.
Sliding front and side windows provide improved ventilation.
.
A large sunroof offers upward visibility and additional ventilation.
Comfortable Operator Environment
.
The control levers and seat can be adjusted to provide maximum
operator comfort.
.
The seat is fully adjustable for optimum operating position,
reducing operator fatigue.
.
Console boxes slide forward and backward for improved accessibility.
.
The proportional pressure controls reduce unnecessary exertion while
ensuring precise operation.
.
Large windows allow excellent visibility in all directions.
Low noise design
.
The Robex 7A series is designed with low operation noise in mind.
.
Hyundai engineering made efforts to keep interior and exterior noise levels
to a minimum.
.
The cab's noise levels have been additionally reduced by improving the
door seals for the cab and engine compartments.
.
An insulated diesel engine compartment with sound-damping material
also reduces noise.

Improved Intelligent Display
Instrument Panel is installed in front of RH
console box. It is easy to check all critical
systems with easy-to-read indicators.
Minimization of Shock and Vibration through
a Cab Mounting System
The application of the Viscous Mounting system to the cabin
support provides the operator with a smoother ride. The operator
work efficiency will increase as the shock and noise level in the
cabin decreases.
Operating Environment
Storage box and Cup Holder
An additional storage box and cup holder are located behind the
operator’s seats so to keep food and beverages cool or hot.
Wide Cab with Excellent Visibility
The cab is roomy and ergonomically designed with low noise level
and a good visibility. A full view front window and large rear and side
windows provide excellent visibility in all directions.
Wide, Comfortable Operating Space
All the controls are designed and positioned
according to the latest ergonomic research.
Reinforced pillars have also been added for
greater cab rigidity.
Smooth Travel Pedal and Foot Rests

Automatic Engine
Overheat Prevention
If the engine coolant temperature
gets too high, the CPU controller
lowers the engine speed and cools
the engine.
Anti Restart System
The new system protects the
starter from re-starting during
engine operation, even if the
operator accidentally turns the
start key again.
Power boost
control System
When the power boost system is
activated, digging power increases
about 10%. It is especially useful
when extra power is temporarily
needed, for instance, when digging
hard earth and rock.
Automatic Warming-up
System
After the engine is started, if the
engine coolant temperature is low,
the CPU controller increases the
engine speed and automatically
increases the pump flow rate so to
warm up the engine more
effectively.
Advanced Hydraulic System
The advanced CAPO (Computer
Aided Power Optimization)
system maintains engine and
mutual pump power at optimum
levels. Mode selections are
designed for various work
loads, maintaining high
performance while reducing
fuel consumption.
Features such as auto
deceleration and power boost
are included in the system. The
system monitors engine speed,
coolant temperature, and
hydraulic oil temperature.
Contained within the system
are self diagnostic capabilities
which are displayed by error
codes on the cluster.
POWER MODE
H mode: High power
S mode: Standard power
WORK MODE
: Heavy duty work
: General work
: Breaker
USER MODE
M mode: Maximum Power
U mode: Memorizing Operator’s Preferable Power Setting
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
1000 rpm. This decreases fuel consumption and
reduces cab noise levels.
Max. Flow Cut-off System
For precise control and finishing work, the Max.
Flow Cut-off System reduces pump flow, thus
allowing smooth operation.
Self Diagnosis System
The CPU controller diagnoses problems in the
CAPO system caused by electric and hydraulic
malfunctions and displays them on the LCD
monitor of the cluster through error codes. This
controller has the capacity to identify 48 distinct
types of errors. The information from this device,
such as engine rpm, main pump delivery
pressure, battery voltage, hyd. temperature, and
the state of all types of electric switches,
provides the operator with an exact condition of
the machine. This instrument makes it easier to
troubleshoot the machine in case of failure.
One Touch Deceleration System
When the one touch deceleration switch is
pressed, the CPU controller controls the
accelerator actuator to reduce engine speed to
850 rpm. 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.
Boom & Arm Holding System
The holding valves in the main control valve
prevents 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.
Hydraulic Damper in Travel Pedal
Improved travel controllability & feeling during
movement of the machine by use of shock
reducing material.
