Hazards – servicing and cleaning
Safety instructions – working with the instrument
• Take care when handling microtome knives and disposable blades. The cutting edge is
extremely sharp and can cause serious injuries!
• 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 manipula-
tion 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! Specimens
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 may cause damage to both speci-
men and knife!
• The handle of the handwheel must always be centered while in motorized sectioning mode.
Do not touch the handwheel while it is running – there is a danger of injury from the hand-
wheel lock.
• Prior to sectioning, check that the specimen is securely clamped in the specimen clamp –
failure to observe this poses the risk of damaging the specimen.
• 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 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 liquids do not enter the interior of the instrument during 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 disconnect the power plug before re-
placing the fuses! Only use fuses of the same specification! For fuse specifications, refer to
Chapter 3.3 – "Technical Data" .
