Operating safety
G
WARNING
If you do not have the prescribed service/
maintenance work or necessary repairs car-
ried out, this could result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as necessary repairs car-
ried out at a qualified specialist workshop.
The operating safety of an engine system
depends on its professional installation in the
overall system (e.g. the vehicle or working
machinery). As the operator of the engine,
you also affect its safe operation.
Through compliance with the prescribed
maintenance intervals, you fulfil part of the
requirements for safe operation of the
engine.
However, safe operation of the engine also
depends upon its proper use and care. This
includes, for example, regularly checking the
oil level.
Safety precautions
Damage to the engine can also lead to per-
sonal injury. In order to avoid engine damage,
the following safety precautions must be
adhered to.
R
Only start the engine when the batteries
are firmly attached.
R
Do not disconnect the batteries when the
engine is running.
R
Do not use a rapid charger to start the
engine.
R
Only perform the jump-starting proce-
dure with separate batteries.
R
Note, the battery terminals must be dis-
connected when rapid charging the bat-
teries.
R
Observe the operating instructions of the
rapid battery charger.
R
Please note that the "+" and "-" terminals
on the batteries must be disconnected
when carrying out electric welding work.
R
The control unit connectors may only be
connected/disconnected when the elec-
trical system is switched off.
R
Incorrect control unit-power supply
polarity (e.g. by connecting up the bat-
teries incorrectly) can cause irreparable
damage to the control units.
R
Tighten diesel injection system connec-
tions to the prescribed tightening torque.
R
If temperatures above 80 † are to be
expected (e.g. in a drying oven), the con-
trol unit on the engine must be removed.
R
Only use the appropriate testing probes
when taking measurements from electri-
cal connectors (e.g. a Mercedes-Benz
connection set). Telephones and two-
way radio devices that are not connected
to an external aerial can cause malfunc-
tions in the electronics and thus endan-
ger the operating safety of the engine.
Warning stickers
If you remove any warning stickers, you or
others could fail to recognise certain dangers.
Various warning stickers are attached to the
engine system. Their purpose is to make you
and others aware of various risks.

WARNING
Modifications to electronic components, their
software as well as wiring could affect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any-
more and/or jeopardise the operational
