Warnings – Working at the instrument
• Take care when handling microtome knives and disposable blades. The cutting edge is
extremely sharp and can cause severe injury!
• 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!
• Always clamp the specimen block BEFORE clamping the knife or blade.
• Lock the handwheel and cover the knife edge with the knife guard prior to any manipulation of
knife or specimen clamp, prior to changing the specimen block and during all work breaks!
• ALWAYS turn the handwheel clockwise; otherwise, the brake will not work properly.
• Always take appropriate safety precautions when sectioning brittle specimens! Specimen
may splinter!
• Ensure that liquids do not enter the interior of the instrument during work!
• Do not attempt to clamp, approach or orient the specimen during the retraction phase.
If a block is oriented during retraction, the block will advance by the retraction value PLUS the
selected section thickness before the next section. This involves the risk that the specimen
collides with the knife/blade!
Warnings – Cleaning and maintenance
• Only authorized and qualified service personnel may access the internal components of the
instrument for service and repair!
• Before each cleaning, switch off the instrument, disconnect the power plug, remove the knife
holder completely and clean it separately.
Always remove the knife / blade before detaching the knife holder from the instrument.
• Lock the handwheel before each cleaning!
• Do not use any solvents containing acetone or xylene for cleaning!
• Ensure that no liquids enter the interior of the instrument when cleaning!
• Do not turn the instrument on before it is completely dry!
• When using detergents please comply with the safety precautions of the manufacturer.
• Turn the instrument off with the power switch and pull the power plug, before replacing
the fuses! Only use fuses of the same specification! For fuse specifications, refer to chapter 3.3
