Jlg
JLG service manuals in PDF, from the company John L. Grove started in McConnellsburg, Pennsylvania, in 1969: 600S and 601S telescopic booms, E2-series and RT scissor lifts, G-series and SkyTrak telehandlers, and the T350 and T500J trailer-mounted lifts. Books for JLG’s Toucan, Liftlux, and SkyTrak lines are here as well.
JLG numbers its manuals with seven- and eight-digit publication codes starting 312. The 600S service and maintenance manual, 3120840, covers five boom variants in 272 pages, from the M46 variable displacement pump to a section on the JLG hand held analyzer, including connection and access levels.

Choosing the Right JLG Manual
For electrical faults on a trailer lift, the T350 and T500J troubleshooting manual, 3121203, traces CANBUS failures and solenoid open and short circuits with connector pinouts for each control module. The 601S boom and G6-42A telehandler books sit in Repair Manuals. Parts Manuals cover the 1932E to 2646E and CM-series scissors, the 26MRT, and the 40ic and 45ic.
Which publication number should match my JLG machine?
JLG’s 312 numbers each belong to a model family. The E2 scissor book, 3120737, covers six models from the 1532E2 to the 3246E2 in 86 pages, including the JLG SMART System chapter. The SkyTrak 6036 to 10054 manual, 31200353, ends with a full chapter on Stabil-TRAK tests and boom interlock troubleshooting.
Do I need a JLG account or software to open these?
No account, but one tool: the hand held analyzer procedures in the 600S book assume you have the JLG analyzer to read the machine. The G10-55A and G12-55A telehandler manual and the Toucan E18MJ and E26MJ book need nothing beyond a PDF reader.
