Calibrating Depth Stop; Tensioning Spindle Return Spring - Grizzly G7945 Owner's Manual

Calibrating Depth
Stop
The drill press comes fitted with a depth stop
to use when drilling multiple holes at the same
depth. The scale on this depth stop can be
calibrated if it ever becomes incorrect.
To calibrate the depth stop:
1. Loosen the return height nut and calibration
nut shown in Figure 44.

2. Use the calibration nut to zero the depth stop
scale with the stop bracket.
3. Hold the depth stop at zero, and tighten the
return height nut to hold the depth stop in
position.
4. Test the depth stop by measuring how far the
spindle actually moves with respect to where
you set the depth stop.

Tensioning Spindle
The tension of the spindle return spring makes the
spindle automatically return to the top (starting)
position when the downfeed handle is released.
This spring is pre-adjusted at the factory, and
typically will never need further adjustment during
the life of the drill press. However, additional
tension can be applied if the spindle stops
automatically returning to the top position.
