SECTION 5: CONTROLS

Spindle Speeds

The rotating speed of the headstock is controlled by the positioning of the belts on the pulleys. See Figure 7. These are accessed by removing the cover on the end of the headstock. Refer to the chart at the end of this manual or the plate on the headstock (Figure 8) to determine which belt combinations produce what speeds. The speed settings available on this machine are 130, 300, 400, 600, 1000 and 2000 RPM.

This belt tensioning lever on the top of the head- stock loosens the drive belt to enable the opera- tor to change speeds. See Figure 9. The tension release lever can also be used as a clutch while the machine is in operation.

NEVER reach across a rotating chuck or plate. The use of the Belt Tension Release Lever as a clutch should be restricted to those times when starting a heavier part turning and then at very low speed.
