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.
