abled in semiautomatic mode:
• Setting cutting window edges
• Selecting the continuous stroke

for the automatic feed (AUTO

In automatic mode, the selected
section thickness feed (AUTO
FEED) is carried out along the 1st

prevent the specimen surface and
the blade from coming into contact
while the blade is being retracted,
the specimen is lowered by the
desired retraction value along the
2nd cutting window edge after
each complete cut.
The following functions keys be-
come enabled again in automatic
mode:
• Cutting window edges that have
already been set
