ECONOMY AND
PRODUCTIVITY
Six cylinder Tier 3A compliant engine utilises electronic control to
optimise performance while minimising fuel consumption, lowering
running costs and boosting operating revenues.
Power to perform, environmental responsibility.
LOWERING
OWNERSHIP
COSTS
Extended service intervals, ultra-clean
hydraulic filters and easy service
access cut downtime.
Reduced maintenance, increased
productivity.
RAPID
PERFORMER
Twin main pumps offer the hydraulic power to get the
job done. Maximum bucket force of 470kN and arm
force of 347kN with auto power up provide the
breakout for the toughest site conditions.
Designed to perform, whatever the task.
OPERATOR
RESPONSE
Four operating modes match the engine and hydraulic
performance to the application. Revolutionary auto
setting uses Intelligent Computer Command Control
System (ICCCS) to instantly change between modes,
offering rapid response. Auto power boost increases
power for maximum breakout.
Instant power, total control.
WORKING ENVIRONMENT
Case operators benefit from superb cab comfort. Climate control, high levels of visibility and isolation
mountings make the CX800 the best office on site.
Comfortable operator, productive operator. 3
RAPID
MOVEMENT
Two speed tracking provides speed and
gradeability. Oiled track roller bearings
reduce heat build up, increasing track life.
Variable track width provides stability for
heavy digging.
Strong foundations, sturdy build.
POWER TO
PERFORM
Structural integrity of work equipment
offers high breakout forces with a range
of boom and dipper arm configurations.
Designed to work, built to last.
REGULAR
MAINTENANCE
Wide opening service panels, with walkways to
both sides of the machine, allow excellent levels of
service access to engine and hydraulic components.
Fan reverse clears debris from the cooling pack
on engine start-up. On-board diagnostics monitor
machine systems.
Serviceability, reliability, durability.
EXTENDED HOURS
1000 hour greasing on boom and arm pins (except bucket). EMS chrome plated pins and brass
bushes offer durable solution. 
Minimum downtime, maximum productivity.
BUILT TO LAST
Increased strength from top to bottom. Slew bearing
hub extends through top plate for added rigidity.
Track guards and strut-type chain links reduce
twisting and point loading.
Heavy duty design, heavy duty construction. 4
The CX800 enables the operator to have a choice on how the
machine is operated. Simply choose the work mode that matches
the machine output to the job application.
Four operating modes are available.
H Mode (Heavy)
For heavy excavation or whenever you need extra power.
S Mode (Standard)
For standard digging and loading operations reducing fuel
consumption.
L Mode (Light)
For lifting and other operations that need fingertip accuracy.
Auto-Mode
The most revolutionary approach to maximizing power & fuel
efficiency available today. Just select the Auto-Mode with the
switch panel. Using actual working pressure readings, ICCCS
instantly changes modes assuring the best combination of speed
and power while you can stay focused on the work at hand.
The Case CX800 is equipped with a proven Isuzu AH-6WG1X
diesel engine, providing 495 hp (369 kW) of power at an unstressed
1800 rpm. With high pressure common rail fuel injection, this
electronically-controlled engine meets the requirements of the
EU directive 97/68/EC Tier 3A on engine emissions.
The Case Intelligent Computer Command Control System (ICCCS),
working with electronic engine control, optimises the fuel injection
to meet the load on the engine and hydraulic cylinders. This
results in a high level of responsiveness for the operator and
more efficient use of the engine, reducing fuel consumption and
engine emissions.
The engine incorporates an automatic warm-up system, which
increases engine speed gradually as the correct operating
temperatures are reached, preventing premature wear of engine
components.
ENGINE
Case excavators offer the power and speed to perform, whatever
the application. Using an Intelligent Computer Command Control
System (ICCCS), the CX800 provides the optimum balance of
speed, power and fuel efficiency to meet the operators needs.
Boom priority permits faster cycle times in loading operations
as the hydraulic oil is prioritised to the main boom circuit during
the raise function. The energy created by oil returning from the
boom and the dipper arm is regenerated to increase the
excavating speed.
In addition there is an auto power boost function which automatically
increases the system pressure by 8-10 per cent to power through
heavy ground, or to help with heavy lifting duties.
The CX800 features an ultra-clean 1 micron hydraulic filter,
which provides an exceptional level of filtration, even removing
water from the oil. This results in extended hydraulic oil life, with
change intervals now set at 5000 hours, reducing downtime
and cutting operating costs.
HYDRAULIC SYSTEM
OPERATING MODES 5
OPERATORS CAB
As befits a range-topping machine, the CX800s cab offers high
levels of comfort, low noise and a climate-controlled working
environment. The entire cab is mounted on six shock absorbing
rubber and fluid mounts, reducing vibration and noise in the cab
for the operator. 
A fully adjustable suspension seat is standard equipment, offering
height, reach and rake options to ensure that all sizes of operator
can find their ideal working position. Automatic climate control
maintains the desired temperature in the cab whatever the
weather outside.
The cab is a full 1 metre wide, with plenty of room for the operator
to store coats and bags out of the working area. Large windscreens
and side glazing, along with low bodywork to the rear of the machine,
provide excellent all round visibility from the cab. Rear view safety
mirrors are also included in the standard specification. 6
As the biggest machine in the Case range, the CX800 continues
a long tradition of durable, highly productive mining and heavy
earthmoving excavators. A modified X-style carbody is welded
internally for added strength, and the turntable bearing hub
extends down through the top plate of the carbody for additional
structural integrity.
The machine has two speed travel motors, with a top speed of
4.2 km/h, making it easy to reposition on site when necessary.
The track motors will downshift automatically when climbing,
and compact high torque final drives ensure traction on the
steepest grades.
There are large, wide opening doors to both sides of the machine,
making it easy for technicians to access the engine and hydraulic
componentry. The CX800 is equipped with a hydraulically-driven
cooling fan, which can be reversed on start-up to blow dust and
debris away from the excavators cooling pack.
The machine benefits from a 900 litre fuel tank, to maximise
working time. An auto-stop electric fuel pump is fitted as standard
to the machine, to reduce refuelling times and make life easier
for the operator.
All boom pins (except the bucket pins) are extended maintenance
system (EMS) chrome plated for increased hardness, with
lubricated brass bushings fitted through the boom and dipper.
Dust seals are double structured to prevent the ingress of dirt
and dust on site.
This combination makes it possible to extend lubrication intervals
on the boom pins to six months/1000 hours of operation, cutting
downtime and ensuring that the machine keeps working longer.

CX800 customers can choose from a variety of main booms and dipper arms to suit different applications, all of which are
constructed of heavy duty steel box section with internal baffles to increase torsional rigidity. Deep groove welding ensures
that the booms and arms can withstand the stress of high breakout forces, heavy lifting and attachments such as hydraulic
breakers, compactors, demolition shears and crushers.
With a choice of two main booms and four dipper sticks, along with a range of buckets from 2.4 m
