CHAPTER 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 or
equipment damage.
2-1.1 Fire prevention
The proper fuel for the diesel generator set is light diesel fuel. Do not use
gasoline, kerosene 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 1.5 meters away from buildings and or other equipment. Always operate
your diesel generator on a level site. If 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 monoxide. Never operate your generator in places with
poor ventilation. In 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 burns
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 Electric 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. Use a lead to
connect the grounding end of the generator to the grounding surface of choice.
Please refer to Fig. 2-1 before beginning to use the electric generator.
Fig. 2-1
Note: When connecting 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 functions of the generator before using this
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 also known as battery acid contains sulfuric
acid. In order to protect your eyes, skin, and clothing, wears protective gear
when working with the battery. If you come in contact with the electrolytic 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
2-2.1 Fuel choices and fuel treatment
Fuel tank
Use only light diesel fuel. The fuel should be filtered clean. Never let dust and
water mix with fuel in the fuel tank. Otherwise it will clog the fuel lines and oil
nozzles. It may also damage your pressure pump.
Note: It 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 smoking 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 Filling engine oil
Remove the dipstick from the engine
Make sure the generator is on level ground, and fill the engine with 15W40
engine oil. Put the dipstick back into the hole to check the engine oil level.
Engine oil is the most important factor in determining 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. If the oil level is low, fill
it before starting the engine. A good time to drain the oil from the engine is
when the diesel engine is still hot. If the engine is fully cooled, it is more difficult
to drain all the oil out or some impurities will remain in the engine.

2-2.3 Checking the 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) After replacing the air filter element,
replace the cover and tighten the
butterfly nut firmly.
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 surface of the sliding ring is. Check the pressure of the
carbon brush. Also, check whether the position of the carbon brush at the slide
ring 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 M Ωmeter to measure the insulation resistance of the electrical part.
The resistance should be no less than 5M Ω. When measuring devices, make
sure the AVR is turned off. Otherwise, it will burn the AVR. (For the low noise
set, the inspection may not be performed).
2-2.4 The fuel and oil in a new engine is drained before sold. Before you start
the engine, please fill the fuel tank and engine 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 fuel injector pump and fuel 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.
H.D diesel engines have a low-pressure sensor system where if the oil pressure
drops too low, the sensor will shut the engine off. The purpose of having this
system is to ensure that the engine does 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.
2-3.2 How to open the case door/cover
(1) Open the case door: Pull the
handle outward and open the
door. Do these checks daily.
(2) Loosen the outer cover bolt of
the air filter and outer cover of
the oil 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 purchase a brand new engine, the engine must be properly broken
in. The break in period is about 20 hours.
(1) 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 Starting.
Start the engine in accordance with procedures below:
(1) Open the front door to put the speed handle
to right side, namely “on” position.

2. Put the speed handle in the “Run” position.
3. Turn the start switch clockwise to the “START” position.
4. After the diesel engine is started, remove your hand from the switch handle;
the switch will automatically reset itself to the “ON” position.
5. If the engine is not starting after 10 seconds of cranking, wait about 15
seconds before trying it again. If you crank too 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 “ON” position.
Note: If you crank the starter too 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.
Important Notice：
All of our units come with a
maintenance free battery. You do not
need to add any battery acid.
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
equipped with an alarm system that will notify
you if the oil pressure is too low. The alarm
system will shut down the engine if the oil
pressure is too low.

3. Do not adjust the speed limit regulation bolt or
the fuel adjustment bolt. These bolts have been
set by the factory already, changing them will
affect the properties 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).
If any of these conditions exist, stop the engine and find the cause of the
problem. If 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 AVR to burn. For the rated speed of the generator,
please refer to Chapter 1, item 1-1 technical specification and data.
2. Observe the pointer of the voltmeter; it should point to 240 V 5% (60Hz).
Meanwhile put the switch in the GEN (generator) position. The AC voltage
from the socket of the power supply can be output.
3. 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 voltmeter is too high or too low, adjust the speed
accordingly. If there are problems, stop the generator immediately and fix
the issue.
4. During operation, the generator should be in a place that has very good
ventilation. Never cover the engine to solve a ventilation problem, as this
will damage your equipment.
Note: Do not start more than two devices simultaneously. Each
device should be started one by one to prevent overloading the
generator.
The generator should be running at 3600 revolutions per minute
in order to achieve the (60 Hz) frequency. The speed of the
engine can be adjusted from the speed governor.

OPERATING THE DIESEL GENERATOR
21
2-6.3 Charging the battery
1. For the electric starter on the generator sets, the 12V battery is automatically
charged through the regulator on the side of the engine 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 and cause serious injuries.
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, let 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. 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.
Note:
1. If you cannot stop the engine with a
load on it, then remove the load first
than stop the engine.
2. Press down on the brake handle.
3. If equipped with an electric starter, turn
the key to the “Off” position.
4. Put the fuel handle to the “S” position.
