16.6.10. Speed Change

a. Disconnect Lathe from power source.

b. To change speed ranges, pull open the access door on

the headstock.

c. Loosen the pivot lock handle (A, Figure 22) and lift up

the tension handle (B, Figure 22) to raise the motor.

Tighten the pivot lock handle (A, Figure 22) to hold the

motor in the raised position. 4. There should be

sufficient slack in the belt to reposition it to the other

steps on the sheaves. The label on the access door

shows the required belt position.

d. Loosen the pivot lock handle (A, Figure 22) and lower

the motor to tension the belt. Be sure that the Poly-V

grooves of the belt seat properly in the corresponding

groove of the sheave. Do not overtension; a very light

pressure on the tension handle (B, Figure 25) is

adequate to prevent belt slippage.

e. Tighten the pivot lock handle (A, Figure 22).
