Your machine has been designed and built to the high-
est standards of quality. It conforms to all current
safety regulations. See "Official documents". However,
the risk of accidents can never be completely
excluded. That is why it is essential to observe ele-
mentary safety rules and precautions.
Read this manual carefully, paying particular attention
to the instructions concerning safety, operation and
maintenance so as to avoid the risk of injury while
operating or servicing the machine.
The standard attachments and tools of this machine
are designed to carry out all kinds of earthmoving and
rehandling operations. If you want to use this machine
to handle a load (pipes, culverts, formwork, etc.),
make sure that it is designed to carry out this kind of
work. For this type of application, the machine must be
equipped with safety valves, an overload indicator, a
load handling chart corresponding to the type of
machine and its attachment and a load fixing point. All
legal requirements must also be strictly observed.
Do not use this machine for any application or purpose
other than those described in this manual. If the
machine is to be used for work involving the use of
special attachments, accessories or equipment, con-
sult your CASE Dealer in order to make sure that any
adaptations or modifications made are in keeping with
the machine's technical specifications and with prevail-
ing safety requirements.
Any modification or adaptation which is not approved
by the manufacturer may invalidate the machine's ini-
tial conformity with safety requirements.
The machine must undergo regular inspections, the
frequency of which varies according to the type of use.
Consult your CASE Dealer.
The engine and fuel system on your machine is
designed and built to government emissions stand-
ards. Tampering by dealers, customers, operators and
users is strictly prohibited by law. Failure to comply
could result in government fines, rework charges,
invalid warranty, legal action and possible confiscation
of the machine until rework to original condition is
completed. Engine service and/or repairs must be
done by a certified technician only!
Before permitting a new operator on this machine,
make sure:
1. That the operator is qualified to operate the
machine correctly and safely.
2. That the operator has read and understood the
instructions given in this manual.
Always keep this manual in the operator's compart-
ment (in the seat back, behind the operator's seat).
Make sure it is always complete and in good condition.
If you wish to obtain extra copies, or copies in lan-
guages other than that of the country of use, consult
your CASE Dealer.
Your CASE Dealer is at your disposal for any further
information. He will also provide any after-sales serv-
ice you may require, and genuine CASE spare parts,
your guarantee of quality and match.

DESCRIPTION OF THE MAIN COMPONENTS
The CX225SR is a fully hydraulic excavator. It consists of an undercarriage fitted with tracks and a turntable bearing
which supports the upperstructure frame. The upperstructure frame supports the attachment, at the front end of the
machine, plus the engine, hydraulics and cab. When the operator works the controls, the engine-driven pump deliv-
ers hydraulic fluid to the control valves. The control valves distribute the hydraulic fluid to the various cylinders and
motors concerned. A cooling system maintains the hydraulic fluid at normal operating temperature.

SAFETY/DECALS/HAND SIGNALS
SAFETY INSTRUCTIONS
Your safety and that of people around you depends on
you. It is essential that you understand this manual for
the correct operation, inspection, lubrication and main-
tenance of this machine.
Read this manual carefully and check that:
- You understand fully the symbols on the controls
and the safety signs used in this manual and on the
machine.
- You understand fully the speed, stability, braking
and steering characteristics of the machine. If you
are in any doubt, consult your CASE Dealer.
The safety messages in this manual concern situations
which may arise during normal machine operation and
servicing. These safety messages also indicate the dif-
ferent ways of coping with these situations. Other
safety messages are used throughout the manual to
indicate specific dangers.
Whatever type of work is being done (earthmoving,
handling, etc.), the safety measures for private or pub-
lic work-sites are those which conform to current regu-
lations in the country concerned, or the type of
operation concerned (example: mining, quarrying, tun-
nelling).
The safety instructions given in this manual are a sum-
mary of the basic rules to be respected at all times and
do not exempt you from insurance requirements or
from abiding by the highway code.
Always keep this manual in the location provided for
that purpose (behind the operator’s seat). Make sure it
is always complete and in good condition. If you wish
to obtain extra copies, or copies in languages other
than that of the country of use, consult your CASE
Dealer.
