3. PREPARATION BEFORE OPERATION
3.1 Prepare the Fuel, Lubricating Oil and Cooling Water
3.1.1 Fuel
(1) To keep the engine in best working condition, be sure to use the recommend-
ed fuel: light diesel oil JIS K2204 (GB252-87)
However, be sure to choose the appropriate brand for the light diesel oil
according to actual ambient temperature.
Light diesel oil brand:
Temperature:
(2) Fuel usage
The fuel with water or dust contaminated will cause the rough running of the
engine. Be sure to use the clean container for storing the fuel, meanwhile, the
container must be stored at a clean and dry place. Then suck out the upper level
clean fuel with a pump as below figure.

OPERATION NOTE
The improper fuel cannot make the engine
achieve the best performance, and even
cause the fault of the part.
Only use the upper level clean fuel. Do not
use the lower deposited fuel.
3.1.2 Lubricating oil
(1) Do use L-ECD grade oil; the quality index is 15W/30 or 15W/40.
(2) The usage of lubricating oil:
A. Carefully store and use the lubricating oil. Avoid any dust and impurity in the oil.
B. Do not mix two different type lubricating oil, otherwise the lubrication
performance will be decreased.
8.3 The adjustment of the fuel injector
The test and regulation of the injector should be done on the fuel injector test bed.
Its purpose is regulating the oil pressure and watching the atomization quality and
eliminating the fault.
1. Pump the oil by using the hand pump unit the injection pressure is 14 0.5Mpa,
check the Injection condition and atomization quality whether accords with
injection requirement. If there is oil leakage or dropping in the injector, you should
remove the fuel injecting assembly to clean or repair it until make injection up to
requirement.
2. The adjustment of injection pump.
Pump the oil by using the hand pump. When the reading of the fuel injection
starting pressure can't reach 13Mpa, you can remove the injection assembly by
increasing the thickness of the adjustment shims to improve the injection pressure
until the pressure reading is up to standard. If the reading is over 13Mpa, you
should reduce the thickness of the adjustment shims.
8.4 The adjustment of the injection pump
Injection pump has been tested and adjusted before leaving from the factory. If
you need to readjust it, you should perform the adjustment on the test bed
according to relative regulations.
8.5 The adjustment of the V belt
As shown in the figure, make the tension check in the arrowhead direction. As to
new products, put a 100N force on the it and loosen the belt until looseness
degree reaches 4 5 mm. Under the normal condition, put on a 100N force until
the looseness degree is 6 7mm. If you put on a 100N force but the looseness is
no less than 9mm, replace the V belt.
