QU_LL RETURN SPRING (FIG, R)
The quill return spring may need adjustment if the tension
causes the quill to return too rapidly or too slowly.
t. Lower the table for additional clearance.

spring cap (2). Hold it in place while loosening and
removing only the outer jam nut (3).
3. 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.
CAUTION: DO NOT REMOVE THIS INNER NUT,
because the spring will forcibly unwind,
4. Carefully turn the spring cap (2) counterclockwise with
the Screwdriver, engaging the next notch.
5. Lower the quill to the lowest position by rotating the
feed handle in a counterclockwise direction while
holding the spring cap (2) in position,
6. If the quill moves up and down as easily as you
desire, tighten the standard nut (4) with the adjustable
wrench. If too loose, repeat steps 2 through 5 to
tighten. If too tight, reverse steps 4 and 5.
