MANUAL RELEASE CIRCUIT (UP MODE)
(1) With the manual release valve K open, the engine can also be raised manually to the fully tilted position.
(2) Oil from the upper chamber of the tilt cylinder will flow through valve K into the lower chamber of the
cylinder.
(3) The upward movement of the piston rod will increase the cylinder area beneath it, thereby allowing oil
from the reservoir to flow into this area.
