8 • To tighten the chuck jaws on drill bit; grasp and hold the collar of the chuck with one hand, while rotating the chuck body with your other hand. Note: Rotate the chuck body in the direction of the arrow marked LOCK to tighten chuck iaws. • Do not use a wrench to tighten or loosen the chuck jaws. ,_ WARNING: Do not insert drill bit into chuck jaws and tighten as shown in figure 9. This could cause drill bit to be thrown from drill resulting in possible serious personal injury or damage to the chuck. . REMOVING BITS See Figure 8. • Lock the switch trigger by placing the direction of rotation selector in center position. See Figure 2. • 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. • Do not use a wrench to tighten or loosen the chuck jaws. • Remove drill bit from chuck jaws. ADJUSTABLE TORQUE CLUTCH Your drill is equipped with an adjustable torque clutch for driving different types of screws into different materials. The proper setting depends on the type of material and the size of screw you are using. TO ADJUST TORQUE • Identify the twenty four torque indicator settings located on the front of your drill. See Figure 10. • Rotate adjusting ring to the desired setting• • 1 -4 For driving small screws. • 5 -8 For driving screws into soft material. • 9 -12 For driving screws into soft and hard materials. • 13 -16 For driving screws in hard wood. • 17 -20 For driving large screws. • 21 -,11 For heavy drilling.

When not in use, bits provided with your drill can be placed in the storage area located on the top of your drill as shown in figure 11. SCREWDRIVERBITS BIT STORAGEAREA Fig. 11 ,&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. LEVEL DRILLING See Figure 12. A convenient new feature provided with your drill is a level. It is recessed in the motor housing on top of your drill. It can be used to keep drill bits level during drilling operations. | LEVEL Fig. 13 When drilling hard smooth surfaces use a center punch to mark desired hole location. This will prevent the drill 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 until the hole is started. The material to be drilled should be secured in a vise or with clamps to keep it from turning as the drill bit rotates. Hold tool firmly and place the bit at the point to be drilled. Depress the switch trigger to start tool. Move the drill bit into the workpiece applying only enough pressure to keep the bit cutting. Do not force or apply side pressure to elongate a hole. ,_IL 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. When drilling metals, use a light oil on the drill bit to keep it from overheating. The oil will prolong the life of the bit and increase the drilling action. If the bit jams in workpiece or if the drill stalls, release switch trigger immediately. Remove the bit from the workpiece and determine the reason for jamming. Fig. 12 11 CHUCK REMOVAL Insert hex key wrench in chuck and tighten chuck jaws securely.

It can now be unscrewed by hand. accessories. To remove: See Figure 16, • Lock the switch trigger by placing the direction of rotation selector in center position. • IRsert a 5/16 inch or larger hex key wrench into the chuck of your drill and tighten the chuck jaws securely. • Tap the hex key wrench sharply with a mallet in a clockwise direction. See Figure 14. This will loosen the sct:ew in the chuck for easy removal. MALLET KEYLESSCHUCK Fig. 16 TO RETIGHTEN A LOOSE CHUCK The chuck may become loose on spindle and develop a wobble.
