Instrument and outside surfaces
If necessary, the varnished outside surfaces of the control panels can be
cleaned with a mild commercial household cleaner or soap water and then
be wiped with a moist cloth.
To remove paraffin residue, xylene substitutes, paraffin oil, or paraffin remov-
ers such as "Para Gard" (Polysciences) can be used.
The instrument must be completely dry before it can be used again.
Never place blade or knife holders with/
without base close to the edge of the
table to prevent them from falling down.
Always wipe the knife from the back of the knife to the cutting edge. NEVER wipe in the oppo-
site direction - risk of injury!
Before each cleaning, carry out the following preparatory steps: Always remove the
knife / blade before detaching the knife 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. Acetone or xylene will damage the finished surfaces!
Ensure that liquids do not enter the interior of the instrument during cleaning!
