• Read the section on safety carefully.
• Get to know your engine so that you know
what it can do and how it works.
• Always contact an authorised Scania work-
shop for maintenance and repairs.
The information in this Operator's manual was
correct at the time of going to press. Scania re-
serves the right to make alterations without prior
notice.
Note:
Always use Scania spare parts for maintenance
and repair.
Certification
IMPORTANT!
For Scania to guarantee that the engine corre-
sponds to its certified configuration, and take re-
sponsibility for any damage and injuries that
occur, maintenance must be carried out in ac-
cordance with the instructions in this Operator's
manual.
An emissions certified engine fulfils the emis-
sions requirements for a particular range of ap-
plication.
On each emissions certified engine there is a la-
bel which shows which requirements the engine
fulfils. Scania guarantees that each such engine
fulfils the emissions requirements for the range
of application for which it is certified.
The following are required for the certified en-
gine to fulfil the emissions requirements once it
has been taken into service:
• Maintenance is to be carried out in accord-
ance with the instructions in this Operator's
manual.
• Maintenance and repairs of injection equip-
ment are to be carried out by an authorised
Scania workshop.
• The engine may only be modified with equip-
ment that has been approved by Scania.
• Seals may be broken and setting data edited
only once approval has been granted by Sca-
nia. Modifications may be made by author-
ised personnel only.
• Modifications affecting the exhaust and in-
take systems must be approved by Scania.
Otherwise, the instructions in the Operator's
manual for the running and maintenance of the
engine shall apply. Follow the safety precautions
on the following pages.

Environmental liability
Scania develops and produces engines that are as
environmentally-friendly as possible. Scania has
made major investments in the reduction of
harmful exhaust emissions in order to fulfil the
environmental requirements in force in almost
every market.
At the same time, we have been able to maintain
a high level of performance quality and operat-
ing economy for Scania engines. To maintain
these throughout the entire service life of the en-
gine, it is important for the user to follow the in-
structions on running, maintenance and fuel,
lubricating oil and coolant as outlined in the Op-
erator's manual.
Other green initiatives taken include ensuring
that, following maintenance and repair, waste
that is harmful to the environment (for example
oil, fuel, coolant, filters and batteries) is disposed
of accordance with the applicable environmental
requirements.
Information on parts with par-
ticularly hazardous substanc-
es

Environment and safety
Fuel
WARNING!
The wrong fuel grade can cause breakdowns or
stoppages by causing the injection system to
malfunction. This can cause damage to the en-
gine and, possibly, personal injury.
REQUIREMENT!
Use only fuel which fulfils the requirements in
the Quality requirements for fuel section.
Refuelling
WARNING!
During refuelling there is a risk of fire and explo-
sion. The engine must be switched off and smok-
ing is prohibited.
Never overfill the tank as the fuel needs space to
expand. Make sure that the filler cap is fully
closed.
Hazardous gases
WARNING!
Only start the engine in a well-ventilated area.
The exhaust gases contain carbon monoxide and
nitrogen oxides, which are toxic.
When the engine is run in an enclosed space,
there must be an effective device to extract ex-
haust gases and crankcase gases.
Starter lock
IMPORTANT!
If the instrument panel is not fitted with a starter
lock, the engine compartment should be locked
to prevent unauthorised personnel from starting
the engine. Alternatively, a lockable master
switch or battery master switch can be used.
Starter gas
WARNING!
Never use starter gas or similar agents to help
start the engine. This can cause an explosion in
the intake manifold and possible injury.
Driving
WARNING!
The engine must not be run in environments
where there is a risk of explosion, as all of the
electrical or mechanical components can gener-
ate 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 ro-
tating parts and hot surfaces must be fitted with
guards.

