Recommendations:

• Circuit Protection: Use a relief valve set at 200 bar
• Oil Cleanliness: Ensure oil is clean and free from contaminants; use a filter in the cylinder circuit
• Circuit Bleeding: Bleed the circuit by slightly loosening the cylinder fittings before start-up
• Welding Precautions:
  • Do not weld on the cylinder tube
  • Dismount the cylinder before welding on the rod or bottom
• Storage:
  • Avoid outdoor storage if possible
  • If outdoor storage is unavoidable, keep the rod fully retracted or greased
• High-Pressure Cleaning: Protect the rod and oil ports
• Single Acting Operation: Connect the non-used oil port to the tank
• Cylinder Dismounting: The piston is screwed onto the rod end and fixed with industrial glue; use industrial glue when reassembling
