obtain consistent contact with the resistor.
e. Loosen the three adjustment screws on the underside of the poten-
tiometer assembly and rotate the spring adjuster until the spring
rests at a relaxed state.
f.
Ensure that the contact arm aligns with the contact strip and tighten
the three set screws.

rub the potentiometer housing.
h. Replace the shaft-bearing retainer and calibrate the potentiometer.
