❏ Make sure the spindle is tightened securely to the viscometer coupling.

❏ Check the straightness of all other spindles; replace them if bent.

❏ Inspect viscometer coupling and spindle coupling mating areas and threads for dirt: clean threads

on spindle coupling with a 3/56-inch left-hand tap.

❏ Inspect threads for wear; if the threads are worn, the unit needs service (see Appendix H).

❏ Check to see if spindles rotate eccentrically or wobble. There is an allowable runout for

1/32-inch in each direction (1/16-inch total) when measured from the bottom of the spindle

rotating in air.

❏ Check to see if the viscometer coupling is bent; if so, the unit is in need of service.

If you are continuing to experience problems with your viscometer, follow this troubleshooting section

to help isolate the potential problem.

❏ Remove the spindle and turn the motor OFF.

❏ Gently push up on the viscometer coupling.

❏ Turn the coupling until the red pointer reaches 15-20 on the dial.

❏ Gently let go of the coupling.

❏ Watch the pointer swing freely and rest on zero.

If the pointer sticks and/or does not rest at zero, the unit most likely is in need of service. See Appendix

H for details on how to return your viscometer.
