1. The foot: namely oil to the full, full, air water enough. Diesel, gasoline and air supply or not interrupt, can appear starting difficulties, burning is bad, the power decrease, the engine will not operate properly wait for a phenomenon. If the oil supply or interrupt can make the engine bad lubrication, the body badly worn appears even the tile burning phenomenon. If the cooling water shortage will make machine high temperature, power decrease, the wear is intensified, reduce the using life.

2. Grinding: namely bond. This is to extend the service life of foundation, whether new car or the engine after overhaul, must according to rules team, can put into normal operation.

3. Adjustment: namely diesel engine or the gasoline engine valve clearance, with gas phase, injection advance Angle, oil injection pressure and ignition timing etc should be timely check and adjustment, to ensure that the engine often are in good technical status, can save fuel and prolong service life.

4. Use: that is correct use of the engine. Before moving, should make the bearings and lubrication part get lubrication. After starting for up to 40 ℃ temperature should be-50 ℃ again when put into operation? It is strictly prohibited to long time overload or low speed homework. Before the downtime, should first uninstalled load reduce speed? The winter after parking for water temperature should be down to 40 ℃-50 ℃, put net cooling water has note fandangle except the engine of the list. Usually to do the maintenance work regular engine, to make the machine always keep in good condition operation. Frequently observed, frequently check, find fault, promptly eliminate.

 
5. Inspection: that is often checking fastening parts. For diesel and gasoline engine use process affected by the impact and load distributed influence, bolts, nuts easy to loose. And of each place adjustment bolts to check, so as to avoid the damage of the body for loose and accident.
