sary move the handwheel slightly back and forth, until you feel that the
locking mechanism engages.
To unlock the handwheel, push the metal pin (1) out of the recess at the
handwheel, towards the cryostat housing.
Prior to manipulating knife and specimen, when changing the
specimen or during breaks, always lock the handwheel and
cover the cutting edge with the knife guard!
