Recommendations:

• Protect the cylinder circuit with a relief valve set at 200 bar.
• Ensure oil cleanliness, and use a filter on the cylinder circuit.
• Bleed the circuit by loosening the cylinder fittings before starting up.
• Do not weld on the cylinder tube.
• Dismount the cylinder before welding on the rod or bottom.
• If long-term storage is necessary, avoid outdoor storage; if unavoidable, retract or grease the rod.
• Protect the rod and oil ports during high-pressure cleaning or blasting.
• For double-acting cylinders used as single-acting, connect the unused oil port to the tank.
• When dismounting, note that the piston is screwed onto the rod end and fixed with industrial glue; use industrial glue when reassembling.
