SERVICE ACCESS
The WX series of wheeled excavators use the latest Family III Case diesel engines. All engines feature extended
500 hour service intervals, for minimal downtime, and the machines have easy access to all service and diagnostic
points. An ecological oil drain reduces the risk of ground contamination during regular maintenance work.
Ease of service. Minimum downtime.
OPERATOR SECURITY
Large volume fully glazed cab features outstanding visibility all around the machine. An air suspension seat and tilting steering
column ensure that all operators can achieve a comfortable driving position, reducing fatigue and increasing productivity.
Automatically operating brakes and front axle lock, along with direction control switch on the joystick reduce operator effort,
while Digipower management and fine grading mode allow the operator total control of the engine and hydraulic power.
Reduced fatigue. Maximum productivity.

CASE PERFORMANCE
The WX machines have a compact upperstructure that promotes high lifting and digging performance. With full blade and
stabiliser independence, and mechanically lockable stabiliser pads, the WX excavators offer a solid working platform. High engine
output with Power Boost function ensures total productivity, while a PowerShift transmission allows optional travel speeds of
30 km/h with on-the-move gear shifting. Quick coupler compatible with previous generation machines and quick connectors on
auxiliary hydraulics provides rapid changeover between attachments, increasing machine versatility.
Designed to work. Built to perform.
SECURE OPERATION
Case inching and extra slow speed setting, along with road travel mode swing and attachment cut-out, provide safe operation
in all conditions. Engine safe warm-up control and automatic battery cut-off reduce the possibility of damage to the engine and
hydraulic system at start-up. Stabiliser cylinder protection cuts the risk of damage in rough ground and abrasive material.
Integrated anti-theft device provides peace of mind for Case WX customers.
Safety First. Investment Protection.

4
Large glass area with two-piece full height front windscreen
offers unparalleled visibility all around the machine. The operator
has a clear view to the work area when digging and loading, and
to the road ahead when travelling the machine between job sites.
A low engine canopy to the rear of the machine provides a clear
view behind the excavator when manoeuvring on confined sites.
The WX145 uses a four cylinder Case engine for maximum fuel
economy. This EU Tier III compliant engine is turbocharged and
intercooled for optimised clean combustion and high power
output. The engine has been designed for maximum reliability
and durability, with an auto warm-up feature ensuring long service
life and minimal downtime.
ENGINE
A two speed range transmission offers an optional maximum
travel speed between job sites of 30 km/h. Excellent ground
clearance, with the option of a two-piece drive shaft, offers true
off-road capability for maximum versatility on site. As with all
Case WX machines the WX145 has the Case inching control,
which allows the operator to gradually move the machine for
safe and accurate positioning. The machine is available with
single wheels or double wheels with a twinning ring, allowing the
customer to tailor the layout to meet their application.

OPERATOR’S CAB
Ergonomic design with large tinted glass area provides
feeling of space and excellent all round visibility,
ensuring safe operation on site. Large roof window
with shade, fully adjustable suspension seat, adjustable
tilt steering column and exceptionally low internal
noise levels allow fatigue-free operation and full day
productivity. Large LCD display provides all operating
information and diagnostic functions, along with
integrated working mode display. All major operating
controls, including travel direction, attachment and
blade/stabiliser selection, levelling mode and power
boost function are integrated into the joystick levers,
reducing operator effort and ensuring total control
of the machine.

6
Even with the reduced tail radius of the Case WX, the machine
retains the Case access catwalk behind the cab, offering the
service engineer excellent access to the regular service and
maintenance points and providing a safe working area. A lift up
engine canopy provides a clear view to the top of the engine, the
hydraulic valves and the cooling pack.
Clean, easy to maintain hydraulic valve layout. The Case Digipower
hydraulic control system monitors the main pumps and regulates
engine power to meet the needs of the operator. The WX
machines offer a range of selectable power levels, for specific
digging and lifting tasks, including a levelling mode for fine grading
work. PowerBoost is standard in the lifting modes and works for
8 seconds in all other modes on request.
HYDRAULICS
Customers can choose between a stabilisers, blade or a
combination of the two, thanks to the modular design of the Case
WX chassis. The stabilisers and dozer blade are independently
controlled, to allow for levelling on rough ground. Optional City
stabilisers have numerous pad positions, providing full stability
with the ability to work the machine in confined areas, such as
alongside kerbs and raised ironwork.
