Cleaning the instrument
Warning
• Always remove the knife or blade before detaching the knife/blade holder from the instrument!
• Always put the knives back into the knife case when not in use!
• Never place a knife anywhere with the cutting edge facing upwards and never try to catch a falling
knife!
• When using cleaning agents, observe the manufacturer's safety instructions and the laboratory
regulations valid in the country of use.
• When cleaning the outer surfaces, do not use xylene, scouring powders or solvents containing
acetone or xylene. Xylene or acetone will damage the finished surfaces!
• Ensure that liquids do not enter the interior of the instrument during cleaning!
Before each cleaning carry out the following preparatory steps:
• Move the specimen clamp to the lower end position and activate the handwheel lock.
• Remove the blade from the blade holder and insert it in the receptacle at the bottom of the dispenser,
or remove the knife from the knife holder and put it back in the knife case.
• Remove knife holder base and knife holder for cleaning.
• Remove the specimen from the specimen clamp.
• Take out the waste tray and remove the section waste with a dry brush.
• Remove specimen clamp and clean separately.
Clean the instrument and outer surfaces
• If necessary, the varnished outside surfaces can be cleaned with a mild, commercial household
cleaner or soapy water and then wiped with a moist cloth.
• To remove paraffin residue, xylene substitutes, e.g. Roth Histol (Roth, Karlsruhe), Tissue Clear
(Medite), Histo Solve (Shandon), paraffin oil or paraffin removers, e.g. Paragard (Polysciences) can
be used.
• For treating varnished surfaces, a commercially available varnish cleanser is recommended.
• The instrument must be completely dry before it can be used again.
• Anodized parts (e.g. the specimen clamps) can also be cleaned with solvents.
