Looks like there are no quick disconnect fittings that came with this HD9 lift. How is everyone plumbing in to the air supply? The instructions are of little help.
I run quick connect ****** to on push button then orange coil hose from harbor freight with quick coupler for now but in end they say run a regulator and water separator and oiler or your warranty is void..... you can get a decent one off ebay for 22.00 this is one that I have small enough to mount on the upright post. either mount self taping screws or bolts or fab bracket on other motor mount plate you don't use.
if don't have one yet just shoot some wd40 in air line near the lock cyl it will really get them moving good they are really slow at first.
