Safety information

Exhaust precautions

• Never inhale exhaust gas. It contains carbon monoxide, a colorless, odorless, and highly dangerous gas that can cause unconsciousness or death.
• Never operate the engine indoors or in poorly ventilated areas such as tunnels, caves, or enclosed spaces.
  • Exercise extreme caution when operating the engine near people or animals.
• Keep the exhaust pipe free from obstructions.

Refueling precautions

• Stop the engine before refueling.
  • Do not overfill the fuel tank.
• If fuel is spilled, wipe it up immediately and wait for it to dry completely before starting the engine.
• When changing the oil, ensure that the fuel cap is secure to prevent spillage.

Fire prevention

- Do not operate the engine while smoking or near open flames.

• Avoid using the engine near dry brush, twigs, rags, or any other flammable materials.
• Maintain a distance of at least 3 feet (1 meter) between the engine and any buildings or structures.
• Keep the engine away from flammable materials such as trash, rags, lubricants, or explosives.

Protective cover

• Ensure that protective covers are placed over all rotating parts. Exposed rotating components, such as the driving shaft, pulley, or belt, pose a hazard and should be shielded with protective covers or shrouds.
• Be cautious of hot parts. The muffler and other engine parts can become extremely hot during operation or shortly after stopping the engine.
• Operate the engine in a safe area and keep children away from the running engine.

Surroundings

• Operate the engine on a stable, level surface free of debris such as small rocks or loose gravel.
  • Always keep the engine on a level surface. If the engine is tilted, fuel spillage may occur.
• Note: Operating the engine on steep inclines may result in engine seizure due to improper lubrication, even if the oil level is at maximum.
• Take care to avoid fuel spillage when transporting the engine. Secure the fuel tank cap and close the fuel strainer cock before moving.
• Do not move the engine while it is running.
• If transporting the engine over long distances or on rough roads, drain the fuel from the tank to prevent leakage.

Pre-operation checks

• Thoroughly inspect fuel pipes and joints for looseness or fuel leaks, as leaked fuel can create a hazardous situation.
• Check all bolts and nuts for tightness. Loose bolts or nuts can lead to serious engine issues.
• Check the engine oil and refill if necessary.
• Check the fuel level and refill if needed, taking care not to overfill the tank.
• Wear snug-fitting work clothes when operating the engine. Avoid wearing loose garments like aprons, towels, or belts, as they may get caught in the engine or drive components, leading to a dangerous situation.

Installation

1) Ensure the diesel engine is mounted on a solid, stationary foundation to prevent vibration or movement during operation.
2) Verify that the center alignment of the output axle is correct.
3) Check if the calibration between the axle hole of the belt wheel and the keyway shaft is accurate and ensure that the tightening screw nut of the belt wheel is securely fastened.
4) When the engine is connected to other belt-driven machinery, ensure that the diameter of the driving wheel is compatible with the diesel engine's speed and the size of the axle wheel of the connected machine. Failure to do so can negatively affect the engine's performance, reduce its lifespan, and decrease the efficiency of the connected equipment.

The diameter of driving wheel (belt wheel) can be calculated as follow:

Diameter of engine driving wheel = (Diameter of axle of wheel of working machine * speed of working machine) / Diesel speed

5) Ensure the belt is properly tensioned.

- If the belt is too tight, the engine will be overloaded during startup, the belt will stretch excessively, and the engine may be damaged.

- If the belt is too loose, it will slip during high-speed or high-load operation, reducing performance and potentially causing damage.

Allowed distance between belt wheel and engine:

- The V-axle wheel groove should be as close to the engine as possible. The allowed distance "L" is specified in the table below.

- Note: The meaning of "L" is shown in the figure above. Please contact us or your dealer if you have any questions.

CHAPTER 2: Operation of diesel engine

Safety precautions:

• Filter fuel using silk fabric or let it settle for 24 hours before use. Do not add oil to the fuel tank or crankshaft case while the engine is running.
• Keep flammable and explosive materials away from the engine. Ensure the installation area is flat and well-ventilated.
• Avoid touching the muffler when the engine is running or just after stopping, as it can be very hot.
• Operate the engine at its rated power and speed. If any abnormal conditions occur, stop the engine immediately to inspect and resolve the issue.
• For new or newly serviced engines, run at low speed and low load for the first 20 hours. Avoid operating at high speed or full load during this break-in period.

