PERFORMANCE
AND FINE
CONTROL
Machine representative of
global product. Options
may not be available
in all markets.
Trias II: Three hydraulic
pump power to the boom,
arm and bucket
The boom and
arm are more
responsive due to
direct oil flow to
each actuator
The pumps are controlled
electronically for improved
efficiency and lower fuel consumption
10
The SCR system injects urea
into exhaust gas (red) to reduce
NOx from emissions
ZX250LC-6 | ZX300LC-6 | ZX345USLC-6 | ZX350LC-6
TRIAS II
The TRIAS II three-pump system ensures that the boom, arm,
and bucket are responsive and extremely hydraulically efficient,
which also results in better fuel efficiency.
Three solenoid valves ensure fine and sensitive front
attachment control.
Arm recirculation cancel system
The system increases arm roll-in speed in low-load conditions.
Boom recirculating system
By recirculating the
pressurized oil in
the bottom of the
boom cylinder when
lowering the boom, the
pressurized oil from the
pump can be efficiently
used by the arm,
increasing arm speed.
Boost system
During arm roll-in and
boom raise operations,
excessive pressurized
oil from the boom rod
flows to the arm cylinder
lower region, providing
responsive arm operation.
ZX350LC-6
H/P (High Power) mode
H/P mode increases
engine speed and pump
output torque when
additional speed and
power are needed during
operation.
Power boost
Power boost enhances
digging force up to 10%,
improving excavating and
lifting performance.
Machine performance
The ZX250LC-6, ZX300LC-6, ZX345USLC-6, and ZX350LC-6 are
equipped with two extra spools in the control valve, easing the
installation attachments that require higher oil demand.

MORE COMFORT
FEATURES
Enhanced comfort controls are at your fingertips
in the refined cab of ZAXIS-6 excavators, giving
you the power to perform with ease.
User-friendly monitor
A large 7-inch LCD monitor allows the operator to check
machine status at a glance in up to 32 languages.
Improved visibility
The optional front guard has been redesigned and improved,
providing the operator with an even better view of the job site.

advanced music system all contribute to the ultimate working
environment. The addition of an adjustable sun visor reduces
glare on those days when the sun is low in the sky.
Advanced audio system
The AM/FM radio is readily accessible
from the monitor, and an auxiliary
socket for devices such as MP3
players is linked to the sound system.
This choice of entertainment helps to
provide an enjoyable and productive
working environment.
Ease of use
A USB port in the cab enables operators
to charge smartphones and tablets
while they work for added convenience.
Cool, quiet cab

DURABILITY
COMES
STANDARD
Enhanced fuel circuit
A high-performance water separator and
cold fuel resistance valve are integrated into
the pre-filter for added protection against
moisture. In addition, a large-capacity
electric fuel pump supplies an appropriate
amount of fuel to the engine for improved
performance.
14
Save fuel
Hydraulic loss is decreased by TRIAS II
technology. It reduces the hydraulic oil
returned to the tank due to the cooperative
control of the pump and valve. This helps to
lower fuel consumption by up to 19% in ECO
mode with the same productivity.
Engine protection
The combustion chamber is made from
stronger materials, and the revised shape
of the piston is designed to achieve cleaner
emissions. These features will further
enhance the reliability of the engine.
ZX250LC-6 | ZX300LC-6 | ZX345USLC-6 | ZX350LC-6
Reinforced Undercarriage
New shape of the lower roller
The lower roller has been redesigned to
further help prevent mud ingress.
• Long-term durability
• Three track guards come standard for a
more durable undercarriage.
Integrated Idler and Adjuster
The front idler and adjuster cylinder
have been integrated in the new ZAXIS-6,
improving their durability.
Due to this integration, the bracket that
had supported the adjuster cylinder is
no longer required, resulting in less mud
buildup.
Reinforced idler bracket with slanted side frame
The side frame of the idler bracket is
slanted on both sides, which enlarges
the cross-sectional area of the external
surface of the idler bracket.
Reinforced undercarriage and increased crossbeam size and strength increase durability.
The design of the idler bracket has
been improved to make it easier to
remove mud.
