IR / Skyjack 843D Max Fork Width??

Hello!

I'm trying to find information on the maximum fork width for an IR / Skyjack 843D. I'm not looking for the width of the fork its self, but the out-to-out distance of the forks at their farthest setting on the frame.

Its hard to find detailed specifications on these forklifts. Anyone have advice on where to get more info than the overview spec manuals?

Thanks!
