2. OPERATING THE DIESEL GENERATOR
2-1 General main points of safety during operation of the generator set.
In order to operate the generator set safely,please follow all the instructions provided in this manual
carefully . Doing so otherwise may lead to accidents and or equipment damage.
2-1.1 Fire prevention
The proper fuel for the diesel generator set is light diese! fuel . Do not use gasoline, kerosene and or
other fuels other than light diesel fuel. Keep all flammable fuels away from the generator as the
generator may spark and ignite these gases. In order to prevent fires from occurring and to provide
enough ventilation for people and the machine ,keep the diesel generator at least 1.5meters or 5 feet
away from buildings and or other equipment.Always operate your diesel generator on a level site .lf
the generator is operated on an incline , the lubricating system within the engine will not perform
well and may lead to failure of the engine.
2-1.2 Prevention from inhaling exhaust gases
Never inhale exhaust gases emitted by the engine. The exhaust gases contain toxic carbon monoxi-
de.Never operate your generator in places with poor ventilation.ln order to operate this machinery
indoors , a suitable ventilation system for the building is required to draw the poisonous exhaust
gases out.
2-1.3 Prevention from accidental bums
Never touch the muffler and its cover when the diesel engine is running .Never touch the muffler and
cover after the diesel engine has been used, as the muffler remains hot for a good period of time.
2-1.4 Electris shock and short circuits
Never touch the generator if the generator is wet.Also never touch the generator if your hand is
wet.Never operate your generator if the weather conditions call for any type of precipitation such as
rain ,snow or fog .To prevent electrical shocks,the generator should be grounded. U se a lead to
connect the grounding end of the generator to the grounding surface of choice.
NOTE: When connection devices to the generator, make sure all other devices are rated lower than
the generators output. Any generator socket should not be overloaded over its regulated limit.
2-1.5 Other safety points
Before operating this generator, all operators should have a good knowledge of how to break the
circuit if any accidents occur .Also,all operators should be familiar with all the switches and func-
tions of the generator before using tkis machine .While operating the generator , wear safe shoes
and suitable clothes during operation.Always keep children and animals away from the generator.
2-1.6 Battery
The electrolytic liquid of the battery contains sulfuric acid .In order to protect your eyes,skin and
clothing ,wear protective gear when working with the battery.lf you come in contact with the elec-
trolytic liquid, wash it immediately with clean water.Also, if the electrolytic liquid comes in contact
with your eyes,see a doctor immediately.
2-2 Preparation before operation
2-2. l Fuel choices and fuel treatment
Fuel tank
Use only light diesel fue l. The fuel should be filtered clean. Never Jet dust and water mix with fuel in
the fuel tank. Otherwi se it will clog the fuel lines and oil nozzles. It may also damage your pressure
pump.
NOTE: lt is dangerous to overfill the fuel tank. Never exceed the red piston in the filter.
a. After purchasing fuel, put it into a drum and let it sit for 3-4 days.
b. 3-4 days later, insert half of the fuel sucker into the drum (water and impurities stay in the lower
portion of the drum).
Air filter element
Do not wash the air filter. The element is made of dry material, which does not permit washing.
When the output of the diesel engine is bad or the color of the exhaust gas is abnormal, replace the
air filter element. Never start the diesel engine without the air filter.
NOTE: Never smoke near the opening of the fuel tank. Do not let sparks get near the fuel or fuel tank
and do not overfill tank. After filling, tighten the fuel cap.
2-2.2 Fill engine oil
Fubrication Oil Filling Inlet
Put the generator set in level state. Fill the oil into the oilfilling inlet. At the time of checking the oil
level, it is necessary only to lightly insert the oil ruler. Please pay attention to that you should not
rotate the oil ruler.
Engine oil is the most important factor in deterrnining the life of your generator engine.If you
use poor engine oil or if you don't change the oil regularly,the piston and cylinder will wear
easily or seize up.Also,the life of the other parts in your engine such as bearings,and other
rotating parts will shorten considerably.
Although there is an alarm system to check for low oil pressure, it is always a good idea to check
the amount of oil inside the engine. lf the oil level is low, fill it before starting the engine. A good time
to drain the oil from the engine is when the diese! engine is still hot. If the engine is fully cooled, it is
more difficult to drain all the oil out or sorne impurities will remain in the engine.
WARNING: Don't fill engine oil when diesel is operating.
2-2.3 Check air filter
(1) Loosen the butterfly nut, take the cover of the air filter off and take the air filter element out.
