depth. The scale on this depth stop can be
calibrated if it ever becomes incorrect.
To calibrate the depth stop
:
1. Loosen the calibration nut shown in Figure
29.

2. Set the depth nut to zero, and secure it with
the jam nut.
3. Tighten the calibration nut to hold the depth
stop in position.
4. Move the depth nut and jam nut to a non-zero
measurement to allow the spindle to move.
5. Test the depth stop by measuring how far the
spindle actually moves with respect to where
you set the depth stop
.
Feed Shaft Spring
Tension
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 30 for
spring lock cover identification
).
