6/26/08 11:57:52 PM
More production, less fuel consumption
Increased Production
New E-mode
A combination of the hydraulic system
(HIOS*III) and new OHC** 4-valve engine allows the efficient use of hydraulic
pressure to increase speeds of actuators and boost production with higher
fuel efficiency. The productivity is
increased with 17% in comparison to
previous model ZAXIS-1.
The new E mode, H/P mode and
P mode can be selected to suit job
needs. The new E mode can save fuel
consumption 10% more than the
previous P mode, while yielding similar
production.
Increase in Swing Torque and
Digging Force
*Human & Intelligent Operation System
Swing torque and digging force are
increased significantly.
- Swing torque 10% UP
- Digging force 14% UP
Travelling High Power Mode;
At climbing or steering, when the
machine needs more travel speed, the
engine power automatically increases
which makes the machine faster.
**OverHead Camshaft
Efficient hydraulic control - HIOS III
ZAXIS-1 adapted HIOS II hydraulic
system that is suitable for fine controllability by the operators. Continuously
HITACHI developed new advanced hydraulic technology HIOS III for ZAXIS-3.
In addition to the fine controllability this
new system increases the efficiency of
hydraulic circuit and increases speed of
actuators.
The Hydraulic Boosting System
Enhanced Boom Recirculation System
In arm roll-in and boom-raise operation,
excess pressure oil is delivered
from boom cylinder rod side to arm
cylinder bottom side to increase flow
rate for higher arm roll-in speed with
20%. Excess pressure oil from boom
cylinder rod side is delivered to arm cylinder bottom side through a
regenerative valve to increase flow rate
for productive operation.
In combined operation of boom and
arm, pressure oil from boom cylinder
bottom side is delivered to boom cylinder rod side, assisted by boom weight,
for boom lowering. At the same time,
pressure oil from the pump is delivered
to the arm cylinder for arm movement.
This mechanism allows an increase of
speed in combined operation of 15%.
Development concept of new engine
OHC 4-Valve Engine
The new OHC 4-valve diesel engine is
developed and built to comply with the
rigorous Emission Regulations enforced
in 2006 in EU. This new engine contributes to environmental preservation. At
the same time it realizes high durability
and low fuel consumption by adapting
the latest advanced engine technology.
Common Rail Type Fuel Injection
System
Electronic control common rail type fuel
injection system drives an integrated
fuel pump at an ultrahigh pressure to
distribute fuel to each injector per
cylinder through a common rail.
This enables optimum combustion to
generate big horsepower, and reduce
PM* (diesel plume) and fuel
consumption.

A New Standard in Operator Comfort
The operator's seat of the ZAXIS-3 series gives the operator
an excellent view of the jobsite. On the widescreen colour LCD
monitor the operator can see what is behind the machine. Ample
legroom, short stroke levers and a large seat ensure optimum
working conditions for the operator during long hours.
ReviseKS-EN002EUR.indd 6
6/26/08 11:58:30 PM
The ZAXIS-3 series cab has been
redesigned to meet demands of
European customers. From the
operator’s seat the operator has an
excellent view of the jobsite. On the
widescreen colour LCD monitor the
operator can see machine conditions
and with the rear view camera, what is
behind the machine. Ample legroom,
short stroke levers and a suspension
seat with heating ensure optimum
working conditions. The seat features
horizontal, vertical and weight
adjustments and has a backrest
contoured for comfort, with
a HITACHI logo.
Wide adjustable armrests and a retractable seat belt are included. Short stroke levers
mean fingertip control of hydraulics and allow for continuous operation with less
fatigue. Three switches on the lever (optional) can be set to operate attachments other
than buckets. The cab is pressurized to keep out dust. Noise and vibrations are kept
to a minimum due to the elastic mounts, filled with silicone oil, the cab rests on.
Visibility is improved especially for the right downward view. A large overhead window
allows natural light to enter the cab. Sliding windows on the front and side enable
direct communication between operator and other workers. Foot space has increased
and breaker pedals have been redesigned for easier operation. A flat floor allows for
easy cleaning. Ergonomic controls and switches, fully automatic air conditioner and
a radio complete the package.
ReviseKS-EN002EUR.indd 7
6/26/08 11:58:53 PM
Embedded Information Technology
The ZAXIS-3 series is equipped with a widescreen colour LCD
monitor with adjustable contrast for day and night shifts. With
the monitor the operator can check maintenance intervals,
select work modes, monitor fuel consumption, and connect to
the rear-view camera. A theft deterrent system and multilanguage selection is also available.
Multi function monitor
Attachement support system
(work mode selector)
The colour LCD monitor, located in the
cab, indicates coolant temperature,
fuel level, and maintenance data. It also
allows one-touch adjustment of the
attachment. The display can also be
adjusted to day or night shift.
Maintenance support
When replacing the attachment, oil flow
adjustment can automatically be done
by one touch on the work mode
selection display on the LCD monitor.
Minor adjustments of oil flow is
possible if necessary.
Multilanguage selection
Replacement timing of hydraulic oil
and fuel filters is alerted to the operator
through the LCD monitor according to
the schedule preset by the user each
time when turning the key switch.
The scheduled maintenance can
prevent the failure of the machine.
The monitor enables you to select
12 European languages.
ReviseKS-EN002EUR.indd 8
6/26/08 11:59:09 PM
Rear view camera
Theft deterrent system
The electronic immobiliser requires
the entry of an encryption code to the
multifunctional monitor each time when
starting the engine to prevent theft and
vandalism.
The widescreen colour LCD can also
provide a view to the rear of the
machine. Enhanced safety during
swinging and travelling is the key
advantage.
The rear view camera, which is located
on the counterweight, can be switched
on manually using the selection switch
on the monitor. In addition, this feature
is automatically activated during
machine travel.
Fuel consumption monitoring
Fuel consumption per operating hour is
computed, and the result is displayed
on the LCD monitor. This information
suggests refuelling timing, and guides
energy-saving operation and efficient
job management.

