Due to the bad condition and the extension work time, the capability of the engine 
will become worsen. Such as: increase the consumption of the fuel and oil, and 
increase the harmful matter of the exhaust, increase the vibration and noise, and 
then shorten the life of the engine. Reinforce the maintenance, daily and terminal 
inspection, you can keep the unit's efficiency and prevent the fault.

5.1Check

Daily check and terminal check

Daily check: You should do the daily check before starting the engine every day, 

the details have been mentioned in first section of chapter 4, and you should 
perform it as a regulation.

Terminal check: Advise you make a running diary, note every day's running and 

checking result, add up the unit's work time, make terminal check and 
maintenance according to this manual.
Terminal check include: 50h 250h

500h

1000h

2000h(h for hour)

5.2Items for terminal check

The following list include items and time interval of the terminal check. According 
to the engine's use, load condition, fuel and lubricant's quality, and other condition, 
the time interval of the terminal check can ahead or delay.

Maintenance

The abrasion of the intake and exhaust sealed belt

Idle speed adjusting

Clean and Replace the element of the air cleaner

Check the warning system

Check the electrolyte level and charge for battery

Check items

Check the fuel leakage

Drain water in the fuel tank

Check the oil level and add

Check the leakage

Replace the lubricant

Replace the filter element

Clean the radiator's element

Replace the cooling water

Operate the speed regulator

Check and supply the fuel tank level

Replace the diesel filter element

Check and add the cooling water

Wash and maintain the cooling system

Replace the fuel and cooling water pipe

Rubber pipe

Air intake system

Lubricant

Cooling 

water

Electrical

cover

Injector and

 injection 

pump

Check and adjust for injector pressure

Check and adjust for injector timing

5.3 Procedure for terminal check

5.3.1 The first 50 running hours: because the engine just start running, the inside 
running parts abration each other, the lubricant will be polluted soon. You should 
replace the lubricant and oil filter element. It is easier and quicker to drain the 
lubricant, when the engine is still hot.
