Safety precautions and instructions
Solé Diesel is concerned for your safety and your machine’s condition. Safety Precautions and
Instructions are one of the primary ways to call your attention to the potential hazards associated with
our engine operation. Follow the precautions listed throughout the manual before and during operation
and maintenance procedures for your safety, the safety of others and the performance of your engine.
Types of Safety Precautions:
Indicates the presence of a hazard that can cause severe personal injuries, death or
substantial property damages.
Indicates the presence of a hazard that will or can cause minor personal injury or property
damages.
Communicates installation, operation and maintenance information that is safety related but
not hazard related.
Servicing the fuel system and combustible materials. A flash fire can cause severe injury or
death
Do not smoke or permit flames or sparks near the fuel injection system, fuel line, fuel
filter, fuel pump, or other potential sources of spilled fuels or fuel vapors. Never add fuel
to the tank while the engine is running because spilled fuel may ignite on contact with
hot parts or from sparks.
Catch fuels in an approved container when removing the fuel line or fuel system. Keep
the fuel lines and connections tight and in good condition. Do not replace flexible fuel
lines with rigid lines and use flexible sections to avoid fuel line breakage caused by vibrations.
Keep the compartment and the engine clean and free of debris to minimize the risk of fire.
Servicing the air cleaner. A sudden backfire can cause severe injury or death.
Do not operate the engine with the air cleaner/silencer removed.
Combustible materials. A fire can cause severe injury or death.
Engine fuels, fuel vapors and combustible materials are flammable and explosive.
Handle these materials carefully to minimize the risk of fire or explosion. Equip the
compartment or nearby area with a fully charged fire extinguisher.
In case of fire do not open sound shield compartment and follow these instructions:
-Shut down engine(s)
-Continuously discharge entire contents of a halon or CO2 portable fire extinguisher
(or other provision) immediately.
Carbon monoxide (CO) can cause severe nausea, fainting or death.

Marine diesel engines. Operator’s manual
Engine exhaust gases contains carbon monoxide gas. Carbon monoxide is an
odourless, colourless, tasteless, no irritating gas that can cause death if inhaled for
even a short time.
Get fresh air and do not sit, lie down or fall asleep if anyone shows signs of carbon
monoxide poisoning:
-Light-headedness, dizziness
-Physical fatigue, weakness in joints and muscles. Sleepiness, mental fatigue,
inability to concentrate or speak clearly, blurred vision. Stomachache, vomiting,
nausea.
Keep the area around the battery well ventilated. While the engine is running or the battery
is charging, hydrogen gas is produced which can be easily ignited.
Never allow battery fluid (battery contains sulfuric acid) to come in contact with
clothing, skin or eyes. Always wear safety gloves and protective clothing when servicing
the battery. If battery fluid contacts the eyes and/or skin, immediately flush the
affected area with a large amount of clean water and obtain prompt medical treatment.
Moving parts. Keep hands, feet, hair, clothing and test leads away from
the belts and pulleys when the engine is running. Replace guards, screens
and covers before operating the engine.
Before working on the engine or connected equipment, disable the engine as follows:
Set the engine controller to OFF position.
(1) Disconnect the power input from battery.
(2) Disconnect the battery cables. Remove the negative (-) lead first when
disconnecting the battery. Reconnect the negative (-) lead last when reconnecting the
battery.
Follow these precautions to prevent the starting of the engine by engine controller, remote
start/stop switch, or engine start command from a remote computer.
Never remove the cooler cap if the engine is hot. Steam and hot engine coolant will
spurt out and seriously burn you. Allow the engine to cool down before you attempt to
remove the cooler cap.
Read the engine operator's manual and understand it before operation and maintenance of
the engine, to ensure that it continues operating practices and maintenance procedures.
Hearing protection. Use to avoid hearing loss when handling the motor.
1. The installer/operator of the engine has to wear suitable CLOTHING for the workplace and the
situation; in particular, avoid loose clothes, chains, bracelets, rings and all accessories that
could become entangled with moving parts.
2. The installer/operator of the engine has to wear personal protective equipment such as
gloves, work shoes, eye and hearing protection as required by the task.
3. The area in which the operator is working has to be kept tidy and free of oil and other liquid
spillages and solid waste (metal chips, etc.).

engine and replace the seawater filter cover. Before starting the engine again, open the
seawater cock.
Repeat this operation whenever the engine is used at temperatures below 0ºC.
3. Use oil with suitable quality and viscosity. SAE 15W40 is recommended. Under extreme
conditions contact with technical support.
4. Cover battery with an adequate material to protect it against the cold. Check that the
battery is fully charged.
It is also advisable to use a dielectric spray on the electrical connections.
5. When starting the engine, make sure that the glow plugs become hot enough.
6. If necessary, replace the diesel oil by a specified diesel oil type for low temperatures.
The accumulation of impurities in the fuel tank could cause faulty firing.
All engines not in use are subject to rusting and corrosion of machined surfaces that are not
protected with a paint coating. The degree of corrosion depends on meteorological changes and
climatic conditions. The following recommendations are therefore of a general nature but they will help
prevent or reduce the risk of damage due to rusting.

