Setting Spindle Speed
Selecting one of the 8 spindle speeds available is a combination of configuring the spindle range lever and the spindle speed lever shown in Figure 66.

Figure 66. Spindle speed controls.
The spindle speed and range levers control the gear configuration in the headstock to produce the selected spindle speed. Refer to the chart below for the available spindle speeds available.
Low Range (RPM) | High Range (RPM) |
80 | 488 |
127 | 772 |
200 | 1245 |
320 | 2000 |
ALWAYS make sure the spindle is completely stopped BEFORE using the headstock control levers to make changes. If the spindle is rotating when attempting to change the spindle speed, the headstock gears will suffer damage!
Operating the lathe at spindle speeds higher than 350 RPM when the high (H) gearbox range is selected could result in gearbox damage. Always use spindle speeds of
350 RPM or lower when using the high (H) gearbox range.
Configuration Examples
Using the controls on the lathe, follow along with these two examples for setting the spindle speed to gain a better understanding of this task.
Setting Spindle Speed of 200 RPM
1.Make sure the spindle is completely stopped and the spindle lever is in the OFF (middle) position.
2.Move the spindle range lever to the right so that the arrow on top of its hub points toward the L (low) label (see the illustrated in Figure 67).
Note: If necessary, use the chuck key to rock the spindle

Spindle Speed
Lever Set to 200 RPM
Figure 67. Setting the spindle speed to 200 RPM.
3.Move the spindle speed lever so that the 200 on its hub is also pointing at the L label.
Note: You will hear a distinctive click when the spindle speed lever is in the correct position.
The lathe is now set for a spindle speed of 200 RPM.
