Preparing for inspection and maintenance
9.3.1
Procuring spare parts
The original components of the product were also certified
by the manufacturer as part of the declaration of conformity.
If you use other, non-certified or unauthorised parts during
maintenance or repair work, this may void the conformity of
the product and it will therefore no longer comply with the
applicable standards.
We strongly recommend that you use original spare parts
from the manufacturer as this guarantees fault-free and safe
operation of the product. To receive information about the
available original spare parts, contact the contact address
provided on the reverse of these instructions.
▶
If you require spare parts for maintenance or repair
work, use only the spare parts that are permitted for the
product.
9.3.2
General inspection and maintenance
information
Inspection
The inspection is intended to determine the actual condition
of the respective product and compare it with the target con-
dition. This is done by measuring, checking and observing.
Maintenance
Maintenance is required in order to eliminate any deviations
between the actual condition and the target condition. This is
normally done by cleaning, setting and, if necessary, repla-
cing individual components that are subject to wear.
9.3.3
Checking maintenance messages
