Height adjustment block in horizontal position
4 Loosen the locking collar on each shaft.
5 Gently slide each shaft halfway up through each spindle. If shafts are hard to to slide, a
very thin film of vacuum grease applied on the top end of the shaft will allow it to slide
smoothly.
6 Install and secure (finger tight) the paddle blades.
7 Lower the drive head onto the height adjustment block and turn the drive lift knob to lock
position.
8 With vessels in place, gently push down each shaft until the paddle blade touches the
bottom of each vessel.
9 Lock each shaft collar using 5/64 inch hex wrench. Do not over-tighten the set screws on
the shaft collars and avoid putting any weight on the drive head when performing this
step.
For better height adjustment reproducibility, it is recommended to keep vessels in
the same position after emptying and washing.