4.5. Winterization and preservation
If the boat is not going to be used for a long period of time or during the winter, certain tasks
must be carried out to keep it in perfect operating condition. Follow the steps indicated below carefully:
1. Clean the outer surface of the engine.
2. Bleed the seawater circuit by filling it with fresh water. Fill the seawater circuit again with a
mixture of fresh water and anti-freezing agent.
3. Remove the impeller from the seawater pump, clean it with fresh water and store it in place
protected from moisture and sunlight.
4. Renew and refill the heat exchanger to the maximum level with a mixture of fresh water and
anti-freezing agent.
5. Renew the oil in the engine.
6. Cover the air intake.
7. If the fuel tank is small, empty it completely and clean it; fill it up again with a mixture of
diesel and anti-corrosion additive. Solé S.A. recommends DIECYL PLUS. Add one measure of
this additive for every 25 liters of diesel. On the other hand, if the fuel tank is large, add 1
liter of this additive for every 500 liters of diesel.
8. Clean and dry the area where the engine is installed.
9. Loosen the belts.
10. Apply dielectric spray on the electrical connection, disassemble the battery and charge it
several times during the time it is not being used.
11. Apply moisture repellent spray on the motor.
4.6. Maintenance during the storage
During the long engine storage, it has to be stored inside a ventilated area and free of
humidity.
When the engine stay stopped for 3 months or more, inside parts can be oxidize and lost the
oil film. As a result, the engine could to size up after the storage. To avoid this, the engine must work
periodically during the storage.
Realize the following steps at least once per month:
1. In case that has a battery next to the engine, check the electrolyte level and fill it.
2. Start the engine during approximately 10 seconds.
3. Stop the engine during 1 minute. Repeat this action two or three times.
4. Be sure that oil pressure of the engine increase.
5. Get the engine work during 5 or 10 minutes without load, as maintenance operation.
4.7. Restoration of operational conditions
When starting up the engine again after winter lay-up, certain operations must be
performed. Follow these steps:
1. Fill the fuel tank with clean diesel. The mixture of diesel oil and anti-corrosion additive in
tank for winter lay-up can be used to operate the engine.
2. Check the fuel filter. If the filter is clogged, replace the filter.
3. Renew the oil in the engine.
4. Check the condition of coolant circuit’s rubber hoses.
5. Reconnect the battery and apply a layer of neutral Vaseline to the battery terminals.
6. Remove the nozzle supports and clean them. If possible, verify the setting of the nozzles
at a workshop. Then install the clean nozzles.
7. Connect the cooling and exhaust system. Open the seawater cock.
8. Verify whether there are any leaks in the fuel, coolant and oil systems.

5.1. Safety and prevention
Information of special tools required and basic safety precautions.
Disassembly:
✓Use the correct tools and instruments. Serious injury or damage to the engine can result
from using the wrong tools and instruments.
✓Use an overhaul stand or work bench if necessary. Also, use assembly bins to keep the
engine parts in order of removal.
✓Lay down disassembled or cleaned parts in the order in which they were removed. This
will save you time at reassembly.
✓Pay attention to the marks on assemblies, components and parts for positions or
directions. Put on your own marks, if necessary, to aid reassembly.
✓Carefully check each part for faults during removal or cleaning. Signs of abnormal wear
will tell if parts or assemblies are functioning improperly.
✓When lifting or carrying heavy parts, get someone to help you if the part is too awkward
for one person to handle. Use jacks and chain blocks when necessary.
Reassembly:
✓Wash all engine parts, except oil seals, O-rings, rubber seals, etc. in cleaning solvent and
dry them.
✓Use only the correct tools and instruments.
✓Use only good quality lubricating oils and greases. Be sure to apply a coat of oil, grease,
or sealant to parts as specified.
✓Use a torque wrench to tighten parts when specified tightening torques is required.
✓Replace all gaskets and packing. Apply appropriate amount of adhesive or liquid gasket
when required.
✓Increase the frequency of maintenance in harsh duty conditions (frequent stops and
starts, dusty surrounding, prolonged winter season, no-load running).
✓Risk of burns during maintenance operations carried out when the engine is hot. Wear
suitable safety clothing.
✓It is strictly forbidden to clean the engine with compressed air.
✓It is strictly forbidden to perform maintenance/cleaning operations in the presence of
moving parts.
✓Use gloves, overalls, etc. to protect the body from burns.
5.2. Periodic maintenance schedule
The maintenance and fault diagnostic procedures involve risks that may cause severe injury
or even death. These procedures should therefore be carried out solely by qualified electrical and
mechanical specialists. Before any maintenance and cleaning work, make sure that there are no
moving parts that the generator housing has cooled to ambient temperature, that the electricity
generating set cannot be accidentally started up and that all procedures are strictly observed.
