Work Tool Flow Control - If Equipped
辅助管路能提供单向流量或双向流量。
单向流量用于机具，如液压锤。 双向流量用于如螺旋钻之类的作业机具。
在改变液压辅助回路的流量模式前，确保符合下列标准：
- 将机器停放在水平地面上。
- 所有作业机具和所有选装部件降到地面上。
- 停车制动器已接合
- 液压力已释放
- 回转锁销已安装。
- 发动机停机

确保机器和所有作业机具在推荐的维修位置。 安装回转锁销并关闭发动机。 在移动球阀手动杆前，确保所有人员远离作业机具。 改变阀的位置可能引起作业机具的意外运动。 能导致严重的人员伤亡。 |

使用阀杆转动阀。 确保已完全转动球阀，直至球阀停止为止。
为使阀从双向流量转到单向流量，顺时针转动阀。
为使阀从双向流量转到单向流量，逆时针转动阀。

将阀转入上图示位置，以进行下述功能：
- 可伸长斗杆作业
- 需要单向流量的作业机具
将阀转动90度，以使用所需的双向流量作业机具。
注: 在将阀转到双向流量之前，必须销住可伸长斗杆。
