Recommendations:
- Relief Valve: Protect the cylinder circuit with a relief valve set at 200 bar.
- Oil Cleanliness: Ensure the oil is clean and free from contaminants. Use a filter in the cylinder circuit.
- Bleeding: Bleed the circuit by slightly loosening the cylinder fittings before startup.
- Welding Precautions:
- Do not weld on the cylinder tube.
- Before welding on the rod or bottom, dismount the cylinder.
- Storage:
- Avoid outdoor storage for long periods.
- If outdoor storage is unavoidable, fully retract the rod or grease it.
- Cleaning: Protect the rod and oil ports during high-pressure cleaning or blasting.
- Single Acting Usage: For double-acting cylinders used as single acting, connect the non-used oil port to the tank.
- Dismantling: When dismantling, note that the piston is screwed onto the rod end and fixed with industrial glue. Use industrial glue when reassembling.
