Spindle Speeds

NOTICE

NEVER move levers while the lathe is run- ning, and NEVER force any lever when shifting.

The spindle speed or RPM is controlled by the speed control levers (Figure 17). Use the chart in Figure 18, to find the best spindle speed required for your task.

Figure 17. Spindle control levers.

The chart below shows the various combinations of knob positions for achieving a desired speed.

Example:

To select a spindle speed of 600 RPM, move the alpha lever until the indicator arrow points to C. Move the numeric lever so it points to 3.
