Safety regulations during engine operation
Filling fuel
There is a risk of fire and explosion when filling fuel.
Smoking is prohibited and the engine must be turned
off.Neveroverfill the tank. Close the filler cap secure-
ly.Use only fuel recommended in the operators ma-
nual. The incorrect grade of fuel can disturb operation
or cause breakdown. This can also lead to the control
rod jamming on diesel engines, which will cause the
engine to overspeed and risk damaging machinery
and causing personal injury.
Combustible enviroment
Due to the risk of fire and/or explosion, do not start
or continue to run the engine if there is a suspected
leak or discharge of combustible media, e.g. fuel oil
or LPG, in the engine surroundings.
The new engine
Read instruction manuals and other information ac-
companying the new vessel thoroughly.Accustom
yourself with handling the engine, controls and other
equipment in a safe and correct manner.
Remember that when operating a vessel, you have
a legal responsibility to be aware of and follow regu-
lations concerning traffic and safety at sea. Inform
yourself of the regulations applicable to your vessel
and the waters your in by getting in touch with the re-
levant authorities or marine safety organization.
Accidents and other incidents
Sea rescue statistics show that deficient mainte-
nance of vessels and engines together with defective
safety equipment often causes accidents and other
incidents at sea.
Make sure your vessel and engine are maintained in
accordance with directions in the instruction manuals
and that the safety equipment on board is in good
working order.
Daily inspection
Make a habit of visually inspecting the engine and
engine room before starting and after stopping the
engine.This will help you to quickly detect any fuel,
coolant or oil leaks and any other abnormalities that
have occurred or are about to occur.
Maneuvering
Avoid violent and rapid rudder movement and gear
shifting. There is a risk of the passengers falling down
or falling overboard. A rotating propeller can cause
serious injury. Make sure there is nobody in the water
before engaging forward/reverse.Neverrun close to
bathers or in places where you have reason to be-
lieve there are people in the water.

Safety information

IMPORTANT! Safety equipment: life jackets foreveryone on board, communication equipment,
distress rockets, approved fire extinguisher, bandages, life buoy, anchor, paddle, torch, etc.
lSpare parts and tools: Impeller, fuel filter, fuses, adhesive tape, hose clips, engine oil, propeller
and tools for tasks it may be necessary to perform.
lPlan your desired route from the charts.Calculate distance and fuel consumption. Listen to
weather reports.
lInform relations of your planned route for long trips.Remember to inform of changed plans or
delays.
lInform the people on board of where the safety equipment is located and how it works. Make
sure there is more than one person on board that knows how to start and maneuver the boat
safely.
This list should be supplemented with necessary safety equipment depending on the type of boat,
where and how it is being used, etc. We recommend you get in touch with a regional boat or marine
safety organization to obtain more detailed marine safety information.
Carbon monoxide poisoning
When a vessel is moving forward, it will cause a certain vacuum to form behind the vessel. In unfortunate
circumstances, the suction from this vacuum can be so great that the exhaust gases from the vessel are drawn
into the bridge or cabin and cause carbon monoxide poisoning. This problem is most prevalent on high, wide
vessels with abrupt stern. Other factors that can increase the effect of the suction are wind conditions, load dist-
ribution, swells, trim, open hatches and portholes, etc. Most modern vessels, however, are designed in such a
way that this problem is very rare.If suction should arise anyway, do not open hatches or portholes at the fore
of the vessel. Surprisingly, this will otherwise increase the suction. Tr y changing speed, trim, or load distribution
instead. Get in touch with your Volvo Penta dealer for help in obtaining the best solution foryour vessel.

