Warnings – working at the instrument
During operation, metal surfaces and components inside the cryochamber can reach tempera-
tures from as low as -196°C up to as hot as +110°C!
Touching these extremely cold or hot parts can cause severe injury!
For that reason, for any type of manipulations inside the cryochamber you may use only the
special tools which come as part of the standard delivery and the use of which is described in
detail in the present manual.
Transfer of frozen specimens may also only be done by means of the corresponding special
tools.
Always attach the specimen holder before inserting the knife holder!
The light has to be on as long as the knife is inside the cryochamber!
Exercise extreme caution when handling knives! The cutting edges are extremely sharp and
can cause severe injury!
Never try to catch a falling knife!
The knife may only be inserted into the knife holder shortly before sectioning and must be re-
moved from the knife holder directly afterwards!
To insert the knife holder into the cryochamber, always use the corresponding manipulator
(part of standard delivery)!
The knife edge is exposed! Risk of injury!
Cleaning
Do not use acetone or xylene to clean the lacquered surfaces of the instrument.
