Possible causes to examine for this symptom
These causes are preliminary assessments. The same symptom can have different causes in different circuits.
Examine setting changes together with end-of-stroke cushioning.
How to check: Record whether harshness occurs at startup or the stroke end. A qualified technician should compare command ramps, cylinder cushioning and mechanical play with recorded settings.
Possible solution: Correct confirmed ramp or cushioning faults within manufacturer limits. Remove mechanical play and perform controlled tests while preserving safety functions.