Choice of fuel, oil and preparation before start

Choice of fuel:

Use only light diesel fuel for the diesel engine. For summer, use No. 0 diesel; for winter, use No. -10 or No. -20 diesel, depending on the temperature. Ensure no dust or water enters the fuel or fuel tank.

Fuel capacity: 5.5 liters

Caution: Do not fill the fuel above the red mark.

A B A - cap B - red mark Stop Start

Air filter core:

Do not wash the air filter core, as it is a dry-type filter. Replace the core if engine performance decreases or if the exhaust color appears abnormal. Never operate the engine without the air filter core installed.

Oiling screw plug

In winter, if the engine is difficult to start, remove the plug and add 2cc of lube oil into the hole, then securely reinsert the plug. Ensure the plug is tightly fastened. If the plug is left out, the engine may absorb dust and become damaged.

Fuel and oil preparation

The fuel and engine oil were drained before shipment from the factory. Before refilling fuel and starting the engine, check the fuel pipeline. If there is air in the pipeline, it must be removed. To do this, loosen the nut at the connection between the injection pump and the fuel pipe, and bleed the air from the system until no bubbles are visible in the fuel.

Oil inlet:

Place the engine on level ground before filling oil into the inlet. When checking the oil level, insert the dipstick into the inlet gently without twisting it.

Ba sure to use SAE 10W30, API grade CD or higher.

Engine break-in period

If your engine is new, its lifespan could be shortened by overloading. During the first 20 hours of operation, follow the test run procedures for starting and stopping the engine.

- Avoid overloading: Do not overload the engine during the test run.

Oil change schedule

• Change the engine oil after the first 20 hours of operation or at the end of the first month during the break-in period.
• After that, change the oil every three months or every 100 hours of use, whichever comes first.

5) Pull the rope hard and fast. Pull it all the way out. Use two hands if necessary.

6) The engine should start. If the engine does not start, start again from step 3.

Motor-driven type start

1. Motor start

The preparation of motor-driven start type is same as manual type (Recoil type).

1) Open the fuel cock.
2) Set the speed governor lever at "start" position.
3) Turn on the start switch toward clockwise to "start" position.

Turn the start key

4) When the engine is started, take your hand away from key switch immediately.
5) If the engine does not start after 10 seconds, wait for a while (about 15 seconds) then start again.

NOTE:

• If the run time of motor is too long, the voltage of accumulator will drop and the motor may be damaged.
• Keep key switch et• ON n position when the engine is running

2. Accumulator

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.

H L

H - high

L - low

If 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.

Aided start

If the engine is difficult to start in winter, take off the rubber seal plug and then fill 2cc machine oil into the hole.

Notice:

Engine supplied to the torrid zone will not attach the rubber plug.(a solid plug is presented only)

Cylinder head cover

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, if 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.

Change the core of air filter

Core of air filter

- Change every 6 months or 500 hours (earlier if necessary).

Important note: Do not use detergent to clean filter core. Use a soft brush instead.

The core of filter obstruction means that the air in the combustion chamber will decrease, and then the output of engine decreases, and consumption of fuel and lubricant increases. It is also difficult to start the engine. Clean the core of filter regularly.

Storage for a long period

Follow these steps if storing the engine for an extended period:

1) Run the engine for three minutes, then stop it.
2) Drain the lubricant while the engine is still warm, and refill with new machine oil.
3) Remove the rubber plug on the rocker shaft cover, add about 2cc of lubricant, and then replace the plug.
4) For recoil start type:

- Push down the decompression lever to the non-compression position, then pull the recoil starter two or three times.

For motor-driven start type:

- Set the decompression lever to the non-compression position, then rotate the engine for two to three seconds using the start key (do not run the engine).

5) Pull up the decompression lever and slowly pull the recoil starter until resistance is felt (this indicates the compression stroke, where the intake and exhaust valves are closed, helping to prevent engine rust).
6) Clean off any dirt and oil from the engine, and store it in a dry place.

