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 injuries 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.

Combustible materials. A fire can cause severe injury or death.
Engine fuels, fuel vapours 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 CO2portable fire
extinguisher (or other provision) immediately.
Carbon monoxide (CO) can cause severe nausea, fainting or death.
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 (SVT) to OFF Mode.
(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.

engine. See warning label on the engine.
After starting up the engine, check the following points. If you find anything wrong,
immediately stop the engine, and then investigate the cause.

OPERATION
20
Operator’s Manual Marine Diesel Engines
Revision 0. 05/2016
1. Lubrication oil pressure should be from 0,19 to 0,39 MPa (2 to 4 kgf/cm2) (2 to 4 bar)
at nominal speed.
2. Coolant temperature should be 75 to 85ºC.
3. Oil temperature should be 60 to 95ºC.
4. Check for leakage of oil, coolant and fuel.
5. Knocking should die away as coolant temperature rises. No other defective noise
should be heard.
6. Check for exhaust colour and abnormal odours.
5.3. Stopping Engine
1. REMOVE ENGINE LOAD. Before turning off the engine, it
must be freed of all charges (disengaged gearbox to
neutral)
2. TURN THE KEY TO STOP POSITION. The key automatically
returns to the OFF position. All instruments are off.
3. CLOSE THE SEACOCK.
If the needle of tachometer is marking counter rpm when the engine is off, turn the key
back to ON and then OFF again.
5.4. Engine Operation at Low Temperatures
Whenever the atmospheric temperature drops below zero, the following series of
circumstances occur:
The cooling liquids may freeze.
The oil becomes thicker.
There is a drop in the voltage at the battery terminals.
The inlet air temperature is low and the engine has difficulty in starting.
The fuel loses fluidity.
To prevent the damage caused by low temperature operation, the engine should be
prepared:
1. Use special low temperature coolant or suitable anti-freezing agent concentration.
2. Close the seawater cock, when the engine is stopped. Open the seawater filter
cover and start the engine adding a mixture of freshwater and suitable anti-freezing
agent concentration (see package labels) until the seawater circuit is filled
completely. Stop the 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.
