Warnings – Safety instructions / warning labels attached to the instrument
• Safety instruction labels on the instrument marked with a warning triangle indicate that the
correct operating instructions (as described in this manual) must be followed when operating
or replacing the instrument component bearing the label.
Failure to adhere to these instructions may result in an accident, personal injury, damage to
the instrument or accessory equipment.
Warnings – Transport and installation
• Once removed from the crate, the instrument may only be transported in an upright position.
• Never lift the instrument by the handwheels or the cassette clamp. Always remove the section
waste tray before transporting the instrument.
• Caution! The voltage selector has been preset at the factory.
Before connecting the instrument to the line voltage, please check that this setting complies
with the local power requirements of your laboratory.
The power cable inlet is closed with an adhesive tape that indicates the actual voltage setting
of the instrument upon arrival. Severe damage can be caused to the instrument if the voltage
selector is set to an incorrect voltage!
• When changing the voltage selector setting, ensure that the instrument is not connected to the
line voltage!
• Connect the instrument to a grounded power socket only using one of the power cables provided.
• Do not operate in rooms with explosion hazard.
• Exposure to extreme temperature changes between storage and installation locations and

Leica RM2245
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!
