3-5 CUTTING MOVEMENT AND
RETRACTION
The cutting movement of the microtome is
generated by turning the hand wheel.
• To start the cutting movement of the
microtome, turn the hand wheel.
• As the specimen moves down, sectioning is
carried out (cutting movement, fig. 15.2).
• Continue turning the hand wheel to bring the
specimen back up (fig. 15.4).
• To protect the knife and specimen during
return travel, the specimen is retracted (R).
• The yellow LED RETRACTION (fig. 16.1) lights
up. If desired, the function <retraction> can be
turned off.
