Figure 49. Speed change chart.
To change the belt position on the pulleys:
1.Disconnect the lathe/mill from the power source!
2.Remove the drive belt cover.
3.Loosen the bolt on the tensioner bracket (shown in Figure 50) with a 19mm wrench.

4.Move the pulley bracket away from the belt.
5.Position the belt into the pulley sheaves that dictate the speed required for your operation.
6.Move the pulley bracket into the belt and ten- sion it until there is about 1⁄2" deflection on the side of the belt that is opposite of where the tensioner is making contact. Figure 51 shows how to check for proper tension by using a ruler and your thumb. Note—only moderate pressure is needed to check belt tension!

7.Replace the drive belt cover.
Some threading operations may damage the lead screw if performed at high speeds. Always use the slowest speed possible for your particular operation!
