1、在极端条件下检测装载机风扇转速的系统实际工作压力，以确定该回路的液压件是否有故障、油温传感器或控制电路的工作是否正常。此时风扇转速和系统工作压力均应为最大值，否则，应对系统相应参数进行调整或更换受损元件。
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、装载机液压油散热器是否有污物堵塞，导致散热效率下降，必要时清洗散热器。
Shandong loader hydraulic oil cooler if there is dirt clogging, resulting in decreased cooling efficiency, clean the radiator if necessary.

3、装载机系统中相关液压参数的检查。
Check the hydraulic parameters of Shandong loader system related.
