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.
