USINGTHE AUXILIARY HANDLE ASSEMBLY See Figure 5. An auxiliary handle is packed with the drill for ease of operation and to help prevent loss of control. The handle can be rotated 360 ° and it can also be mounted on the opposite side for left hand use. 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 the depth gauge clamp. This secures the depth gauge rod at the desired depth of cut. It also secures the auxiliary handle. NOTE: For convenience and ease of staring threads, the hex nut has been trapped inside the molded slot in the auxiliary handle. The depth gauge rod helps control the depth of drilled holes. NOTE: When properly installed, the teeth on the depth gauge rod should be aligned with the teeth indicator on the depth gauge clamp. Adjust the depth gauge rod so that the drill bit extends beyond the end of the rod to the required drilling depth. When drilling holes with the depth gauge rod installed, the desired hole depth has been reached when the end of the rod comes in contact with the surface of the workpiece.
