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 jam nut and calibration nut shown
in Figure 46.

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
jam 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.
Feed Shaft Spring
Te ns io n
The feed shaft return spring is adjusted at the
factory; however, during the life of the drill press
you may want to adjust the feed shaft return
spring so the feed shaft return pressure suits your
operating needs.

Wear safety glasses when
adjusting springs. Serious
injury may occur if this
warning is ignored!
To adjust the feed shaft spring tension:
1. UNPLUG THE DRILL PRESS!
2. Wipe off any oil on the spring lock cover so it
does not slip in your fingers when you hold the
cover from spinning (see Figure 47).
