------ WARNING! ------

将机器放在光滑、水平的表面上。

将作业机具降到地面。接合停车制动器后,再启用机器的机具液压维修模式。

其他人员应远离机器。清理机具连杆下方和周围的区域。

如果机器处于机具液压维修模式并且作业机具升离地面,不要将操纵杆置于浮动位置。将操纵杆置于浮动位置将使作业机具连杆立即落下。

作业机具连杆落下可导致人身伤亡。


机具液压维修模式用于特定的测试和调整步骤。 在此模式下只有提升和倾斜回路的基本功能可以工作。

注: 在此维修模式下所有高级机具控制特性将禁用。 将禁用的机具控制特性有限位、油缸刹车和卸载速度控制。 但是,浮动控制将保持启用。 如果提升操纵杆置于浮动位置且机具液压维修模式激活,则提升连杆会立即降下。
