Maintenance

Costs Reduced
Eco-white Filter Element
High performance filters are used in the hydraulic circuit and
engine. Longer hydraulic oil, hydraulic oil filter, engine oil and
engine oil filter element replacement intervals significantly
reduce maintenance costs.

Side-by-side Cooling
The oil cooler, aftercooler and radiator
are installed side by side. As a result,
it is very easy to clean the radiator,

Long Greasing Interval
Special hard material is used for the
bushings of the work equipment to
lengthen greasing interval. All
bushing lubrication intervals of work
equipment except arm top bushing
are 500 hours, reducing maintenance
costs.
Large TFT LCD Monitor
Large multi-lingual LCD Monitor
A large user-friendly color monitor enables safe, accurate and smooth work.
Improved screen visibility is achieved by the use of TFT liquid crystal display that
can easily be read at various angles and lighting conditions. Simple and easy to
operate switches. Industry first function keys facilitate multi-function operations.
Displays data in 12 languages to globally support operators around the world.

Excellent Reliability and Durability
High Rigidity Work Equipment
Boom and arms are constructed of thick
plates of high tensile strength steel. In
addition, these structures are designed
with large cross-sectional areas and
generous use of castings. The result is
working attachments that exhibit long
term durability and high resistance to
bending and torsional stress.
Sturdy Frame Structure
The revolving frame, center frame and
undercarriage are designed by using
the most advanced three-dimensional
CAD and FEM analysis technology.
