When a WL60 starts creeping into gear too early, or a WL70 will not reach travel speed, the fault hides in the hydrostatic drive, and you can only pin it down with factory pressure values. This Wacker Neuson WL60, WL70 service manual PDF, factory document 1000352039, packs 412 pages of exactly that for both wheel loaders. Wiring diagrams map every fuse, travel function and hydraulic control circuit, while hydraulic schematics cover the loader valve, pilot control and telescopic boom across each build variant. Travel drive troubleshooting runs from no forward travel through severe engine droop to weak traction, each symptom traced to test ports on the variable displacement pump. Check boost pressure at those ports, hold your brake fluid 1.5 to 2.0 cm below the lid, and torque M14 x 1.5 wheel nuts to 150 Nm. Adjusting inching by feel never ends well. Pay once and the bookmarked, keyword-searchable file stays yours for the life of the loader.
