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.

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.

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
electrical system.
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.

Cleaning the centrifugal oil
cleaner
WARNING!
The oil may be hot. Carefully remove the cover
from the centrifugal oil cleaner.
Note:
Always use genuine Scania parts during maintenance of the centrifugal oil cleaner. This will ensure that the centrifugal oil cleaner continues to
function.
Tools
When the centrifugal oil cleaner is cleaned, there
should be some dirt deposits in the rotor cover.
This indicates that the rotor is working. If the rotor cover is clean, in other words the rotor is not
working, the cause must be established immediately.
If the dirt deposit exceeds 28 mm at the recommended maintenance intervals, the rotor cover
should be cleaned more often.
1. Clean the cover. Unscrew the nut securing
the outer cover.
2. Let the oil run out from the rotor.
3. Lift out the rotor. Wipe off the outside. Undo
the rotor nut and unscrew it about 1.5 turns to
protect the bearing.

If the rotor nut is difficult to get loose, turn
the rotor upside down and fasten the rotor nut
in a vice. Turn the rotor anti-clockwise
1.5 turns by hand or use an M20 nut, see illustration.
IMPORTANT!
The rotor must not be put in a vice. Never strike
the rotor cover. This may cause damage resulting
in imbalance.
5. Remove the rotor cover by holding the rotor
in both hands and tapping the rotor nut
against the table. Never strike the rotor directly as this may damage its bearings.
6. Remove the strainer from the rotor cover. If
the strainer is stuck, insert a screwdriver between the rotor cover and strainer and carefully prise them apart.

Fit a new O-ring in the cover. Refit the cover
and tighten the lock nut.
IMPORTANT!
To reduce the risk of oil leakage it is important to
tighten the cover to the correct tightening torque.
From engine serial number 6 841 928:
Tightening torque 20 Nm.
Older engine serial number:
Tightening torque 15 Nm.
Operational testing
Operational testing need only be carried out if it
is suspected that the centrifugal oil cleaner is
malfunctioning. For example, if the dirt deposit
is abnormally small given the distance driven.
The rotor rotates very fast and should continue to
turn when the engine has stopped.
1. Run the engine until it reaches normal oper-
ating temperature.
2. Turn off the engine and listen for the sound
from the rotor. Use your hand to feel if the
filter housing is vibrating.
3. If the filter housing is not vibrating, disman-
tle and check the centrifugal oil cleaner.

Renewing the oil filter
Tools
IMPORTANT!
Clean the centrifugal oil cleaner at the same time
as you change the oil filter. Otherwise, the oil filter will be blocked and resistance in the filter will
increase. If this happens, an overflow valve in
the filter retainer opens and lets the oil pass without being filtered.
1. Remove the old filter.
2. Oil the rubber gasket on the new filter.
3. Tighten the filter by hand. Never use tools
because the filter could sustain damage, obstructing circulation.
4. Start the engine and check for leaks.
Renewing the double, commutative oil filter
During operation, the rotary control (1) should
point 90° towards the filter being used.
1. Turn the rotary control 90° to the right so that
it points towards filter B. The oil then flows
through the filter.
2. Clean filter A with a cloth.
3. Unscrew filter A.
4. Apply oil to the gasket on the new filter.
5. Fill the filter with engine oil.
6. Screw filter A into place by hand until it
makes contact.
7. Turn screw a further half turn by hand.
8. Turn the rotary control 90° to the left so that
the rotary control points towards filter A. Fil-

Coolant
WARNING!
Ethylene glycol can be fatal if ingested and can
cause skin irritation and eye damage.
Note:
The coolant should be changed when the cooling
system is cleaned: every 6,000 hours or at least
every 5 years. See Changing the coolant and
cleaning the cooling system.
The coolant has several characteristics which are
important for the operation of the cooling system:
• Corrosion protection
• Antifreeze
• Increases the boiling point
Scania recommends that the coolant used is a
mixture of water with antifreeze and corrosion
inhibitor (ethylene glycol). The coolant should
always contain 35-55% by volume of antifreeze
and corrosion inhibitor so that the coolant has the
correct properties for the cooling system to work.
Coolant resistance to cold
The following example shows coolant properties
with 30 percent by volume of antifreeze and corrosion inhibitor:
• Ice slush starts to form at -16°C (3°F).
• At -30°C (-22°F), there is a risk of cooling
system malfunction.
• There is no risk of damage by freezing with a
minimum antifreeze and corrosion inhibitor
content of 35 percent by volume.
The chart depicts coolant properties at different
percents of antifreeze and corrosion inhibitor
concentration by volume.

