Environment and safety
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 economy for Scania marine engines. To maintain
these throughout the entire service life of the engine, it is important for the user to follow the instructions on running, maintenance and fuel and
lubricating oil 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, fuel, 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 operating and maintaining Scania engines. The
equivalent text can also be found under the relevant maintenance item.

Environment and safety
Refuelling
WARNING!
During refuelling there is a risk of fire and explosion. The engine must be switched off and smoking 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.
If it is run in an enclosed space, there should be
an effective device to extract exhaust 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.

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 compartment. 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 follow the safety precautions on the relevant packaging.
Store chemicals and other materials which are
hazardous to health in approved and clearly
marked containers, where they are inaccessible
to unauthorised persons.

Starting and running
Starting and running
Checks before first start
Before the engine is started for the first time, carry out the maintenance items listed under First
start in the maintenance schedule. The following
must be checked:
• Oil level
• Coolant
•Fuel level
• Fluid level in batteries
• State of battery charge
• Condition of the drive belt
See also Maintenance intervals
.
Checks before running
Carry out daily maintenance as described in the
maintenance schedule prior to operation. See
Maintenance intervals
.
Starting the engine
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.
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 exhaust
gases and crankcase 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.
For environmental reasons the Scania engine has
been developed to be started with a low fuel feed.
Using unnecessarily large amounts of fuel when
starting the engine always results in emissions of
unburnt fuel.
1. Open the fuel cock if fitted.
2. Disengage the engine.
3. If the engine has a battery master switch:
Switch on the power by means of the battery
master switch.
4. Start the engine.
If the fuel tank has been run dry or if the engine
has not been used for a long time, bleed the fuel
system. See section Bleeding the fuel system us-
ing a hand pumpor Bleeding the fuel system using a suction tool.
OPM 250 en-GB 16

Scania CV AB 2016, Sweden
Starting and running
Starting at low temperatures
Take the local environmental requirements into
account. Use a fuel heater and engine heater to
avoid starting problems and white smoke.
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 a moderate load on a
cold engine limits white smoke, gives better
combustion and warms up the engine more
quickly than warming it up with no load.
Avoid running it longer than necessary at idling
speed.
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 nominal engine speed is indicated on the engine data
plate. Low idling can be set between 500 and
1,050 rpm.
Limp home mode
If there is a fault in the normal throttle opening or
if CAN communication is interrupted, the following emergency operation option is provided:
A CAN fault or throttle opening fault in an allspeed engine (both signal and idling switch):
• The throttle opening value is 0% and the engine is running at normal idling speed.
• The throttle opening value is 0% and the engine is running at raised idling speed (750
rpm) if this function is activated.
Throttle opening fault, but the idling switch is
working:
• The throttle opening value can be increased
slowly between 0 and 50% by using the idling
switch.
CAN fault:
• The engine is switched off if the shutdown
function is activated.
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.
• ICFN and PRP engines may be used at an altitude of up to 2,000 metres.
• IFN, Patrol Craft Long and Patrol Craft Short
engines must not be used at an altitude of
more than 1,000 metres.
• Contact Scania if the operating conditions deviate from these.

Starting and running
Coolant temperature
IMPORTANT!
An excessively high coolant temperature can
damage the engine.
Normal coolant temperature during operation is
approximately 94°C/200°F.
The alarm levels are set in the engine control
unit. The default setting for the lowest and highest limit values for high coolant temperature are
95°C/203°F and 105°C/221°F respectively.
The high coolant temperature alarm has the following functions:
• Alarm only.
• Alarm and torque reduction at the lowest limit value.
• Alarm at the lowest limit value and engine
shutdown at the highest limit value.
• Alarm, torque reduction at the lowest limit
value and engine shutdown at the highest limit value.
• Alarm at the lowest limit value and engine
shutdown at the highest limit value with the
possibility of engine shutdown override control.
• Alarm, torque reduction at the lowest limit
value and engine shutdown at the highest limit value, with the possibility of engine shutdown override control.
If run for extended periods under an extremely
light load, the engine may have difficulty in
maintaining the coolant temperature. At an increased load the coolant temperature rises to the
normal value.
Oil pressure
Information about the normal oil pressure and
lowest permitted oil pressure is contained in the
Lubrication system
section in the Technical Data
chapter.
The engine management system has the following alarm levels:
• At an engine speed below 1,000 rpm and an
oil pressure below 0.7 bar/10.2 psi.
• At an engine speed above 1,000 rpm and an
oil pressure below 2.5 bar/36.3 psi for longer
than 3 seconds.
The incorrect oil pressure alarm has the following functions:
• Alarm only.
• Alarm and torque reduction by 30%.
• Alarm and engine shutdown.
• Alarm and engine shutdown override control.
Note:
High oil pressure (above 6 bar/87 psi) is normal
when starting a cold engine.
Charging indicator lamp
If the lamp comes on during operation:
• Check and adjust the drive belt according to
the section Checking the drive belt
.
If the charging indicator lamp is still on, this
could be due to an alternator fault or a fault in the

Belt transmission
When the belt transmission is new, it may make
a squeaking noise when running. The noise is
normal and disappears after 50-100 hours of operation. The noise does not affect the service life
of the belt transmission.

