To properly adjust the potentiometer, measure the

potentiometer’s maximum ohm value using an

ohmmeter then divide the max. value by two to

find the center (neutral) position.

Example: Maximum value 5.0K ohms



2.5K ohms (+/- 10%) center position.

With the machine’s control grips at the neutral

position, rotate the body of the potentiometer up

or down until the reading on the ohmmeter is at

the center (neutral) position. Tighten nut.
