双机油滤清器系统使您能够在发动机运转时更换机油滤清器滤芯。
正常运转期间，控制阀应处于"主工作(Main Run)"位置。 控制阀在此位置时，机油经主机油滤清器壳体 (5) 中的这机油滤清器滤芯 (1) 过滤，过滤后的机油将单向阀 (3) 右移。 这将关闭副机油滤清器壳体内的油道。 控制阀在此位置时，在机油压力被释放，副机油滤清器壳体被排干机油之后，即可更换副机油滤清器滤芯 (4) 。
当控制阀杆 (8) 被拉出至"副工作(Auxiliary Run)"位置时，机油将由副机油滤清器滤芯 (4) 过滤。 过滤后的机油此时将单向阀 (3) 左移。 这将关闭主机油滤清器壳体内的油道。 控制阀在此位置时，在机油压力被释放，主机油滤清器壳体被排干机油之后，即可更换主机油滤清器滤芯 (1) 。
无论哪一个机油滤清器壳体内的机油滤清器滤芯被更换之后，机油滤清器壳体必须注满油，以便在将油流从一个机油滤清器壳体导向另一个机油滤清器壳体时保持机油压力不变。
为向任一机油滤清器壳体注油，打开注油阀 (11) 至少达5分钟。 这将引导机油经小管向空机油滤清器壳体注油。
