The cabin is roomy and ergonomically designed with low noise levels and good visibility. A full-view front window and large rear and side windows provide excellent visibility in all directions.
The four cylinders turbocharged and charged air cooled, engine is built for power, reliability and economy. This meets EPA Tier 3 and EUstage 3A emissions regulations.
The advanced CAPO (Computer Aided Power Optimization) system tunes engine and pump power to optimum levels. Multiple mode selections are available for various work loads, maintaining high performance while reducing fuel consumption. Features include auto declaration and power boost. The system monitors engine speed, coolant and hydraulic oil temperature. Contained within the system are self-diagnostic capabilities which display error codes on the monitor.
Optimum Hydraulic Performance
The pump output capacity has been increased.
Auto Deceleration System
When the remote-control valves are in the neutral position for more than 4 seconds, the CPU controller instructs the accel actuator to reduce engine speed to 1,000rpm and 60 seconds later, engine speed is reduced to a low idle automatically. This decreases fuel consumption and reduces cabin noise levels.
Boom & Arm Holding System
The holding valves in the main control valve prevent boom & arm lowering during an extended period in the neutral position.
Boom & Arm Flow Regeneration System
The flow regeneration valve provides smooth and fast operation without cylinder cavitation.
Hydraulically Dampered Travel Pedal
Improved travel controllability & smoother travel has been achieved via shock reducing components.
Pump Flow Control System
When in neutral the pump flow is minimised to reduce power loss. During operation maximum pump flow is delivered to the actuator to increase speed. Movement of the control lever automatically adjusts pump flow, with cylinder speed controlled proportionally.
Power Boost Control System
In power mode the digging force increases about 10%.
One-Touch Decel. System
When the one-touch decel switch is engaged, the CPU controller limits the accel actuator to an 800rpm idle. When the one-touch decel Switch is disengaged the engine speed recovers to its preset rpm.
The CPU controller diagnoses problems in the CAPO system caused by electric and hydraulic malfunctions and displays on the cluster LCD monitor as error codes. The information via this device including engine rpm, main pump delivery pressure, battery voltage, hydraulic temperature and the status of electric switches allows the operator to know the exact operating conditions of the machine. This makes it easier to troubleshoot any problems that occur.
Attachment Flow Control System
Attachment mode provides adequate hydraulic pump flow to each work tool, preventing excess flow and ensuring the regular performance.
