1、在極端條件下檢測裝載機風扇轉(zhuǎn)速的系統(tǒng)實際工作壓力，以確定該回路的液壓件是否有故障、油溫傳感器或控制電路的工作是否正常。此時風扇轉(zhuǎn)速和系統(tǒng)工作壓力均應為最大值，否則，應對系統(tǒng)相應參數(shù)進行調(diào)整或更換受損元件。
Shandong loaders fan speed detection system actually working pressure under extreme conditions, to determine the hydraulic circuit is faulty, if oil temperature sensor or control circuit is normal. In this case the fan speed and system pressure should be the maximum, otherwise the corresponding parameters can be adjusted to deal with the system or replace damaged components.

2、裝載機液壓油散熱器是否有污物堵塞，導致散熱效率下降，必要時清洗散熱器。
Shandong loader hydraulic oil cooler if there is dirt clogging, resulting in decreased cooling efficiency, clean the radiator if necessary.

3、裝載機系統(tǒng)中相關液壓參數(shù)的檢查。
Check the hydraulic parameters of Shandong loader system related.
