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) clock-
wise to eliminate the "play".
Note: A little bit of "play" is normal.
3.
Tighten the lock nut (1).
