Recommendations:

• Protect the cylinder circuit with a relief valve set at 200 bar.
• Ensure the cleanliness of the oil and prevent contamination by installing a filter in the cylinder circuit.
• Bleed the circuit by slightly loosening the cylinder fittings before start-up.
• Avoid welding on the cylinder tube. If welding on the rod or bottom is necessary, dismount the cylinder first.
• For long-term storage, avoid outdoor storage, retract the rod completely, or grease the rod.
• During high-pressure cleaning or blasting, protect the rod and oil ports.
• For double-acting cylinders used as single-acting, connect the unused oil port to the tank.
• If dismounting the cylinder, note that the piston is screwed onto the rod end and secured with industrial glue. Reapply industrial glue when reassembling.
