CHAPTER 2 OPERATING THE DIESEL GENERATOR
2-1 Main points of safety during operation of the welder generator set.
In order to operate the welder 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 diesel 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 1.5 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 welding generator.

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 re
g
ulated 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, wear 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 operation2-2 Preparation before operation
2-2.1 Fuel choices and fuel treatment2-2.1 Fuel choices and fuel treatment
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.
Air filter element
Note: It is dangerous to overfill the fuel tank.
Never exceed the red piston in the filter.
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.
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)
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.

The lubricating oil must be CC or CD grade.
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.