Safety information

Safety directions for maintenance and service
Before starting
Refit all guards and covers that have been removed
before starting the engine.Make sure there are no
tools or other objects left on the engine.A turbochar-
ged engine must never be started without the air filter
fitted. The rotating compressor wheel in the turbo-
charger can cause severe personal injury.
There is also a risk of foreign objects being drawn in
and causing mechanical damage.
Fire and explosion
Fuel and lubricants
All fuels, most lubricants, and many chemicals are
flammable substances.Always read and follow the
directions on the packaging. Work performed on the
fuel system must be done on a cold engine.Fuel
leaks and spills on hot surfaces or electrical compo-
nents can cause fires.
Keep oil- and fuel drenched rags and other hazar-
dous materials where they are safe in case of fire.
Oil drenched rags can selfignite in certain conditions.
Never smoke when refueling, topping up with oil or
when in the vicinity of the fuel station or the engine
room.
Non-original parts
Components in fuel, lubrication, ignition and electrical
systems on Volvo Penta engines are designed and
manufactured to minimize the risk of explosion and
fire in compliance with existing legislation.
The use of non-original parts can result in explosion
or fire.
Batteries
Batteries contain and generate oxyhydrogen gas, es-
pecially when charging. Oxyhydrogen is easily ignited
and extremely explosive. Smoking, open flames and
sparks must never occur in, or close to, the batteries
or battery compartment. A faulty battery connection
or jumper cable can generate sparks that can cause
the battery to explode.
Start spray
Never use start spray or similar start help.Explosions
can occur in the intake manifold. Risk for personal
injury.
Preparations
Knowledge
The operator’s manual contains directions for perfor-
ming normal maintenance and service in a safe and
correct manner.Read the directions carefully before
starting work.More detailed service literature is av-
ailable from your Volvo Penta dealer.Never perform
a task unless you are absolutely sure how it is to be
carried out; call your Volvo Penta dealer for assis-
tance instead.
Stop the engine
Stop the engine before opening or dismantling the
engine hatch/hood. Maintenance and service must
be carried out with the engine stationary unless sta-
ted otherwise in the instructions.Prevent inadvertent
start of the engine by removing the starter key and
turning off the power with the main switch, locking it
in the off position. Place warning signs stating that
service is in progress in every position from which the
engine can be started. Working on or approaching
arunning engine is a safety hazard. Loose clothing,
hair, fingers or a dropped tool can be caught in rota-
ting parts and cause serious bodily injury. Volvo Pen-
ta recommend leaving all work requiring the engine
to be running to an authorized Volvo Penta dealer.
Lifting the engine
Always use the lifting eyes mounted on the engine
when lifting the engine.Always make sure lifting
equipment is in good condition and constructed for
the lift (engine weight together with possible reverse
gear and extra equipment). Use an adjustable lifting
boom to ensure safe handling when lifting the engine.
All chains and wires must run parallel with each other
and as much at right angle as possible to the top of
the engine.Note that any extra equipment mounted
on the engine can change the center of gravity.Spe-
cial lifting devices may be required to obtain the right
balance and safe handling. Never perform service on
an engine suspended only from a lifting device.
IMPORTANT! Engine must only be lifted horizon-
tally.
IMPORTANT! Engine lifting eyes are designed
only for lifting an engine.Do not use the engine
lifting eyes when lifting an engine with a gearbox
mounted.

Safety information

Hot surfaces and fluids
At operating temperature, the engine and its com-
ponents are hot. A hot engine always involves risk
forburn injuries.Take care with hot surfaces.E.g.:
exhaust manifold, turbocharger, oil pan, charge air
pipe, starting heater, hot coolant and warm lubricant
in pipes and hoses.
WARNING! Do not open the crankcase co-
vers while the engine is still hot.
Carbon monoxide poisoning
Start the engine in well-ventilated spaces only.When
running in confined spaces, the exhaust gases and
crankcase gases must be evacuated.
Chemicals
Most chemicals such as glycol, anti-corrosion agent,
preservatives, degreasing agent, etc., are hazardous
to health. Always read and follow the directions on
the packaging.
Certain chemicals such as preservatives are flam-
mable and harmful to inhale.Provide good ventilation
and use breathing protection when spraying. Always
read and follow the directions on the packaging. Sto-
re chemicals and other hazardous materials out of
reach of children. Leave left over or used chemicals
to a destruction plant.
Cooling system
There is a risk of water entering when working on
the seawater system. Therefore, stop the engine and
close the seawater cock before starting work.
Avoid opening the coolant filler cap when the engine
is warm.Steam or hot coolant may spurt out and
cause burn injuries.
If the filler cap, coolant pipe, cock, etc., must ne-
vertheless be opened or dismantled while the engine
is warm, the filler cap must be opened carefully to
release the pressure before removing it completely
and starting work.Note that the coolant can still be
hot and cause burn injuries.
Lubricating system
Hot oil can cause burn injuries.Avoid skin contact
with warm oil. Make sure the lubricating system is
depressurized before starting work.Never start or run
the engine with the oil filler cap removed or there will
bearisk of the oil being thrown out.
Fuel system
Always protect your hands when carrying out leak
detection.
Escaping fluids under pressure can pierce bodily tis-
sue and cause serious injury. Risk of blood poisoning.
Always cover any electric component if it is located
under the fuel filter.Otherwise it might be damaged
by fuel spills.

