I have the factory service manual available for the Buck 400. Just send me a message with your email and I'll get it to you. Although there is no charge for this, it would be great if you would visit my website where you could donate any amount to help do things like this with others who need it. Again, there is no charge for this manual, and no obligation to donate. But if you did, I would thank you for sure. Have fun on the trails. www.warriorsoffroad.com
As an ATV owner (old one BTW), I often come across a search for various owner's manuals, service guides, parts manuals, etc. Therefore I shurely understand how hard it could be to find suitable manuals. Therefore, I present to your attention a website that contains various instructions for ATVs from top brands: https://www.ATVownersmanual.com
Currently only 3 manufacturers are represented here: Can-Am, Polaris, Yamaha - and only about 1200 instructions for various models. Very soon other brands and manuals will be added.
Main pros of the website: all files are in PDF and downloadable so you can use offline. Navigation structured by brand, year and model. There is no advertising yet.
I am happy to hear criticism and recommendations. If you have missing or rare instructions, send them to PM or to the website's email: info [...at...] atvownersmanual [...dot...] com.

Here is the Service Manual for the 2017 Cub Cadet Challenger 750 and it is compatible with the Hisun 500/700 manual as well.
I paid $45 for it but I want to share with everyone because they are a pain in the ass to find.
