Problematic deck lift for 1996 Countax C800HE?

Hello.

I am trying to repair my Dad's C800HE as the deck lift is shot. The mower was originally built with the Keyang drive motor fitted to raise and lower the deck, but a mechanic trying to be too clever fitted the latest Hiwin linear actuator, fitted on the newest C series. The actuator burnt out, had to be repaired, and is now shorting, even causing part of the relay system at the back to burn out, and blowing the fuses every 5 seconds.

The problem is, I don't have the correct workshop manual for it. Countax sent me one, but unfortunately, it only covers modern mowers, the oldest model being 1998. And, sadly, the '98 model had a slightly different system to the relic in the garage. Has anyone got a parts list or workshop manual for a 1996 mower? I need to know what parts to get to fix this problem, as the mechanic likely chucked them in the bin.

Thanks!!
