11.2 Observing inspection and maintenance
intervals
Danger!
Risk of damage and personal injury as a
result of neglected and improper inspec-
tion and maintenance.
Inspection and maintenance must only be
performed by a competent person.
▶ Carry out the inspection and maintenance
work described on a regular basis and to a
professional standard.
Regular inspection/maintenance and exclusive use of ori-
ginal spare parts are absolutely essential to ensure fault-free
operation and a long working life for the product.
We recommend taking out an inspection or maintenance
agreement.
11.3 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.