A Solid Base for a Long Life
HITACHI’s technology is built on a wealth of experience and
know-how from limestone sites and quarries around the world.
The undercarriage of the ZAXIS 280 has become much stronger.
Improved construction and enlarged box sections, a track
undercover plate that protects the center joint and hydraulic
hoses make this machine more durable.
10
ReviseKS-EN002EUR.indd 10
6/26/08 11:59:38 PM
Strengthened undercarriage
The X-beam is strengthened by the
improved construction and enlarged
box sections. The section is increased
in strength up to 35%. Top and bottom
plates of the X-beam use monolithic
plates, instead of conventional welded
four plates. This eliminates welding to
strengthen the X-beam. Upper and
lower rollers and upper roller brackets
are increased in size for higher
durability. Track links are thickened and
reshaped for higher durability and
rigidity.
Improved idler brackets
The idler bracket reinforcing plate is thickened greatly for higher durability to prevent
the opening of idler bracket. The track link disengagement preventive plate, located
just behind the idler bracket, is thickened for higher durability, and reshaped by
extending its stepped end to prevent the disengagement of track links.
Strengthened front attachment
The boom top bracket is strengthened by using high-tensile steel.
At arm-bucket joint, the arm top is hardened with Tungsten-Carbide thermal
spraying for greater wear resistance at its contact surface with bucket, reducing
jerking. Reinforced resin thrust plates designed to reduce noise and resist wear.
The new HN bushings, containing HITASOL (solid molybdenum-based lubricant), are
utilized at the boom-arm joint and arm cylinder mounting area for better lubrication
and higher durability. (At other joints, conventional HN bushings are also utilized.)
The boom foot is enlarged for higher strength. This improvement increases the
durability and reliability under heavy-duty operation.

Simplified Maintenance
The ZAXIS-3 series meet customer demands for simplified
maintenance. Regular maintenance is the key for keeping
equipment in top condition, which can help to prevent costly
downtime. In addition, a regular serviced machine has higher
residual value. There are many service features to be found on
the ZAXIS-3 series.

Conveniently located inspection points
Wide doors give access, from ground level, to the fuel filter, water separator and
engine oil filter. A large handrail, steps and anti-skid plates lead to the engine cover.
The engine oil pan is fitted with a drain coupler. When draining, an associated drain
hose is connected to the drain coupler. The drain coupler is reliable, avoiding oil
leakage and vandalism.
The fresh air filter for the air conditioner
is relocated to cab door side from
conventional location behind the
operator seat. This allows easy cleaning
and replacement of the fresh air filter,
like the air circulation filter inside the
cab.
Parallel arrangement of the cooling pack
Easy removal of
debris and dirt
from blower, etc.
Engine
Oil Cooler
The oil cooler, radiator and intercooler are laid out in a parallel arrangement, instead
of the conventional in-line arrangement. This parallel arrangement is significantly
easier to clean around the engine. The air conditioner condenser can be opened for
easy cleaning of the condenser and the radiator located behind.

Safety Features
Ensuring the safety of the operator and other workers on the
jobsite is an important concern for HITACHI. That is why the
ZAXIS-3 series has a number of safety features including
a new reinforced cab and shut-off mechanisms for engine and
pilot controls.
CRES II cab
The CRES II cab is designed to help with “just in case” protection for the operator.
Safety in case of tipping is improved. The cab top, for instance, can withstand
about 4 times conventional load when side load is applied to the cab top until its
deformation reaches 200 mm.
Withstanding load : 4-fold increase
Additional features
Cab right guard
Evacuation hammer
Engine shut-off switch
Pilot control shut-off lever
FOPS guard
Retractable seat belt
(optional)
Other features include a retractable seatbelt, evacuation hammer and emergency
engine shut-off switch. A shut-off lever for pilot control helps to prevent unintentional
movements. In addition a Falling Object Protective Structure (FOPS) guard is
optionally available. For the cab windows there is a choice of laminated or tempered
glass.

Environmental Features
HITACHI takes its responsibility when it comes to the environment. Our production facilities have ISO 14001 certification.
The HITACHI machine is lead free and has a low-noise design,
therefore HITACHI customers get one of the most environmentally considerate hydraulic excavators available today.
A cleaner machine
The ZAXIS-3 series is equipped with a clean but powerful engine to comply with
Stage III A. An engine emission regulations effective in the European Union from
2006. Exhaust gas is partly re-combusted to reduce particulate matter (PM) output
and lower nitrogen oxide (NOx) levels.
A quieter machine
A number of features make this machine quieter. First, isochronous control of the
engine speed means a restriction of engine speed during no-load and light-duty
operation to suppress sound. A fan with curved blades reduces air resistance and
air flow noise. Third, a time-tested muffler suppresses engine noise significantly and
reduces emissions.
A recyclable machine
Over 97% of the ZAXIS-3 series can be recycled. All resin parts are marked to
facilitate recycling. The machine is completely leadfree. The radiator and oil cooler
are made from aluminium and all wires are lead-less. In addition, biodegradable
hydraulic oil is available for jobsites where special environmental care is required.
