1、定期更換機油及濾芯。任何質量等級的潤滑油在使用過程中油質都會發生變化，為了避免濟南裝載機故障的發生，應結合使用條件定期換油，并使油量適中。
Occurrence of any quality grade of oil in the course of CNPC quality will change, in order to avoid the occurrence of a fault in Jinan loaders, should be combined with a regular oil change conditions of use, and to moderate oil.
2、保持曲軸箱通風良好。現在大部分汽油機都裝有PCV閥，但竄氣中的污染物會沉積在PCV閥的周圍，可能使閥堵塞。因此，須定期清除PCV閥周圍的污染物。
Now most of the gasoline engine are equipped with PCV valve, but channeling gas contaminants are deposited around the PCV valve, the valve may be clogged. Therefore, subject to periodic removal of pollutants around the PCV valve.
3、定期清洗曲軸箱。小鏟車發動機在運轉過程中，燃燒室內的高壓未燃燒氣體、酸、水分、硫和氮的氧化物經過活塞環與缸壁之間的間隙進入曲軸箱中，與零件磨損產生的金屬粉末混在一起，形成油泥。因此，應定期清洗曲軸箱，保持發動機內部的清潔。
Small forklift engine operation, the pressure in the combustion chamber is not gas, acid, water, oxides of sulfur and nitrogen combustion through the gap between the piston ring and cylinder wall into the crankcase, the wear of parts produced with the metal powder mixed in together to form sludge. Therefore, the crankcase should be cleaned regularly to keep the engine clean inside.
4、定期清洗燃油系統，控制積炭的生成，能夠使發動機保持最佳狀態。發動機水箱生銹、結垢是最常見的問題。銹跡和水垢會限制冷卻液的冷卻系統中的流動，降低散熱作用，導致發動機過熱，甚至造成發動機損壞。所以要定期清洗水箱，除去其中的銹跡和水垢。
Engine tanks rust, scaling is the most common problem. Rust and scale limit of the coolant flowing in the cooling system, reduces cooling effect, resulting in engine overheating, and even cause engine damage. Therefore, the tank should be cleaned regularly to remove rust and scale them.
5、保養三濾：三濾是指空氣濾清器、機油濾清器及汽油濾清器。三濾在汽車發動機上對空氣、機油和汽油起著過濾作用，從而對發動機起到保護作用，同時也提高了發動機的工作效率。
Three filter is the air filter, oil filter and fuel filter. Three filter in the car engine for air, oil and gasoline plays a filtering effect, which play a protective effect on the engine, but also improve the efficiency of the engine.