Do not use detergent to wash the air filter element. When the performance of the engine decreases
or when the color of the exhaust gases is bad,exchange the filter element. Never start the engine
without the air filter as foreign objects may enter the intake and damage the engine.

2. OPERATING THE DIESEL GENERATOR
2-1 General main points of safety during operation of the generator set.
In order to operate the generator set safely,please follow all the instructions provided in this manual
carefully . Doing so otherwise may lead to accidents and or equipment damage.
2-1.1 Fire prevention
The proper fuel for the diesel generator set is light diese! fuel . Do not use gasoline, kerosene and or
other fuels other than light diesel fuel. Keep all flammable fuels away from the generator as the
generator may spark and ignite these gases. In order to prevent fires from occurring and to provide
enough ventilation for people and the machine ,keep the diesel generator at least 1.5meters or 5 feet
away from buildings and or other equipment.Always operate your diesel generator on a level site .lf
the generator is operated on an incline , the lubricating system within the engine will not perform
well and may lead to failure of the engine.
2-1.2 Prevention from inhaling exhaust gases
Never inhale exhaust gases emitted by the engine. The exhaust gases contain toxic carbon monoxi-
de.Never operate your generator in places with poor ventilation.ln order to operate this machinery
indoors , a suitable ventilation system for the building is required to draw the poisonous exhaust
gases out.
2-1.3 Prevention from accidental bums
Never touch the muffler and its cover when the diesel engine is running .Never touch the muffler and
cover after the diesel engine has been used, as the muffler remains hot for a good period of time.
2-1.4 Electris shock and short circuits
Never touch the generator if the generator is wet.Also never touch the generator if your hand is
wet.Never operate your generator if the weather conditions call for any type of precipitation such as
rain ,snow or fog .To prevent electrical shocks,the generator should be grounded. U se a lead to
connect the grounding end of the generator to the grounding surface of choice.
NOTE: When connection devices to the generator, make sure all other devices are rated lower than
the generators output. Any generator socket should not be overloaded over its regulated limit.
2-1.5 Other safety points
Before operating this generator, all operators should have a good knowledge of how to break the
circuit if any accidents occur .Also,all operators should be familiar with all the switches and func-
tions of the generator before using tkis machine .While operating the generator , wear safe shoes
and suitable clothes during operation.Always keep children and animals away from the generator.
2-1.6 Battery
The electrolytic liquid of the battery contains sulfuric acid .In order to protect your eyes,skin and
clothing ,wear protective gear when working with the battery.lf you come in contact with the elec-
trolytic liquid, wash it immediately with clean water.Also, if the electrolytic liquid comes in contact
with your eyes,see a doctor immediately.
2-2 Preparation before operation
2-2. l Fuel choices and fuel treatment
Fuel tank
Use only light diesel fue l. The fuel should be filtered clean. Never Jet dust and water mix with fuel in
the fuel tank. Otherwi se it will clog the fuel lines and oil nozzles. It may also damage your pressure
pump.
NOTE: lt is dangerous to overfill the fuel tank. Never exceed the red piston in the filter.
a. After purchasing fuel, put it into a drum and let it sit for 3-4 days.
b. 3-4 days later, insert half of the fuel sucker into the drum (water and impurities stay in the lower
portion of the drum).
Air filter element
Do not wash the air filter. The element is made of dry material, which does not permit washing.
When the output of the diesel engine is bad or the color of the exhaust gas is abnormal, replace the
air filter element. Never start the diesel engine without the air filter.
NOTE: Never smoke near the opening of the fuel tank. Do not let sparks get near the fuel or fuel tank
and do not overfill tank. After filling, tighten the fuel cap.
2-2.2 Fill engine oil
Fubrication Oil Filling Inlet
Put the generator set in level state. Fill the oil into the oilfilling inlet. At the time of checking the oil
level, it is necessary only to lightly insert the oil ruler. Please pay attention to that you should not
rotate the oil ruler.
Engine oil is the most important factor in deterrnining the life of your generator engine.If you
use poor engine oil or if you don't change the oil regularly,the piston and cylinder will wear
easily or seize up.Also,the life of the other parts in your engine such as bearings,and other
rotating parts will shorten considerably.
Although there is an alarm system to check for low oil pressure, it is always a good idea to check
the amount of oil inside the engine. lf the oil level is low, fill it before starting the engine. A good time
to drain the oil from the engine is when the diese! engine is still hot. If the engine is fully cooled, it is
more difficult to drain all the oil out or sorne impurities will remain in the engine.
