10 Instructions for use V 2.6 – 10/2012
• Never leave knives and knife holders with a knife/blade mounted lying
around!
• Do not place a knife on a table with the cutting edge facing upward!
• Never try to catch a falling knife!
• Always clamp the specimen before the knife!
• Prior to manipulating the knife and specimen, or changing the specimen
or knife, and during breaks, always lock the handwheel and cover the
cutting edge with the knife guard!
• Avoid contact with cold parts of the instrument as this can cause frost-
bite!
• To make sure that the condensation water stemming from the defrost
cycles drains into the waste container and to avoid the risk of possible
contaminations, ensure that the tap of the waste container (2, Fig. 31.1) is
open when operating the instrument. Only shut the tap when draining
the waste container!
2.5 Cleaning and disinfection
• It is not necessary to remove the microtome for routinely disinfecting the
cryochamber.
The instrument is appropriate for spray disinfection with Leica Cryofect!
• Do not use organic solvents or any other aggressive substances for clean-
ing and disinfection!
Only use the cleaning agents and disinfectants specified in this instruc-
tion manual such as Leica Cryofect (alcohol or common disinfectants
based on alcohol)!
2.6 Removal of the microtome
• Prior to removing the microtome, turn the instrument off with the mains
switch and pull the mains plug.
• Prior to removing the microtome, bring the specimen head to the lower
position with the handwheel.
Otherwise the specimen head would rapidly fall down and might injure
the operator‘s hands, when taking out the microtome.
• Wear appropriate protective gloves to take the cold microtome out of
the cryochamber.
