Page 86 Power Equipment Usage Manual (Rev. 5/10)
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).
