M1102/M1103 16-Speed Drill Press

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.

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.

To change spindle RPM, do these steps:

1.DISCONNECT THE DRILL PRESS FROM POWER!

2.Loosen the belt tension lock knob (shown in Figure 21) on the right side of the headstock, to take ten- sion off of the V-belts and allow the motor to move freely.

3.Locate the desired speed on the Drill, Cutter, and Hole Saw Suggested RPM Chart starting on Page 23.

4.Move the V-belts to the desired V-grooves on the motor, idler, and spindle pulleys.

5.Pivot the motor toward the back of the headstock and tighten the lock knob once the desired V-belt tension is achieved.

6.Close the cover before plugging in the machine.
