Manual Extract: Minimum flow adjustment

Loosen the hexagon nut (808) and tighten (or loosen) the hexagon socket head locking screw (953) to adjust the flow control characteristic. Similar to the maximum flow adjustment, this does not change other control characteristic. However, if the hexagon socket head locking screw is tightened too much, the required power may increase at the time of maximum discharge pressure (during relief), so adjust this carefully.
