ENGINE


The engine is a turbocharged, 4-stroke diesel engine with water cooling, direct injection and charged air cooler that meets EU Step 2 requirements. The engine has been developed especially for excavator use, providing good fuel economy, low noise levels and a long service life. Air Filter: 3-stage, includes pre-cleaner Automatic Idling System: Reduces engine speed to idle when the levers and pedals are not activated resulting in less fuel consumption and low cab noise level.

CAB


The operator's cab has easy access via a wide door opening. The cab is supported on hydraulic dampening mounts to reduce shock and vibration levels. These along with a sound
absorbing lining provide low noise levels. The cab has exellent all-round visibility. The front windshield can easily slide up into the ceiling, and the lower front glass can be removed and stored. The glass is stored in the door. Integrated air conditioning and heating system: The pressurized and filtered cab air is supplied by automatically controlled fan. The air is distributed via 13 vents. Ergonomic operator's seat: The adjustable seat and joystick consoles move independently to accommodate the operator. The seat has nine different adjustments and a seat belt to meet any operator's comfort and safety.

Sound Level:
Sound level in cab
according to ISO 6396
LpA 73 dB(A)
External sound level
according to ISO 6395
75 dB(A)


HYDRAULIC SYSTEM


Mode", is designed for high-productivity, high-digging capacity, high-maneuvering precision and good fuel economy. The summation system, boom, arm and slew priority along with boom and arm regeneration are provides optimum performance. The following important functions are included in the system: Summation system: Combining the flow of both hydraulic pumps to ensure quick cycle times and high productivity. Boom priority: Gives priority to the boom operation for faster raising when loading or deep excavation. Arm priority: Gives priority to the arm operation for faster cycle times in leveling and for increased bucket filling when digging. Slew priority: Supplies priority to the slew operation for
faster slew simultaneous operations. Regeneration system: Prevents cavitation and provides flow to other movements during simultaneous operations for maximum productivity.
Power boost: All digging and lifting forces are increased. Holding valves: Boom and arm holding valves prevent the digging equipment from creeping. Power Max: All function speeds are increased.
