Setting Spindle Speed

The chart below explains how to position the spindle range and speed levers to set the desired spindle speed.

210 RPM	L	2
345 RPM	L	3

Change spindle speed ONLY when the spindle is completely stopped. Otherwise, machine damage could occur.

With the spindle completely stopped, position the spindle range and speed levers (see Figure 27) to set the spindle speed.

Note: If the levers will not move to the desired position, rotate the spindle by hand while applying pressure on the lever. When the gear teeth align, the lever will move into place.
