Hi,
I’m leaving what I’ve learnt here in case it helps anyone else in the future.
When replacing the seat on the rail, I used 2 people. One to lift, the other to align. The seat and carriage assembly is very heavy, but that looked like the better option than trying to disassemble. If you’re alone you’ll need to disassemble. Get your directional commands organised before starting!
There is a group of 3 copper contactors on the back side that run up the copper bus bar on the back side of the rail. I learnt the hard way that you can disable the spring action by looking a thin piece of wire into the holes in the sides. Push in the contractors whilst also pushing the wire through and you will fix the springs at Thier minimum extension. This helps to get them out of the way of damage when trying to align the carriage.
With the carriage seated I found the most reliable way to get it to wind down the rack is too lower the seat, arm rests, and foot plate to help prevent safety alarms and the carriage not moving. Once it’s wound on a little way it’s much more forgiving.
A little bit of tinkering and testing with the covers etc is all that’s then needed to finish the job! My disabled missus is delighted!
