USING
THE 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 oper-
ating 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.
