Important information
Serious risk of injury
When working on the engine, for example when adjusting drive belts and the clutch, or when changing the
oil, it is important not to start the engine. The engine could be damaged, but more importantly there is a
serious risk of injury.
Therefore, block the starting device and switch off the manual fuel cock when working on the engine. This
is especially important if the engine has a remote starter or automatic starting.
WARNING!
This warning symbol and text can be found next to those maintenance items where it is particularly impor-
tant to bear in mind the risk of injury.

Environment and safety
Environmental responsibility
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 and operating econ-
omy for Scania engines. To maintain these
throughout the entire service life of the engine, it
is important for the user to follow the instruc-
tions on running, maintenance and fuel, lubricat-
ing oil and coolant as outlined in the Operator's
manual.
Other green initiatives taken include ensuring
that, following maintenance and repair, waste
that is harmful to the environment (for example
oil, coolant, filters and batteries) is disposed of
accordance with the applicable environmental
requirements.
Safety
The following pages contain a summary of the
safety precautions to be complied with when op-
erating and maintaining Scania engines. The
equivalent text can also be found under the rele-
vant maintenance item.
To prevent damage to the engine and personal in-
jury, and to ensure that it runs optimally, follow
the instructions in the warnings and advisories.
If the instructions are not followed, the warranty
can cease to apply.
Different types of advisory
Warning!
All advisories preceded by Warning! are very
important. They warn of serious faults and incor-
rect operation that could lead to personal injury.
Example:
WARNING!
Block the starting device and switch off the man-
ual fuel cock when working on the engine. If the

Environment and safety
Environment
This Operator’s manual contains specially high-
lighted text with instructions to help protect the
environment during maintenance. Example:
Environment
Use a suitable container. Used coolant must be
disposed of as specified in national and interna-
tional laws and regulations.
Warnings and advisories
Fuel
The engine is designed and optimised to be run
on either natural gas or pure biogas.
WARNING!
Natural gas and pure biogas mainly consist of
methane, and may have a methane content of up
to 97%. Methane is flammable and must be han-
dled with great care.
WARNING!
Methane is not toxic, but in a mixture of 50 per
cent or more with air, the oxygen content will be
so low that the risk of suffocation increases.
IMPORTANT!
Comply with applicable local laws and regula-
tions when handling natural gas and pure biogas.
Methane is a highly flammable gas which is
flammable when present in a 5-16% mixture in
the air.
Methane can even be ignited by static electricity
from a person.
Methane ignites when in contact with hot surfac-
es at approx. 580°C.
Methane burns with an almost invisible flame.
Therefore, take extra care.
Methane is lighter than air and therefore rises in
the event of leakage. Bear this in mind if leaks do
occur in enclosed spaces such as indoors or in a
tunnel. In those cases the gas can cause suffoca-
tion and an explosive atmosphere.
Smoking
WARNING!
Smoking is prohibited in the vicinity of gas en-
gines.
OPM 320 en-GB 8

Environment and safety
Safety precautions for running the
engine
Daily maintenance
Always carry out a visual inspection of the en-
gine and engine compartment before starting the
engine or when the engine has been switched off
after operation.
This inspection should be done to detect fuel, oil
or coolant leaks, or anything else that may re-
quire corrective action.
Fuel
WARNING!
Fuel of the wrong quality can cause malfunctions
or cause the engine to stop. This can cause dam-
age to the engine and, possibly, personal injury.
REQUIREMENT!
Use only fuel which fulfils the requirements in
the Quality requirements for fuel section.
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 effective devices to extract gas and
exhaust 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.
Running
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.

Environment and safety
Safety precautions for handling ma-
terials
Lubricating oil
WARNING!
All lubricants and many chemicals are flamma-
ble. Always follow the instructions on the rele-
vant packaging.
The work must be carried out on a cold engine.
Spillage on hot surfaces can cause fires.
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.

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.
Hot surfaces and fluids
WARNING!
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are engine
manifolds, turbochargers, oil sumps, as well as
hot coolant and oil in pipes and hoses.
Lubrication system
WARNING!
Hot oil can cause burns and skin irritation. Wear
protective gloves and goggles 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 running in order to avoid oil escap-
ing.
Environment
Used oil must be disposed of as specified in na-
tional and international laws and regulations.
OPM 320 en-GB 11

Environment and safety
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 protective gog-
gles 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.
Fuel system
WARNING!
Natural gas and pure biogas are extremely flam-
mable and can even be ignited by static electric-
ity from a person.
Natural gas and pure biogas are lighter than air
and therefore rise in the event of leakage. Be
aware of if there is a leak in a confined space. In
those cases the gas can cause suffocation and an
explosive atmosphere.
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.
IMPORTANT!
Work on the engine may only be carried out by
personnel who are aware of the risks and have
sufficient knowledge of natural gas and pure bi-
ogas.
Comply with applicable local laws and regula-
tions when handling natural gas and pure biogas.
The operator is responsible for using the correct
type of gas to ensure that local laws are complied
with.
Environment and safety
OPM 320 en-GB 12
© Scania CV AB 2019, Sweden
Before working on the engine, ensure that the
gas content of the air is below 10% of the lower
explosive limit (LEL). Also check the permitted
gas content with reference to local laws and reg-
ulations.
When working on the engine, use warning plates
indicating that work with flammable fuel is in
progress. Warning signs should be written in the
local language. Comply with local regulations on
the design of warning signs. An example of the
design of a warning sign is shown in the illustra-
tion.
Inform all personnel of the basic risks of natural
gas and pure biogas.
Check the grounding of the engine where open
handling of gas takes place, i.e. handling which
may give rise to an explosive atmosphere.
Never attempt to put out a burning gas flame. Try
to stop the flow of gas instead. Move material
that could be ignited by the flame.
Electrical system
WARNING!
Before working on the electrical system, ensure
that the gas content of the air is below 10% of the
lower explosive limit (LEL). Also check the per-
mitted gas content with reference to local laws
and regulations.
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.

