2 Fig. 3 Fig. 5 MORSE TAPER SOCKETS Drill equipped with Morse Taper Sockets (Fig. 5) have a Morse Taper spindle sleeve inside the socket. Use drill bits with Morse Taper shanks corresponding to the Morse Taper sleeve. Be sure that the tang of the drill bit fits into the sleeve correctly. Tap the point of the drill bit lightly with a lead or rawhide hammer to seat the bit — do not use heavy blows. Removal of Drill Bit: Remove the spindle nut (See Fig. 5) completely by unscrewing it, and remove the spindle sleeve. Note that the tang of the drill bit protrudes through the rear of the sleeve. Tap the protruding tang lightly to remove the bit. SPADE HANDLE ASSEMBLY Assemble Spade Handle as shown at right. Tighten both screws to a snug fit, then tighten both screws an additional ’/2 turn. VARIABLE SPEED & REVERSING SWITCHES (Certain Tools) The Variable Speed Trigger Switch permits “FREE HAND” speed control—the farther the trigger is depressed, the higher the R.P.M. of the tool. A Switch Locking Button permits locking the trigger in the full “ON” position for continuous operation, or when using the Drill in a Vertical Stand. To lock the trigger “ON”, depress trigger fully and push in locking button, then gently release trigger. To release locking mechanism, depress trigger fully, then release it. For removing screws or easing drill bits out of tight holes, move the Reversing Switch to reverse the drill motor. The trigger switch must be released to the “OFF” position before moving the reversing switch. After any reversing operations, return switch to the forward position. CHUCKS AND SOCKETS CAUTION: Before touching chucks or sockets, or making any adjustments, always disconnect tool from power supply. GEARED CHUCKS 1) Always completely insert the shank of the drill bit or accessory in the chuck. This permits full gripping power and prevents cocking the chuck jaws. When using drill bits or accessories with 3 “Flats” on the shank, the chuck jaws should be located on the centers of these flats 2) Use all three holes in the chuck body to tighten the jaws (Fig. 1). Insert the chuck key into each hole and tighten as much as possible. To release the drill bit, use the chuck key in only one hole. 3) Use only a chuck key to tighten or loosen the chuck jaws. If key is lost order a new key at once. Order keys by number stamped on the chuck. 4) Geared chucks on Morse Taper Arbors (Fig. 2) are sometimes used on Vfe" or larger drills. Care must be taken when withdrawing from a drilled hole so that the arbor does not suddenly slip out of the socket in the drill and throw the operator off balance. The use of a Reversing Switch on a drill will prevent this by easing the drill bit from the hole. Removal and Attachment of Geared Chucks: 1) For geared chucks which are threaded directly on or into the drill (type of chuck usually used on V«” and some Vi” drills), use the following method: Place the chuck key in the chuck. Using a hammer or other similar object, strike the key sharply in the same direction that the tool normally runs. (See Fig. 3). This will loosen the chuck so that it can be unscrewed by hand. 2) Since special tools and techniques are required in the removal and attachment of geared chucks on Morse Taper Arbors (See Fig. 2), and of geared chucks known as "Key Drive Chucks" (See Fig. 4), it is recommended that this work be done by your B & D Service Branch. MOTOR Your tool is powered by a Black & Decker built motor. Be sure your power supply agrees with nameplate marking. VOLTS 50/60 Hz means Alternating Current ONLY. VOLTS DC 60 Hz means it will also operate on Direct Current. Voltage decrease of more than 10% will cause loss of power and over-heating. All B&D tools are factory-tested; if this tool does not operate, check the power supply. BRUSHES Carbon Brushes should be regularly inspected for wear if your Drill has exterior Brush Inspection Caps (Holgun Drills also have triangular Brush Inspection plates to facilitate brush inspection). When the cap is unscrewed, the spring and brush assembly may be withdrawn from the tool. Keep brushes clean and sliding freely in their guides. Carbon brushes have varying symbols stamped into them, and if the brush is worn down to the line closest to the spring, they must be replaced. New brush assemblies are available at Service Centers; see TOOLS, ELECTRIC in the Yellow Pages. If your Drill does not have exterior Inspection Caps, brush inspection should only be attempted by trained power tool repairmen like the men at B&D Service Centers. The inspection should be made every two to six months, depending upon usage. EXTENSION CORDS Tools that have 3 wire cords requiring grounding must only be used with extension cords that have 3-prong grounding type plugs and 3-pole receptacles. Only round jacketed extension cords should be used, and we recommend that they be listed by Underwriters Laboratories (U.L.) (C.S.A. in Canada). If the extension will be used ou...
