3. Rotate lock ring (F) counterclockwise as far as
it will turn. You should be able to feel and hear
when the lock ring reaches the end of its
rotation.
4. Tighten lock handle (G).
5. The bit will now stop at the marked depth
when the downfeed handle is rotated.
6. To release the depth stop, loosen lock handle
(G).

NOTE: Method #2 allows rapid, fine adjustment to
the setting, as follows:
If the depth setting is found to be too shallow:
1. Hold downfeed handle (D) stationary while
slightly loosening lock handle (G).
2. Slightly rotate downfeed handle to lower bit to
the more accurate position.
3. Retighten lock handle (G). Depth is now set to
more accurate position.
If the depth setting is found to be too deep:
1. Loosen lock handle (G) while holding
downfeed handle stationary.
2. Slightly back off the lock ring (F), that is, rotate
it clockwise.
3. Slightly rotate downfeed handle to bring bit up
to more accurate depth.
4. Rotate lock ring (F) all the way counter-
clockwise.
5. Tighten lock handle (G). Depth is now set to
more accurate position.
8.9 Quill retraction lock
The quill can be held in the down position and
prevented from retracting, such as for operating a
sanding drum or to facilitate removal of chuck and
arbor.
To lock the quill in down position, proceed as
follows (Figure 24):
1. Loosen lock handle (G, Figure 24).
2. Rotate downfeed handle (D) to lower spindle
to the point at which it is to be locked, and hold
downfeed handle stationary in this position.
3. Rotate lock ring (F) clockwise all the way until
it stops. You should be able to feel and hear
when the lock ring reaches the end of its
rotation.
4. Tighten lock handle (G). You can now release
downfeed handle. The quill will remain in this
lowered position until released.
5. To release the quill, loosen lock handle (G).

The Laser Assembly has been installed and pre-
set at the factory. It should, however, be checked
for alignment and any adjustments made before
operating the drill press. It should be re-checked
periodically, as long-term machine vibration may
cause it to become misaligned.
