裝載機液壓缸內漏，油路進了空氣，轉向系統壓力過低，導致泛起裝載機轉向沉重故障。管路連接錯誤或者是管路有梗阻，都會導致裝載機轉向沉重故障現象。

裝載機先導壓力值的調整方法是先用專業的拆卸工具松開溢流閥鎖緊螺母，然后假如是先導壓力值偏小，就向順時針方法調大先導壓力值，假如是壓力值偏小，就向逆時針方法調小，調整先導壓力值后，裝載機轉向沉重故障排除。
Loader pilot pressure value adjustment method is to first use a professional removal tool loosen the locknut relief, and then if the pilot pressure value is too small, the pilot would turn up the pressure value in the clockwise method, if it is too small pressure on transfer of small counterclockwise method, adjusted pilot pressure value, loaders steering heavy troubleshooting.

停機熄火用壓力表檢查裝載機先導壓力值，正常的先導壓力值應該是發念頭怠速的時候不低于2.2MPA,發念頭高速的時候要不高于5MPA,假如檢查裝載機壓力值不為劃定的值,那么導致裝載機轉向沉重故障現象泛起的原因就是先到壓力值分歧錯誤，就要調整。
Stop stalling when the pilot pressure with a pressure gauge to check the value of the loader, the normal pilot pressure value should be no less than the engine idling 2.2MPA, or when the engine speed is higher than 5MPA, check if the value is not zoned pressure loaders given value, resulting in heavy steering loaders Symptom thrown reason is first pressure difference error, we must adjust.
