ASSEMBLY AND ADJUSTMENTS
SPINDLE / QUILL (FIG. J)
Rotate the feed handles counterclockwise to lower spindle to
its lowest position. Hold the chuck and move it front to back.
If there is excessive play, proceed with the following
adjustments:
• Loosen the lock nut (1) located on the right side of the
drill press, using a 13 mm wrench.
• Turn the screw (2) clockwise to eliminate the play, using
a slotted screwdriver, but without obstructing the upward
movement of the the spindle. (A little play in the spindle
is normal.)
• Tighten the lock
nut (1).
Fig. J
QUILL RETURN SPRING (FIG. K)
The quill return spring may need adjustment if the quill return
speed is too rapid or too slow. This spring is located on the
left side of the drill head.
• Lower the table for additional clearance.
• Place a screwdriver in the lower front notch (1) of the
spring cap (2). Hold it in place while loosening and
removing only the outer jam nut (3), using a 16 mm
wrench.
• With the screwdriver still engaged in the notch, loosen the
inner nut (4) just until the notch (5) disengages from the
boss (6) on the drill press head.
NOTE: DO NOT REMOVE THIS INNER NUT, because
the spring will forcibly unwind.
• Carefully turn the spring cap (2) counterclockwise with
the screwdriver, engaging the next notch.
• Lower the quill to the lowest position by rotating the feed
handle in a counterclockwise direction while holding the
spring cap (2) in position.
• If the quill moves up and down as you desire, tighten the
inner nut (4) close against the spring cap with a
adjustable wrench. If too loose, repeat above steps 3
through 5 to tighten. If too tight, reverse steps 4 and 5.
• Secure the outer nut (3) against the inner nut with
the wrench.
NOTE: DO NOT OVERTIGHTEN and restrict quill
movement.

BELT TENSION (FIG. L)
WARNING
To avoid injury from an accidental start, ALWAYS
make sure the switch is in the "OFF" position, the
switch key is removed, and the plug is not connected
to the power source outlet before making belt
adjustments.

• To unlock the belt tension, turn the belt tension lock
knob (1) on the right side of the drill press head
counterclockwise.
• Pull the motor (2) toward the front of the drill press to
loosen the belt tension.
• Position the belt on the correct pulley steps for
the desired speed.
• Push the motor away from the drill press head until the
belt is properly tensioned.

approximately 1/2 inch when pressed at its center.
• Tighten the belt tension lock knob (1) to secure the motor
in position. Close pulley cover.

LASER ADJUSTMENT (FIG. M, N, O)
NOTE: The laser assembly has been installed and preset at
the factory. However, it should be checked and adjusted
before operating the drill press. It should also be re-checked
periodically, as constant machine vibration may cause it to
become misaligned.
WARNING
A laser light is radiated when the laser guide is turned
on. Avoid direct eye contact. Remove the safety key
from the main on/off switch before making an
adjustment to the laser guides. (see page 12
ON/OFF SWITCH PANEL for more details)
• Take off the cover (1) by removing the screws (2) using a
Phillips Screwdriver to access the laser assembly. (Fig. M)
• Take a length of board (6) and draw a perpendicular
line (7) on one side of board using a square. (Fig. N)
• Place a small drill bit (8) into the chuck (9), then place the
board (6) on the table. The board edge against the drill
bit (8) 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 marked line (7) is perpendicular
to the table.
• Connect power to the drill press, and turn on the laser by
pressing the button at the front of the drill press head.