Checks before first start
Before the engine is started for the first time, car-
ry out the maintenance items listed under First
start in the maintenance schedule. Check the fol-
lowing:
Oil level.
Coolant.
Fluid level in batteries.
State of battery charge.
Condition of the drive belt.
See also Maintenance interval
.
Checks before running
WARNING!
Block the starting device and switch off the man-
ual fuel cock when working on the engine. If the
engine starts unexpectedly, there is a serious risk
of injury.
Carry out daily maintenance as described in the
maintenance schedule prior to operation. See
Maintenance interval
.
Starting the engine
WARNING!
Only start the engine in a well-ventilated area.
When the engine is run in an enclosed space,
there must be effective devices to extract gas and
exhaust gases.
IMPORTANT!
The starter motor must only be cranked twice for
30 seconds at a time. After that, it must rest for at
least 5 minutes before the next attempt to start it.
1. Open the manual fuel cock.
2. Disconnect the engine from any load.
3. If the engine has a battery master switch:
Connect the power using the battery master
switch.
4. Start the engine.
5. The engine will rev up. Let the engine run
without load for 2 minutes.
Starting at low temperatures
Take the local environmental requirements into
account. Use the engine heater to avoid starting
difficulties. Scania recommends that an engine
heater should be used if the engine will be used
at temperatures below -10°C.
A low engine speed and moderate load on a cold
engine gives better combustion and faster heat-
ing than warming up with no load.
Avoid running it longer than necessary at idling
speed.
OPM 320 en-GB 18
© Scania CV AB 2019, Sweden
Starting and running
Running
Check instruments and warning lamps at regular
intervals.
Engine speed range
The engine operating speed range is between low
idling and the nominal engine speed. The nomi-
nal engine speed is 1,500 or 1,800 rpm. Low
idling is normally 1,000 rpm.
Driving at high altitude
When driving at high altitudes engine power is
reduced automatically due to the lower oxygen
content in the air. It is then not possible to run the
engine at maximum power.
Note:
Driving at a height higher than 2,000 metres
above sea level is only permitted if it has first
been approved by Scania.
Coolant temperature
IMPORTANT!
An excessive coolant temperature can cause en-
gine damage.
Normal coolant temperature during operation is
90-95°C (194-203°F).
Alarm levels are set in the engine control unit.
The default setting for the lowest and highest
limit values for high coolant temperature are
98°C (208°F) and 105°C (221°F) respectively.
The high coolant temperature alarm has the fol-
lowing functions:
Alarm at the lowest limit value.
Alarm at the lowest limit value and engine
shutdown at the highest limit value.
The engine is designed and optimised for contin-
uous operation at 100% load. To ensure opera-
tional reliability and to extend the maintenance
intervals, the following limitations for load and
operating time apply:
The accumulated total engine operating time at
less than 25% load should be < 5%.
The accumulated total engine operating time of
the engine at less than 40% load should be
<15%.
Oil pressure
For information on the normal oil pressure and
lowest permitted oil pressure, see the Technical
data section.
The engine management system activates an
alarm for high or low oil pressure at engine
speeds above 650 rpm. The values below are for
overpressure, not absolute pressure.
An alarm for high oil pressure is activated
when the pressure exceeds 7.9 bar (115 psi).
An alarm for low oil pressure is activated
when the oil pressure drops below 0.65 bar
(9 psi).
The incorrect oil pressure alarm has the follow-
ing functions:
Alarm only.
Alarm and engine shutdown.
Note:
High oil pressure (above 6 bar/87 psi) is normal
if the engine is cold when started.

If the charging indicator lamp is still on, this
could be due to an alternator fault or a fault in the
electrical system.
Belt transmission
When the belt transmission is new, it may make
a squeaking noise when running. This noise is
normal and disappears after 50-100 hours of op-
eration. The noise does not affect the service life
of the belt transmission.
Engine shutdown
IMPORTANT!
There is risk of post boiling and of damage to the
turbocharger if the engine is switched off with-
out cooling. The power must not be switched off
before the engine has stopped.
1. Run the engine without load for 3 minutes at
the nominal engine speed.
2. Switch off the engine via the coordinator and
allow the engine to run until the gas has run
out and the engine stops.
3. Close the manual fuel cock.
Checks after running
WARNING!
Block the starting device and switch off the man-
ual fuel cock when working on the engine. If the
engine starts unexpectedly, there is a serious risk
of injury.
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are turbo-
chargers, oil sumps, hot coolant and oil in pipes
and hoses.
IMPORTANT!
Check the coolant level following the first start.
Top up with coolant as necessary.
1. Check that the manual fuel cock is turned off.
2. Check that the power supply has been cut.
3. Check that the cooling system contains
enough glycol according to the Scania in-
structions. See the section Coolant
.
4. If the temperature is below 0°C (32°F): Pre-
pare for the next start by connecting the en-
gine heater (if fitted).
