Lifting weight is not a problem and once the weight I up the cylinders are not lowering by the weight. Down is not a problem and goes smooth. Anyone recognize this behaviour? I guess it's the pump or oil filter or maybe air in the oil suction line, but before I start do disassemble everything, I was hoping to find someone who recognize this and has experience with the solution. Thanks for your input!</p></blockquote><p></p>
