OPERATIONS
Changing Speeds
To change speeds, the belt in the headstock must be repositioned. A chart on the pulley cover shows the belt positions needed to make the lathe run at the desired speed.
To change speeds, do these steps:
1.Loosen the lock handle, remove the belt cover, and open the access plate (Figure 6).
2.Loosen the belt tension lock knob, and move the belt tension lever up to reduce tension on the belt.
3.Locate the desired speed on the speed chart on the belt cover, and move the belt to the desired grooves on the motor and spindle pulleys.
For Example: As indicated in the speed chart, pulley ratio B creates 1270 RPM (Figure 7).
4.Move the belt tension lever down, tighten the lock knob, and reinstall the access plate and belt cover.
Adjusting Tailstock
The tailstock is equipped with a
To position the tailstock along the bed, do these steps:
1.Loosen the release lever and move the tailstock to the desired position (Figure 8).
2.
—If the release lever will not lock the tailstock down onto the bed (either too loose or too tight), loosen or tighten the hex nut (located on the underside of the tailstock) in small increments as needed to achieve the proper clamping pressure.
