Recommendations

1. Relief Valve: Protect the cylinder circuit with a relief valve set at 200 bar.
2. Oil Cleanliness: Check the oil cleanliness (pollution) and prevent it from having strange objects by placing a filter on the cylinder circuit.
3. Bleeding the Circuit: Bleed the circuit by slightly loosening the cylinder fittings before starting up.
4. Welding Precautions:
   • Do not weld on the cylinder tube.
   • Before welding on the rod or the bottom, dismount the cylinder.
5. Storage:
   • For long-term storage, avoid outdoor storage.
   • If outdoor storage is unavoidable, ensure the rod is completely retracted or greased.
6. High-Pressure Cleaning: Protect the rod and oil ports suitably during high-pressure cleaning or blasting.
7. Single-Acting Use: For double-acting cylinders working as single acting, connect the non-used oil port to the tank.
8. Dismounting the Cylinder: If dismounting the cylinder, note that the piston is screwed onto the rod end and fixed with industrial glue. Use industrial glue when mounting again.
