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.

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).
