    b) Keep the engine clean, because excessive amount of oil pollution may trigger the body damage caused by overheating and fire.

     Pre-operation Instruction

    1. Please select the proper light diesel which matches the operating environment, such as 0 # light diesel of national standards. Use 0 # light diesel in summer, use 10# or -20 #

    light diesel in southern region in winter and -30# or 35# light diesel in northern region in winter. Select CD.CF class light diesel oil in line with CYJ103A-711105-401 stated by Great Wall Company. Choose trademark according to the use of your generators power

    units. Otherwise cause irreparable damage to your equipments. (More Details on Our Diesel Engine Operation and Maintenance Manuals).

    2. Fill adequate amount of proper lubricating oil, which matches the operation temperature, such as SAE15W-40 oil. (More Details on Our Diesel Engine Operation and Maintenance Manuals).

    3. Choose suitable cooling water, such as the use of soft water, rain. (More Details on Our Diesel Engine Operation and Maintenance Manuals).

    4. Remove air from fuel circuit, by using hand pressure pump to press the fuel, and discharging the air in the circuit between fuel tank and filter, until there’s no bubble in the

    outflow of the fuel pipe line.

    5.

     Generator set must be connected to ground protection, and whether its neutral line should connect to the ground should meet the standards of local electric power. 6. Check the battery, and its connection. Connect anode to the starter motor, and cathode to the ground.

    7. For the sake of playing a normal battery performance, you should check the battery capacity and charge it at least three hours. When the storage batteries for more than 8 months or when need to used at low temperatures, you should recharging before using. 8. Do not permit allow generators battery as other use, because the capacity of battery is

    only limited to the use of the generator itself.

    9. Ensure that the electric floating charger under normal works at any time when the control system is equipment with electric floating charger.

    10. Disconnect the battery terminals, check the battery capacity regularly.

     Start the Generator Set

    (Note: Read the Operation Instruction of AD5000 Controller before starting the generator) 1. Before starting, make sure that all the pre-operation check has been done.

    Note: The parameter of Module AD5XXX has been set before delivery from the factory, therefore, amendment is prohibited, and could only been allowed after fully understanding the AD5XXX series control panel operating manuals or contacting the suppliers or our Technology Dept.

    2. Check the AS5XXX series control panel and see whether it is in normal state or not.

     1) If it shows “Stop……” press the Start button and then release it to get into starting state, and then it can be restarted.

    (To the generator of Isuzu’s engine: Pressing the starting button for 3-5 seconds until the

    running of generator, restarting it in next time if fail in 5 seconds , So do not exceed 5 seconds at best. The intervals between two starting must not exceeding 120 seconds)

     2) If it shows "Emergency Shutdown ……" the unit can be restarted after reposition of the Emergency Stop Button.

     3) If it shows "Lack of Oil Pressure Shutdown……" or other phenomena, the unit must be

    restarted after problems solved.

    4) Make sure pressed the reset button when starting generator every time 3. If AD5XXX fails to start after three times, its control panel will show failed reasons. Please solve the problems before re-starting again, or discharge the air from fuel circuit again.

    4. If it still fails to restart after problem-solving, please contact the supplier or our Technology Dept.

    5. After starting the generator set successfully, check the oil pressure and other parameters and see whether they are in normal state or not.

    6. Make sure whether your generator sets is auto starting function, if not, the auto starting button is useless, please starting the generator by manual process

    . Operating the Generator Set

    1. After starting the new generator sets, it shouldn’t get into full-load operation immediately.

    Instead, heat it up by letting it run without load first until the cooling water temperature reaches 50?, and then it can be running in full load.

    2. While operating, pay attention to its oil pressure, oil temperature and cooling water temperature, so as to make sure it is in normal state.

    3. While operating, pay attention to oil circuit, waterways and connecting spots. If it leaks, the problem should be eliminated immediately to prevent from wasting and pollution of the environment.

    4. New or overhauled diesel generator set should be set in operation for 60 hours before full load operation.

    5. It is not allowed to operate generator set with problems unsolved, so as to avoid damage to parts, unit accident, and personal injury.

    6. Don’t run the generator while the differences among phases is over 25%, otherwise, some accident will happen.

    7. For keeping your generator at good working state and generating electricity normally, you have to run it at least once per month, and the continuous time must not less than 20 minutes.

    8. In order to ensure the accuracy of generating units to the normal operation of power generation, you should start generating units once a month at least, and run 20 minutes. 9. Must always pay attention to the parameters of the display screen whether its normal

    or not, and also we need to pay attention to the color of exhaust smoke and the sound of operating. Stop the generator set immediately and check it when find out abnormal. When

running normally, increase capacity orderly until reach the rated load.

     Stopping the Generator Set

    1. If the unit is automatic generator set, when it is in auto state, and when power supply gets back to normal, the unit will switch automatically and stop after 120 seconds.

    2. Before stopping the generator set, please unload it first, and press the stop button on the control panel, then the unit will be stopped after delay.

    3. Prohibit stopping the unit when its water temperature is too high, except in emergent cases.

    4. When the temperature is below 5?, after stopping the unit, if without using anti-freeze

    liquid, the cooling water should be discharged totally so as to prevent the unit body and pump from being frost damaged.

    5. After it runs, trouble-shoot problems occurred during each operation. 6. Press emergent stop button, if you encounter some emergencies while operating. 7. Had best adjust the load from small to large, and then turn the generator off.

