在工作温度下，液压油温度很高且处于压力下。 热机油能造成烫伤。 为避免可能的人身伤害，在断开或拆下任何液压管路或部件之前，请释放作业机具液压回路（动臂、斗杆、铲斗和回转机构）、行驶回路及液压油箱加注口盖处的压力。 仅当发动机停止并且加注口盖冷却到可以接触时方可拆下加注口盖。 |

在检验、保养、测试、调整及维修产品时，必须小心以确保收集好排放出的油液。 在打开任何舱室或拆卸任何储有液体的部件之前，要准备好合适的容器收集液体。 将所有液体收集进合适的容器之后，按照本地法规和指令处置所有液体。 |
- 调整供应至旋转回路的液压压力。 有关正确的步骤，请参阅主机维修手册。 将压力调整至大约
14000 kPa (2030 psi) 。Show/hide table

(R) 向右旋转转子。
(L) 向左旋转转子。 - 将工具 (A) 安装到测试接头 (1)。
- 将工具 (A) 安装到测试接头 (2)。
- 起动主机发动机。 操作主机，直至液压油达到正常工作温度。
- 锁定液压剪，以防止液压剪旋转。
- 尝试向左旋转作业机具。 记录两个压力表上的读数。
- 记录这两个压力表之间的压差。 此压差应为
14000 ± 1000 kPa (2030 ± 145 psi) 。 如果压力符合技术规格，则交叉安全阀工作正常。 如果压力不符合技术规格，请参阅故障排除部分。 - 重复步骤 6 和 7，以便向左旋转。
