Manual Extract Towing:
Function
Machines with hydrostatic drives should only be towed when a connection is made in the drive pump between the high pressure and low pressure sides. To enable this, the high pressure safety valves in the pump have a by-pass function. That means, when screw (1) is turned the valve tension is released and the oil can flow between the high pressure and low pressure sides.
Bypass function
Release the locknut and srew in the screw (1) until the top of the screw is level with the locknut.
Tighten the locknut.
Use publication VEBM120100 with the WA115-3 model details to select the appropriate documentation. Refer to Safety within its stated document and equipment scope.
