INTRODUCTION
Thank you for purchasing products from our company.
Direct injection combustion chamber.
Recoil-type manual starter and optional electric starter.
Force air cooling system.
The fan cover made of low noise composite steel plate.
Series air cooling, direct injection. 4-stroke diesel engines are such a type engine of saving on material
and energy. The series engines are small, light. They’re easy to maintain, and convenient to move.
They are used widely as a power for industrial, agricultural, machinery tool such as irrigation, spray,
rice-transplanting, threshing, grass-cutting, Soil-sampling, and also used in vibration rammer, shock
rammer, marine engine, light-type transport vehicle, movable-type compressor, light-type generation
set, car washing machine, tillage machinery etc..
This operating manual will tell you how to operate and maintain your series engines. Please read it be -
fore running the engine for correct operation. Follow the operating requirement in the manual to keep
your engine in best working condition and make the make the engine run longer. If you have any ques-
tions or suggestions about this manual, please contact us or dealer. User should pay attention to that
with the improvement of our products the description in this manual may differ from practical products.
Please make sure to follow each precaution carefully.
EXHAUST PRECAUTIONS
ever inhale exhaust gas, it contains carbon monoxide, a
colorless, odorless and extremely dangerous gas which can
cause unconsciousness or death.
ever operate the engine indoors or in a poorly ventilated
area, such as a tunnel or cave, etc. exercise extreme care
when operating the engine near people or animals.
Keep the exhaust pipe free of external objects.
REFUELING PRECAUTIONS
Be sure to stop the engine prior to refueling.
Do not overfill the fuel tank.
If fuel is spilt, wipe it away carefully and wait until the fuel
has dried before starting the engine.
When changing oil, make sure that the fuel cap is secure to
prevent spillage.
FIRE PREVENTION
Do not operate the engine while smoking or near an open
flame.
Do not use the engine around dry brush, twigs, clothrags,
or other flammable materials.
Keep the engine at least 3 feet(1 meter) away from build-
ings or other structures.
Keep the engine away from flammables and other haz-
ardous materials(trash, rags, lubricants, explosives).

PROTECTIVE COVER
Place the protective covers over the rotating parts. If rotat-
ing parts, such as the driving shaft, pulley, belt, etc. are
left exposed, they are potentially hazardous. To prevent
injury, equip them with protective covers or shrouds.
Be careful of hot parts. The muffler and other engine parts
become very hot while the engine is running or just after it
has stopped. Operate the engine in a safe area and keep
children away from the running engine.
SURROUNDINGS
Operate the engine on a table, level surface free of small
rocks, loose gravel, etc.
Operate the engine on a level surface. If the engine is
tilted, fuel spillage may result.
NOTE: Operating the engine at a steep incline may cause
seizure due to improper lubrication even with a maximum
oil level.
Be careful of fuel spillage when transporting the engine.
Tighten the fuel tank cap securely and close the fuel
strainer cock before transit.
If the engine will be transported over a long distance or on
rough roads, drain fuel off from fuel tank to prevent fuel
leakage.
PRE-OPERATION CHECKS
Carefully check fuel pipes and joints for looseness and
fuel leakage. Leaked fuel creates a potentially dangerous
situation.
Check bolts and nuts for looseness. A loose bolt or nut
may cause serious engine trouble.
Check the engine oil and refill if necessary.
Check the fuel level and refill if necessary. Take care not
to overfill the tank.
Wear snug fitting working clothes when operating the en-
gine.
Loose aprons, towels, belt, etc., may be caught in the en-
gine or driving train causing a dangerous situation.

OVERALL DIMENSIONS
INSTALLATION
1) There must be a tight stationary foundation for diesel engine to avoid vibration or movement
when the engine is running.
2) Be sure that the center position of output axle is correct.
3) Check whether calibration between axle hole of belt wheel and keyway shaft is correct and
whether the tighten screw nut of belt wheel is tightened up.
4) When the engine is matched with other belt-driving machine, the diameter of driving wheel
must be in harmony with the speed of diesel engine and the size of axle wheel of the equipped
machine. Otherwise it will directly influence working condition of diesel engine, the life of the
engine and the efficiency of working machine.
The diameter of driving wheel (belt wheel) can be calculated as follow:
Diameter of engine driving wheel = (Diameter of axle wheel of working machine x Speed
of working machine) / Diesel Speed
5) Be sure that belt is tightened properly.
If the belt is fixed too tight, the engine will be overloaded while starting, the belt will be drawn
longer, and the engine may be damaged. If the belt is fixed too loose, the belt will slip at high
speed and high load.

INSTRUCTIONS FOR SAFE OPERATION
The fuel must be filtered by silk fabric or settled for 24 hours before used. Do not add oil into
fuel tank or crank shaft case when the engine is running.
Burnable and explosive goods should not exist around the engine, and the place for installa-
tion should be plain and ventilated.
Do not touch muffler with your hand when the engine is running or just after it has stopped.
The diesel engine must be run under rated power and rated speed. If you detect abnormal
phenomenon, stop the engine immediately to check and remedy.
ew engine or newly maintained one must be run at low speed and low load at first 20 hours.
Do not allow to run it at high speed and full load.
