How do I access the service codes in the JLG manuals for aerial lifts?

When you work on construction sites, having the right JLG manuals is not just about fixing the machine, it is about keeping people alive because those lifts have serious safety interlocks. I was trying to troubleshoot a boom lift that kept throwing a code and shutting down, and the generic advice online was useless. I finally tracked down the official service manual which had the exact diagnostic flowcharts and hydraulic pressure specs I needed, which you can find through jlg manuals https://jlg.manymanuals.com/ and it saved us a huge repair bill because it turned out to be a simple sensor issue.

This is perfect, I couldn't have figured it out without your help.
