Sears 172.103 Keyless Chuck Fig, Plus 1 Adjustable Torque Clutch , 9a and 9b, Bubble Levels an 8a

OPERATION cont.

KEYLESS CHUCK (Fig. 7)

The drill/driver has a keyless chuck which allows you to hand tighten or loosen accessory bits without 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 front

of 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).

OPERATION cont.

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 driving applications. To adjust the clutch, hold the handle of the drill /driver with one hand and with the 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).

NOTE: ON THE VERY FRONT OF THE CHUCK there are “HANDS” that point the direction to rotate the front of the chuck to “GRIP” or “RELEASE” the accessory bits.

Use the following guidelines to arrive at a proper torque setting.

!WARNING: Do not hold the chuck body with one hand and use the power of the drill / driver to tighten the chuck jaws on the accessory bit. The chuck body could slip in your 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.

BUBBLE LEVELS (Fig. 8 an 8a)

Fig. 9b

1 – 3 For driving small screws (least torque)

4 – 6 For driving screws into soft material

7 – 9 For driving screws into soft and hard materials

10 – 12 For driving screws in hard woods

13 – 15 For driving larger screws

In order to insure a perfect right angle when drilling/driving into a workpiece, you can use the built-in bubble level on the back of the drill / driver

(see Fig. 8). The bubble level is designed to work when drilling / driving in either a horizontal or vertical position. Line the air bubble up in the appropriate circle, and the drill/driver is in a perpendicular angle to the workpiece. This will insure that you drill/drive straight into the workpiece.

For normal to heavy twist drilling into all building materials (most torque)

1.For normal drilling in wood, metal and plastics, turn and set the collar to the drilling position symbol

2.For screw driving, turn and set the collar to the desired setting 1 through 15. If you are not 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 and continue to tighten the screw.

•Repeat this process until you reach a torque setting that drives and tightens the screw without the clutch ratcheting.

•Use that torque setting to drive and tighten the remaining screws.
