make the engine run longer.
lf you have any questions or suggestions about this manual, please contact us or dealer. User
should pay attention to that with the improvement of our products the descripition in this manual
may differ from practical products.
2. SAFETY PRECAUTIONS
Please make sure to follow each precaution carefully.
EXHAUST PRECAUTIONS
• Never inhale exhaust gas, lt contains carbon monoxide, a colorless, odorless and extremely dan-
gerous gas which can cause unconsciousness or death.
• Never 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.
• lf fuel is spilled, wipe it away carefully and wait until the fuel has dired 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 drybrush, twigs, clothes, bags, or other flammable materials
• Keep the engine at least 3 feet (1 meter) away from buildings or other structures.
• Keep the engine away from flammables and other hazardous materials (trash, rags, lubricants,
explosives).
PROTECTIVE COVER
• Place the protective covers over the rotating parts.
lf rotating 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, loase gravel, etc.
• Operate the engine on a level surface.
lf 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.
• Do not move the engine while it is in operation.
• lf 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 necessery.
• Check the fuel level and refill if necessary. Take care not to overfill the tank.
• Wear snug fitting working clothes when operating the engine.
Loase aprons, towels, belt, etc., may be caught in the engine or driving train causing a dangerous
situation.

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.
• Do not move the engine while it is in operation.
• lf 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 necessery.
• Check the fuel level and refill if necessary. Take care not to overfill the tank.
• Wear snug fitting working clothes when operating the engine.
Loase aprons, towels, belt, etc., may be caught in the engine or driving train causing a dangerous
situation.

4. OVERALL DIMENSION AND INSTALLATION lnstallation
(1) There must be a light 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,
(5) Be sure that belt is tightened properly.
lf the belt is fixed too tight, the engine will be overloaded while starting, the belt be drawn longer,
and the engine may be damaged.
lf the belt is fixed too loose, the belt will slip at high speed and high load.
1-2.3 Allowed distance between belt wheel and engine

Thank you for purchasing products from our company.
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, soli-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
before running the enqine for correct operation.
Follow the operating requirement in the manual to keep your engine in best working condition and
make the engine run longer.
lf you have any questions or suggestions about this manual, please contact us or dealer. User
should pay attention to that with the improvement of our products the descripition in this manual

2. SAFETY PRECAUTIONS
Please make sure to follow each precaution carefully.
EXHAUST PRECAUTIONS
• Never inhale exhaust gas, lt contains carbon monoxide, a colorless, odorless and extremely dan-
gerous gas which can cause unconsciousness or death.
• Never 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.
• lf fuel is spilled, wipe it away carefully and wait until the fuel has dired 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 drybrush, twigs, clothes, bags, or other flammable materials
• Keep the engine at least 3 feet (1 meter) away from buildings or other structures.
• Keep the engine away from flammables and other hazardous materials (trash, rags, lubricants,
explosives).
PROTECTIVE COVER
• Place the protective covers over the rotating parts.
lf rotating 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, loase gravel, etc.

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,
(5) Be sure that belt is tightened properly.
lf the belt is fixed too tight, the engine will be overloaded while starting, the belt be drawn longer,
and the engine may be damaged.
lf the belt is fixed too loose, the belt will slip at high speed and high load.

Thank you for purchasing products from our company.
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, soli-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
before running the enqine for correct operation.
Follow the operating requirement in the manual to keep your engine in best working condition and
make the engine run longer.
lf you have any questions or suggestions about this manual, please contact us or dealer. User

2. SAFETY PRECAUTIONS
Please make sure to follow each precaution carefully.
EXHAUST PRECAUTIONS
• Never inhale exhaust gas, lt contains carbon monoxide, a colorless, odorless and extremely dan-
gerous gas which can cause unconsciousness or death.
• Never 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.
• lf fuel is spilled, wipe it away carefully and wait until the fuel has dired 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 drybrush, twigs, clothes, bags, or other flammable materials
• Keep the engine at least 3 feet (1 meter) away from buildings or other structures.
• Keep the engine away from flammables and other hazardous materials (trash, rags, lubricants,
explosives).
PROTECTIVE COVER
• Place the protective covers over the rotating parts.
lf rotating 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, loase gravel, etc.
• Operate the engine on a level surface.
lf 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.
• Do not move the engine while it is in operation.
• lf 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 necessery.
• Check the fuel level and refill if necessary. Take care not to overfill the tank.
• Wear snug fitting working clothes when operating the engine.
Loase aprons, towels, belt, etc., may be caught in the engine or driving train causing a dangerous
situation.

lf your engine is still a newer one, its life would be shortened for over-load.
At first 20 hours the engine must be started and stopped according to test run method.
Avoid over-load:
Avoid over-load during test run.
Change machine oil regularly:
Change machine oil once every twenty hours or at the end of first month at primary running time
and then once every three months or 100 hours.

NOTE: WHEN THE ENGINE IS RUNNING, DO NOT PULL THE RECOIL HANDLE OTHERWISE THE
ENGINE MAY BE DAMAGED.
16
17
2-3.2 Motor-driven type start
(1) start
The preparation of moter-driven start type is same as manual type (Recoil type).
CD Open the fuel cock.
® Set the speed governor lever at "start" position.
® Turn on the start switch toward clockwise to "start" position.
© lf the engine is started, take your hand away from key switch immediately.
@ lf the engine do not start after 10 seconds, wait for a while (about 15 seconds) then start again.
(2) Accumulator
CD Check the liquid level in accumulator every month, if the level is lower than the low limit mark,
refill distilled water up to the upper limit mark.
lf the liquid in the accumulator is not enough, the electric motor will not run for too little electric
current. So, keep the liquid level between upper and low limit marks.
The liquid will splash on near parts (which will be spoiled) if it is too much in the accumulator.
Start key Switch
lf the run time of motor is too long, the voltage of accumulator
will drop and the motor may be damaged.
Keep key switch at "ON" position when the engine is running
18
2-3.3 Aided start
lf the engine is difficult to start in winter, take off the rubber seal plug and then fill 2cc machine oil
into the hole.
Notice: Engines supplied to the torrid zone will not attach the rubber plug. (a solid plug is presented
only)
WARNING! Do not use volatile liquid as fuel, such as gasoline etc, and do not take away the air
cleaner for easy start of the engine, if you do so, it may cause explosion.
Do not pull out the plug unless filling oil. lf plug is not at its correct position, rain, dust or other
impurity may be sucked into the engine to cause serious failure or to damage engine parts.
2-4 Run and Stop of the Diesel Engine
2-4.1 Run of the engine
(1) Preheat the machine for three minutes at no load
(2) Set the speed governor lever of the engine at required speed position.
Use the speed governor lever to control the speed of engine.
Do not loasen or readjust the limit screw of speed or oil-filling limit screw, otherwise the performan-
ce of the machine may be changed.
19
Oil filling limit screw
2-4.2 Check when the machine is running:
(1) Whether there is abnormal sound and vibration?
(2) Whether combustion is not good or overspeed?
(3) Whether the color of exhaust gas is normal (black or too white)?
lf any of above phenomena is detected, stop the engine immediately and contact your local dealer.
2-4.3 stop of the engine
(1) At first set the speed governor lever at low speed position before stopping the engine, and then
run the engine at no-load for three minutes.
(2) Set the speed governor lever at "stop" position.
Decrease the load gradually when stopping the engine. Sudden stop of engine will cause abnormal
increasement of temperature.
Do not stop engine with decom pression lever.
