About This File
This is the latest (MY 2020+) HS400 service manual--, it is dated December 2019, I got it from Hisun and edited it to correct spelling, add bookmarks, and flag obviously bad information (they had the transmission and shift mechanism section completely fouled up, showing the 2-speed (L-H-N-R) tranny from the HS500+ models.
I inserted a proper transmission shaft (input, counter and output) diagram as well.
It has a great electrical diagram I posted separately a while back...
