  • Door Closing Too Slowly – May indicate internal wear or incorrect adjustment of closing valves.
  • Door Not Latching Properly – Can result from misalignment, weak spring tension, or worn components.
  • Hydraulic Oil Leakage – A sign of internal seal failure that requires immediate attention.
  • Hard-to-Open Doors – Usually caused by excessive spring tension or improper installation.
  • Broken or Damaged Arms – Physical wear or impact damage affecting door movement.
