ASSEMBLY & ADJUSTMENTS

SPINDLE RETURN SPRING (FIG. 17)
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 (Fig. 17 - 1) to hold the spring in
place.
3. Loosen the two housing nuts (Fig. 17 - 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 (Fig. 17 - 3), carefully pull
spring housing out until it clears the raised stop (Fig. 17 - 4).
5. Turn the housing so that the next notch (Fig. 17 - 5) is engaged with
the raised stop (Fig. 17 - 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. 18)
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 outer nut (Fig. 18 - 1) about 1/8 inch.
2. Without obstructing the upward and downward motion of the spindle,
turn the screw (Fig. 18 - 2) clockwise to eliminate the “play.”
NOTE: A little bit of “play” is normal.
3. Tighten the lock nut (Fig. 18 - 1).

NOTE: Adjustments for
the correct function of
your drill press return
spring have been done by
the factory. Please do not
modify them. However,
prolonged use of the drill
press may make some
readjustments necessary.
