4.3 Maintenance
If you replace parts yourself for specific reasons, the following instructions and work sequence
have to be observed:
• 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).
