1. 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.

2. When the lift arm moves downward, the feedback

lever shaft (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).

3. The lift arm stops when the spool (3) returns to the

neutral position.
