Recommendations

• Relief Valve: Protect the cylinder circuit with a relief valve set at 200 bar
• Oil Cleanliness: Check oil cleanliness and prevent contamination by using a filter on the cylinder circuit
• Bleeding: Bleed the circuit by slightly loosening the cylinder fittings before starting
• Welding: Do not weld on the cylinder tube. If welding on the rod or bottom is necessary, dismount the cylinder first
• Storage: Avoid outdoor storage for long periods. If unavoidable, retract the rod completely or grease it
• Cleaning: Protect the rod and oil ports during high-pressure cleaning or blasting
• Single Acting Use: If used as a single-acting cylinder, connect the unused oil port to the tank
• Dismounting: The piston is screwed onto the rod end and fixed with industrial glue. Use industrial glue when remounting the cylinder
