There is a good chance you will damage the OSG and the tilt system. See my “repair diary” video clips online. Also, see my how-to acquire and construct an Acorn curved stairlift from used, for free, or nearly-free. There is NO MARKET for used Acorn curve stair lifts atm. I have three non-clients that I am helping get rid of their Acorn curved stairlifts that still work. (Their kin who used these curved stair lifts died suddenly, like a million people worldwide, in the last few years. Now these curved stair lifts are just going to metal scrap dealers.)
Fyi.. surf for Acorn 180 Programming Anywhere in the World by Zoom, if you need help.
