2.5 Stopping the machine
1. Before stopping the diesel engine, engine must be kept without loads for a
few minutes, it is ideal that the water temperature drops below 70ºC before
stopping.
2. After the diesel engine stops, you must turn the ignition switch to the center
position (in engines used in generators this is not required).
3. In winter, when the environmental temperature is below 5°C: After engine
stops, (check the water temperature is below 60°C), open the radiator water
valve, remove the cooling water to prevent freezing inside the machine.
There is no need to draw water if antifreeze fluid was added to the water or
permanent water heater is used.
2.6 Security requirements
1. When engine is operating, all rotating and exposed parts may be dangerous
for operators so you must place warning marks.
Metallic protective covers must have sufficient stiffness so they can be removed
only with the use of tools.
2. The workplace of the diesel engine must be well ventilated, you should avoid
the buildup of flammable, toxic or asphyxiating gases in the place, when
possible; ventilation equipment must be installed.
3. The operating place of the diesel engine must have a nonskid base. Railings
must be installed in the aisle, platforms, stairs or other areas where operators
are to prevent falls of people or objects.
4. When the engine is working, it is necessary that this equipped with a water
thermometer, an oil pressure gauge and a plan of usage instructions.
5. When the engine is running and there is a sound that is not normal,
lubrication has failed or the combustion temperature in the exhaust is above the
limit, we must take the necessary measures to stop the engine quickly.
6. The fuel tank inlet and air outlets should be away from electrical and
electronic equipment in order to not affect them. Make sure the fuel tank is
securely fastened and has no leaks.
7. When installing the radiator it must placed in a visible area with a warning
mark indicating that the radiator cap should not be opened until the temperature
is reduced in order to avoid burn injuries.
8. The air outlet of the diesel engine and muffler are the most high temperature
surfaces. The operator should not touch the surfaces when the diesel engine is
running. Ensure fuel or oil do not come into contact with the exhaust to prevent
a fire.
9. When a diesel engine is used in the following conditions:
