Return spring adjustment
The
return spring
is located opposite the
downfeed
handle hub
and sets the tension for the downfeed
handle. It is adjusted at the factory and should not
need further adjustment.
If adjustment is deemed necessary:
1. Unplug machine from power source.
Refer to Figure 10:
2. Loosen
jam nut
(A) and
hex nut
(B). Do not
remove.
3. Pull out slightly the
coil spring cover
(C) while
firmly holding it. DO NOT allow the coil spring
cover to turn freely in your hand, or the spring will
unwind.
4. Rotate the coil spring cover (C) until notch on
cover engages with
tab
(E) on head casting. Turn
cover clockwise to decrease tension and counter-
clockwise to increase tension.
5. Tighten
hex nut
(B) firmly
by hand
against
cover
(C), then secure by tightening
jam nut
(A) against
hex
nut
(B).

Laser adjustment
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 use may cause it to become misaligned.
To align (refer to Figure 11):
1. Place
a
small
drill bit
(D) in the
chuck
(C), then
place
board
(F) flat on the table. Do not allow the
board to move from this position; use clamps if
needed.
Important
: The drill press table should
be in horizontal position and locked.
2. Bring the bit down until it leaves a
slight
perforation
in the board (E) then raise it back up.
3. Connect power to drill press, and turn on laser
using button at front of drill press head.
4. Using a 3mm hex wrench, loosen
setscrews
(A) on
both laser assemblies (only left side laser
assembly is shown in Figure 11).
5. Adjust (B) so the
laser line
(G) crosses the
perforation (E). Tighten
setscrew
(A).
6. Adjust the other laser assembly in the same
manner until both laser lines form
cross-hairs
(G,H) exactly over the
perforation
(E) in the
board.
7. Tighten both setscrews (A).
The laser is now calibrated properly and the location
of your holes can be centered at the crosshairs for
accurate drilling.
