Includes the high-output, low fuel consumption, low-noise and powerful "clean burning engine"
• Includes a tough fuel-efficient clean burning engine that passes the environmentally friendly exhaust emissions regulations. Coupled with a full horsepower control system, this machine really gets a lot of work done.
Maximization of engine output-the new APC microcomputer system
• Oil flow is regulated by the new APC (Automatic Power Control) microcomputer system - a state-of-art electronic control system. The optimal engine torque and oil flow are selected to match the type of job or current operational situation. At all times engine power is used to full effect. This increased power can clearly be used in a wide range of applications.
Function control panel
• Monitoring indicators and touch control switches are all located on an easy-to-use panel to ensure smooth operation.
Self diagnosis system
• The APC system includes a self diagno-sis function that will detect any problem and alert the operator.
The Auto Slow and One-touch Slow systems cut waste of fuel
• When the lever is returned to the neutral position, the synchro control system mini-mizes the hydraulic oil flow through the pump. Several seconds after that, the Auto Slow system reduces engine speed. When the lever is reset at the operating position, the engine recovers initial speed and hydraulic oil flow increases in proportion to the amount of the lever stroke. This cuts losses from unnecessary throttling and waiting for dumping, thereby saving fuel and ensuring low-noise operation. Machine equipped One-Touch-Slow operation which reduces engine speed down to idle simply by a touch of the quick acceleration switch on the lever.
Four operation modes can be selected, according to the operating conditions.
• The operator can select the optimal setting for operation duties and purpose, from among "heavy duty," "general," "fine" and "slow" modes.
• Heavy duty operation mode: Large-scale and heavy duty excavation
• General operation mode: General exca­vation and loading
• Fine control accurate and safe operation, leveling, and slope forming
• Slow operation mode: Delicate tasks on the lever.
The operator can select three speed modes Automatic speed change ensures easy steering
• With a single touch, the operator can select high speed (5.5 km/h), medium speed (3.6 km/h) or low speed (2.5 km/h) modes to suit job site conditions. When the machine is traveling at a high speed, the high speed or medium speed mode is automatically selected to facilitate driveability.
Easy to understand multi-display and recorded warning
• The self diagnosis function displays its results through a simple LCD display and recorded warning. These functions alert the operator to any change in the working condition of machine. Thus the operator is immediately aware of any problem or the necessity to perform maintenance tasks such as refueling or filter changes.
Intuitive "human" controls allow micro adjustments and multiple operations to be performed freely
• Advanced response and outstanding controllability is achieved.
• An improved hydraulic system and APC microcomputer system result in great controllability for fast and smooth multiple operations.
