PART 2 OPERATING INSTRUCTIONS
2-1 SETTING UP THE
MICROTOME
Unpack the microtome and remove the wrapping.
On the lower side of the instrument towards the
front and rear longitudinal axis, there are recessed
grips to lift or carry the microtome. Do not
transport the instrument on the handle of the
handwheel!
Sectioning can be influenced by nearby instruments
which generate vibrations. For this reason, the
microtome should be placed on a stable and
vibration free table. To move the unit on the table,
lift the base slightly at the front end only and slide
it.
NOTE! Remove the section waste tray to move or
carry the instrument. The section waste tray can
be pulled out of its proper position.
2-2 INITIAL TURN-ON
CAUTION! Before turning on the instrument for
the first time, please check if the power
requirements indicated on the type plate correspond
to the power supply voltage being used.
The operating panel (fig. 4.1), which is separately
packed, can be attached to the instrument or used
freestanding. Firstly, connect the operating panel
with the instrument. A 37-lead control cable (fig.
2.1) is fixed on the back of the instrument. Connect
this cable with the connector at the back of the
operating panel.
Should the operating panel be attached to the
instrument, push the 37-lead connector through the
corresponding hole (fig. 2.2) on the back of the
microtome. Turn the connector 90° and push it
through the hole on the front of the instrument.
Plug the connector into the operating panel. Fasten
the cable on the panel with the two screws. To
clear away the cable, insert it into the
corresponding holders (fig. 2.3) on the back of the
microtome.
As above-mentioned, the operating panel can be
used freestanding. It can be placed on the left as
well as on the right side of the microtome. For this,
the operating knobs (fig. 4.3 and 4.4) can easily be
removed and placed on the other side of the
operating panel.

Connect the 5-lead plug of the foot pedal cable into
the outlet (fig. 2.6) and tighten the swivel nut.
NOTE! If the foot pedal is not connected, there is
the operating mode emergency stop (see part 2-6-
7). This way, the handwheel brake is activated and
the cutting drive motor cannot be started. Always
connect the foot pedal!
Connect the power cord to the power socket (fig.
2.4) on the back of the instrument. Turn on the
power switch (fig. 2.5).
Then, the specimen holder moves to the rear end
position. This movement is always carried out
when the instrument is turned on. This way, the
instrument is calibrated.
The insert for the two fuses is placed beside the
power switch. The fuse for the motor supply is
placed on the left side of the mains plug unit.
(See part 5, exchange of fuses).
The terms shown on the display are available in
English, German and French. If desired, the user
can change the language. (see part 2-9, selecting
the indicated language).