CHAPTER 5: Malfunction and remedy of diesel engine

Cause and remedy for the engine not being started

CAUSE	REMEDY
The weather is cold, machine oil becomes more adhesive	Fill machine oil into crankshaft case after preheated. Fill machine oil into the inlet manifold. Disassemble the connection belt of matching machine and then start the diesel engine. Stop the engine when the engine becomes hot and reassemble the belt. Start the engine again.
Malfunction of fuel system. The fuel is mixed with water	Clean fuel tank filter and fuel pipe, change fuel.
The fuel becomes thickened and is not easy to flow	Use the specific fuel.
There is air in the fuel system	Drain out the air and tighten each connector of fuel pipe.
Injection fuel is little or no, the spray is not good	Check the position of speed governor handle, clean spray nozzle, fuel pump, maintain or change the pump or nozzle if necessary.
Combustion is not complete	The spray nozzle is not good, delivery angle is not correct, gasket of cylinder head is leaky and the pressure of compression is not enough. Remedy with its cause.
Diesel fuel delivery is interrupted	Diesel fuel is too little in the fuel tank. Fill the fuel into the fuel tank. If the fuel pipe and fuel filter are obstructed or leaky, remedy them.
Compression pressure is not enough in the cylinder, the nut of cylinder head is not tightened or gasket of cylinder is damaged or leaky.	Tighten the nut of cylinder head, according to diagonal line sequence and standard requirement, check gasket of cylinder head once again after pre-running the diesel engine.
The gap of piston ring is too big because of water	Change the piston ring.
Each gap of piston rings lines up and causes leakage	Set each gap of piston at an angle of 120°.
The piston rings are stuck seriously or broken	Clean with diesel fuel or change rings.
Gas valves leakage	Grind the gas valves, if the vestige is too deep, please send it to factory for remedy.
The valve clearance is not correct	Adjust the clearance as specified.
The valve stem is clipped on guide pipe	Disassemble the gas valve and clean the stem and guide pipe.

Cause and remedy for not enough power of diesel engine

CAUSE	REMEDY
Malfunction of fuel system: parts obstruction of fuel pipeline and fuel filter	Check fuel switch, it must be opened fully. Clean fuel filter and fuel pipeline.
The pumping of fuel is not good	Maintain or change the damaged parts of fuel pump.
Malfunction of nozzle: injection pressure is not correct	Adjust the injection pressure.
Spray hole carbon deposit	Clean.
Needle valve adhered	Clean or change.
Fitting is too loose between needle valve and needle valve body	Change.
Air filter is obstructed	Disassemble to clean or change the core of filter.
Speed is not high enough	Check the speed of diesel engine with tachometer. Adjust the high-speed limit screw.

Cause and remedy for the engine stopping automatically

CAUSE	REMEDY
Malfunction of fuel system: No fuel	Add fuel.
Fuel pipeline or filter is obstructed	Maintain or clean.
There is air in the fuel system	Drain out the air.
Needle valve of nozzle adhered	Clean, grind the nozzle or change it if necessary.
Air filter is obstructed	Maintain or brush off.
The load increases suddenly	Decrease the load.

Cause and remedy for exhaust with black smoke

CAUSE	REMEDY
Overload	Decrease the load, if the working machine is not properly matched, change it.
Fuel injection is not good	Check the injection pressure and spray condition and correct it. Or change the nozzle if it is damaged.
Air is not enough or leaky	Clean the air filter, check the cause of leakage and remedy.

Cause and remedy for exhaust with blue smoke

CAUSE	REMEDY
There is machine oil in the cylinder	Check oil level, drain away the unnecessary machine oil.
Piston ring is clipped or worn, and its springiness is not enough, or each gap of ring turns to the same direction to make the machine oil go up	Check, change the piston ring, and cross each gap position.
The gap is too big between piston and cylinder	Remedy or change.
Valve and guide are worn	Change.

Cause and remedy for exhaust with white smoke

CAUSE	REMEDY
There is water in diesel fuel	Clean the fuel tank and diesel filter, change diesel fuel.

Methods and positions of stopping to check when the engine is malfunctioning

CAUSE	REMEDY
Speed is sometimes high, sometimes low	Check the speed governor system whether it is nimble. Check whether there is air in the fuel pipeline.
Abnormal sound suddenly appears	Check each motional part carefully.
Exhaust with black smoke suddenly	Check fuel system, especially nozzle.
There is a metal knocking sound rhythmically in the cylinder	The fuel delivery angle is too big. Adjust it.
