11 Leica CM1850 – Cryostat
Extended skin contact with cold parts of the instrument may cause frost
bite!
• The microtome must be entirely dry before reinstallation. Humidity inside
will condense and freeze in the cold cryostat and thus cause malfunc-
tions or damage.
• Do not use external heaters for drying the cryochamber. This can cause
damage to the cooling system!
• All components removed from the cryostat must be carefully dried be-
fore they are replaced in the cryochamber
2.7 Maintenance
Replacement of the fuses
• Turn the instrument off with the automatic mains fuse and pull the mains
plug, before replacing the fuses.
• Only use fuses of the same specification! For the required values, please
refer to Chapter 3 ‘Technical data‘.
The use of fuses other than specified by the manufacturer may cause
severe damage to the instrument!
Replacement of the lamp
• Turn the instrument off with the automatic mains fuse and pull the mains
plug, before replacing the lamp.
• If the lamp is broken, it must be replaced by the technical service, as the
replacement involves a high risk of injury.
