Spindle return spring (Fig. 19)
The spindle is equipped with an auto-return mechanism. The
main components are a spring and a notched housing. The
spring was properly adjusted at the factory and should not be
readjusted unless absolutely necessary.
1. Unplug the drill press.
2. Place a screwdriver into the loop (1) to hold the
spring in place.
3. Loosen the two housing nuts (2) approximately 1/4" (6
mm). Do not remove the nuts from the threaded shaft.
Do not allow the spring or spring housing to slip out
of control.
4. While firmly holding the spring housing (3), carefully pull
the spring housing out until it clears the raised notch (4).
5. Turn the housing so that the next notch (5) is
engaged with the raised notch (4).
To increase the spindle return tension, turn the
spring housing counter-clockwise.
To decrease the tension, turn the spring housing
clockwise.
6. Tighten the two housing nuts. Do not overtighten the two
nuts. If the nuts are tightened too much, the movement
of the spindle and feed handles will become sluggish.

Angular "play" of the spindle (Fig. 20)
Move the spindle to the lowest downward position and hold in place. Try to make the spindle revolve around its
axis while also moving it with a side motion. If there is too much "play", proceed as follows:
1. Loosen the lock nut (1).
2. Without obstructing the upward and downward motion of the spindle, turn the screw (2) clockwise to
eliminate the "play". Note: A little bit of "play" is normal.
3. Tighten the lock nut (1).