Antifreeze and corrosion protection
products
Only Scania coolant or other products that Scania has tested to provide proper antifreeze and corrosion protection, may be used in Scania
engines. Products that do not satisfy the requirements for use in a Scania engine can result in
faults in and damage to the cooling system. This
can lead to the invalidation of Scania's warranty
for faults and damage caused by the use of inappropriate coolant.
The antifreeze and corrosion protection products
used in Scania engines should be of the ethylene
glycol type.

Checking coolant level
WARNING!
Do not open the coolant filler cap in the expansion tank if the engine is hot. Hot coolant and
steam may spray out and cause burns.
If the cap has to be opened do it slowly and carefully to release the pressure before removing the
cap. Wear gloves as the coolant is still very hot.
IMPORTANT!
It is not permissible to top up large amounts of
coolant via the expansion tank. Filling via the expansion tank leads to air locks in the cooling system which can lead to e.g. damage to the coolant
pump shaft seal. If a large amount of coolant
must be added, follow the instructions in the section Filling coolant
.
Never fill a large amount of cold coolant in a hot
engine. There is great risk of cracks forming in
the cylinder block and cylinder heads.
Only pour pre-mixed coolant into the cooling
system.
The following instructions apply to Scania expansion tanks. For other types of expansion
tanks, follow the manufacturer's instructions.
1. Check the coolant level through the sight
glass on the expansion tank.
2. Top up with coolant as necessary.

Checking coolant antifreeze
and corrosion protection
Note:
Use only pure fresh water that is free from particles, sludge and other impurities.
Tools
1. Pour a small amount of coolant into a con-
tainer and check that the coolant is pure and
clear.
2. Change the coolant if it is contaminated or
cloudy.
3. Measure the antifreeze content with a refrac-
tometer.
The following rules apply to ethylene glycolbased coolant:
• The antifreeze and corrosion inhibitor content
must be minimum 35 percent by volume for
corrosion protection to be sufficient.
• An antifreeze and corrosion inhibitor content
greater than 55 percent by volume impairs the
ability to protect against frost.

Filling coolant
This procedure applies when the cooling system
has been drained and needs to be filled with a
large amount of coolant.
IMPORTANT!
It is not permissible to fill large amounts of coolant via the expansion tank. Filling via the expansion tank leads to air locks in the cooling system
which can lead to damage to the coolant pump
shaft seal for example.
Never fill a large amount of cold coolant in a hot
engine. There is great risk of cracks forming in
the cylinder block and cylinder heads.
Fill the cooling system only with ready-mixed
coolant.
Do not start the engine until the correct coolant
level has been obtained. If the engine is started
with a coolant level that is too low, the coolant
pump shaft seal may be damaged, which can result in leaks.
Special tools
1. Connect the coolant pump to the lowest drain
valve in the cooling system. The location of
the lowest drain valve for the engine may differ depending on engine application.
2. Connect the pump's 2 cable terminals to the
battery's negative and positive terminal.
Make sure that the filling starts. If the filling
does not start: Change the position of the cable terminals.

Fuel system
IMPORTANT!
The whole fuel system is very sensitive to dirt
and even very small particles. Foreign particles
in the system can cause serious malfunctions. It
is therefore very important that everything is as
clean as possible when work is carried out on the
fuel system. Before starting work on the fuel system, the engine must be washed. If possible, a
hot water wash should be used.
It is strictly forbidden to carry out any machining
work or work with compressed air near an open
fuel system.
Be extra careful and always use clean, lint-free
and dust-free clothes and gloves when working
on the fuel system. Scania recommends using
Tegera 848 gloves.
Clean tools before they are used and do not use
any worn or chrome-plated tools. Material and
flakes of chrome may come off.
Clean connections and the surrounding area before removal. When cleaning, cloths or paper
which shed fibres must not be used. Use clean
and lint free cloths, part number 588 879.
Plug or cover the connections during removal.
Also clean the connections before the components are fitted. Place removed components on a
thoroughly cleaned, dust-free surface. Scania
recommends using a stainless steel bench top,
part number 2 403 296. Cover the components
with a lint-free cloth.
Checking fuel level
Check the fuel level and top up with fuel as necessary.
Note:
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 Preparations for storage.

