Welcome to inquire! Contact: Mr. seats. Excavators now constantly evolving market which, so if they go into winter Wuxi sale of second-hand 120 excavator, in cold weather, the test device will be more severe than usual. So when winter construction, maintenance excavator what errors do exist a wrong practice: the serious consequences of early or hold cooling water drainage can cause: the engine block or sudden shrinkage cracks Splitting; former flame to idling, be? Cooling water temperature drops below 60 degrees ℃, the water is not hot hand Kunshan 120 excavator market, and then turn off the water. If prematurely let go of the cooling water, the body suddenly at higher temperatures generated by the sudden invasion of cold air will shrink, crack. The body should drain the remaining water completely drained to prevent freezing its expansion, so that the body bursting. Error approach II: start with an open flame combustion can lead to serious consequences: the weight is burning machines, ranging from damage to the engine; you can not remove the air filter 120 second-hand excavator sales in Nanjing, with cotton dipped in diesel fuel ignited firelighters made home to start the trachea into the implementation of combustion. Thus during the boot process, the outside air is not filtered dust and inhaled directly into the cylinder, causing abnormal wear of pistons, cylinders and other parts, will result in diesel crude, damage the machine. When using hand digging machine need to pay attention to what common sense, we not only want them to work when using the excavator and should know how to take good care of our machines. During the first use, and after the first start until hydraulic excavators up to the high speed when it can go to the use of second-hand excavator 120 excavator, so the impact is not easily damaged if pressed lights or excavator filter warning lights so this phenomenon caused by two hydraulic excessive happen if this happens it is imperative to reduce the speed until the oil pressure warning light and return to normal use, install oil pressure gauge when we need to work only when the engine can be installed or uninstalled when using oil pressure gauge oil pressure must be put to the exact location of the measurement value, when the temperature is different for each region must be measured to the engine operation when it can go to the oil pressure measured temperature.
