滚热的油或液压油的压力会对人员造成伤害。 发动机停机之后，液压油的压力仍会保留在液压系统里。 对液压系统进行维修之前，如果不事先释放压力，可能会造成严重伤害。 卸下液压系统的部件或管路时，确保所有的作业机具都已降到地面上，而且液压油温度已冷。 只能在发动机停机，并且加注口盖冷却到可以用徒手触摸时才能卸下加注口盖。 |
- 请参阅操作和保养手册, "系统压力释放"。
- 将工具 (A) 安装到液压油箱上。 将一条供气软管连接到工具 (A) 上。 施加 276 至 414 kPa (40 至 60 psi) 的气压。 这将使液压系统抽吸出真空。
- 将电源断路开关 (1) 转到断开位置。
- 断开线束组件 (2) 和软管组件 (3) 。
