When not in use, before servicing; when changing accessories such as blades, bits, cutters, etc. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on. 18. AVOID ACCIDENTAL STARTING. Don’t carry plugged-in tool with finger on switch. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 14. 15. 16. 17. GROUNDING EVERY ELECTRIC TOOL SHOULD BE GROUNDED while in use,to protect the operator against shock. This unit is equipped with approved 3-conductor cord and 3-blade grounding type attachment plug to be used with the proper grounding type receptacle. The green colored conductor in the cord is the grounding wire. Never connect the green wire to a “live" terminal. If your unit requires less than 150 volts, it has a plug that looks like fig. “A”. A special grounding adapter {Fig. “B”) is available from your dealer to permit using 2-wire receptacle until the correct receptacle is properly »installed. The green grounding wire extending from the side of the adapter must be connected to a PERMANENT GROUND such as a properly grounded outlet box. If the unit requires from 150 to 250 volts it has a plug like Figure 4IC”. No adapter is available and it should be used in the proper standard matching 3-wire grounding receptacle.

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. NOTE; Use lower speeds for STARTING HOLES WITHOUT A CENTER PUNCH, DRILLING IN METAL OR PLASTICS, DRIVING SCREWS, DRILLING CERAMICS, OR MIXING PAINT. Higher speeds are better for DRILLING WOOD AND COMPOSITION BOARDS, AND FOR USING ABRASIVE AND POLISHING ACCESSORIES. CABLE The cable is the life-line of your tool. Keep it clean by wiping occasionally to remove any grease or oil. Don't let it become kinked. Avoid dragging it across sharp surfaces. Do not lift the tool by the cable. When using the tool at a considerable distance from power source, a properly grounded extension cable of adequate size must be used to prevent loss of power and over-heating. Use table at right for 115 Volt tools. For 220 tools, use wire size of l/z the contemplated cable length. DRILLING INSERTING DRILL BIT IN CHUCK Turn collar to open chuck jaws. Place bit in chuck so that end rests on chuck bottom. 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. This is a safety feature that prevents bit slippage and motor damage. To release bit, turn chuck key counterclockwise in just one hole, then loosen chuck by hand. STARTING THE HOLE — WITH A VARIABLE SPEED DRILL, using a slow speed will enable you to start the hole accurately in most cases without the need for center punching. CARE IN DRILLING Twist drills are brittle and will break if enough bending stress it applied. To avoid stress on the drill bit, try extending your index finger along the side of the drill-housing with your middle finger on the trigger. Remember— guide, the tool, don't force it! Should the tool become overheated, run it with no load. Because of the drill’s construction, it will cool faster running than by stopping it. DRILLING IN METAL Use a cutting lubricant when drilling metals. The exceptions are 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 turpentine or kerosene. DRILLING IN WOOD Holes in wood can be made with the same twist drills used for metal. These bits may overfieat unless pulled out frequently to clear chips from the flutes. Work that is apt to splinter should be backed up with a block of wood. Let up on the pressure just before the tip cuts through, this will give a good clean hole.

Strike the key sharply with a piece of wood in the direction that the chuck normally rotates. This will loosen the chuck so that it can be unscrewed by hand.
