3.1 General
The documentation of the workshop manual has
been created based on the engine available at the
time of going to press.
There may be deviations in the descriptions, illustra
tions and parts due to further developments.
The valid documentations published by DEUTZ AG
(for example Technical Circulars, Service Bulletins,
etc.) must be observed.
The maintenance work described in the operation
manual and in the workshop manual must be carried
out on schedule and completely. The maintenance
personnel must have the necessary technical
knowledge to perform the work. Safety and protec
tion devices which are removed during maintenance
work must be replaced again afterwards.
Caution!
The rules for the prevention of accidents and the
safety regulations must be observed during mainte
nance work.
Reference is made in the workshop manual job
cards to the regulations in chapter 3.2. These must
be read before working on the engine and must be
strictly followed.
The maintenance intervals and the work to be per
formed are specified in the maintenance schedule
of the operation manual. The job cards contain tech
nical documentation on the execution of mainte
nance work.

3.2 Specifications
3.2.1 Accident prevention and safety regula
tions
-
-
-
-
The legally prescribed rules for the prevention of ac
cidents must be observed. These are available from
professional associations or from dealers. These
are dependent on the application site, operating
mode and the operating and auxiliary materials be
ing used.
Special protection measures are specified depend
ing on the work being carried out, and are identified
in the job description.
Among other things it generally applies that:
● for the personnel:
– Only briefed personnel may operate or main
tain the engine. Unauthorised persons are
prohibited access to the machine room.
– Wear close-fitting clothing and ear protectors
in the machine room when the engine is in op
eration.
– Only deploy trained personnel to do repairs
and maintenance work.
– Do not work on the fuel system when the en
gine is running. The fuel system is under high
pressure - danger of death.
– Go to the workshop immediately in case of
leaks in the fuel system.
● for the engine room:
– Ensure adequate ventilation (do not cover air
shafts).
– Provide first aid kit and suitable fire extinguish
ers. Check the filling and readiness for opera
tion regularly.
– Only store inflammable materials in the ma
chine room if they are essential for operation
of the system.
– Smoking and naked flames are prohibited in
the machine room.
● for operation, maintenance and repairs on the
engine:
– The common rail systems used work with op
erating pressures up to
approximately 2000 bar. In the case of poten
tial faults, the pressure can even rise to signif
icantly higher values before the pressure
reducing valve opens.
– After shutting down the engine, wait at least
30 seconds before performing work on the fuel
system.
Depending on the version of common rail sys
tem, the fuel pressure in the common rail sys
tem will still not have dissipated after 30
seconds. The fuel pressure can permanently
be several 100 bar.
DEUTZ enginesSafety information / User information
The fuel pressure here does not drop until the
fuel system is opened and the fuel can es
cape.
– Only start the engine when all the protective
devices have been fitted. Make sure no-one is
standing in the danger area.
3
– Cleaning, maintenance and repair work may
only be performed with the engine at a stand
still and secured against starting.
– Fuel lines, injection lines or fuel high-pressure
lines must never be disconnected when the
engine is running.
– Danger of injury !
The fuel jet can deeply penetrate the skin.
– Do not come close to the leakage area in the
fuel high-pressure system with any body parts
(for example hand).
– Always carry out an exact visual inspection of
all high-pressure carrying components before
tests on the running engine. Wear suitable
protective clothing (for example goggles,
gloves) for this. Leakages entail potential haz
ard sources for the workshop personnel.
– Even if no leakages can be discerned in the
fuel high-pressure system, the workshop per
sonnel should avoid the direct hazard zone or
wear protective clothing (for example goggles,
gloves) during tests when the engine is run
ning and during the first test run.
– Always stay out of range of a fuel jet, as it
could cause severe injury.
– Fuel lines, injection lines and high-pressure
lines must not be deformed.
– Damaged fuel lines, injection lines and high-
pressure lines must be replaced.
– Smoking is strictly prohibited when working on
the fuel system.
– Do not work near to sparks and flames.
– Never disconnect an injector when the engine
is running.
– Loosen screw connections slowly and not
abruptly
– Open screw connections on the fuel system
with extreme caution.
– After all work on the fuel system, it must be
bleeded - see the operation manual, chapter
"6 Fuel system“.

