Do not accelerate or overload the engine abruptly at the 
first 50 hours when running a new one.

4.4The notes items of date running

Following below points while inspecting the running state of engine

4.4.1 Exhaust and smoke

If there is much smoke, you should stop the engine. The smoke is the symbol of 

the overload or broken. That will shorten the life of the engine. You should avoid it.

4.4.2Abnormal noise or shock

According to the structure of the enegine

it will produce resonance at rated 

speed

the resonance will result in shock and abnormal noise, don't run the 

engine at the rotation speed, otherwise the enegine will be damaged.

4.4.3Alarm lamp

If the alarm lamp is light, just cut the power output switch, remove the load, then 

reduce the rotation speed, and stop the engine and check it.

4.4.4 Gas leakage, fuel leakage, water leakage and the bolt loose

Check the external parts, be sure that the enegine is no leakage, no loosen bolt.

4.4.5The oil level is too low.

You should check the oil level of oil sump. And add the oil before it drops to the 

lowest limit

4.4.6The fuel level of the fuel tank is too low

Check the fuel level of the fuel tank, and add the oil before it drops to the lowest 

limit. 

4.5 Stop the engine

Stop the engine as following.

4.5.1 Cut off the clutch or load switch to cut off the outside load. 

4.5.2 Reduce the speed to the idle speed gradually, running about 5 minutes, 

make the temperature of the heated parts lower.

4.5.3 Turn the start key to the "off" position, the engine crankshaft stop rotating. 

Take off the key and put it in a safety place.

4.5.4 Turn off the battery switch.

4.5.5 Turn off the switch of the fuel tank

 If the starting switch is on "off" position, but the engine is not stopped, you should 

turn off the switch of fuel tank, cut off the fuel supply, the engine will stop quickly.

When the engine is running, do not cut off the 
switch or make a short circuit. Otherwise it will 
produce strong spark. Abnormal electric surge will 
result in system fault. 

After running, do not stop urgently. Or it will make the 
engine temperature zoom, it easy cause adhibit the 
cylinder, burn the crankshaft, damage the engine.

4.6 Notice for the long-time storage 

If you want to store the engine for long time, please pay attention to the following 

points. 

4.6.1 The draining of the cooling water: If there is no antifreeze in the cooling 

water, make sure drain the cooling water completely. To prevent frost crack the 

engine, cylinder cover, radiator, oil radiator etc,.in the cold winter. 

Screw out the cover of the radiator.

Open the drain piston or the rubber tube at the bottom of the water tank.

Screw off the drain piston at the bottom of the water tank.

After drain out the cooling water, reinstall every part.

4.6.2 Clean outer parts, oil draining, oiling

Clean the dust and oil dirty on the case of the engine.

To prevent the condensation, you should drain the fuel completely or top up the 

fuel tank.

Add lubricant oil to the supporting and connecting point of the timing system. 

4.6.3 Waterproof and dustproof

Cover the whole diesel unit with sealed plastic jacket, prevent for the water and 

the dust.

Store the engine in a ventilated place, far away from the moist and dusty place. 

4.6.4 Measures for the battery discharge itself.

Cut off the unit's switch or ground wire (connect the cathode to the ground)

Charge for the unit once a month, equalize the unit discharge itself. 

4.6.5 Check the unit after the long-time storage

If you want to start the long-time storage engine, you should perform the 

preparative procedure "before the operation" on chapter 3.

Prevent hurted when draining the hot water. Drain hot 
water until temperature is lower. The vapour or hot 
water will scald you.
