-26- G4015Z Lathe/Mill
Fine Down Feed
Quill Lock Lever
The up and down motion of the drill press spin-
dle is controlled just like any other drill press with
a
Quill Lever . But unlike most drill presses, the
Model G4015Z is supplied with a Fine Down
Feed knob, indicated by the arrow in Figure 27 .
To activate this feature, rotate the Quill Lever
while depressing the black knob in the middle of
the center of the hub as in
Figure 27. The knob
will engage and the spindle will no longer move
using the
Quill Lever . Rotating the Fine Down
Feed knob in a clockwise direction will cause the
spindle to go down. To disengage this feature,
rotate the
Fine Down Feed knob and pull on the
knob in the center of the hub. Rotating the hand-
wheel will always aid in engaging and disengag-
ing this feature.
The height of the spindle can be locked with the
Quill Lock Lever. Set the desired height with the
Quill Lever and turn the lever down. The lever
can be clearly seen on the bottom right hand cor-
ner of
Figure 27 .

Figure 26. Loosen stud to pivot belt tensioner.
To change belt position:
1. Unplug the machine.
2. Remove the Upper Belt Guard , loosen the
cover securing stud and pivot the belt ten-
sioner to relax tension on the belt.
See
Figure 26.
3. While slowly turning a pulley, roll the belt up
or down to the desired sheave. It is always
easier to roll off of the larger pulley onto a
smaller pulley.
Do not allow fingers to
become trapped between belt and pulley.
4. Pivot the belt tensioner until the belt is tight
and secure the tensioner by tightening the
stud.
5. Replace belt guard.
