4.3 Check engine during the running

Make sure there is no abnormal case during the running referring to following 
items.

1. Whether the color of the exhaust gas is normal or not.

If the engine exhausts black smoke continuously, stop to check it at once. If ignore 
this symptom, it leads to engine run in a bad condition.

It will shorten the service life of the engine under the overload.

2. The abnormal working sound during the running

If there is abnormal working sound during the running, stop the engine right away. 
If you continue to run the engine, it will result in serious damage accidents.

Check all the bolts and nuts if loosened or not. Find out the reason of the fault and 
eliminate the trouble.      

3. Avoid running the engine in the resonance range

Due to the intrinsic structure factor, the working machinery may resonate this 
product in certain rotary speed range. It will make the vibration of the engine 
become very incredible. So avoid running the engine near this rotary speed. If 
continue to run the engine at this case, it will result in serious damage accidents.

4. A.  Add the cooling water to the cooling water tank

Inspect the cooling water whether is enough or not during the running. And 
supply the cooling water to the water tank in time.

B.  Check the amount of the cooling water at the export hole whether reduced 

or not.

If the exported cooling water decreases, stop to check the engine.

C.  Check the cooled water whether injected or leaked?

If there is an abnormal case, stop to check the engine right away.

If continue to run the engine lacking of the cooled water, it will cause the 
engine over hot to burn out the inside parts.

5. Check the oil pressure lamp whether is on and the oil pressure sign is red

If the oil pressure sign is red, stop to check the engine.

If continue to run the engine at the no-oil state it will result in burning out the inside 
parts.

6. Check the charging indication lamp is on.

If the charging indication lamp is on, it indicates that you can't charge the battery.

7. If there is burn or funk or smoke, please add the lubricating oil in time. You must 
stop the engine when add the lubricating oil. If there is an abnormal case, but you 
can't determine the reason, stop the engine and send to the dealer's shop to
