LASER ADJUSTMENT (FIG. 16, 17, 18)
NOTE: The laser assembly has been
installed and preset at the factory. It should,
however, be checked and any adjustments
made before operating the drill press. It
should also be rechecked periodically, as
constant machine vibration may cause it to
become misaligned.
1. Remove the guards (A1) to access the
laser assemblies.
2. Take a length of board (11) and draw a
perpendicular line (8) on one side using
a square.
3. Place a small drill bit (5) in the chuck (6),
then place the board (11) on the table on
edge against the drill bit with the marked
line side toward the back of the drill
press.
NOTE: The table should be in horizontal
position and locked. Verify that the line
(8) is perpendicular to the table.
4. Connect power to the drill press, and
turn on the laser using the button at the
front of the drill press head.
Vertical Alignment (FIG. 16, 17)
5. Loosen the three set screws (3), then
manually rotate the laser assembly
(1) and move the board from side to
side as required until the laser light (7)
lines up with the board marking (8) to
look like (9). Then carefully tighten the
three setscrews (3). Repeat step 5, if
necessary, until the light and marking
are aligned.
6. Adjust the other laser in the same
manner. Two parallel laser markings
should look like (9) and (10) in Fig. 17 –
the distance between the lines will vary
with board thickness; however, the lines
must be parallel.
Cross Hair Alignment (FIG. 16, 18)
7. Place board (12) flat on the table. Do
not allow the board to move from this
position; use clamps if needed. Bring
the bit down until it leaves a slight
perforation in the board; then raise it
back up.
8. Using a small screwdriver, loosen one
laser setscrew (2) and adjust (4) so the
laser line crosses the perforation (13).
Tighten setscrew (2).
9. Adjust the other laser assembly in
the same manner until the laser lines
form cross hairs (11) exactly over the
perforation in the board.
10.Tighten setscrew (2). Re-check the
vertical alignment to insure that the laser
lines did not shift during the tightening
process. The laser is now calibrated
properly and the location of your holes
can be centered at the cross hairs for
accurate drilling.
11.Assemble guards with pan head screws
over the laser on each side.
LASER LABEL (FIG. 19)
The label on your laser may include the
following symbols.
V .........................volts
mW......................milliwatts
nm.......................wavelength in nanometers
IIIa........................Class IIlA Laser
For your convenience and safety, the
following labels are on your laser. (Fig. 19)
WARNING! A laser light is radiated when
the laser guide is turned on. Avoid direct
eye contact. Always unplug the drill press
from the power source before making any
adjustments.
