Operational Checks
运转检查有助于诊断传动系性能不佳的问题。
注: 进行任何运转检查之前，核实所有油液都处在正常的高度。
- 将变速箱换档杆挂入非空档 (NEUTRAL)的一个档位。 试着起动发动机。 发动机应无法起动。
- 将变速箱换档杆挂入空档 (NEUTRAL)位置。 起动前发动机。 起动后发动机（如有配备）。 在所有前进 (FORWARD)档位上运转机器。 在所有倒退 (REVERSE)档位上运转机器。
- 当牵引机的两个车轮以相同转速转动时，踩下差速器锁踏板。
- 当机器以任何档位行驶的同时，接合变速箱保持控制。 在取消变速箱保持控制之前应维持当前的变速箱档位。
- 如果机器有后发动机，核实前变速箱和后变速箱保持同步。 起动牵引机发动机。 起动铲运机发动机。 确保施加驻车制动器。 走到机器后部。 核实变速箱同步指示灯不亮。 如果变速箱同步指示灯亮，说明变速箱没有保持同步。
- 当机器行驶的同时，接合减速器。 机器速度应降低。
如果上述任何的机器操作异常起效，请参阅本系统操作、测试和调整, "传动系故障诊断"。
