3.2 Specifications
3.2.1 Accident prevention and safety regulations
The legally prescribed rules for the prevention of accidents 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 being used.
Special protection measures are specified depending on the work being carried out, and are identified
in the job description.
Among other things it generally applies that:
z 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 operation.
– 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.
z 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 operation 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.
z for operation, maintenance and repairs on the
engine:
– Wait 30 seconds after switching off the engine
before working on the fuel sytem.
– After all work on the fuel system, it must be
bleeded - see the operation manual, chapter
"6 Fuel system“.
– Only start the engine when all the protective
devices have been fitted. Make sure no-one is
standing in the danger area.
– Cleaning, maintenance and repair work may
only be performed with the engine at a standstill and secured against starting.
must never be connected when the engine is
running.
– Do not place hands near to a leak in the high
3
pressure fuel system.
– Also carefully check all high pressure compo-
nents visually before performing tests on the
running engine. Wear suitable protective
clothing (for example protective glasses).
Leaks are a potential source of danger for
workshop personnel.
– Even if no leaks are discernible on the high
pressure fuel system, the workshop personnel
should avoid the immediate danger zone or
wear suitable protective clothing (such as protective glasses) when performing tests on the
running engine and during the first trial run.
– Always stay out of range of a fuel jet, as it
could cause severe injury.
– 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.
3.2.2 Cleanliness instructions and measures for handling the DEUTZ Common Rail System
The DEUTZ Common Rail system used in the
DEUTZ engines consists of high-precision components which are exposed to extreme stress . Grea t
attention must be paid to cleanliness when working
on the fuel system due to the high precision technology.
Notes and measures to be observed before
starting work on the fuel system
z The fuel system must be closed. Make a visual
inspection for leaks / damage to the fuel system.
z Clean the whole engine and engine room with the
system closed before starting work on the fuel
system.
z The engine must be dry when you start working
on the fuel system.
z Blowing (dry) with compressed air is only permis-
sible with the fuel system closed.
z When using a steam jet, first cover up the control
unit, the cable plugs, all other electrical plug connections and the generator. Also, the steam jet
may not be pointed directly at them.
z Electrical plug connections must be plugged
when spraying.
z 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 system.
z Only work on the fuel system in a clean environ-
ment (no dust, no grinding or welding). Avoid
draughts (dust). Clean the workshop floor regularly. No brake or performance test benches may
be kept or operated in the same room.
z Air currents which kick up dust, such as those
caused by brake repairs or the starting of engines, should be avoided.
z 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.
z No general machine tools may be operated in
this room.
z Regular cleaning of the workshop area is manda-
tory. Draughts, ventilation systems and heating
fans should be minimised.
z 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.
z 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 s ystem ope n.
z Only work in clean overalls.
z Only lint-free cleaning cloths may be used for
work on the fuel system.
z 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 system.
z 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.
z Do not use used cleaning fluid or test fluid for
materials which can leave behind particles or fibres (cardboard, wood, cloths) may be used.
z Removed parts may only be rubbed down with
clean, lint-free cloths. No dirt particles may be
rubbed into the components.
z Openings on the components and on the engine
must be closed immediately with suitable stoppers/caps.
z The stoppers/caps may only be removed imme-
diately before installing.
z Store stoppers/caps free from dust and dirt in the
original packaging and dispose of after using
once.
z Only remove new parts from the original packag-
ing just before installation.
z Removed components must be kept in new, seal-
able bags or - if available - in the packaging of the
new parts.
z Always use the original packaging of the new part
to send back the removed components.
Notes and measures for the vehicle workshop
area
z For work such as removal and instal la tion 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 gener al
vehicle repairs such as brake repairs are carried
out.
z The workshop floor is sealed or tiled.
z No welding gear, grinders, general machine
tools, brakes or performance test benc he s ma y
be operated in this room.
z Regular cleaning of the workshop area is manda-
tory. Draughts, ventilation systems and heating
fans should be minimised.

Pay attention to utmost cleanliness when
working on the fuel system.
Remove residue paint and particles of dirt
before removing.
Clean the respective affected parts carefully. Blow damp areas dry with compressed air.
Observe the safety regulations and natio nal specifications for handling fuels.
Close all connections immediately after
opening with new, clean plugs/caps.
Do not remove plugs/caps until immediately before assembling.
Collect leaking operating substances in
suitable vessels and dispose of according
to regulations.
After all work on the fuel system, it must be
bleeded - see the operation manual, chapter "6 Fuel system“.
The measured compression pressure
depends on the starting speed during the
measuring process and the altitude of the
engine installation site. Therefore, limit
values cannot be determined exactly. The
compression pressure measurement is
only recommended as a reference measurement of all cylinders of an engine to each
other. If mor e than 15% deviation has been
determined, the cause should be determined by disassembling the cylinder unit concerned.