OPM 350 en-GB 10

Environment and safety
Safety precautions for handling ma-
terials
Fuel and lubricating oil
WARNING!
All fuels and lubricants as well as many chemi-
cals are flammable. Always follow the instruc-
tions on the relevant packaging.
The work must be carried out on a cold engine.
Fuel leaks and spillages on hot surfaces can
cause fire.
Store used rags and other flammable materials
safely so as to avoid spontaneous combustion.
Batteries
WARNING!
The batteries contain and form oxyhydrogen gas,
particularly during charging. Oxyhydrogen gas
is flammable and highly explosive.
There must be no smoking, naked flames or
sparks near the batteries or the battery compart-
ment. Incorrect connection of a battery cable or
jump lead can cause a spark, which can cause the
battery to explode.
Chemicals
WARNING!
Most chemicals such as glycol, anti-corrosive
agents, preservative oils and degreasing agents,
are hazardous to health. Some chemicals, such as
preservative oil, are also flammable. Always fol-
low the safety precautions on the packaging.
Store chemicals and other materials which are
hazardous to health in approved and clearly
marked containers, where they are inaccessible
to unauthorised persons.
Environment
Excess and used chemicals must be disposed of
as specified in national and international laws
and regulations.
Reductant
Reductant (AdBlue®, DEF, ARLA 32 eller
AUS 32/AUS 40) is used in the reductant tank
for engines fitted with an SCR system.
The reductant is not toxic, but it is still important
to observe the following when working on the re-
ductant circuit:
• If reductant comes in contact with the skin:
Wash with soap and plenty of water.
• If reductant splashes in the eyes: Rinse imme-
diately using an eye bath and then seek med-
ical attention.
• Change clothes if they have been spilled on.

OPM 350 en-GB 11
© Scania CV AB 2023, Sweden
Environment and safety
REQUIREMENT!
Use only reductant which fulfils the require-
ments in the Reductant with SCR section.
Safety precautions for maintenance
Switch off the engine
WARNING!
Working on 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.
Always switch off the engine before carrying out
maintenance, unless otherwise indicated.
Make it impossible to start the engine: Remove
any starter key, or cut the power using the main
power switch or battery master switch and lock
them.
Fix a warning plate somewhere appropriate,
showing that work is being carried out on the en-
gine.
Hot surfaces and fluids
WARNING!
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are branch
pipes, turbochargers, oil sumps, and hot coolant
and oil in pipes and hoses.
Lubrication system
WARNING!
Hot oil can cause burns and skin irritation. Wear
protective gloves and eye protection when
changing hot oil.
Make sure that there is no pressure in the lubri-
cation system before starting work on it.
Make sure that the oil filler cover is fitted when
starting and driving in order to avoid oil escap-
ing.
Environment
Used oil must be disposed of as specified in na-
tional and international laws and regulations.
Cooling system
WARNING!
Never open the coolant filler cap when the en-
gine is hot. Hot coolant and steam may spray out
and cause burns. If the cap has to be opened do it
slowly to release the pressure before removing
the cap. Wear protective gloves as the coolant is
still very hot.
Avoid skin contact with coolant as this may
cause irritation to the skin. Wear eye protection
and gloves when handling coolant.
Ethylene glycol can be fatal if ingested.
Environment
Used coolant must be disposed of as specified in
national and international laws and regulations.

OPM 350 en-GB 12

Environment and safety
Fuel system
WARNING!
Maintenance and repairs of injection equipment
are to be carried out by an authorised Scania
workshop.
Always use Scania spare parts for the fuel and
electrical systems. Scania spare parts are de-
signed to minimise the risk of fire and explosion.
Environment
Use a suitable container. The fuel collected must
be disposed of as specified in national and inter-
national laws and regulations.
SCR system
IMPORTANT!
Cleanliness is very important when working on
the reductant circuit. Clean thoroughly around
all parts to be dismantled to prevent dirt from en-
tering the system.
When working on the SCR system, the reductant
connections may only be lubricated with aque-
ous soft soap solution or with distilled water with
a 3% urea mixture. Any other types of lubricant
may block and damage components in the SCR
system.
Reductant causes certain metals to corrode. Al-
ways rinse away reductant spillage on connec-
tions and other parts with lukewarm water to
prevent corrosion. If reductant seeps into electri-
cal connections or electrical cables, these must
be renewed.

