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 mains power, please check that this setting complies with the local power requirements of your laboratory.

The mains 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 mains power!

•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 high air humidity may cause condensation inside the instrument. If this is the case, wait at least two hours before switching on the instrument. Failure to comply with this may cause damage to the instrument.

•The protective devices on both instrument and accessories must neither be removed nor modified.

Personal safety precautions

•When working with microtomes, personal safety precautions must always be taken. It is man- datory to wear work safety shoes, safety gloves, a mask and safety goggles.
