3.23 Towing 1001/1501/2001
In order to tow away the dumper, the high-pressure circuit on the hydrostatic pump must
be opened and the hydraulic parking brake on both rear wheel motors must be released.
Opening the high-pressure circuit 1001/1501
There are two HP pressure limiting valves on the pump under the floor panel, one on the
upper left and the other on lower left.
Proceed as follows:
☞Stop the engine.
☞Open the floor panel.
☞Loosen locknuts 2 with half a revolution to the left.
☞Turn screws 1 to the right with an allen key until you can feel a firmer resistance.
☞Then screw in a further half revolution.
Screwing in any further damages the valve.
☞Retighten the locknuts
☞You can now slowly tow the machine (max. 2 kph/1.2 mph) over a short distance (max.
1 km/0.6 miles).
After towing the machine, the pressure must be set and the machine put back
into operation by a Wacker Neuson service center.
