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 the machine against
unintentional start-up. Pull out the main plug in order to do this. Store the plug near the
machine to avoid accidents.
7.4

1. Remove ½ in.-20 bolts from drive plate using a ½ in. impact wrench and ¾ in. socket.
2. Use pry tool to remove assembly from drive plate.