Starting and running
Engine shutdown
IMPORTANT!
There is risk of post boiling and of damage to the
turbocharger if the engine is switched off without cooling. The power must not be switched off
before the engine has stopped.
Note:
The battery voltage must remain on for a few
seconds after the 15 voltage is switched off so
that the control units can store the values and
switch to standby mode.
10 prohibited engine shutdowns will cause a
torque reduction (70% of fuel quantity). Reset
the engine by switching it off correctly once.
1. Run the engine without a load for a few min-
utes if it has been run continuously with a
heavy load.
2. Switch off the engine.
Checks after running
WARNING!
Block the starting device 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 turbochargers, 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 power supply has been cut.
2. Fill the fuel tank. Make sure that the filler
cap and the area round the filler opening are
clean to avoid contamination of the fuel.
3. If there is a risk of freezing, the cooling sys-
tem must contain enough glycol. See the section Coolant resistance to cold
.
4. If the temperature is below 0°C/32°F: Pre-
pare for the next start by connecting the engine heater (if fitted).

Oil grade
Scania LDF stands for the Scania Long Drain
Field test standard. Scania LDF oils have been
carefully selected after extensive testing. The approval is only granted to the highest quality engine oils available on the market.
The engine oil must fulfil the following quality
requirements:
• ACEA E5/API CI-4.
• ACEA E7/API CI-4 +.
• For engines not run on low-sulphur fuel, the
TBN (Total Base Number) should be at least
12 (ASTM D2896).
• Oils with a low ash content (ACEA E9/API
CJ4) are not recommended.
Check with your oil supplier that the oil meets
these requirements.
If the engine is used in areas of the world where
lubricating oil with ACEA or API classification
is not available, the oil grade must be measured
in actual operation. In this case contact the nearest Scania workshop.
For operation at extremely low outdoor temperatures: Consult your nearest Scania representative
on how to avoid starting difficulties.

Oil analysis
To be able to extend the oil change intervals using an oil analysis, Scania LDF-2 and LDF-3 oils
must be used. Oil companies can offer analysis
of the engine oil.
The following conditions must remain fulfilled
when the oil is changed:
• Viscosity at 100°C (212°F): max ±20% of
original value of the fresh oil.
• TBN (in accordance with ASTM D4739): >
3.5.
• TBN (in accordance with ASTM D4739): >
TAN (in accordance with ASTM D664).
• Soot (in accordance with DIN 51452): < 3%.
Such analysis measures the oil's TBN (Total
Base Number), TAN (Total Acid Number), fuel
dilution, water content, viscosity and the quantity of particles and soot in the oil. The result of a
series of analyses is used as the basis for establishing a suitable oil change interval.
If the conditions are changed, a new oil analysis
programme must be carried out to establish new
oil change intervals.
Checking oil level
Checking the oil level with the engine
switched off
Note:
Leave the engine off for at least 1 minute before
you check the oil level.
1. Remove the oil dipstick (1) and check the oil
level. The correct level is between the minimum and maximum marks on the oil dipstick.
2. Top up with more oil via the oil filler (2)
when the oil level is at or below the minimum mark.
For information on the correct oil type, see the
section Oil grade
.

Changing the oil
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
lubrication system before starting work on it.
The oil filler cap must always be in place when
starting and running the engine to prevent oil being ejected.
Note:
Renew the oil filter and clean the centrifugal oil
cleaner when changing oil.
Change oil more often if the engine is subjected
to particularly demanding operation, such as a
dusty environment, or if deposits in the centrifugal oil cleaner are thicker than 28 mm (1.1 in).
Environment
Use a suitable container. Used oil must be disposed of as specified in national and international laws and regulations.
1. Unscrew the oil plug and drain the oil when
the engine is hot. In certain engines the oil is
pumped out by means of a bilge pump.
When draining with the valve, the oil should
be hot. Alternatively, use a pump. This so
that draining occurs more quickly.
2. Clean the magnet on the oil plug.
3. Refit the oil plug.
4. Top up with oil.
5. Check the level on the oil dipstick.
Maximum angles of inclination during operation
Maximum permissible angles during operation
vary, depending on the type of oil sump. See illustration.
