B Lowering
4. When the position control lever is moved to the
Lowering position, the control arm (2) rotates to the
arrow. Therefore, the spool drive lever (1) moves
around the fulcrum P and push the spool (3) and
poppet 2 (4) opening the Lowering circuit.
5. When the lift arm moves downward, the feedback
arm (5) is rotated to the arrow, since the feedback
rod (6) is actuated. Therefore, the spool drive lever
(1) moves around the fulcrum Q and pull the spool
(3).
6. The lift arm stops when the spool (3) returns to the
neutral position.
