Generally, this could be caused by an issue with worn seals or visible imperfections on the surface in the rams causing added resistance. Additional force would be needed to retract and remove these rams from a cylinder. Typically, we recommend removing a unit in this condition from service to be disassembled and evaluated so a repair can be made.
