OPERATION
INSTALLING DEPTH GAUGE ROD
See Figure 11 - 12.
A depth gauge rod has been packed with your hammer drill
to assist you in controlling the depth of drilled holes.
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 material being
drilled.
Follow these steps to install and adjust the depth gauge
rod.
n
Loosen the auxiliary handle.
n
Insert the depth gauge rod through hole on the auxiliary
handle.
n
Adjust the depth gauge rod so that the drill bit extends
beyond the end of the rod to the required drilling depth.
n
Tighten the auxiliary handle securely. This secures the
depth gauge rod at the desired depth of cut. It also se-
cures the auxiliary handle.
