6.2 Maintenance Instructions
The instrument is basically maintenance-free.
To ensure trouble-free operation of the instrument over a long period of time, the following is
recommended:
• Have the instrument checked at least once a year by a qualified service technician authorized
by Leica.
• Enter into a service contract at the end of the warranty period. For more information, please
contact your local Leica technical service center.
Only authorized and qualified Leica service personnel may repair the instrument and
access the instrument’s internal components.
For your safety, never attempt to repair the instrument yourself.
Unauthorized repairs will render any claims under the warranty null and void. See
also the section on "Warranty" in
Chap. 9
on this matter.
Cleaning the instrument
(continued)
Caution!
The stations must not be exposed to elevated temperatures (e.g. in industrial dish-
washers, which operate at a temperature of +85 °C), because the heat can deform the
stations!
The reagent and rinsing water containers must be cleaned regularly in order to achieve consis-
tently good staining results.
They can also be cleaned in the dishwasher at a max. temperature of +65 °C. Any standard
cleaning agent for laboratory dishwashers may be used.
