Safety instructions — working with the instrument
• Always lock the handwheel before 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!
• When using cleaners, please comply with the safety instructions of the manufacturer
and the laboratory safety regulations!
Hazards — servicing and cleaning
• Prior to manipulating the knife and specimen, or changing the specimen or knife, and
during breaks, always lock the handwheel and cover the cutting edge with the knife
guard.
• ALWAYS turn the handwheel clockwise; otherwise, the brake will not work properly.
• Always wear safety goggles when sectioning brittle specimens. Specimens may splin-
ter!
• Specimen blocks must NOT be oriented during the retraction phase. If a block is oriented
during retraction, the block will advance by the retraction value PLUS the selected sec-
tion thickness before the next section. This may cause damage to both specimen and
knife!
• 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.
