Environmental responsibility
Scania has always been very much at the leading edge when it comes to
developing and producing engines which are as environmentally friendly as
possible.
Major progress has been made on reducing harmful exhaust emissions as
required to be able to meet the stringent environmental standards stipulated
on almost all markets.
At the same time, we have been able to maintain high quality in terms of
performance and operating economy for Scania Industrial and Marine
Engines.
To preserve these qualities throughout the entire service life of the engine, it
is important for the operator/owner to follow the instructions on running,
maintenance and the choice of fuel and oil as outlined in the manual.
Other efforts to preserve the environment we all share are possible by
ensuring that the person carrying out servicing and maintenance always
makes sure that environmentally hazardous waste after servicing and repairs
(oil, fuel, coolant, filters, batteries, etc.) is dealt with and disposed of in
accordance with applicable environmental standards.
On a number of pages, this Operator’s Manual contains specially highlighted
text with instructions to help protect our environment during certain servicing
and maintenance work.
See example
Use a container to avoid spillage
when bleeding and changing
components.
Help protect our
environment!

Certified engines
Emissions-certified engines have been approved in accordance with a special
certification standard. The certified engines supplied by Scania meet the most
stringent emissions standards which apply on European (EU) and non-
European (USA) markets.
Scania guarantees that all the engines it supplies of a certified type are
equivalent to the engine approved for certification.
The engine comes with a special certification plate which indicates the
certification rules (standard) to which the engine has been approved. See
page 14.
The following is required for the certified engine to meet emissions standards
once it has been commissioned:
- Servicing and maintenance must be carried out in accordance with the
instructions in this manual.
- Only genuine Scania parts are to be used.
- Injection equipment is to be serviced by an authorised Scania workshop.
- The engine must not be modified with equipment not approved by
Scania.
- Seals may be broken and setting data edited only once approval has been
granted by Scania in Södertälje. Changes may be made by authorised
personnel only.
- Changes which affect the exhaust system and intake system must be
approved by Scania.
Otherwise, the instructions in the manual in respect of running, care and
maintenance of the engine shall apply. The safety precautions described over
the next four pages must also be observed.
Important!
If servicing and maintenance are not carried out as
specified above, Scania can no longer guarantee that the
engine will comply with the certified design, nor can it take
responsibility for any damage that occurs.

