作业机具系统是配有负载感应阀的中位关闭系统。 系统采用电控方式，并具有先导油辅助。 机器的每组油缸都有独立的系统。
如果机器配备可选的裂土器，则缸盖回路的管路安全阀 (6) 是裂土器控制阀 (5) 的组成部分。 主安全阀 (10) 安装在提升控制阀 (2) 内，从而保持作业机具系统的液压压力. 所有回路的保护使用主安全阀。
全部控制阀都包含负载止回阀。 全部控制阀都包含补偿阀。 裂土器回路配有单个补偿阀，该补偿阀位于杆端回路。 管路安全阀 (6) 具有缸盖回路补偿阀的功能。 其他控制阀具有两个补偿阀。
当控制装置处于保持位置时，阀的控制滑阀阻止机油进出油缸。 控制阀的中位弹簧使滑阀处于 保持位置。
