If the lock-on feature is engaged during use and the drill becomes disconnected from the power supply, disengage the lock-on feature immediately. WARNING: 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 7. 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, using the chuck key provided. Remove the chuck key.

DIRECTION OF ROTATION SELECTOR (FORWARD/REVERSE) See Figure 5, page 12. The drill is equipped with an auxiliary handle assembly. For ease of operation, use the handle with either the left or right hand. The handle can be rotated 360°. The direction of bit rotation is reversible and is controlled by a selector located above the switch trigger. With the drill held in normal operating position, the direction of rotation selector should be positioned to the left of the switch trigger for forward drilling. The drilling direction is reversed when the selector is to the right of the switch trigger. NOTICE: To adjust the auxiliary handle assembly, Loosen the handle assembly by turning the handle counterclockwise. Rotate the auxiliary handle assembly to the desired operating position. Securely tighten by turning the auxiliary handle clockwise. Be sure the auxiliary handle is securely tightened against To prevent gear damage, always allow the chuck to the depth stop clamp. This secures the depth stop rod at come to a complete stop before changing the direction the desired depth of cut. It also secures the auxiliary handle. of rotation. NOTE: For convenience and ease of starting threads, the To stop the drill, release the switch trigger and allow the chuck to come to a complete stop. NOTE: The drill will not run unless the direction of rotation selector is pushed fully to the left or right. Avoid running the drill at low speeds for extended periods of time. Running at low speeds under constant usage may cause the drill to become overheated. If this occurs, cool the drill by running it without a load and at full speed. hex nut has been trapped inside the molded slot in the auxiliary handle. The depth stop rod helps control the depth of drilled holes. NOTE: When properly installed, the teeth on the depth stop rod should be aligned with the teeth indicator on the depth stop clamp. Adjust the depth stop rod so that the drill bit extends beyond the end of the rod to the required drilling depth. TO INSTALL BITS See Figures 6 - 7, page 12. When drilling holes with the depth stop rod installed, the desired hole depth has been reached when the end of the rod comes in contact with the surface of the workpiece. Unplug the drill. Insert the chuck key and twist counterclockwise. 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. SELECTING HAMMER MODE OR DRILLING MODE See Figure 9, page 12.
