The insulation system is for added protection against injury resulting from a possible electrical insulation failure within the tool. CAUTION: When servicing Double-Insulated Tools, use ONLY IDENTICAL REPLACEMENT PARTS. Replace or repair damaged cords. EXTENSION CORD When using this drill at a considerable distance from power source, an extension cord of adequate size must be used for safety, and to prevent loss of power and over-heating. For a 120-volt tool, the minimum size of the wires in any extension cord up to 75 feet long must be 18-gauge (American Wire Gauge). From 75 to 100 feet, 16-gauge wire is required throughout the extension. 220-volt tools require a minimum wire size of only 18-gauge in extension cord lengths up to 100 feet long. (NOTE: 16-gauge wire is heavier than 18-gauge wire and will carry current for longer distances without a voltage drop.) Before using Extension Cords, inspect them for loose or exposed wires and damaged insulation. Make any needed repairs or replacement before using your power tool. CHUCK UNPLUG DRILL Turn collar to open chuck jaws. Insert bit into chuck as far as it will go. Tighten chuck collar by hand.. Place chuck key in each of the three holes, and tighten in clockwise direction. - It’s'ini* portant to tighten chuck with all three holes. To release bit, turn chuck key counterclockwise in just one hole, then loosen chuck ' by hand. To remove the chuck from the Drill, for using a threaded shank accessory or for chuck replacement, first unplug tha* tool. Insert the key in the chuck and * tap it sharply in the direction the tool normally rotates—see at right. This will loosen the chuclc shank threads and the chuck may be unscrewed by hand. Do not lubricate the three chuck jaws or the inside of the chuck; however, a light film of oil can be applied to the outside of the chuck to prevent any rust from forming. 4. OPERATION CARE IN DRILLING Twist drills mm brittle and will break if enough bending stress is applied. To avoid stress on the drill bit, try extending your index finger along the side of the drill-housing v 1th your middle finger on the trigger. Remember — guide the tool, don’t force it! Should the tool become overheated., run it free of any load at maximum speed. The drill will cool faster by running it without load. DRILLING IN METAL Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass whi**h shouH be drilled dry. The cutting lubricsnt that works best is sulphurized cutting oil. 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 Chios from the flutes» For larger holes, use Power Drill Wood Bits with a shank size that will fit your drill's chuck. Work that is apt to splinter should be backed up vuth a block of wood. Let up on the pressure just before the tip cuts through, this will give a good clean hole.
