Leica Biosystems CM1850 UV - Manual (Page 7)

7 Leica CM1850 UV – Cryostat
2.1 Safety features
The instrument incorporates the following safety features: safety handwheel
and knife guards on the knife holders.
To prevent adverse health effects from UV radiation, the UV disin-
fection cycle can be started only after the sliding window has
been properly closed. Closing the window activates the corre-
sponding safety features.
The consistent use of these safety features and strict observation of the
warnings and cautions in this manual, will safeguard the operator from ac-
cidents and/or personal injury to a great extent.
2.1.1 Locking the handwheel
Prior to manipulating the knife and specimen, or changing the
specimen or knife, and during breaks, always lock the handwheel!
For locking the handwheel rotate the handle until it is in the upper position.
Push the locking pin (1) into the recess at the handwheel. The locking posi-
tion is marked by a black dot (2). If necessary, move the handwheel slightly
forth and back until the locking mechanism engages.
To unlock, push the locking pin (1) to the left from the recess at the handwheel.
Only rotate the handwheel when the refrigeration system is on
and the cryochamber is cold.
