movement of the the spindle. (A little
play in the spindle is normal.)

Remove the cap (3), loosen the hex nut (4)
and then remove the hub assembly (7).
2. Lower the table for additional clearance.

removing only the lock nut (6).

notch, loosen the inner nut (10) just until
the notch (11) disengages from the boss
(12) on the drill press head.

unwind.

counterclockwise with the screwdriver,
engaging the next notch.
6. Lower the quill to the lowest position
by rotating the feed handle in a
counterclockwise direction while holding
the spring cap (9) in position.
7. If the quill moves up and down as easily
as you desire, tighten the inner nut (10)
with the adjustable wrench. If too loose,
repeat steps 3 through 5 to tighten. If
too tight, reverse steps 4 and 5. DO
NOT OVERTIGHTEN and restrict quill
movement.
