7.4 Spindle return spring adjustment
The tension of the return spring, which raises the
spindle after drilling, has been pre-set by the
manufacturer. No further adjustment should be
attempted unless absolutely necessary. Should
spindle retraction weaken after long-term use of
the drill press, tighten the spring tension as follows.
1.
Grasp spring cover (A, Figure 7-3) firmly with
one hand. Loosen screw (B) just enough to
rotate spring cover past pin (C) and settle it on
the next notch. DO NOT remove spring cap or
allow it to rotate freely in your hand, or spring
may unwind.
2.
Rotate spring cover clockwise to decrease
spring tension; counter-clockwise to increase
spring tension.
3.
Re-tighten screw (B).
