7.3 Maintenance
Only those repair works are described which occur within the context of maintenance or which
are required to replace wear parts. If you replace parts yourself for specific reasons, the following
instructions and work sequence have to be observed. You should also stock all spare or wear parts
that cannot be supplied quickly. As a rule, production standstill periods are more expensive than
the cost for the corresponding spare part. Screws that have been removed must be replaced with
those of the same quality (strength, material) and design.
Prior to any repair work on the machine and its drives, secure machine against uninten-
tional start-up. Pull out the main plug. Store plug near the machine to avoid accidents.
