1. The excavator is equipped with the “O. H. S” (Optimum Hydraulic System) developed by Hitachi.
The “O. H. S” features:
Quick response of the actuators.
Improved precise swinging.
Improved combined operation of each function.
2. The control valve and each circuit are provided with relief valves of sufficient capacity to protect the actuators and other equipment from damage caused by the surge pressure and filter plugging.
3. Travel parking brake is automatically released when any control levers are operated. When the control lever is placed in NEUTRAL, the brake is automatically applied.
4. Swing parking brake is automatically released when any control levers are operated. When the control lever is placed in NEUTRAL, the brake is automatically applied.
5. The excavator is equipped with an accumulator in the hydraulic system in order to operate front attachment for a few seconds after the engine has stopped. The accumulator is charged with high pressure gas; do not attempt to remove or disassemble it, and do not expose the accumulator to flame.
6. The excavator is equipped with an independent oil cooler and circulation pump for the pump transmission, which functions to cool pump transmission oil.
