Figure 21. Loosening lock knob.

The belts in the headstock must be rearranged to

change spindle RPM. A chart under the pulley cover

shows the belt positions needed to make the drill press

run at the desired RPM. For example, the pulley ratio

shown in

Figure 20 indicates belt positioning to get 569

RPM at the spindle.

Changing Spindle RPM

Never operate drill press with pulley cover in the

open position. Your hand may become trapped in the

belt and serious personal injury will occur.
