Batteries will still become depleted. 8. Unplug your tool’s charger from the power supply before disconnecting the charger from the tool. Under certain conditions, with the charger plugged in to the power supply, the exposed charging plug can be shorted by foreign material and may create a fire hazard. Foreign materials of a conductive nature, such as but not limited to, steel wool, aluminum foil, or any build up of metallic particles should be kept away from the charging plug. Unplug charger before attempting to clean. Trigger Switch & Reversing Button The drill is turned ON and OFF by pulling and releasing the trigger switch shown in Figure 1. The reversing button, also shown in Figure 1, switches the drill’s direction from forward to reverse. Two Speed Operation Your drill is equipped for two speed drilling. To operate at low speed, squeeze the trigger switch halfway. This will produce a low speed to be used for driving screws and starting holes without a centerpunch. Squeezing the trigger switch all the way will produce a high speed for normal drilling operation. NOTE: There is a slight pause between speeds. Keep squeezing the trigger, and the drill will start again. Screw Driving For driving fasteners, the reversing button should be pushed to the left as shown in Figure 1. Use reverse (button pushed to the right) for removing fasteners. When moving from forward to reverse, or vice versa, always release the trigger switch first. Keyless Chuck (9089KB, 9099KB) To insert a drill bit or other accessory: 1. Grasp the rear half of the chuck with one hand and use your other hand to rotate the front half in the counterclockwise direction, (Fig. 2). 2. Insert the bit or other accessory fully into the chuck, and tighten securely by holding the rear half of the chuck and rotating the front portion in the clockwise direction as viewed from the chuck end. WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may occur when changing accessories. Chuck & Key (9089, 9099) Turn chuck key counterclockwise to open chuck jaws, place bit in chuck as far as it will go and then pull it out far enough so that the chuck jaws do not touch the flutes of the bit. Tighten chuck collar by hand. Place chuck key in each of the three holes, and tighten in clockwise direction (Figure 3). It’s important to tighten the chuck with all three holes to prevent bit slippage. To release bit, turn chuck key counterclockwise in just one hole, then continue to loosen chuck by hand. Drilling • When attaching accessories in the drill chuck, it is important to securely tighten the chuck using all three holes to prevent slippage. When using a keyless chuck, hand tighten firmly. • Use sharp drill bits only. • Support and secure work properly, as instructed in the Safety Instructions. • Use appropriate and required safety equipment, as instructed in the Safety Instructions. • Secure and maintain work area, as instructed in the Safety Instructions. • Run the drill very slowly, using light pressure, until the hole is started enough to keep the drill bit from slipping out of it. • Apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting but not so much as to stall the motor or deflect the bit. • Hold the drill firmly to control its twisting action.. • DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN ATTEMPT TO START IT. DAMAGE TO THE DRILL CAN RESULT. •Minimize stalling on breakthrough by reducing pressure and slowly drilling through the last part of the hole. •Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jamming. •When using twist drill bits to drill holes in wood, it will be necessary to pull the bits out frequently to clear chips from the flutes. • Make sure switch turns drill on and off. WARNING: It is important to support the work properly and to hold the drill firmly to prevent loss of control which could cause personal injury. If you have any questions on how to properly operate tool, call: 1-800-54-HOW-TO (544-6986). Operation DRILLING IN WOOD Holes in wood can be made with the same twist drill bits used for metal or with spade bits. These bits should be sharp and should be pulled out frequently when drilling to clear chips from the flutes. 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 sulfurized cutting oil or lard oil; bacon grease will also serve the purpose. DRILLING IN MASONRY Use carbide tipped masonry bits. Refer to Drilling section. Keep even force on the drill but not so much that you crack the brittle material. A smooth, even flow of dust indicates the proper drilling rate. Maintenance Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part o...
