Can anyone tell me why? I have replaced both lift cylinders in the past few years. Thanks in advance, Joe [Reply]   [No Email]

I would check the cylinders first before going into the valve. I would guess that it uses o-ring seals rather than seals like an industrial loader and it's not uncommon for them to leak in a relatively short period. [Reply]  [No Email]
