e spindles are attached to the viscometer by screwing them onto the coupling nut on the lower sha
(see Figure II-3). Note that the spindles have a le-hand thread. e lower sha should be secured
and slightly lied with one hand while screwing the spindle to the le. e face of the spindle nut
and the matching surface on the lower sha should be smooth and clean to prevent eccentric rotation
of the spindle. Spindles can be identied by the number on the side of the spindle coupling nut.
e motor should be OFF whenever spindles are being removed or attached.
If your instrument has the EZ-Lock system, the spindles are attached as follows:
With one hand, hold the spindle, while gently raising the spring-loaded outer sleeve to its highest
position with the other hand, as shown in Figure II-4. Insert the EZ-Lock Spindle Coupling so that
the bottom of the coupling is ush with the bottom of the sha, and lower the sleeve. e sleeve
should easily slide back down to hold the spindle/coupling assembly in place for use. [Spindles
can be identied by entry code; look for the number on the side of the EZ-Lock spindle coupling.]

e motor should be OFF whenever spindles are being removed or attached.
NOTE: Keep the EZ-Lock Spindle Coupling and outer sleeve as clean as possible
and free from debris that could become lodged inside the adapter.
