To set the spindle return distance:
1. Lower the tooling/bit.
2. Thread the return height nut up the stud to
the desired height.

brated if it gets moved or has changed since the

The Model G1005Z has a depth stop that allows
you to lower the drill bit or milling tool to the same
point every time.
The depth stop consists of a stud attached to the
quill with two hex nuts that can be lowered or
raised on the stud, so the lower nut (depth nut) hits
a stop bracket when the drill bit is lowered. The
upper nut (jam nut) is then used to tighten against
the depth nut to secure it in place, so the depth
nut doesn't move with repeated operations.
Depth Stop
Quill Lock
The spindle can be locked in place to provide tool
stability when milling.
To lock the quill in place:
1. Lower the quill to the desired height.
2. Tighten the quill lock handle clockwise to lock
the quill in place, as shown in
Figure 14.
To unlock the quill:
1. While holding the downfeed handles, turn the
quill lock handle counterclockwise until the
quill is free to move.

The depth stop also features a return height
nut that is used to set the minimum spindle
return distance.
Figure 15 shows the various
components of the depth stop.