Checking and adjusting the valve
clearance
Note:
Checking and adjusting valve clearances should
also be carried out one more time after the first
500 hours of operation. Then the normal interval
will follow (every 2,000 hours).
Valve transition occurs when the cylinder
switches from exhaust stroke to intake stroke.
The exhaust valve is closing while the intake
valve is opening.
Carry out the adjustment on a cold engine.
Max. clearance between two valves under the
same valve bridge is 0.2 mm.
1. Read the mark on the flywheel in one of the
following ways:
– Rotate the flywheel in the normal direc-
tion of rotation using turning tool 99 309.
Read the mark on the flywheel visible in
the lower window of the flywheel housing.
– Engines fitted with flywheels marked
TDC UP: Fit turning tool 99 109 in flywheel housing holes of the upper window.
Press the pinion into the external ring gear
and turn the flywheel with a ratchet handle
and a 14 mm socket. Read the mark in the
upper window of the flywheel housing.
2. Adjust the valves according to Table for ad-
justing valves and unit injectors. It is a good
idea to mark the rocker arm with a pen after
adjustment to keep track of what has already
been adjusted.

Composition of the fuel
The composition of the fuel is extremely important for the operation and service life of the engine and injection system. The engine output and
exhaust gases are also dependent on the fuel
grade.
The requirements and testing standards for the
most important characteristics are described in
the Workshop Manual which can be ordered
from Scania dealers or directly from Scania.
The fuel must conform to EU standard EN590.
The table shows some of the key properties.
Property Requirement
Viscosity at 40°C
(104°F)
2.0-4.5 cSt
Density at 15°C (59°F) 0.82-0.86 cSt
Ignitability (CET rating) minimum 49
Flashpoint 56°C (132°F)
Sulphur content of fuel
IMPORTANT!
The machine operator is responsible for using
the correct type of fuel to ensure that local laws
are complied with.
• A sulphur content of 0-2,000 ppm in the fuel
(0.2%) gives an oil change interval of up to
500 hours.
• With a sulphur content of 2,000-4,000 ppm in
the fuel, the oil change interval is halved to
max. 250 hours.
• Maximum permitted sulphur content in the
fuel is 4,000 ppm.
Using DMX and DMA fuels in
marine engines
DMX and DMA fuels normally cause increased
wear on the injection system. As a result of the
high sulphur content in these fuels the engine oil
is also affected. The engine oil must have as high
a Total Base Number (TBN) as possible.
REQUIREMENT!
For engines running on DMX and DMA fuels the
engine oil must have a TBN of at least 12.
When the engine is taken into operation the engine oil must be analysed every 50 hours to determine the correct oil change interval. The oil
analysis must be carried out according to the Oil
analysis section in this Operator's manual.
Bear in mind that the emission limit for the current engine type may limit the maximum permitted sulphur content of the fuel.

Diesel
Temperature dependency of
the fuel
IMPORTANT!
Mixing kerosene or other paraffins with the fuel
is prohibited. The injectors may be damaged.
Mixing petrol with the fuel is prohibited. In the
long term petrol can cause wear in the injectors
and engine.
At temperatures lower than those specified for
the fuel, paraffin wax may precipitate from the
fuel and block filters and pipes. The engine can
then lose power or stop.
The fuel is adapted for use in the specific climate
of each country. If a vessel is to be operated in a
temperature zone with a temperature lower than
normal, first identify the temperature properties
of that particular fuel.
The properties of the fuel when cold can be improved by adopting one of the following measures before the temperature drops:
• Install an electric fuel heater if this particular
fuel is not suitable for the expected temperature and no fuel is available with the correct
temperature properties.
• Add 0.5-2% alcohol (isopropanol) to prevent
any water in the fuel from freezing and forming plugs of ice. Drain fuel tanks and drain or
renew fuel filters regularly.
Biodiesel (FAME)
Scania uses the term biodiesel according to the
EN 14214 standard to refer to renewable diesel
made from greases or oils and methanol. The
biodiesel should conform to the requirements of
European standard EN 14214. For biodiesel in
accordance with EN 14214 the generic term
FAME is frequently used.
All Scania engines are approved for diesel according to the EN 590 standard. EN 590 contains
up to 7% biodiesel in accordance with EN
14214. PDE engines may use up to 100%
EN 14214 biodiesel.
Maintenance intervals
With a greater mixture of biodiesel than EN 590,
the renewal intervals for the following are
halved:
• Fuel filter.
• Oil filter.
• Oil.
The oil viscosity must be xW-40.