WARNING: Don't fill engine oil when diesel is operating.
2-2.3 Check air filter
(1) Loosen the butterfly nut, take the cover of the air filter off and take the air filter element out.
Do not use detergent to wash the air filter element. When the performance of the engine decreases
or when the color of the exhaust gases is bad,exchange the filter element. Never start the engine
without the air filter as foreign objects may enter the intake and damage the engine.

or when the color of the exhaust gases is bad,exchange the filter element. Never start the engine
without the air filter as foreign objects may enter the intake and damage the engine.
(2) After replacing the air filter element, replace the cover and tighten the butterfly nut firmly.
2-2.4 Checking the generator welder
Before starting the generator,make sure the air switch is in the "off" position. Starting the generator
with the switch in the "on" switch is very dangerous. The generator should be grounded in order
to prevent electric shock. Use dry compressed air(with pressure about (1.96 x 105 Pa)to blow the
dust out in the electric control cabinet and at the surface of the generator.Check to see how clean
the surfacc of the sliding ring is. Check the pressure of the carbon bmsh.Also,check whether
the position of the carbon brush at the slide rig is correct and the fixture is reliable with a good
contact.
According to the electric wiring diagram, check to see whether the connecting wire is correct and
the connected place is firm. Use a 500 MΩmeter to measure the insulation resistance of the electri-
cal part.The resistance should be less than 2MΩ. When measuring devices ,make sure the capacitor
is turned off.Otherwise, it will burn tpe capacitor.(For silent set,the inspection may not be carried
out).
2-2.5 The fuel and oil in a new engine is drained before sold.
Before you start the engine, please fill the fuel tank snd oil first. Then,check to see if there are air
bubbles in the engine. If there are, follow these procedures.Loosen the connecting nut between the
oíl injection pump and oil pipe. Bleed the air from the system until there are no more bubbles. Then
replace the connecting nut and tighten it.
2-3 Checking the operation of the diesel engine
2-3.1 Low-pressure alarm system.
The diese! engines have a low-pressure sensor system where if the oíl pressure drops to low ,the
sensor will shut the engine off. The purpose of having this system is to ensure that the engine <loes
not seize up. If there is not enough oil in the engine,the temperature of the oil will be raised too
high.On the contrary,if there is too much oil in the engine,the engine oil can slow the engine down
considerably. (Note: The 2 GF-L model cannot automatically stop itself).
2- 3.2 How to open the case door/cover
(1) Open the case door:turn the handle counterclockwise and open the door. Do these checks daily.
7

EN
(2) Loosen the outer cover bolt of the air filter and outer cover of the oíl nozzle, and then check the
air filter.
(3) Check the outer cover of the oil nozzle. Loosen the butterfly nut and open the outer cover.
2-3.3 Engine break in
When you p urchase a brand new engine,the engine must be properly broken in. The break in period
is about 20 hours.
( l) Avoid overloading the engine when brand new.
(2) Change the engine oil according to specifications. An oil change for a brand new engine is about
20 hours or every month,an older engine, the oil change is about 100 hours or three months.
2-4 Starting the generator set
2-4. 1 Manual starting.
Start the engine in accordance with procedures below:
(1) Put the fuel switch in the "ON" position.
8

(2) Tum the handle of the engine to the "RUN" position.
(3) Pull the recoil starter handle out until you feel resistance. It will reset to its original position
automatically. The handle should be reset into its recoil device slowly to prolong the life of the life
of the engine starter.
(4) In cold climate, it is difficult to start the engine. To remedy this, pull the rubber plug out from the
rocker of the diesel engine and fill 2 ml of engine oil. Before starting, put the rubber plug back in
place. If you don't put the rubber plug back in place, rain, dust and other dirt can enter into the
diesel engine. It will cause the parts inside the diesel engine to wear quickly and lead to engine
failure.
2-4.2 Electric starting
The procedures for preparing to start eh engine are the same as the manual starting engine.
2-4.3 Battery
1. Insert key into ignition and put it in the "off' position.
2. Put the speed handle the "Run" position.
3. Tum the start switch clockwise to the "START" position; To set the silent type, first turn it clockwi-
se to the "RUN" (ON) position for 1-2 seconds. The electromagnetic iron will be triggered, now tum it
clockwise to the "START" position.
