Spindle speed
Using the correct spindle speed is important for safe and satisfactory results, as well as maximizing tool life.
To set the spindle speed for your operation, you will need to:
(1) Determine the best spindle speed for the cutting task, and (2) configure the lathe controls to produce the required
spindle speed.
To change the spindle speed:
1. Make sure the spindle is turned OFF and it has come to
complete stop.
2. Move the spindle speed range lever to the range that
covers your calculated spindle speed. When the lever to the L
position, the speed range is 70-440 RPM, when the lever to
the H position, the speed range is 350-2000 RPM.
Note:
To shift the spindle speed range lever, you may need to
apply pressure to the lever and slightly rotate the spindle by
hand.
Warning!
Make sure the variable speed control knob is turned all
the way to the left (counterclockwise) before turning the
lathe ON, or it may start up at a dangerously high rate of
speed.

4. Turn the spindle ON and slowly turn the variable speed control knob to carefully adjust the spindle speed (show on
the spindle speed display) to your calculated spindle speed.