Preparing the engine for storage
Preparing the engine for
storage
If the engine is not being used for an extended
period its cooling system, fuel system and combustion chamber and outside must be protected
against rust.
An alternative to preparing the engine for longterm storage is to start the engine and warm it up
every 6 months.
Handling the engine
The engine can normally stand idle for up to 6
months without preparation. For longer periods
of downtime, the following measures should be
taken. These measures provide protection for approximately 4 years.
Preparations for storage:
• Thoroughly clean the engine.
• Run the engine for a specific period using
special preservative fuel, oil and coolant.
• Otherwise prepare the engine for storage (filter renewal, lubrication, etc.).
Preservative coolant
If the engine is to be stored with a full cooling
system, use coolant containing 50 percent glycol
by volume. Glycol without nitrite-based inhibitor should be used. Example: BASF G48 or
BASF D542.
WARNING!
Ethylene glycol can be fatal if ingested. Avoid
contact with the skin.
Preservative fuel
Use diesel mixed with Lubrizol 560H or the
equivalent. Mix 1 cm
3
(ml)/0.06 in3 Lubrizol
560H in 10 dm
3
/2.3 US gallons of fuel.
WARNING!
Lubrizol 560H contains aromatic hydrocarbons
which are hazardous to health.
• Use spot extractors where there is a danger of
vapour build-up.
• Wear protective goggles and gloves when
handling the fuel.
• Do not use contaminated clothing.
• If it gets in your eyes: Flush with a gentle jet
of water for at least 15 minutes and contact a
doctor.
• If it gets on your skin: Wash with soap and
water.
• If you inhale it: Fresh air, rest and warmth.
• Store in well-sealed containers in a dry, cool,
place out of the reach of children.
Lubrizol is flammable and has a 2A fire rating.
The flashpoint is +27°C/81°F. In case of fire: Extinguish with carbon dioxide, powder or foam.
Preservative oil
Suitable preservative oils are supplied by most
oil companies. Example: Dinitrol 40 or equivalent.

Preparing the engine for storage
Preparations for storage
Environment
Use a container to avoid spills when draining the
oil and coolant. Dispose of used fluids through
an authorised waste disposal contractor.
Note:
Do not remove the injectors.
1. Drain and flush the cooling system.
2. Top up with preservative coolant.
3. Warm up the engine on normal fuel. Stop the
engine and drain the oil.
4. Renew the fuel filter.
5. Fill the engine with preservative oil up to the
minimum level on the oil dipstick.
6. Mix preservative fuel in a can. Detach the
fuel pipe at the feed pump suction line and
connect a hose from the can.
7. Detach the fuel pipe at the overflow valve
and connect a return hose to the can.
8. Start the engine and run it at about 1,000 rpm
for 20-25 minutes.
9. Stop the engine, remove the hoses and con-
nect the normal fuel pipes.
10. Remove the rocker covers and lubricate the
valve mechanisms with plenty of preservative oil. Refit the rocker covers.
11. Drain the preservative oil from the engine.
Fill with new engine oil immediately or
when the engine is to be reused.
12. Drain the coolant if the engine is not to be
stored with coolant in the system. Plug and
tape all coolant connections if the engine is
to be stored without coolant in the cooling
system.
13. Remove the sea water pump impeller if the
engine has a sea water pump.
14. Air cleaner: Clean or renew the filter ele-
ment.
15. Cover air intakes and exhaust pipes.
16. Alternator and starter motor: Spray with wa-
ter-repellent anti-corrosive oil, CRC 226,
LPS1 or the equivalent.
17. Spray the outside of bright engine parts, first
with penetrating preservative oil such as
Dinitrol 25B and then with Dinitrol 112 or
the equivalent.
Clearly mark the engine with the storage preparation date, and state that the engine must not be
started or cranked.
Batteries
WARNING!
Wear gloves and protective goggles when charging and handling batteries. The batteries contain
a highly corrosive acid.
Remove the batteries and trickle charge them at
the battery charging station. This does not apply
to batteries specified as maintenance-free by the
manufacturer.
The same applies to short-term storage, even if
the engine has not been prepared for storage as
above.
