Brookfield DV1 Viscometer - Manual (Page 16)

The spindles are attached to the viscometer by screwing them onto the coupling nut on the lower shaft
(see Figure II-3). Note that the spindles have a left-hand thread. The lower shaft should be secured
and slightly lifted with one hand while screwing the spindle to the left. The face of the spindle nut
and the matching surface on the lower shaft should be smooth and clean to prevent eccentric rotation
of the spindle. Spindles can be identified by the number on the side of the spindle coupling nut.
The 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 flush with the bottom of the shaft, and lower the sleeve. The sleeve
should easily slide back down to hold the spindle/coupling assembly in place for use. [Spindles
can be identified by entry code; look for the number on the side of the EZ-Lock spindle coupling.]

The 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.
