18OPERATION cont.! Do not hold the chuck body with one hand and use the power of thedrill / driver to tighten the chuck jaws on the accessory bit. The chuck body could slip inyour hand, or your hand could slip and come in contact with the rotating accessory bit.This could cause an accident resulting in serious personal injury.WARNING:KEYLESS CHUCK (Fig. 7)The drill/driver has a keyless chuck which allows you to hand tighten or loosen accessory bitswithout the use of a chuck key.1. Grasp and hold the rear chuck collar with one hand (see Fig. 7).2. Rotate the front of the chuck with your other hand, clockwise (as viewed from the frontof the chuck), to CLOSE the chuck jaws and tighten (”GRIP”) the accessory bit in the jaws.3. Rotate the front of the chuck counterclockwise to OPEN the chuck jaws to loosen(”RELEASE”) the accessory bit from the chuck jaws (see Fig. 7a).Fig. 757319Companion9.6 VNOTE: ON THE VERY FRONT OF THE CHUCK there are “HANDS” that point thedirection to rotate the front of the chuck to “GRIP” or “RELEASE” the accessorybits.OPEN “RELEASE”CLOSE “GRIP”BUBBLE LEVELS (Fig. 8 an 8a)In order to insure a perfectright angle when drilling/drivinginto a workpiece, you can usethe built-in bubble level on theback of the drill / driver(see Fig. 8). The bubble levelis designed to work whendrilling / driving in either ahorizontal or vertical position.Line the air bubble up in theappropriate circle, and thedrill/driver is in a perpendicularangle to the workpiece. Thiswill insure that you drill/drivestraight into the workpiece.Fig. 8Align Bubble Level on Topfor Horizontal drillingFig. 8aAlign Bubble Levelon Back for Vertical drillingFig. 7a53 1710-4-07 Drill10300-1040019OPERATION cont.1. For normal drilling in wood, metal and plastics, turn and set the collar to the drillingposition symbol2. For screw driving, turn and set the collar to the desired setting 1 through 15. If you arenot sure of the appropriate setting using the guidelines in the chart (Fig. 9b),proceed as follows;• Set the collar to the lowest setting, “1”• Drive and tighten the first screw• If the clutch ratchets before the screw is tightened, increase the torque setting andcontinue to tighten the screw.• Repeat this process until you reach a torque setting that drives and tightens the screwwithout the clutch ratcheting.• Use that torque setting to drive and tighten the remaining screws.1 – 3 For driving small screws (least torque)4 – 6 For driving screws into soft material7 – 9 For driving screws into soft and hard materials10 – 12 For driving screws in hard woods13 – 15 For driving larger screwsFor normal to heavy twist drilling into all building materials (most torque)15 PLUS 1 ADJUSTABLE TORQUE CLUTCH (Fig. 9, 9a and 9b)This drill / driver is equipped with an adjustable clutch that has 16 different torque settings.These torque settings allow you to efficiently perform various drilling and screw drivingapplications. To adjust the clutch, hold the handle of the drill / driver with one hand and withthe other hand turn the clutch collar to the left or right (see Fig. 9), and line the desired setting(number or symbol) up to the embossed arrow on the top of the drill/driver’s motor housing(see Fig. 9a).Fig. 97 9511Fig. 9aUse the following guidelines to arrive at a proper torque setting.Fig. 9b57319CompanionDecreaseIncrease
