The equip- ment fitted can then be set, uncontrolled, in motion.
Persons in the area of danger can be seriously or even fatally injured. Make sure that only one piece of equipment at a time is ever connected to hydraulic connec- tions of the same colour. Hydraulic system Deactivating/activating the hydraulic system X To deactivate: press button H . The indicator lamp in button H lights up. The entire hydraulic system is deactivated. Operation of the hydraulic system using the buttons or the control lever is disabled. The working hydraulics may be fitted with up to eight hydraulic connections at the front and up to four connections at the rear. The hydraulic connections are integrated into the front and rear bumpers.
The hydraulic con- nections are colour-coded. Hydraulic connections 1 to 8 can be propor- tionally controlled with the control lever. You can connect attached equipment with a con- stant flow rate either to hydraulic connec- tion 1 or hydraulic connection 3; switching continuous consumers on/off ( Y page 252). X To activate: press button H . The indicator lamp in button H goes out. Operation of the hydraulic system using the buttons or the control lever is enabled. Hydraulic connections Important safety notes G WARNING When you switch off the hydraulic system, a residual pressure remains in the hydraulic system. This may cause attached equipment to move or continue to run.
There is a risk of an accident and injury. R After switching off the hydraulic system, always secure the attached equipment by closing the cutoff valve on the equipment. R Insert the transport lock. R Make sure that nobody is in the danger zone of the attached equipment. Vehicle front, left-hand side : Red hydraulic connection 1, circuit I ; Red hydraulic connection 2, circuit I = Green hydraulic connection 3, circuit I ? Green hydraulic connection 4, circuit I ! Only switch on the hydraulic system when it is connected to an item of attached equipment. There is otherwise a risk of damage to the hydraulic system.
