Inspection and maintenance
8.1
Observing inspection and maintenance
intervals
Proper regular inspections (once a year) and maintenance
(depending on the result of the inspection, but at least once
every two years) combined with the exclusive use of genuine
spare parts are decisive factors in ensuring smooth opera-
tion and long working life for the product.
We recommend taking out an inspection or maintenance
contract.
Inspection
The inspection is intended to determine the actual condition
of a product and compare it with the target condition. This is
done by measuring, checking and observing.
Maintenance
Maintenance is required in order to eliminate any deviations
of the actual condition from the target condition. This is nor-
mally done by cleaning, setting and, if necessary, replacing
individual components that are subject to wear.

turer, their responsible customer service depart-
ment or suitably qualified persons.
