ENGINE

 

The engine is a low-emission, turbocharged, 4-stroke diesel engine with water cooling, direct injection and aftercooler, especially developed for excavator use. The machine can work at any job site, contributing to good fuel economy, low sound level, less wear and a longer life. Air filter: 3-stage, includes pre-cleaner Automatic idling system: Reduces the engine speed to an idling speed when levers and pedals are not activated.

HYDRAULIC SYSTEM

 

The hydraulic system, named "Automatic Sensing Work Mode", is designed for high productivity, high digging capacity, high maneuvering precision and good fuel economy. The summation system, boom priority, arm priority, swing priority, and regeneration system of the arm flow are provided for the best operation. The following important functions are included in the system ; Summation system: providing full use of the pump oil flow. Boom priority: gives priority to the boom operation for fast raising when loading or deep excavating. Arm priority: gives priority to the arm operation for faster cycle times in leveling and for increased bucket filling when digging. Swing priority: supplies priority to the swing operation for faster swing during simultaneous operations. Regeneration system: enhances the cylinder life cycle to prevent cavitation and provides priority to other movements during simultaneous operations. Power boost: All digging and lifting forces are increased. Holding valves: Boom and arm holding valves are standard. Power Max: All function speeds are increased.

CAB

 

Easily accessible cab with a wide door and lined with soundabsorbing material. The cab, which is supported by hydraulic dampening mounts to reduce shock and vibration, has all-around visibility. The front windshield can slide up into the ceiling and the lower front glass can be removed. Integrated air-conditioning and heating system: The pressurized and filtered cab air is supplied by a 4-speed fan. The air is distributed via 8 vents. Ergonomic operator's seat: The adjustable seat and control consoles move independently to accommodate the operator well. The seat has eight different adjustments and a seat belt to meet any operator's requirement. Sound level: Approved according to the Directive 86/662/EEC.
