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.

Wacker Neuson WL60, WL70 Common Problems This Manual Covers
Wacker Neuson WL60/WL70 loader won't travel forward or reverse, engine bogs down hard under load
Check the drive test ports before pulling anything apart; the travel drive chapter starting on page 213 maps every test port and high-pressure valve on the variable displacement pump. Measure charge and high pressure at those ports, inspect the manifold hose routing for kinks, and torque any replaced M8 high-pressure limiting valve to 22 Nm.
Manual Section: Travel Drive p. 213Engine cranks slowly or won't start on cold mornings, dash lights dim while cranking
Test battery voltage under load; the 12 V system runs a 95 Ah battery and it must hold voltage while cranking. Clean and tighten both ground straps, then verify charging output with the engine running: the alternator is rated 120 A in the electrical specs on page 15. Replace the battery if it fails a load test.
Manual Section: Electrical System p. 15Steering wheel vibration and clunking from the axles after tire service or transport
Torque every wheel nut with a torque wrench, never a bar: M14 x 1.5 nuts to 150 Nm, M18 x 1.5 to 285 Nm, and M20 x 1.5 to 400 Nm, per the table on page 23. Recheck after a short work cycle and inspect stud threads and rim contact faces before refitting any wheel.
Manual Section: Introduction p. 23Brake pedal feels spongy and parking brake barely holds on a grade
Check the brake fluid level first: it should sit 2.0 to 1.5 cm below the lid level, as specified on page 141. Top up with clean fluid and bleed the service brake if the pedal stays soft. Inspect pad thickness and follow the brake pad basic setting procedure in the brakes chapter starting on page 241.
Manual Section: Brakes p. 241Low engine oil pressure warning flickers at idle when the engine is hot
Check the oil level on level ground with the engine off. If a change is due, drain the sump hot, replace the filter, and fill with 8.0 L of oil including the filter, per the capacity table on page 83. Follow the maintenance schedule and use only the approved motor oil specification from the engine chapter.
Manual Section: Maintenance p. 83Frequently Asked Questions
How do I reset the low oil indicator on a Wacker Neuson WL60?
To reset the low oil indicator, you can use the accelerator pedal position method. With the ignition switch on and engine speed at 0 rpm, press the accelerator pedal to 100% for 15-20 seconds, then 0% for 15-20 seconds, repeat this cycle twice, and finally press to 50% for 15-20 seconds. The warning display will flash for 3 seconds to acknowledge the reset. p. 106
What are the general tightening torque specifications for M10 bolts on the Wacker Neuson WL60/WL70?
For M10 bolts with untreated, non-lubricated surfaces, the tightening torque depends on the property class: 46 Nm for class 8.8, 67 Nm for class 10.9, and 79 Nm for class 12.9. p. 23
How do I clear the service interval on a Wacker Neuson WL60?
The service interval warning can be reset using the accelerator pedal position method or a dedicated switch connected to terminals K55 and K77. For the pedal method, follow the sequence of pedal positions (100%, 0%, 100%, 0%, 50%) for 15-20 seconds each with the ignition on and engine at 0 rpm. p. 106
What is the engine oil capacity for the Perkins engine in the WL60/WL70?
The engine oil capacity for the Perkins engine, including the filter, is 8.0 liters (2.1 gallons). p. 83
What is the correct procedure for bleeding the fuel system on the WL60/WL70?
You can bleed the fuel system by turning the starting key to position I for one minute, which allows the electric fuel-feed pump to bleed the system automatically. Alternatively, you can use the hand pump located on the fuel pre-filter. p. 102
