Changing Speeds

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.

Figure 20. Loosening lock knob (both sides).

3.Rotate the belt tension lever counterclock- wise, as shown in Figure 21, to take tension off the V-belts.

4.Locate the desired speed on the speed chart under the belt cover and move the V-belts to the desired V-grooves on the motor, idler, and spindle pulleys.

For Example: As indicated in the speed chart (Figure 22), a belt combination of A-2creates 540 RPM.

Note: Both belts may have to be removed before certain speed changes can be made.
