11. Slightly back off the lock ring (J), that is, rotate
it clockwise .
12. Slightly rotate downfeed handle to bring bit up
to more accurate depth.
13. Rotate lock ring (J) all the way counter-
clockwise.
14. Tighten lock handle (H). Depth is now set to
more accurate position.
8.4 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 8-4):
1. Loosen lock handle (H).
2. Rotate downfeed handle (G) 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 (J) clockwise all the way until it
stops. You should be able to feel and hear when
lock ring reaches the end of its rotation.
4. Tighten lock handle (H). You can now release
downfeed handle. The quill will remain in this
lowered position until released.
5. To release the quill, loosen lock handle (H).
8.5 Work stop
The work stop (shown mounted in Figure 6-9) is
used for repetitive drilling in boards of identical
length. Flip up the work stop to slide it along the
fence or to remove it. Pull it down to tighten in
position.
8.6 Laser adjustment
Do not look directly into the
laser beam or view it directly with optical
instruments. See Figure 8-7.
Figure 8-7
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.
1. Take a length of board (A, Figure 8-8) and draw
a perpendicular line (B) on one side using a
square.
2. Secure a small drill bit (C) in chuck (D), then
place board (A) on the table on edge against
drill bit with the marked-line side toward the
back of the drill press.
Important : The table should be in horizontal
position and locked. Verify that the line (B,
Figure 8-8) is perpendicular to the table.
3. Connect power to the drill press, and turn on the
laser using the switch at the front of the drill
press head.
Figure 8-8
Vertical Alignment
4. Use the screw located toward front of laser
assembly, to adjust verticality of laser line
(Figure 8-9). Turn screw as needed (2.5mm hex
wrench), and move board side-to-side as
needed, until laser light (E) aligns with board
marking (B).
5. Adjust the opposite laser in the same manner.
Two parallel laser markings should look like F
and G in Figure 8-8. The distance between the
lines will vary with board thickness; however,
the lines must be parallel.
