Detailed instructions for use are in the User's Guide.
[. . . ] The proportional pressure controls reduce unnecessary exertion while ensuring precise operation. Large windows allow excellent visibility in all directions.
Low noise design
. The Robex new 7A series is designed with low operation noise in mind. Hyundai engineering made efforts to keep interior and exterior noise levels to a minimum. [. . . ] Once this switch is pressed again, the engine speed recovers to its preset RPM.
Pump Flow Control System
In neutral position: Pump flow is reduced to a minimum to eliminate power loss. In operation: Maximum pump flow is delivered to the actuator to increase the speed. With movement of the control lever, pump flow is automatically adjusted and the actuator speed can be proportionally controlled.
NEW MODE CONTROL SYSTEM
Auto Deceleration System
When remote-control valves are in neutral position more than 4 seconds, the CPU controller instructs the accelerator actuator to reduce engine speed to 1, 000 rpm. This decreases fuel consumption and reduces cab noise levels.

Boom & Arm Holding System
The holding valves in the main control valve prevent the boom & arm from dropping over an extended period in neutral position.

Arm Flow Regeneration System
Arm flow regeneration valve provides smooth arm-in operation without cylinder cavitation.
1 POWER MODE
H mode: High power S mode: Standard power
Max. Flow Cut-off System
For precise control and finishing work, the Max. Flow Cut-off System reduces pump flow, thus allowing smooth operation.
2 WORK MODE
: Heavy duty work : General work : Breaker
Hydraulic Damper in Travel Pedal
Improved travel controllability & feeling during movement of the machine by use of shock reducing material.
3 USER MODE M mode: Maximum Power U mode: Memorizing Operator's Preferable Power Setting

CUMMINS QSB6. 7 Engine
The six cylinder 4 cycle Turbo Charged Engine with Charged Air Cooling, Has High Power output, Reliability, economical, and low emission. This engine meets Tier III emissions regulations.
The Definition of Progress
The Quantum System B Series 6. 7-liter engine combines full-authority electronic controls with the reliable performance. The electronics with the QSB6. 7 have been proven with our high-horsepower productsworking in the harshest, most demanding environments-search as dusty, non-stop mining operations while meeting emissions regulations worldwide. The QSB6. 7 features 24 valve designed with centered injectors and symmetrical piston bowl. The combination of improved airflow and evenly dispersed fuel results in increased power, improved transient reponse and reduced fuel consumption.
Increased Higher Performance
Reinforced Bucket and Bucket Linkage
To prevent excessive wear of pins and bushes, sealed joints have been applied. Bucket link design incorporates high durability and anti wear characteristics. Additional reinforcement plates on cutting edge section are welded. Thicker steel and an additional lateral plate are put in place to reinforce the bucket.
Strong and Stable Lower Frame
Reinforced box-section frame is all welded, lowstress, high-strength steel. It guarantees safety and resistance against external impact when driving on rough ground and working on wet sites through high tensile strength steel panels, with protection cover for transmission.
Powerful and Precise Swing Control
Improved shock absorbing characteristics make stopping swing movement a precise and smooth action.
Large Toolbox & Safe Footholds
Anti-slip footholds and wide toolbox improved safety and convenience.
