Komatsu — 3.3.5 MACHINE CONTROLS

INSTRUMENTS AND CONTROLS 9 - “SUPER FLOW” HYDRAULIC SYSTEM CONTROL (5 LINEE) (IF INSTALLED) q Avoid connecting any equipment to the hydraulic lines before said equipment has been correctly installed from a mechanical point of view and locked to the machine front coupling. q Avoid connecting any manually-controlled equipment or tool (for example, hand hammer) to the hydraulic lines while the equipment/tool is working. q Connect the hydraulic lines only with the engine off and the parking brake applied. q To avoid serious injury, always operate the equipment while seated in driving position. Do not allow anyone to get too close the machine or the equipment.

q Read the contents of the equipment instruction manual carefully before using the machine or carrying out main- tenance operations. The Super Flow hydraulic controls can be used when the ope- rator needs to increase the oil delivery to the hydraulic system of the equipment. With the SUPER FLOW hydraulic system it is possible to use equipment that require a high-flow hydraulic line (left) and at the same time a standard-flow hydraulic line (right) with limited oil flow for secondary functions (auxiliary hydraulic kit control pedal).

Thanks to the Super Flow hydraulic control, the operator can use two independent hydraulic circuits (positioned on the right and on the left side of the loader arm). In the Super Flow hydraulic system, the standard-flow lines are positioned on the right side of the arm. The quantity of oil in the right hydraulic li- nes and the flow reversal are controlled by the pedal (see "3.3.5 pos. 4 - AUXILIARY HYDRAULIC KIT CONTROL PE- DAL (IF INSTALLED)"). The left hydraulic lines are used only for equipment requiring high flow rates and are controlled by the buttons (1) and (2) on the left joystick.

To deliver oil to the equipment, press the push button (2) (red LED on the button ON); press the button again to stop the oil flow in the hydraulic lines completely (red LED OFF). To deliver the oil flow in the reverse direction, press the button (1) and keep it pressed. Release the button (1) to restore nor- mal operating conditions. 92 WARNING
