To release bit, turn key counterclockwise in just one hole. Chuck Key Holder (Figure 2) 1. Push double-hole end of holder through slot in other end of holder. 2. Slip loop over electric plug and draw loop tight around cord. 3. Push ends of chuck key handle through two holes in end of holder. Chuck Removal Insert straight end of chuck key handle into chuck as shown in Figure 3. Using a wooden mallet or similar object, strike key sharply in a counterclockwise direction. This will loosen the chuck so that it can be unscrewed by hand. 3 Drilling 1. Always turn off tool and disconnect from power supply 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 If drilling thin material, use a “back-up” block to prevent damage the material. 4. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit biting, but do not push hard enough to stall the motor or deflect the bit. 5. Hold tool firmly to control the twisting action of the drill. 6. IF DRILL STALLS, it is usually because it is being overloaded. 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. 7. To minimize stalling on breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. 9. For optimum control and comfort, the drill may be grasped in one of the following illustrated manners: Around the neck of the drill using one or two fingers to operate the paddle switch as in Figure 4, in an inverted position with the heel of the hand pushing on the head of the drill and one or two fingers on the paddle switch English FIG. 4 FIG. 6 FIG. 5 PADDLE SWITCH FIG. 4 FIG. 6 FIG. 5 PADDLE SWITCH as in Figure 5, or holding the head of operating the paddle switch with the other end of the drill as in Figure 6. EnglishDrilling in Wood Holes in wood can be made with the same twist These bits may overheat unless pulled out frequently from the flutes. For larger holes, use spade bits, power hole saws. Work that is likely to splinter should be backed up with a block of wood. 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. Drilling in Masonry Use carbide tipped masonry bits at low speeds. Keep even force on the drill but not so much that you crack the brittle materials. A smooth, even flow of dust indicates the proper drilling rate. Motor Brushes Your tool will stop when the brushes wear out (down to about 3/16" (5mm) long). This prevents damage to the motor.
