Referring to Fi gure 20:
1. Dis connect machine from power sour ce.
2. Pry off cap (H, Figure 20) and rem ove hex nut
and two wash ers (I). Pull off h ub (J).
3. Loosen two inn er 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 t ur n f reely in your hand, or t he spr ing
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,
clockwis e 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 oth er.
7. R e-insta ll hub, washers, hex nut and cap.

8.7 Laser adjustment
Referring to Fi gures 21 through 24:
Do not look directly into the
laser beam or view it directly with optical
instruments. See Figu re 21.
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 th e 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 m ove 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
