2.8 Fitting the spindle
Note:
This operation must be done very carefully to
ensure that the spindle is not bent and the motor drive
coupling or internal components are not damaged.
1. Consult “Spindle selection tables” on page 19 to identify
the correct spindle to use; the spindle type is stamped
into the spindle coupling.
2. Check that the threads and connecting surfaces of the
spindle and the motor drive coupling are clean.
3. If the spindle is of a disc type, it should be submerged
carefully in the sample to avoid bubbles forming under its
lower surface.
4. Grasp the motor drive coupling with one hand, raise it
slightly and then screw the spindle onto the coupling
gently.
The screw has a left-hand thread
.
5. Adjust the height of the Viscometer head until the spindle
is immersed in the sample up to the immersion point,
indicated by a groove on the spindle. T
ake care to avoid
knocking the sample container against the spindle during
this operation as this may damage the spindle and motor
drive coupling
.
