The Operating Manual is an important part of the product, and must be
read carefully prior to startup and use and must always be kept near the
instrument.
If additional requirements on accident prevention and environmental protection apply in the country of operation, these Instructions for Use must
be supplemented by appropriate instructions to ensure compliance with

2.1 General safety notes
These instruments have been built and tested in accordance with the safety
regulations for electrical measuring, control, regulating and laboratory
devices.
In order to maintain this condition and to ensure safe operation, the user
must follow the instructions and warnings contained in this operating manual.
2.2 Warnings

The current EC Declarations of Conformity can be found on the Internet:
www.LeicaBiosystems.com
The safety devices installed in this instrument by the manufacturer only
constitute the basis for accident prevention. Operating the instrument safely
is, above all, the responsibility of the owner, as well as the designated personnel who operate, service or clean the instrument.
To ensure trouble-free operation of the instrument, make sure to comply
with the following instructions and warnings.
Instructions for Use V 1.4 RevC – 09/2013
• Extremely sharp blades pose risk of injury when touched!
• Fresh tissue poses risk of infection!
• Fire hazard from uncovered magnifier! Cover the magnifier during work breaks!
Proper handling
Always be exceptionally careful when handling the blades!
Do not leave open blades lying around after removal.
Always make sure to handle the blade in a way that will not cause you injury.
All appropriate safety precautions must be met to avoid the risk of infection.
Wearing safety gloves, a mask and safety goggles—in accordance with the "Working with Sub-
stances that Pose a Health Risk" guidelines—is absolutely mandatory.
The instrument may be opened by authorized service personnel only.
Always disconnect the power plug before opening the instrument.
Always switch off the instrument using the power switch and disconnect the power plug before
replacing the fuse. The use of fuses other than those installed at the factory is not permitted.
2.3 Transport, unpacking and setting up
2. Safety
The instrument must be set up so that the main power switch on its right side (item 7 in Fig. 14) is
easily accessible at any time.
Because the weight of the instrument is approx. 56 kg, carrying the instrument requires 2 persons
(1 carrying handle per person).

The Leica VT1200 is a semiautomatic microtome with a vibrating blade. Before each cut, a manual feed to the desired section thickness must be carried out using the setting dial for section
thickness. The VT1200 does not include an automatic specimen retraction; however, retraction
can be performed manually.

The Leica VT1200 S is a fully automatic microtome with vibrating blade. It can be operated in automatic as well as
semiautomatic sectioning mode.
In semiautomatic sectioning mode, a manual feed to the desired section thickness must be carried out before
each cut. There is no automatic specimen retraction in this mode; however, retraction can be performed manually.
In automatic mode, an automatic feed (AUTO FEED) to the selected section thickness is carried out before each
cut, and the specimen is lowered to the desired retraction value after each cut to prevent the specimen surface
and the blade from coming into contact while the blade is being retracted.

men into the lowest

4.2 Packing and setting up the instrument
Ensure that the instrument is standing on a work surface that is as free
of vibrations as possible.
Before each transport, the handles must be screwed onto the instrument using the
provided screws (see Fig. 13). Check to ensure that the handles are firmly in place
and will hold reliably!
Packing the instrument
1. Have 2 people grab the instrument by the transport handles (1), place it
