I actually got ahold of a company Fastec industrial . They have a web site same name. I called them for parts, They are only an importer, they get the jacks from china. BUT they have the owners manual and parts manual on their site. this link should get you to the manual. http://www.fastecindustrial.com/amkt...STRUCTIONS.pdf
Cut and past it in your browser if needed. I would like to find parts but they know of no one with parts, The jacks come into the country as a complete unit and would have to be broken down to get any parts.