OPM 350 en-GB 13

Environment and safety
Electrical system
WARNING!
Switch off the engine and switch off the power
by disconnecting the electrical cables to the bat-
tery. External power supplies to extra equipment
in the engine must also be disconnected.
Always use Scania spare parts for the fuel and
electrical systems. Scania spare parts are de-
signed to minimise the risk of fire and explosion.
Electric welding
WARNING!
When carrying out welding work on and near the
engine, disconnect the battery and alternator
leads. Pull out the multi-pin connector for the en-
gine control unit as well.
Connect the welding clamp close to the compo-
nent to be welded. The welding clamp must not
be connected to the engine, or so that the current
can cross a bearing.
When welding is finished:
1. Connect the alternator and engine control
unit cables.
2. Connect the batteries.
Batteries
WARNING!
The batteries contain highly corrosive sulphuric
acid. Take care to protect your eyes, skin and
clothes when charging or handling batteries.
Wear protective gloves and eye protection.
If sulphuric acid comes in contact with the skin:
Wash with soap and plenty of water. If it gets in
your eyes: Rinse immediately with plenty of wa-
ter and seek medical attention.
Environment
Used batteries must be disposed of as specified
in national and international laws and regula-
tions.
Before starting
WARNING!
Ensure that all guards are in place before starting
the engine. Ensure that no tools or other objects
have been left on the engine.
The air filter must be fitted before starting the en-
gine. Otherwise there is a risk of objects being
sucked into the compressor impeller or of injury
if you come into contact with the air filter.
Cybersecurity
IMPORTANT!
The machine manufacturer is responsible for en-
suring that all engine management communica-
tion is protected against all forms of cyber attack.
The machine manufacturer is also responsible
for ensuring the engine can be operated safely in
all conditions, including the option of shutting
off the engine in the event of disruption to com-
munications with or without engine control.

ronmental Protection Agency regulations:
1. Fuel system
2. Air-induction system
a) Intake manifold
b) Turbocharger system
c) Charge air cooler system
3. Exhaust manifold
4. Combustion chamber
a) Piston
b) Cylinder head
5. Crankcase ventilation
6. Sensors
a) Engine speed sensors
b) Oil pressure sensor
c) Coolant temperature sensor
d) Coolant level sensor
e) Charge air pressure sensor
f) Charge air temperature sensor
7. Electronic control unit
8. Components used in the above mentioned
systems
IMPORTANT!
This list does not include all expendable mainte-
nance parts. Expendable emission related parts
requiring scheduled maintenance are warranted
until their first scheduled replacement point. See
Specific warranty exclusions below.
General warranty limitations
To retain the dependability of the exhaust emis-
sion control originally built into your Scania ma-
rine diesel engine, it is essential that the engine is
installed according to Scania installation instruc-
tions and emission certificates.
In addition, You are responsible for the perfor-
mance of all scheduled maintenance or repairs
on your new Scania marine diesel engine. Scania
may deny a warranty claim if your failure to per-
form maintenance resulted in the failure of the
warranted part.
Receipts covering the performance of regular
maintenance should be retained in the event
questions arise concerning maintenance. The re-
ceipts should be transferred to each subsequent
owner of the marine vessel with the emission
warranted engine.
The Warranty covers the cost of repair and re-
placement parts and services of warranted com-
ponents and systems performed by an authorized
Scania distributor or dealer using genuine Scania
parts. You may elect to have maintenance, re-
placement or repair of these components and
systems performed by any repair establishment
or individual without invalidating the Warranty.
The use of other than Scania replacement parts
also does not invalidate the warranty on other
components unless such parts cause damage to
warranted parts. However, the cost of such ser-
vices or parts will not be covered by the Warran-
ty.
If you install the engine in a way that makes the
engine's emission control information label hard
to read during normal engine maintenance, you
must place a duplicate label on the vessel, as de-
scribed in 40 CFR 1068.105.
IMPORTANT!
Use of replacement parts which are not of equiv-
alent quality may impair the effectiveness of
emission control systems. Accordingly, it is rec-
ommended that only Scania repair or replace-
ment parts be used for maintenance, repair or
replacement of emission control systems.
If other than Scania parts are used for mainte-
nance, repair or replacement, the owner should
obtain assurance that such parts are warranted by
their manufacturer to be equivalent to genuine
Scania parts.