3.2.2 Cleanliness instructions and measures
for working with common rail systems
The common rail systems used in DEUTZ engines
comprise high-precision components subjected to
extreme loads. In view of the high-precision technol
ogy, ensure utmost cleanliness when working on
the fuel system.
-
Notes and measures to be observed before starting
work on the fuel system
● The fuel system must be closed. Make a visual
inspection for leaks / damage to the fuel system.
● Clean the whole engine and engine room with the
system closed before starting work on the fuel
system.
● The engine must be dry when you start working
on the fuel system.
● Blowing (dry) with compressed air is only permis
sible with the fuel system closed.
● When using a steam jet, first cover up the control
unit, the cable plugs, all other electrical plug con
nections and the generator. Also, the steam jet
may not be pointed directly at them.
● Electrical plug connections must be plugged
when spraying.
● Remove loose parts (for example paint chips
from assembly work) with an industrial vacuum
cleaner or other suction device. Only suction may
be used in assembly work on the open fuel sys
tem.
● Only work on the fuel system in a clean environ
ment (no dust, no grinding or welding). Avoid
draughts (dust). Clean the workshop floor regu
larly. No brake or performance test benches may
be kept or operated in the same room.
● Air currents which kick up dust, such as those
caused by brake repairs or the starting of en
gines, should be avoided.
● For work such as removal and installation on de
fective hydraulic components on the Common
Rail System it is recommended to partition off a
separate workshop area in the factory. This must
be separate from other areas in which general
vehicle repairs such as brake repairs are carried
out.
● No general machine tools may be operated in
this room.
● Regular cleaning of the workshop area is manda
tory. Draughts, ventilation systems and heating
fans should be minimised.
● Areas of the engine room from which particles of
dirt could be loosened (for example the bottom
part of the tipped driver cab) must be covered
with fresh clean film.
● Working materials and tools must be cleaned be
fore work. Only use tools without damage to the
chrome plating or tools which are not chromeplated.
Notes and measures to be observed during work on
the fuel system or with the fuel system open.

SCR (Selective Catalytic Reduction)
● AdBlue® is a caustic medium which causes
heavy corrosion damage when it comes into con
tact with electronic components or similar.
● Leaks on the AdBlue® pipes, the tank, the supply
module and the feeding unit must be fixed imme
diately to avoid leakage of AdBlue®.
● Make sure the room is well ventilated.
● Contact with the skin should be avoided. Wear la
tex gloves if possible.
● Wash hands thoroughly before taking breaks and
at the end of shifts.
● If the substance comes into contact with eyes,
rinse thoroughly with water.
● If swallowed, rinse out mouth with a lot of water,
drink plenty of water and seek medical advice.
● If discomfort or illness continues, seek medical
advice.
● Product can pose danger of slipping if spilled. It
is essential to remove spilled liquid. In so doing,
ensure that the liquid does not enter the sewage
system or ground/surface water. This means that
the contamination should be physically removed
and disposed of in suitable containers. Minimal
amounts of remaining liquid may be rinsed away
with a lot of water.
● The so-called lag time is application-dependent
and may be up to 2 minutes in engines with an
SCR system because the SCR pipes have to be
pumped empty in this time.

3.3 Operation manual and workshop man
ual
In order to structure the information layout in a userfriendly way, the service documentation is divided
into operating instructions and job cards (workshop
manual).
The operation manual contains a general descrip
tion and instructions for all other maintenance work.
It contains the following chapters:
1. Contents, General
2. Engine description
3. Operation
4. Operating media
5. Maintenance
6. Care and maintenance work
7. Faults, causes and remedies
8. Engine conservation
9. Technical data
10.Service
The use of job cards (workshop manual) presuppos
es knowledge of the operating instructions content,
this applying in particular for the service specifica
tions. Repairs to the engine and components are
described in the job cards (workshop manual), for
the implementation of which more effort and corre
spondingly qualified experts are required.
-
-
-
3.4 Job cards
The job cards are differentiated into "W" and "I" job
cards.
The "W" job card documents the standard repairs to
the engine and/or its components. The necessary
tools and special tools are also indicated in the "W"
job card.
The "I" job card also documents corresponding
workflows for repairing the engine and/or its compo
nents. Special prerequisites must be fulfilled by the
workshops for implementation of these workflows.
For example, special tools and machine tools must
be available.
