Referring to Figure 20:
1. Disconnect machine from power source.
2. Pry off cap (H, Figure 20) and remove hex nut
and two washers (I). Pull off hub (J).
3. Loosen two inner hex nuts (K) Do not remove.
4. Pull out slightly the coil spring cover (L) while
firmly holding it. DO NOT allow the coil spring
cover to turn freely in your hand, or the spring
will unwind.
5. Rotate coil spring cover until tab (M) on the
spring retainer engages the next notch in coil
spring cover. Rotate coil spring cover
counterclockwise to increase spring tension,
clockwise to decrease.
6. Make sure coil spring cover is pushed back in,
then tighten two hex nuts (K). Do not over
tighten. The hex nuts should be tightened
against each other.
7. Re-install hub, washers, hex nut and cap.

8.7 Laser adjustment
Referring to Figures 21 through 24:
Do not look directly into the
laser beam or view it directly with optical
instruments. See Figure 21.

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 22) and draw
a perpendicular line (B) on one side using a
square.
2. Insert 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 22) is perpendicular to the table.
3. Connect power to the drill press, and turn on
the laser using the button at the front of the
drill press head.

Vertical Alignment
4. Use the socket head screw (H, Figure 23)
located toward front of laser assembly, to
adjust verticality of laser line. 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 other laser in the same manner.
Two parallel laser markings should look like F
and G in Figure 22. The distance between the
lines will vary with board thickness; however,
the lines must be parallel.

6. Place board (K, Figure 24) flat on table. Do not
allow board to move from this position; use
