254 Working hydraulics circuit II Switching working hydraulics circuit II to standby mode X Turn the key to position 1 in the ignition lock. or X Connect the equipment to the working hydraulics (see the manufacturer's sepa- rate operating instructions) ( Y page 230). Assignment of flow rate, vehicles with dual-circuit hydraulic system X Make sure that the hydraulic system is switched on ( Y page 230). X Start the engine. X Press button J . The indicator lamp in button J flashes. The Hydraulics input window opens in the on-board computer. The line for working hydraulics circuit II Z is selected. Working hydraulics circuit II is in standby mode.
General notes The flow rate is created by two gear pumps. The flow rate for circuit I is 32 l/min and for circuit II, 55 l/min. The stated flow rates apply to a rated engine speed of 2200 rpm. You can change the flow rate amount for the individual circuits. To do so, however, all flow rates must be turned off beforehand. Hydraulic system X Check the flow rate and, if necessary, increase or decrease the flow rate. To do so, increase or decrease the working speed as appropriate ( Y page 262) Switching the flow rate Activating working hydraulics circuit II X Press the 9 button on the steering wheel or the black button on the control lever until the indicator lamp in button J lights up.
Working hydraulics circuit II is activated. The symbol for working hydraulics circuit II Z is coloured. Switching working hydraulics circuit II back to standby mode X Call up the Hydraulics menu window ( Y page 237). X Using the r or s button, select working hydraulics circuit II. X Press the 9 button on the steering wheel or the black button on the control lever until the indicator lamp in button J flashes. The symbol for working hydraulics circuit II Z has a coloured border. Working hydraul- ics circuit II is in standby mode. Using button L , you can switch the flow rates between working hydraulics circuit I and circuit II.
Switching on flow rate selection Deactivating working hydraulics circuit II X Press button J . The indicator lamp in button J goes out. or X Switch off the hydraulic system ( Y page 230). X Ensure that:
