_1= WARNING: Do not insert drill bit into chuck jaws and tighten as shown in figure 7. This could cause ddll bit to be thrown from drill resulting in possible serious personal injury or damage to the chuck. Fig. 7 REMOVING BITS See Figure 6. • Lock the switch trigger by placing the direction of rotation selector in center position. See Figure 3. • Loosen the chuck jaws from drill bit. • To loosen: grasp and hold the collar of the chuck with one hand, while rotating chuck body with your other hand. Note: Rotate chuck body in the direction of the arrow marked UNLOCK to loosen chuck jaws. See Figure 5. • Do not use a wrench to tighten or loosen the chuck jaws. • Remove drill bit from chuck jaws. 10 BIT STORAGE See Figure 8. When not in use, bits provided with your drill can be placed in the storage area located on the bottom of your ddll as shown in figure 8. BIT STORAGE AREA SCREWDRIVER BITS TO CLOSE TO OPEN Fig. 8 ADJUSTABLE TORQUE CLUTCH Your drill is equipped with an adjustable torque clutch for driving different types of screws into different matedals. The proper setting depends on the type of material and the size of screw you are using. TO ADJUST TORQUE • Identify the four torque indicator settings located on the front of your drill. See Figure 9. • Rotate adjusting ring to the desired setting. • 1 For driving small screws. • 2 For driving screws into soft matedaL • 3 For driving screws in hard wood. • <_11 For powerful screw driving or drilling. TO DECREASE ADJUSTING TORQUE RING LEVEL DRILLING See Figure 10. A convenient new feature provided with your drill is a level, It is recessed in the motor housing on top of your ddlL It can be used to keep ddll bits level during ddlling operations. Fig. 10 TOINCREASE TORQUE Fig. 9 11 _1= WARNING: Always wear safety goggles or safety glasses with side shields when operating tools. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury. DRILLING See Figure 11. When ddlling hard smooth surfaces use a center punch to mark desired hole location. This will prevent the ddll bit from slipping off center as the hole is started. However, the low speed feature allows starting holes without center punching if desired. To accomplish this, simply operate your drill at a low speed untilthe hole is started. The matedal to be drilled should be secured in a vise or with clamps to keep it from tuming as the drill bit rotates. Hold tool firmly and place the bit at the point to be ddlled. Depress the switch trigger to start tool. Move the drill bit into the workplace applying only enough pressure to keep the bit cutting. Do not force or apply side pressure to elongate a hole. When drilling metals, use a lightoil on the ddll bit to keep it from overheating. The oil will prolong the life of the bit and increase the ddlling action. Ifthebitjams inworkpieceoriftheddllstall_,release switch trigger immediately. Remove the bitfrom the workpiece and determine the reason for jamming. CHUCK REMOVAL See Figures 12, 13, and 14. The chuck must be removed in order to use some accessories. To remove: • Lock the switch trigger by placing the direction of rotation selector in center position. • Insert a 5/16 inch or larger allen wrench (hex key wrench) into the chuck of your drilland tighten the chuckjaws securely. • Tap the allen wrench sharply with a mallet in a clockwise direction. See Figure 12. This will loosen the screw in the chuck for easy removal. MALLET KEYLESS CHUCK CHUCK JAWS ALLEN WRENCH Fig. 12 Fig. 11 _1, WARNING: Be prepared for binding or bit breakthrough. When these situations occur, drill has a tendency to grab and kick opposite to the direction of rotation and could cause loss of control when breaking through material. If not prepared, this loss of control can result in possible serious injury. 12 CHUCKREMOVAL(co_Inued) • Open chuck jaws and remove allen wrench. Remove the chuck screw by turning it in a clockwise direction. See Figure 13. Note: The screw has left hand threads. Fig. 13 • Insert allen wrench in chuck and tighten chuck jaws securely. Tap sharply with a mallet in a countemlockwise direction. This will loosen chuck on the spindle. It can now be unscrewed by hand. See Figure 14. Fig. 14 TO RETIGHTEN A LOOSE CHUCK The chuck may become loose on spindle and develop a wobble. Also, the chuck screw may become loose causing the chuck jaws to bind and prevent them from closing. To tighten, follow these steps: Lock the switch trigger by placing the direction of rotation selector in center position. Insert allen wrench into chuck and tighten chuck jaws securely. Tap allen wrench sharply with a mallet in a clockwise direction. This will tighten chuck on the spindle. Open the chuck jaws and remove allen wrench. • Tighten the chuck screw. Note: The chuck screw has left hand threads. WARNING: When servicing, use only identical Craftsman replacement pads. Use of any other part may create a hazard or cause product damage. Avoid usin...
