Safety instructions for handling the instrument
Sectioning
• Take care when handling disposable
blades.
The cutting edge is extremely sharp and
can cause severe injury!
• Never leave the knife holder with a blade
mounted lying around!
• Dispose of used blades by inserting them
into the receptacle provided at the bottom
of the disposable blade dispenser!
• Always clamp the specimen before the
blade!
• Take care when removing the section - the
cutting edge is exposed!
• Prior to manipulating the knife holder and
specimen, or changing the specimen or
blade, and during breaks, always lock the
handwheel and cover the cutting edge
with the anti-roll guide!
• Avoid extended skin contact with cold
parts of the instrument as this can cause
frostbite!
Cleaning and disinfection
• Do not use organic solvents or any other
aggressive substances for cleaning and
disinfection!
We strongly recommend the use of Leica
Cryofect disinfectant spray!
Only use alcohol or common disinfectants
based on alcohol!
• For spray disinfection follow the instruc-
tions for use supplied with the disinfec-
tant!
• Do not use external heaters for drying the
cryochamber. This can cause damage to
the slot cover!
Removal of the microtome
• Before removing the microtome, turn the
instrument off with the mains switch!
• Wear appropriate protective gloves to re-
move the cold microtome from the cryo-
chamber! Risk of frost bite!
Or wait until the microtome has reached
room temperature.
• The microtome must be completely dry be-
fore reinstallation. Humidity inside will
condense and freeze in the cold cryostat
and thus may cause malfunctions or dam-
age.
Maintenance
• Only qualified and authorized service per-
sonnel may access the internal compo-
nents of the instrument for service and re-
pair.
Fuse replacement
• Only use a fuse of the same specification!
For the required value, please refer to
Chapter 4. 'Technical data' or to the fuse
specification label at the rear of the instru-
ment.
