First, the hydraulic cylinder should be replaced regularly during the use of hydraulic oil, cleaning system screen, to ensure cleanliness and extend the service life.

Second, hydraulic cylinder for each use, should be fully extended, full shrinkage test run, 5 strokes, and then carrying operation. Why do this? It can discharge the air in the system, the preheating system, can effectively avoid the presence of air or water system, caused by gas explosion in the cylinder (or scorch) phenomenon, it will damage the seal, causing the hydraulic oil cylinder inner leakage fault.

Third, control system temperature, oil temperature is too high will reduce the sealing life, long-term high oil temperature, so that permanent deformation of seals, or even completely ineffective.

Fourth, good protection to prevent the outer surface of the piston rod, bump and scratch damage to seals, regular cleaning of hydraulic cylinder pneumatic piston rod sealing dustproof ring parts and exposed on the sand, to prevent sticking into the hydraulic cylinder in the internal damage on the surface of the piston rod is not easy to clean up the dirt

Damage the piston, cylinder, or seal.

Fifth, often check the thread, bolts and other parts of the connection, found loose immediately fastening.

Sixth, often lubricate the connection parts, to prevent oil free state corrosion or abnormal wear.
