1、剛啟動就猛轟油門
裝載機發(fā)動機剛啟動時，機身溫度低、機油黏度大、流動性差，機油在短時間內不能暢流至各潤滑點。如果此時猛轟油門，會導致發(fā)動機轉速瞬時升高，各運動副潤滑不良，運行阻力也會增大，如果猛轟油門，活塞、連桿、曲軸會產生劇烈撞擊，加速機件的損壞。
When the loader engine just started, low body temperature, oil viscosity, poor mobility, not the smooth flow of oil in a short time to the lubrication points. If at this time Meng throttle will result in increased engine speed transient adverse movements deputy lubrication, running resistance will increase, if Meng throttle, piston, connecting rod, crankshaft will have a dramatic impact,accelerating mechanical damage.

2、啟動后不經曖機運轉而直接作業(yè)
由于機身溫度低，機油黏度大，會使機油泵供油不足，導致短時間內運動副得不到良好的潤滑，磨損加劇。大負荷時，甚至會發(fā)生拉缸、抱瓦等事故。在冬季，液壓軟管脆性大，直接作業(yè)易迸裂，會使液壓油大量外泄。
As the body temperature is low, oil viscosity, will pump oil supply shortage, resulting in a short time deputy campaign not good lubrication, wear and tear. When a large load, or even pull the cylinder, hold tile and other accidents will happen. In winter, the hydraulic hoses brittle, easily burst direct jobs, will make a lot of hydraulic fluid leakage.

3、作業(yè)過程中直接補充冷卻水
冷卻水不足，將導致柴油機缺水過熱。柴油機高溫狀態(tài)下直接補充冷卻水，整個冷卻系統(tǒng)瞬間會產生大的溫差，使缸蓋、缸套、缸體等瞬間脆裂，產生微裂紋，逐漸滲漏冷卻水，以致漏油、漏氣。
Insufficient cooling water will cause the diesel shortage overheating. Diesel directly under high temperature cooling water added, the entire cooling system instantly generates a large temperature difference, so that the cylinder head, cylinder liner, cylinder and other instant rattle, microcracks, gradually leaking cooling water, resulting in oil spills, leaks.

4、長時間怠速運轉
特別在冬季野外作業(yè)，天氣寒冷，不易啟動，不少駕駛員習慣于裝載機不作業(yè)時讓其長時間怠速運轉。長時間怠速運轉機油泵會出現泵油不足，機油壓力低，各運動副需求潤滑的油量和油壓達不到要求，摩擦阻力增大，磨損加劇，特別是活塞、缸套磨損大，易造成竄氣；有時還會導致氣門和活塞環(huán)卡死。此外，長時間怠速運轉柴油霧化不良，燃燒不完全，會造成滯燃期延長，積炭嚴重，工作粗暴。
Special field operations in the winter, cold weather, easy to start, many drivers do not work when used loaders allowed prolonged idling. Prolonged idling pump will pump oil shortfalls, low oil pressure, fuel and lubricating oil pressure needs of each deputy campaign mainly the friction increases, increased wear, especially in the piston, cylinder liner wear, easy cause channeling gas;sometimes lead to valve and piston rings stuck. In addition, prolonged idling diesel poor atomization, incomplete combustion, ignition delay will cause prolonged, severe coke, work rude.

5、啟動困難時引火曖機
裝載機不易啟動時，有的駕駛員使用明火置于進氣口或進氣支管與氣泵氣管接口處，啟動柴油機，強制助燃柴油機。這種作法不僅會使空濾燒損，而且會導致點火不正時，柴油機提前或滯后暴燃，工作粗暴，缸套、活塞、連桿等受力部件受到劇烈沖擊，受力不均，損壞機件。因此，嚴禁啟動困難時引火著車。
When the loader is not easy to start, and some drivers to use an open flame into the air intake or intake manifold and pump pipe interface, start the engine, forced combustion diesel engines. This approach will not only burn the air filter, and will lead to errors when the ignition, diesel advance or lag deflagration, work rude, cylinder, piston, connecting rod and other parts subject to severe impact force, uneven force, damaged machine pieces. Therefore, non-pyrophoric difficult to start the car.

6、帶負荷停機或作業(yè)后立即停機
裝載機帶負荷停機或作業(yè)后立即停機，冷卻系統(tǒng)隨即停止工作，散熱能力急劇下降。工作產生的大量熱量積聚在熱源附近不能及時散發(fā)，使氣缸蓋、缸套、缸體等受熱部件的冷卻水沸騰，機件過熱，高溫燒蝕。同時還會使附著其表面的機油變質，造成下次啟動困難。
Loaders with load after downtime or job immediately shut down, the cooling system immediately stops working, a sharp decline in cooling capacity. Work generated a lot of heat build-up in the vicinity of the heat source can not be distributed, so that the cylinder head cooling water cylinder, cylinder and other parts of the boiling heat, mechanical overheating, high-temperature ablation. While also so attached to its surface oil deterioration, causing difficulty in starting the next.
