Higher speeds are better for drilling wood and composition boards, and for using abrasive and polishing accessories. The Reversing Switch is used for removing screws at lower speeds. It is lo-lated on the back of the handle (Fig. 2). To reverse the motor, release the trigger FIRST and then push the reversing lever toward “1”. After any reversing operations, return switch to forward position by pushing it toward T1. CHUCK KEY HOLDER 1. Push double-hole end of Holder through slot in other end of Holder (Figure A). 2. Slip loop over electric plug and draw loop tight around cord (Figure B). 3. Push ends of Chuck Key Handle through two holes in end of Holder (Figure C). Figure C 4 CAUTION: When drilling into walls, floors or wherever “live” electrical wires may be encountered, DO NOT TOUCH THE' CHUCK OR ANY FRONT METAL PARTS OF THE DRILL! Hold the Drill only by the plastic handle to prevent shock if you drill into a “live" wire. OPERATION DRILLING 1. Always unplug the tool when attaching or changing bits;or accessories. 2. Open chuck jaws by turning collar with fingers and insert shank of bit about %" 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 key counter clockwise in just one hole, then loosen chuck by hand. 3. 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. 4. 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. 5. 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. 6. 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. 7. Hold tool firmly to control the twisting action of the tool. 8. 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. 9. To minimize stalling on breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 10. 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.,...
