|
|
|
| Rear Emergency Exit Window |
Storage box and Cup Holder |
|
 |
- Rear Exit Window is designed with easy exit for operator's safety.
|
- An additional storage box and cup holder are located behind operator's seat, and it keeps food and beverages cool or hot.
|
|
|
| Smooth Travel Pedal and Foot Rests |
Easy-to-Reach Control Panels |
|
 |
- Smooth travel pedal & foot rest ensures operational efficiency.
|
- Switches and other essential controls are
located near the operator. This helps keep Operator movement to a minimum,
enhancing control with less operator fatigue.
|
|
|
| Strong and Stable Lower Frame |
|
- Reinforced box-section frame is welded, low-stress, 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 highly durable upper and lower rollers and track guards.
- Long undercarriage incorporates heavy duty excavator style components.
- X-leg type center frame is integrally welded for maximum strength and durability.
|
|
|
| Track Rail Guide & Adjusters |
|
- Durable track rail guides keep track links in place.
- Track adjustment is made easy with standard grease cylinder track adjustors and shock absorbing springs.
|
|
|
| Powerful and Precise Swing Control |
Reinforced Bucket and Bucket Linkage |
|
 |
- Improved shock absorbing characteristics make stopping a precise and smooth action
- All hydraulic aggregates are well tested for maximum efficiency and durability.
|
- Sealed and adjustable bucket linkage provides less wear of pins and bushes as well as silent operation.
- The design includes bucket link durability and anti wear characteristics.
- Additional reinforcement plate on cutting edge section. Reinforced bucket is made with thicker steel and additional lateral plate.
|
|
|
| Advanced CAPO 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 and maintaining high performance while reducing fuel consumption.
- Features such as 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.

| Working Ranges |
 |
| |
|
| Arm Flow Regeneration System |
| Arm flow regeneration valve provides smooth arm-in operation without cavitations. |
| 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.
|
| One Touch Deceleration |
| When the one touch deceleration switch is pressed once, the CPU controller controlling the accelerator actuator brings the engine rpm to low idle rpm. Engine speed will be recovered to its pre-selected rpm in case the button is pushed once more. |
| Automatic Engine Overheat Prevention |
If the engine coolant temperature gets too high, CPU controller lowers the engine speed and cools the engine.
|
| Anti Restart System |
| The new system protects the starter from restarting 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, or if the bucket teeth are stopped by a stubborn tree root. |
| Automatic Warming-up System |
|
After the engine is started, if the engine coolant temperature is low, the CPU controller increases the engine speed automatically to warm up the engine more effectively. |
| Maximum flow cut-off system. |
| For precise control & finishing work, the maximum flow cut-off system reduces pump flow, thus allowing smoother operation. |
| Auto Deceleration system |
- If the remote control valves are left in neutral position more than 4 secs, CPU controller lowers the engine speed to 1100rpm.
- Decreased fuel consumption.
- Reduced cabin noise level.
|
| Hydraulic Damper in Travel Pedal |
Improved travel controllability & feeling
by shock reducing when starting and
stopping. |
