Adjustable sectioning window (continued)
• First, adjust the front limit switch that is on
the front side of the instrument.
• To do so, release the knob (57.
1
) with the
blade fully retracted and move it into the de-
sired position.
• As soon as the switch is in the desired posi-
tion, tighten the knob again so that it cannot
be disengaged during sectioning.
• The rear switch can be moved only while the
instrument is in operation.
• To adjust the rear limit switch, turn the knob
(57.
2
) counterclockwise to disengage the
switch.
• Then, start the sectioning operation using
the switch for the feed movement of the Vi-
bratome.
• During the feed movement of the blade,
push the switch forward until it reaches the
desired position.
• Finally, tighten the knob to fix the switch in
place.
• You can readjust the sectioning window
whenever new specimen sizes are used.
To adjust the front and rear edge of the section-
ing window, you have to move the internal limit
switch using two rotary knobs (57), which are
on the side of the top plastic cover of the Vi-
bratome. The two rotary knobs can be adjusted
independently of one another.
