need to switch the unit off via the red pull tag on the rear of the carriage, then set to mode 3, set the knob vertical, then count the clicks as you turn it clockwise, with mode 3 set pull out the red tag to switch the lift back on, the lift should run, BUT! the safety edges will not operate (what safety edges?) and the seat will not level, best run the lift to the top of the rail
stop it short of the end of the rail, remove the charge ramp and the stop bolted to the rack, set mode 3 and run the lift off the rail, then dismantle it, will need allen keys to undo the rail joints and a pin punch to remove the pin holding the rack together
tbh an aging flow2 isnt worth a lot, if its clean and in good working order, you may get a buyer for it on ebay
