252 Working hydraulics circuit I X Move the control lever all the way in direc- tion B for approximately one second. The snow plough is in the float setting and is applying its full weight to the road. The indicator lamp in button O flashes. X Press and hold red button A . Switching the continuous consumers on/off Pressing the snow plough briefly onto the road X Make sure that snow plough load relief is switched on. Hydraulic system X Move the control lever in direction B until the snow plough pushes the road with the desired pressure. The indicator lamp in button O flashes. Snow plough load relief enters standby mode. X To switch on snow plough load relief again:
move the control lever into the neu- tral position. General notes Continuous consumers Switching the continuous consumers to standby mode ! 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. X Connect the attached equipment (see man- ufacturer's operating instructions) either to red hydraulic connection 1 or to green hydraulic connection 3 ( Y page 230). You can connect equipment with a constant flow rate either to red hydraulic connection 1 or to green hydraulic connection 3. If you then switch on the continuous consumer, the attached equipment is supplied with a con- stant flow rate.
The attached equipment then cannot be controlled with the control lever. X Start the engine. X Make sure that the hydraulic system is switched on ( Y page 230). X Ensure that unnecessary continuous con- sumers and snow plough load relief ( Y page 248) are switched off. X Continuous consumer to red hydraulic connection 1: press button Q . The indicator lamp in button Q flashes. The Hydraulics input window opens in the on-board computer. Red hydraulic connec- tion 1 for continuous consumer Z is selec- ted.
