8.2 Maintenance
Only authorized Leica technical service engineers may open the in-
strument for maintenance and repair work.
Exception: Changing the activated carbon filter - this is the only
maintenance task to be carried out by the user!
For your own safety, never try to carry out any repairs yourself!
Any unauthorized repair, whether carried out by the user or any third
party not authorized by Leica will void the guarantee (see also Chap-
ter 9.1 ‘Warranty’).
The Leica ST4040 linear stainer is virtually maintenance-free in operation.
However, to ensure a smooth operation of the instrument over many
years, we recommend the following:
• Have the instrument inspected once per year by a qualified service en-
gineer 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.
• Exchange the activated carbon filter regularly and dispose of it ac-
cording to the applicable laboratory rules in your country.
