If equipment that incorporates hydraulic cylinders is stored outside with the cylinder rods extended, the rods are exposed to weathering. Eventually, the rods will begin to show specks of rust that develop into pits. Once rusting and pitting occur, the rod will destroy the cylinder seal the next time it is activated.
