punching. 5. 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. 6. Hold drill firmly to control the twisting action of the drill. 7. 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. 8. To minimize stalling on breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 9. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. 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 sulphurized cutting oil or lard oil; bacon grease will also serve the purpose. Aluminum is best drilled with kerosene. 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. To remove the chuck from the Drill (for using a threaded shank accessory or for chuck replacement) first unplug the tool. If your Drill has a reversing switch, open the chuck and remove screw in bottom of chuck (left hand thread). Insert the key in the chuck and tap it sharply in the direction the tool normally rotates — see at right. This will loosen the chuck shank threads and the chuck may be unscrewed by hand. ...