Safety information

Electrical system
Tu rn off the power before commencing work on the
electrical system, the engine must be stopped and
the powered turned off with the main switch/switches.
Shore power to the engine heater, battery charger
or other extra equipment fitted to the engine must be
disconnected.
Batteries
Batteries contain a highly corrosive electrolyte.Pro-
tect your eyes, skin and clothing when charging and
handing batteries.Always use protective goggles and
gloves.
In case of splashes on the skin, wash with soap and
plenty of water.In case of splashes in the eyes, rinse
immediately with plenty of water and call a doctor.
Avoid burns and crushing or cutting!
At operating temperature, the engine coolant is hot
and under pressure.Steam can cause personal
injury. Check the coolant level only after the engine
has been stopped and the coolant filler cap has coo-
led enough to touch with your hand. Never adjust the
V-belts while the engine is running.
Service batteries carefully!
If you spill electrolyte on yourself, flush skin imme-
diately with lots of water.Apply baking soda to help
neutralize the acid. If electrolyte gets in your eyes,
rinse immediately with large amounts of water then
contact a doctor at once.
Handle antifreeze carefully!
Antifreeze contains alkali. Avoid contact with skin
and eyes to prevent personal injury. Dispose of drai-
ned antifreeze coolant according to local regulations.
For disposal, consult your dealer.
Dress properly for the job!
Wear protective devices - hard hat, face shield, safety
shoes, goggles, heavy gloves, ear protectors, etc. -
foryour own safety.
Recommended fuel, lubrication oil and coolant!
Use of any other fuel oil, lurication oil or coolant than
the recommended can cause engine damage and
reduce engine service life.
Perform all recommended inspections!

Care of the environment
We would all like to live in a clean and healthy en-
vironment. An environment where we can breathe
clean air, see healthy trees, have clean water in our
lakes and oceans, and are able to enjoy the sunshine
without being worried about our health. Unfortunately,
this cannot be taken forgranted nowadays but is so-
mething we must work together to achieve.
As a manufacturer of marine engines, Volvo Penta
has a special responsibility, why care of the environ-
ment is a core value in our product development. To -
day, Volvo Penta has a broad range of engines where
progress has been made in reducing exhaust emis-
sions, fuel consumption, engine noise, etc. We hope
you will take care in preserving these qualities.
Alwaysfollow any advice given in the operator’s
manual concerning fuel grades, operation and main-
tenance and you will avoid causing unnecessary in-
terference to the environment. Get in touch with your
Volvo Penta dealer if you notice any changes such as
increased fuel consumption exhaust smoke.
Adapt speed and distance to avoid wash and noise
disturbing or injuring animal life, moored boats, jetti-
es, etc. Leave islands and harbours in the same con-
dition as youwant to find them. Remember to always
leave hazardous waste such as waste oil, coolant,
paint and wash residue, flat batteries, etc., for dispo-
sal at a destruction plant. Our joint efforts will make a
valuable contribution to our environment.
Fuel and oil
Use only fuel and lubrication oil grades recommen-
ded in the technical data section of this Operator’s
Manual. Other grades can cause operational pro-
blems, increase fuel consumption and have long-
range effects on engine service life.
