Cleaning steps:
• Use a brush to remove all loose sectioning waste from the instrument
and dispose of.
• Pull out the sectioning waste trays (1) located below the extendible car-
rying handles at the front and rear of the instrument.
The microtome housing consists of several plastic panels.
The front and rear panel are spring-held and can be removed eas-
ily when necessary.
The waste trays, located below the extendible carrying handles at
the front and rear of the housing, gather the sectioning waste
which is transferred to the trays via the cover ribbon.
The trays must be emptied before they are filled to the brim - other-
wise the cover ribbon could be damaged or get dirty.
Check the waste trays daily and empty as required.
• Remove the knife holder. Clean the bearing surfaces of the bearing
blocks and the knife holder itself.
• Remove the upper front panel (2).
• Switch the instrument on.
• With a brush and/or a cleaning cloth slightly moistened with laboratory
cleaner, clean the cover ribbon in the area where it is supported by the
deflection roller:
Move the ribbon step by step (via buttons 56 - 59, see area 5.2, chapter
5.4.14) until the entire ribbon has been cleaned.
If possible, clean the cover ribbon only in the area where it is sup-
ported from below by the deflection roller.
Only very light pressure may be applied to the horizontal part of the
ribbon - otherwise it might slip out of the lateral guides.
Should that happen, immediately re-insert the ribbon into the
guide(s) to prevent sectioning waste from entering the interior of
the instrument!
• Put the upper front panel (2) back in place.
• If required, wipe down the housing surfaces with a cleaning cloth slightly
moistened with laboratory cleaner.
