液压油箱中的机油流至变矩器、停车制动器释放泵和制动器冷却齿轮泵。 机油通过停车制动器释放泵段输送到停车制动器释放油滤清器 (1) 中。
然后流经进口通道 (7) ， 机油将注入壳体内部 (9) 与滤芯 (8) 之间的空间。 机器正常工作期间，机油流经滤芯 (8) ，然后从出口通道 (5) 流至液压系统的其他部件。 滤芯 (8) 会过滤掉机油中的任何碎屑。
如果滤清器滤芯 (8) 充满碎屑，则会限制油流，从而导致滤清器内部压力增高。 压力油则会使旁通阀 (3) 克服弹簧 (4) 阻力而移动。 此外，旁通开关 (2) 将启用，驾驶室中也将显示报警信号。
然后，机油经过开启的旁通阀，流至液压系统的其他部件。 如果机油没有流经滤清器滤芯，机油中的碎屑将对液压系统中的其他部件造成损坏。
需要采用使用正确的维护方式，确保滤芯 (8) 没有塞满碎屑。 如果滤芯 (8) 塞满碎屑，则无法向液压系统输送清洁的机油。
