Maintenance Tips for Hydraulic Cylinders

Regular maintenance ensures longer service life and lowers repair costs.

• Keep Hydraulic Oil Clean
  Contaminated oil is a major cause of cylinder failure. Regularly check and replace hydraulic oil to avoid seal damage.

• Replace Seals Periodically
  Seals are crucial for preventing leakage and maintaining pressure. Friction, temperature, and chemicals wear them out over time.

• Lubricate & Protect Piston Rods
  Piston rods are exposed to dirt, dust, and moisture. Keep them clean and lubricated to prevent corrosion and seal wear.

• Inspect Cylinder Condition
  Check for scratches, bends, pitting, or leaks on the piston rod and joints. Early detection prevents costly breakdowns.

Installation Notes

• Double-check model, machine type, and installation dimensions before assembly.

• Clean all filters, valves, pipelines, injectors, and radiators before installation. Replace filters and oil on schedule.

• Use correct seal kits and components during repair. Ensure plunger and rings are installed in the right direction and gaps.

• After assembly, operate the system back and forth to remove excess air before normal use.
