n With the power off (O), loosen the depth scale lock.
n Place workpiece on table. Adjust table until the tip of the
drill bit is just a little above the top of the workpiece, turn
the depth scale counterclockwise to zero.

depth scale.
n Tighten the depth scale lock.
n The chuck or drill will now be stopped after traveling

TO LOCK CHUCK AT DESIRED DEPTH
See Figure 20.
n With the switch off (O), loosen the depth scale lock.
n Turn the feed handles until the chuck is at the desired
