OPERATION KEYLESS CHUCK See Figure 4, page 11. Adjusting TORQUE See Figure 6, page 11. The drill has a keyless chuck to tighten or release drill bits in the chuck jaws. The arrows on the chuck indicate which direction to rotate the chuck body in order to LOCK (tighten) or UNLOCK (release) the drill bit. There are twenty-four torque indicator settings located on the front of the drill. Rotate the adjusting ring to the desired setting. • 1 - 4 For driving small screws WARNING: Do not hold the chuck body with one hand and use the power of the drill to tighten the chuck jaws on the drill bit. The chuck body could slip in your hand, or your hand could slip and come in contact with the rotating drill bit. This could cause an accident resulting in serious personal injury. • 5 - 8 For driving screws into soft material • 9 - 12 For driving screws into soft and hard materials • 13 - 16 For driving screws into hard wood • 17 - 24 For driving large screws • For heavy drilling AutoShift™ See Figure 6, page 11. INSTALLING BITS See Figures 4 - 5, page 11. Lock the switch trigger by placing the direction of rotation selector in the center position. Open or close the chuck jaws to a point where the opening is slightly larger than the bit size you intend to use. Also, raise the front of the drill slightly to keep the bit from falling out of the chuck jaws. Insert the drill bit. During drilling, if the load increases so that more torque is required, the drill automatically shifts from high speed to low speed. The green "SPEED" LED will light when the switch trigger is depressed. The blue "POWER" LED indicates that more torque is required and the drill has automatically shifted into low speed. The variable speed switch trigger should be used to control speed. WARNING: DRILLING See Figure 7, page 11. Make sure to insert the drill bit straight into the chuck jaws. Do not insert the drill bit into the chuck jaws at an angle then tighten, as shown in figure 5. This could cause the drill bit to be thrown from the drill, resulting in possible serious personal injury or damage to the chuck. Tighten the chuck jaws securely on the drill bit. Note: Rotate the chuck body in the direction of the arrow marked LOCK to tighten the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws. REMOVING BITS See Figure 4, page 11. Lock the switch trigger by placing the direction of rotation selector in the center position. Rotate the chuck sleeve clockwise to open the chuck jaws. Note: Rotate the chuck body in the direction of the arrow marked UNLOCK to loosen the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws. Remove the drill bit. adjustable torque clutch This product 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. Check the direction of rotation selector for the correct setting (forward or reverse). Secure the material to be drilled in a vise or with clamps to keep it from turning as the drill bit rotates. Hold the drill firmly and place the bit at the point to be drilled. Depress the switch trigger to start the drill. Move the drill bit into the workpiece, applying only enough pressure to keep the bit cutting. Do not force the drill or apply side pressure to elongate a hole. Let the tool do the work. WARNING: Be prepared for binding at bit breakthrough. When these situations occur, the drill has a tendency to grab and kick in the opposite direction 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 hard, smooth surfaces, use a center punch to mark the desired hole location. This will prevent the drill bit from slipping off-center as the hole is started. 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. 9 − English
