I'm curious to know the result of your contact with Kion. Would you be willing to share? if not here, you could email me for privacy.
I was contacted by Kion in regards to my inquiry and have not yet responded to them.
I am factory trained on Linde products and have a lot of experience dealing with the 39x series machines.
Although I have been out of forklift world for almost 4 years, i still may be able to lend a hand with some technical support. There are some things that I figured out a work around for troubleshooting without using Pathfinder.

Good luck.
