10 Instructions for use V 1.5 – 10/2012
2.4 Operating the instrument
• Be very careful when handling microtome knives and disposable blades.
The cutting edge is extremely sharp and can cause severe injury!
• Never leave knives and knife holders with a knife/blade mounted lying
around!
• Never 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 skin contact with cold parts of the instrument as this can cause
frostbite!
• To make sure that the condensation water stemming from the defrost
cycles drains into the waste container and to avoid the risk of possible
contamination, ensure that the tap of the waste container (2, Fig. 22)
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 has been designed for UV disinfection.
Spray disinfection with Leica Cryofect is also possible, thanks to the spe-
cial insulation of the microtome.
(Cryofect is not available in all countries!)
Remove section waste EVERY TIME after changing the specimen!
Erst dann Desinfektion starten! Each new specimen is a potential
source of contamination.
• Do not use organic solvents or any other aggressive substances for clean-
ing and disinfection! Only use the cleaning agents and disinfectants speci-
fied in this instruction manual such as Leica Cryofect (alcohol or com-
mon disinfectants based on alcohol)!
Please contact Leica Biosystems for further details on adequate
disinfection measures.
