Hydraulic Cylinder Maintenance Guidelines
Proper maintenance extends service life and ensures reliable performance
  • Regular Hydraulic Oil Replacement: Scheduled oil changes maintain system stability and protect internal components.
  • Cleaning the Piston Rod Surface: Remove dirt from dust seals and exposed rod area to prevent contaminants from entering the cylinder.
  • Lubricating Connection Points: Apply lubrication to joints to prevent rust and abnormal wear.
  • Checking Hydraulic System Pressure: Periodically test system pressure to keep it within safe operating range.
Storage Recommendations

For extended out-of-service periods, store the cylinder fully retracted to minimize piston rod exposure and prevent rust.
