4.8. Dump valves
Dump valve 1. (1)
Allows operation of the crane functions. To prevent high
pressure and thereby unnecessary heating of the oil there
is an automatic dumping function. When no lever
movement has been made for 3 seconds the dump valve is
opened and the oil is returned directly to the hydraulic tank.
As soon as the operator moves a lever the valve closes.
Dump valve 2. (2)
Allows operation of the stabiliser extensions and legs only
when this valve is activated. The dump valve 2 will be placed between the main control valve and
the stabiliser control valve. The dump valve 2 must be activated from the user panel before the
stabiliser system can be controlled.