4. After the diesel engine is started, remove your hand from the switch handle; the switch will auto-
matically reset itself to the "ON" position.
5. If the engine is not starting after 10 sec-onds of cranking, wait about 15 seconds before trying it
again. If you crank to long, the voltage of the battery will drop. This can lead to improper ignition.
When the diesel engine is operating, let the ignition retain on the'

EN
NOTE: If you crank the starter to long, the battery may be drained too much to provide enough
energy for proper engine ignition. Also, when the diesel engine is operating, let the key retain in the
"ON" position.
Check the height of the electrolytic solution in the battery once a month. lf the level of the liquid
drops to low, fill it with distilled water until it reaches the high mark. lf there is not enough elec-
trolytic solution, then the diesel engine cannot be started. 1t is important to keep the liquid level
between the high and low limits.
If the level in the battery is too high, the liquid may flow out and end up on surrounding parts resul-
ting in corrosion of these parts.
NOTE: Avoid too much or to little of electrolytic solution. Check and fill it once a month.
2-5 Proper operation of the generator set
2-5.1 Operating the diesel engine
1. Pre-heat the diesel engine for 3 minutes under no load conditions.
2. First check the height of the lubricating oil level, if it is low, refill it. Our diesel engines are equi-
pped with an alarm system that will notify you if the oil pressure is to low. The alarrn system will shut
down the engine if the oil pressure is to low.
3. Do not adjust the speed limit regulation nut or the fuel adjustment bolt. These bolts have been set
by the factory already, changing them will aff ect the porperties of the engine performance.
2-5.2 Checks during engine operation
1. Check to see if there are abnormal noises.
2. Check to see if the performance is good or bad.
3. Check the color of the exhaust gases (whether it is too black or too white). lf any of these condi-
tions exist, stop the engine and find the cause of the problem. lf no problems are found, please
contact your local dealer or our nearest company branch.
2-6 Loading
2-6.1 Load conditions
Exert loads in accordance with the specified
parameters.
2-6.2 Output of electricity
1 . Raise the revolutions per minute (turn the speed handle to the max setting) of the generator to
get the maximum power out of the generator. If not, the automatic voltage regulator device will
excite and doing this for long periods of time will cause the capacitar to burn.
2. For the rated speed of the generator, please refer to Chapter 1, ítem 1-1 technical specification
and data.
3. Observe the pointer of the voltmeter, it should point to 220V ± 5 % (50Hz). (For 60Hz set, it will be
240V ± 5% ). This is the reading of the voltage at the ac socket.
CAUTION: Do not start more than two machines at the same time. The machines should be started
one ty one. Do not use the floodlight at the same time when using other devices.
4. When connecting devices to the generator, make sure to connect these devices in order. Connect
the large loads onto the generator first. If everything is functional, smaller loads can then be added.
If the generator shuts off, it may be because the load being drawn by all the various devices are too
high. In this event, decrease the number of small devices until everything is functional. The total
drawn power should not exceed the maximum output power of the generator. Please see Table 1-1
for technical specifications of what the generator can output. In order to reset the generator after
overdrawn power, let it sit for several minutes. If the indication of the voltemeter is too high or too
low, adjust the speed accordingly. If there are problems, stop the generator immediately and fix the
issue.
5. Make sure you are operating your generator in a well-ventilated area. The generator should never
be covered with anything to prevent overheating the generator.
2-6.3 Charging the battery
1. For the electric starter generator, the 12V battery is automatically charged through the regulator
on the generator when it is running.
2. If the generator is not used for long periods of time, the battery should be disconnected to avoid
energy loss from the battery.
3. Do not connect the negative and positive terminals of the battery together at any time. Doing so
will damage the battery.
4. Do not reverse the polarities when attaching the battery cables to the battery. Doing so will
damage both the battery and the electric starter.
5. When charging the battery, the battery produces flammable gases. Do not smoke, flames, and
sparks get near the battery while it is charging as this may cause a fire. To avoid sparking while
connecting the cables to the battery, first, connect the cables to the battery then to the motor. To
disconnect battery cables, first disconnect the motor end of the cable.
2-7 Stopping the generator
1. Take the electrical load off the generator.
2. Tum generator air switch off.
3. Put the speed handle in the "RUN" position and let the engine run for 3 minutes after unloading.
Do not stop the diesel engine immediately let it warm down. Stopping the diesel engine suddenly
may raise the temperature of the engine abnormally and lock the nozzle and damage the diesel
engine.
4. Press down on the brake handle.
