Warning: don't trust the load chart on an old National the way it's printed
I ran a 1998 National 600E last month on a tilt-up job in Fresno and the sheet in the cab gave a slightly higher capacity than the manual I dug up online, which cost me a half day arguing with the PM about where to set up. Turns out somebody had swapped the cab chart from a different boom length, and the manual was the right one. How do you all verify chart numbers on older iron before you commit to a pick?
