Radial Drill Press

-31-

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 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).
