3. While charging, the charger may hum and become warm to touch. This is a normal condition and does not indicate a problem. 4. If the batteries do not charge properly – (1) Check current at receptacle by plugging in a lamp or other appliance. (2) Check to see if the receptacle is connected to a light switch which turns power off when you turn out the lights. (3) Move charger and drill to a surrounding air temperature of +40°F to +105°F. (4) If the receptacle and temperature are OK, and you do not get proper charging, take or send the tool and charger to your local Black & Decker service center. See "Tools Electric"’ in yellow pages. 5. The drill should be recharged when it fails to produce sufficient power on the jobs which previously were done easily. DO NOT CONTINUE to use the drill with its battery in a depleted condition. 6. To prolong battery life, avoid leaving the tool on charge for more than 2 days. Although overcharging is not a safety concern, it can significantly reduce overall battery life. 7. Since the unit is designed for cordless applications, use of the unit while plugged in is of no benefit. 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...
