Check the stability of the specimen head each time it clicks back
into place. This can prevent it from becoming difficult to set the
zero position.
Before using them for the first time, degrease new knives using
acetone or alcohol.
• Approach the specimen with the knife or blade holder:
• To do so, open the clamping lever of the base, approach the speci-
men and close the lever again.
• Open the lever of the orientation. Orient the specimen (move it into a
favorable position relative to the knife/blade) and close the lever again.
• Approach the knife or blade holder using the coarse feed buttons and
gentle movements of the handwheel.
If the sections are cracked, the specimen head temperature is too
cold. Set a warmer temperature.
If the sections smear, the specimen head temperature is too warm.
Set a colder temperature.
• Remove the silicone stopper from the filter cover (and keep it in a safe
place).
• Insert the extraction hose with the black adapter.
• Fold the anti-roll guide to the side and fasten the extraction nozzle to the
pressure plate (using 4 magnets on the rear side of the nozzle) – see mark
(Fig. 56a).
• Fold the anti-roll guide back into position.
