Lifting
1. When the position control lever is moved to the LIFT
position, the control arm (2) rotates to the arrow.
Therefore, the spool drive lever (1) moves around
the fulcrum P and pull the spool (3) opening the LIFT
circuit.
2. When the lift arm moves upward, the feedback lever
shaft (4) is rotated to the arrow, since the feedback
rod (5) is actuated. Therefore, the spool drive lever
(1) moves around the fulcrum Q and pushes the
spool (3).
3. The lift arm stops when the spool returns to the
neutral position.
