1. After the engine is started for the first time, heat engine operation is performed for 5 minutes. Keep the load running at a low speed before the engine is hot, and do not operate at full load or at low speed and no load. 2, to avoid overloading operation. The engine cannot run at full load during the running-in period. It can be run at a speed of 3000 rpm and a load of about 50%. 3. Change the oil on time. After the engine is running for 20 hours, the heat engine will change the oil, otherwise it will not be able to drain the residual oil in the body. After changing the oil for 20 hours, change the oil every 100 hours. 5, the choice of oil. It is very important to choose the right oil. If the used oil grade is not suitable, it will cause the piston ring to stick and burn the piston ring; the rapid wear of the cylinder sleeve; the rapid wear of the bearing and other moving parts will shorten the life of the diesel engine. 6, keep the air filter cleaner. If there is a lack of engine power and the smoke color deteriorates, replace the air filter or purge the core. The first cleaning of the filter element is to use 100 hours, the second time is to use 500 hours, and the filter element is replaced after 1000 hours. 7, common troubleshooting (1) It is not possible to make a car - check whether there is oil in the fuel tank, whether the fuel is clean, check whether the fuel tank switch is on, and check whether the fuel injector is fueled. (2) It is difficult to start - whether the pressure relief handle is opened; whether the engine oil is marked according to the refueling; whether the crankshaft bearing is worn badly; whether the cylinder sleeve is "pulled". (3) Insufficient engine power—Incorrect intake during oil supply; incorrect valve clearance; failure to reach standard compression ratio; insufficient air intake.

4. If the fuel mixes with water and dirt, it can cause the diesel engine to run abnormally or cannot be used as a vehicle. If there is water and dirt in the fuel, the fuel should be stored in a clean container and allowed to settle for more than 2 hours. Then use a hose or pump to pump the fuel out. The oil at the bottom of the container should not be used.
