3-4 SECTION 3 – MAINTENANCE
9. Loosen the set screws holding the spring mandrel.
10. Turn the mandrel clockwise to decrease viscosity and counterclockwise to increase
viscosity.
11. Tighten set screws (Note the spring assembly may need to be turned
counterclockwise by hand to position the encoder against the zero stop prior to
tightening. The viscosity should read near zero)
12. Turn power off/on to zero the encoder.
13. Turn on motor switch and observe viscosity.
14. Repeat process as necessary.
