Take care when handling solvents!
Always wear rubber gloves and safety goggles when handling the chemicals used in this
instrument.
The reagents used can be both toxic and/or flammable.
When disposing of spent reagents, observe the applicable local regulations and the waste
disposal regulations of the company/institution in which the instrument is being operated.
Do not smoke near the stainer or the reagents.
The stainer should be operated under an extractor hood.
Once unpacked, the instrument may be transported only in an upright position.
Place the instrument on a laboratory bench and align it horizontally.
The instrument must not be placed in direct sunlight (e.g. next to a window). Avoid
impacts, bright direct light, and excessive temperature fluctuations.
Only connect the instrument to a grounded power socket. Do not interfere with the ground-
ing function by using an extension cord without a ground wire.
The instrument will automatically detect the voltage/frequency of the power source.
The installation location must be well ventilated, and must contain no sources of ignition
of any kind. The chemicals used in the Leica ST4020 are easily inflammable and hazardous
to health.
Do not operate the instrument in rooms with explosion hazard.
Condensation water may form in the instrument, if there is an extreme difference in tem-
perature between the warehouse and the installation site and if air humidity is high at the

on the instrument.
Warning labels on the instrument marked with a warning triangle indicate that the correct
operating instructions (as defined in this Instructions for Use) must be followed when op-
erating or replacing the item marked. Failure to adhere to these instructions may result in
an accident, personal injury, damage to the instrument or accessory equipment.
