From lift cylinder teardown through drive axle and brake repair to control card setup, this JLG 26MRT service manual PDF (OEM 3120892) walks every system on this scissor lift across 62 pages. Hydraulic schematics map the lift, steer, and drive circuits so you can trace a pressure problem line by line, and wiring diagrams do the same for the electrical side. Troubleshooting fills roughly the final third of the book, pairing symptoms with hydraulic circuit checks that end at a specific component. Check drive pump output against the rated 56.8 lpm (15 gpm) at 3,000 rpm, then torque the wheel lug nuts to 122 Nm (90 ft lb) on reassembly. A drifting platform won't say which holding valve let go. Bookmarks and a live text layer put the cylinder checking procedure two clicks from the cover.