WARNING
!
11
Safety precautions for running the engine
Daily inspection
Always visually inspect the engine and engine
compartment before starting the engine and once
you have stopped the engine after running.
This will enable you to easily detect fuel, oil or
coolant leaks, or any other abnormalities which may
require rectification.
Refuelling
There is a risk of fire and explosion when refuelling.
The engine must be stopped and smoking is not
allowed.
Do not overfill the tank due to a risk of expansion,
and close the filler cap properly.
Use only fuel recommended in the service
literature. Fuel of the wrong quality can cause the
engine to malfunction or stop by preventing the
injection pump and injectors from operating as they
should.
This can cause damage to the engine and, possibly,
injury.
Hazardous gases
Only start the engine in a well ventilated area. The
exhaust fumes contain carbon monoxide and nitric
oxides, which are toxic.
If it is run in a enclosed space, there should be an
effective device to extract exhaust gases and
crankcase gases.
Starter lock
If the control panel is not fitted with a key operated
switch, there should be a lock on the engine room to
prevent unauthorised starting of the engine.
Alternatively, a lockable on/off master switch or
battery master switch can be used.
Starter spray
Never use starting spray or similar as a starting aid.
This can cause an explosion in the intake manifold
and possible injury
.
Running
The engine must not be run in environments where
there is a risk for explosion as all of the electrical or
mechanical components can generate sparks.
Approaching a running engine always poses a safety
risk. Parts of the body, clothes or dropped tools can
get caught in rotating parts such as the fan and cause
injury.
For personal safety all rotating parts and hot
surfaces must therefore be shielded as much as
possible.
12
Safety precautions for handling
materials
Fuel and lubricating oil
All fuels and lubricants and many chemicals are
flammable. Always follow the instructions on the
relevant packaging.
All work on the fuel system must be done with the
engine cold. Fuel leaks and spillage on hot surfaces
can cause fire.
Store soaked rags and other flammable materials
safely so as to avoid spontaneous combustion.
Batteries
The batteries contain and emit oxyhydrogen gas,
particularly during charging, and this gas is
flammable and highly explosive. There must be no
smoking, naked flames or sparks near the batteries
or the battery compartment.
Incorrect connection of a battery cable or jump lead
can cause a spark, which in turn can cause the
battery to explode.
Chemicals
Most chemicals such as glycol, corrosion inhibitors,
preservative oils, degreasing agents, etc. are
hazardous to health. Always follow the safety
precautions on the relevant packaging.
Some chemicals, such as preservative oil, are also
flammable.
Store chemicals and other materials which are
hazardous to health in approved containers, marking
them clearly and storing them where they are
inaccessible to unauthorised persons. Always hand
in leftover or used chemicals to an authorised waste
disposal contractor.
Safety precautions for care and
maintenance
Stop the engine
Always stop the engine before maintenance and
servicing unless stated otherwise.
Prevent unwanted starting by taking out the ignition
key where applicable and disconnecting the power
using the master switch or battery master switch and
locking them. Also put up a warning sign
somewhere appropriate, indicating that work is in
progress on the engine.
Working with a running engine always poses a
safety risk. Parts of the body, clothes or dropped
tools can get caught in rotating parts and cause
injury.
Hot surfaces and fluids
There is always a risk of sustaining burns when an
engine is hot. Therefore, take care not to come into
contact with manifolds, the turbocharger, the sump,
hot coolant and oil in pipes and hoses.
Lifting the engine
The engine lifting eyes must be used when lifting
the engine. Check first that your lifting devices are
in good condition and of the correct size to lift the
weight.
Extra equipment on the engine can alter the centre of
gravity, which is why you may need additional
lifting devices to balance the engine correctly and
lift it safely.
Never work underneath a suspended engine!
Batteries
The batteries contain a highly corrosive electrolyte
(sulphuric acid). Take care to protect your eyes, skin
and clothes when charging or handling batteries.
Wear protective gloves and goggles.
If the acid splashes on your skin, wash it off with
soap and copious amounts of water. If acid splashes
in your eyes, flush them immediately with copious
amounts of water and contact a doctor.
Dispose of used batteries through an authorised
waste disposal contractor.
13
Electrical system
The engine must be stopped and the power
disconnected using the master switch or battery
master switch before working on the electrical
system.
External power supplies to extra equipment on the
engine must also be disconnected.
Electric welding
When carrying out welding work close to and on the
engine, remove the battery leads and the cables to
the alternator. Also remove the multi-pin connector
to the control unit.
Connect the weld clamp to the component to be
welded and close to the welding point, never to the
engine or in such a manner that the current can pass
over to a mounting.
When you have finished welding, connect the cables
to the alternator and control unit before connecting
the batteries
.
Lubrication system
Hot oil can cause burns and skin irritation.
Therefore, avoid skin contact with hot oil.
Make sure that there is no pressure in the lubricating
system before starting work on it. Never start or run
the engine with the oil filler cap removed, as this
may cause oil to be thrown out.
Dispose of used oil through an authorised waste
disposal contractor.
Cooling system
Never open the coolant filler cap if the engine is hot.
Hot coolant or steam may spray out and cause burns.
If you have to open or remove a cooling system
component when the engine is hot, open the cap
very carefully and slowly to relieve the system
pressure before removing the cap. Wear gloves as
the coolant is still very hot.
Dispose of used coolant through an authorised
waste disposal contractor.
Fuel system
Always wear gloves when looking for leaks or
carrying out any other work on the fuel system. Also
wear protective goggles when testing injectors.
Fuel escaping at high pressure can penetrate tissues
and cause serious injury.
Never use non-genuine parts in the fuel and
electrical systems as genuine parts are designed and
manufactured to minimise the risk of fire and
explosion.
Before starting
Fit all removed shields before starting the engine
again. Check that you have not left any tools or other
objects on the engine.
Never start the engine without the air filter fitted.
There is a risk of objects being sucked into the
compressor impeller or of injury if you come into
contact with it.
14
Type designations
The engine type designation indicates engine type, size and applications in
code form.

EMS engine management
system
This engine has an electronic management system, EMS (Engine
Management System) with unit injectors (PDE) which provide each cylinder
with the right amount of fuel at the right time in all operating situations.
The EMS system consists of a control unit (S6) and sensors for speed, charge
air temperature and pressure, coolant temperature, oil pressure, accelerator
pedal/throttle actuation which constantly emit signals to the control unit.
With the aid of this input data and the programmed control software, the
correct fuel amount and correct injection time are calculated for each unit
injector under the specific operating conditions.
The EMS system sensors can also be used to emit signals to the instruments
in the instrument panel.
The control unit constantly checks the sensors to make sure they are
operational.
The control unit contains monitoring functions to protect the engine in the
event of a fault which would otherwise damage it. In the event of a fault, for
example alarm level for low oil pressure or high coolant temperature, the S6
control unit sends a CAN message to a coordinator.
The main task of the coordinator is to pass on data by means of CAN
communication from the engine control unit to other control units and signals
to gauges and lamps in the instrument panel. The coordinator also has
monitoring functions.
