Figure 21. Using the belt tension lever.

The belts in the head of the drill press must be
rearranged to change speeds. A chart under the
belt cover shows the belt positions needed to
make the drill press run at the desired speed.

To change speeds:

1. UNPLUG THE DRILL PRESS!

2. Loosen the belt tension lock knobs (Figure

20), on both sides of the headstock, so the
motor is free to move.

3. Rotate the belt tension lever counterclock-

wise, as shown in

Figure 21, to take tension

off the V-belts.
