7.2 Maintenance of the stand
Dust can be removed with a brush. In case the stand or table is really dirty the surface can be
cleaned with a non-aggressive cleaning product.
All moving parts like the height adjustment or the coaxial course and fine adjustment contain ball
bearings that are not dust sensitive. With a drop of sewing-machine oil the bearing can be
lubricated.
7.3 Changing the batteries of the BioBlue
Caution:
Always remove the power cable from the mains supply !
Remove the smal lid out of the bottom cover of the microscope.
Place the batteries and put the lid back into its place.
7.4 Tension control setting
Between the right-handed coarse adjustment knob and the microscope stand there is a ring for
the tension control setting. By means of turning it clock- or counter clockwise the tension of the
coarse adjustment knobs can be adjusted.
