1. Loosen the lock nut (K).
2. Screw or unscrew the cushioning component. For stability reasons, the distance d may not exceed
the values from the following table (

Maintenance and care
Cleaning and maintenance:
1. Clean the belt system and the guide rail with a soft cloth as required. Any agents that do not dam-
age the material may be used as cleaning agents.
2. Avoid cleaning agents which will damage the belt system (PU).
Excessive friction or grease-solvent cleaning agents (e.g. soap suds) will damage the grease layer.