     Safety Operation Rules

    1. Never allowed the person who doesn’t know how to operate and who doesn’t have basic electrical knowledge to operate the unit.

    2. Make sure that all the pre-operation works have been done before starting except for automatic diesel generator set,

    3. Precautions against fire. Keep fire far away from the running unit. When the diesel generator set runs near the inflammable goods, adding fire extinguisher set on the exhaust pipe.

    4. Prohibit to disassemble and to adjust generator set while operating.

    5. Stop the unit when there is abnormal noise, and restart it after the problem been obviated.

    6. Always e careful during repairing or disassembly to avoid being injured by the running parts or other accidents.

    7. Keep generator set under integrity circumstances, clean and wipe the generator set entirely both pre-teardown and pre-assembly in order to ensure the perfect quality of assembly. Complicated adjustment and maintenance should be carried out indoors to prevent environmental pollution of the generator inner units.

    8. Our company is not responsible for all the negative consequences caused by

    self-alteration of the structure of generator set.

    9. Must choose genuine spare parts as replacement parts.

     Diesel Generator Set Maintenance

    Do regular technical maintenance, and operate the generator set properly. Keep the generator set in good technical equipment and proper maintenance, so as to extend the service life.

    1. It is very important to us the right lubrication oil, which will make the engine work normally

    and extend the service time.

    The choice of lubrication oil depends on quality grade and Viscosity rank made by API

    and SAE respectively. Viscosity rank of lubrication oil adopts the international SAE

    standard. For example, lubrication oil of SAE15W/40 is multistage machine oils, whose working environment is under -10?~+45?. Using multistage machine oils will extend the

    oil change period. If environment temperature is lower than permitted temperature, it will

     - 7 -

influence the engine cold starting. Environment temperature higher than the permitted

    temperature for a long time will cause the initial engine damage.

    2Use of the coolant

    The non-air cooled generating set use water as the cooling medium; it should use the water which

    has been processed, and add some definite proportions antiseptic into it. Antifreeze should be used

    under low temperature(blow?)

    For preventing water incrustation forming in the cooling system, and influence the cooling effect

    of the engine. Usually we can use she water which has been boiled & deposited and filtrated.(PH

    class6-8)

    It also has she same function as she antiseptic. The antifreeze could be confected by she processed

    soft water and add 40%VOLVO ethanol antifreeze. The freezing point of this kind of proportional

    antifreeze is -25?, the freezing point will be -40? if still add additive and make

    the concentration high than 50?. Then the drop of the freezing point will indistinct and the cooling effect will also be influenced if remain to increase the proportion.

    In the areas where has no for preventing frostbite, VOLVO anticorrosion additive

    should be added into the coolant. The cubage proportion should be

    30(water):1(anticorrosion additive).It could reduce the aperture cauterization of

    the cylinder liner. But dont add any antiseptic into the coolant which has been filled with antifreeze, to avoid producing a lot of bubble and depress the effect

    of the coolant. Please pay more regards to safety because of this two kind of additive

    do harm to people.

    The major target which influences the quality of the diesel is the sulfur content.

    If the sulfur content is higher than 0.5%,it will have strong impact on the service

    life of the engine, and shorten replace cycle of the replacing the lube.

    Then Gen set should use the best quality solar oil which accord with the regulations

    of nation. The main way to choose the diesel oil is according the ambient temperature.

    The fuel will be congealed and the engine will be difficult to star and run if choose

    the wrong type in the clod district.

    Please see the following form for the coincidence relation of the type of solar oil

    and ambient temperature:

Ambient? >12 >412 >-54 >-14-5 >-29-14 >-44-29

    Fuel type 10 0 -10 -20 -35 -50

    The daily check-up & maintenance works of the Generator mainly carried out according

    to the manual of the manufacturer.

1. The oil change cycle should according to the condition of service and oil quality.

    The oil change cycle is according to 250400hours worked for the ordinary circs.

     - 8 -

2. It is necessary step to keep the super performance of the lube oil to replace

    the oil filter and filter element.

For avoiding the high precision & high pressure oil pump would be damaged, any diesel

    should be filtrated before enter into the oil transfer pump. The strainer of the

    fuel filter should be replaced or cleaned after working for 250400hours. Would

    be brought forward based on the oiliness.

1. The cleaning interval of intercooler and radiator should be confirmed accord to

    the working environment of Gen set. Commonly the internal system should be cleaned

    with neuter cleaning agent and pure water per 15002000hour. And should often to

    check and clean begrime on the heat sink.

    2. The coolant should be replaced entirely after the cooling system has been cleaned.

The maintenance of the inlet system mostly is to check, clean and replace element

    of air cleaner.

    1. The non-throwaway air filter could discharge the dust from the dust outlet, open

    the covering and take out he filter element with the pressed air(the supreme

    air pressure should no more than 500Kpa).And blow it from outside or clap it

    lightly. As the same time, check whether the filter element by photic method

    is out of repair or not, and please pay attention not to let the seal ring been

    damaged. And the filter element should be replaced at least once per year.

    2. The air resistance indicator of throwaway air filter should be checked after

    the engine has stopped. Please replace the air filter if there appears red mark.

    Press the barrage indicator for restoration. The air filter which has been

    replaced could be recycled again.
