I have a JLG 1930ES scissor lift on my property and I needed the correct part number for the annual safety inspection checklist that the rental companies require. The official JLG manuals portal can be overwhelming, but I found a dedicated page that aggregates all the operator and service manuals by model. You can search for your specific machine right here
https://jlg.manymanuals.com/ for jlg manuals and it has the operation and safety manual listed under the model number which includes the decal diagrams and the load capacity charts you need to keep on the machine.
