Return change valve for direct return flow
The change valve has two settings.
When "direct return flow" is enabled, the return flow is directed from
the implement to the hydraulic oil tank via the return filter. The return
flow is directed via the right auxiliary port 1 connector at the arm on-
ly.
When "indirect return flow" is enabled, the return flow is directed
from the implement to the return filter via the control valve and then
to the hydraulic oil tank. In that case, the return flow may use the left
or right auxiliary port 1 connector of the arm (depending on the po-
sition of the rocker switch for auxiliary port 1).
Move the return change valve to the required position as shown in the figure, depending on the action of the im-
plement being used (rotary or breaking).
