Drill Press Speeds

The speed of the drill press spindle is controlled by 2 groups of belts and pulleys. The belt posi- tions on the end of the lathe control one speed range. See Figure 23. The belts and pulleys above the drill press control the other range. See Figure 24.

Disconnect the power before changing speeds or making adjustments to this machine. Failure to do this may result in serious personal injury.

Unplug the Lathe/Mill! Before using the drill press, the hub at the end of the lathe spindle must be adjusted to the “in” position. See Figure

25.To ease engagement of this hub, slowly rotate the drill spindle by hand while applying pressure to the hub.

The chart also shows the various combinations of belt positions for achieving a desired speed.

Example:

To select a spindle speed of 310 R.P.M., start by moving the belts at the end of the lathe. Move the lower belt to the “B” position. Move the upper belt to the “F” position. Follow the belt changing pro- cedures in the section titled Lathe Speeds.

Next, move the belt located above the drill press to the “L-H” position.
