4.2.2 When the engine is running normally, inspect the engine oil pressure and 

temperature, cooling water temperature and the working condition of the charging 

indicator frequently 

Be careful to observe the color of exhaust gas and listen to the working sound 

during the operation. 

4.2.3 In the normal run course, shouldn't increase or decrease the rotary speed 

and load suddenly.

WARNING

If you find one of the phenomena that the engine oil pressure is over low and 

the temperature of cooling water is over high (It's over the specified range in 

the chart 2.4); dense smoke exhausting from the engine; and there is knock 

sound in the normal run course, stop the engine as soon as possible and 

check the reason of these symptoms. Otherwise, the fault will lead to 

damage of the engine.

4.2.4 Provide the adequate heat preservation measure for running the engine in 

the winter to prevent the temperature of the cooling water and engine oil is over 

low. However, Provide the adequate cooling measure for running the engine in the 

summer to prevent the temperature of the cooled water and engine oil is over high. 

WARNING

Never keep the engine running under overload for long time. Otherwise it will 

result in fault and shortening the service life.

(1) Replace the engine oil, and clean the lubricating oil filter element

Replace the engine oil every 100 hours.

Clean or replace the lubricating oil filter element. (Refer to figure 7-1)
