5 Operation
Checking the setting
The new setting must be checked whenever a change has
been made in the unbalance compensation.
The tool must be removed from the unit. The vortex movement
of the unit must not be switched ON while the tool is still in
the drive. This could cause damage to the unit and lead to
personal injuries.
Fasten the rack and the vacuum connection for which the
new settings apply, with the glasses in them, on the platform.
Start the vortex movement slow and slowly increase the
speed. This lets you shut off the vortex movement in time if
the settings made are incorrect.
Set the desired rotational speed (according to the recommen-
ded values for the various racks). If the unbalance compen-
sation has been correctly set, the unit should attain the pre-set
shaking speed without any strong vibrations of its own.If this
not the case, the shaking movement must be terminated in
order to check if balancing compensation is required and in
any case to establish a fine state of balanced. This is achieved
by alternating adjustments to and assessments of the settings.
The unbalance compen sa tion needs to be readjusted. The
compensation can be fine-tuned by watching movable ob-
jects close to the unit (e.g., loose cables, surface of liquids).

volume and solvent)
