LOWERING
â–¶
When setting the control lever to the Lowering position, pressure applied to the spool is released so the spool
is returned to its original position by the spring. Therefore, oil in the cylinder is returned back to the tank, the
lift arm is lowered, and the spool is returned to the neutral position by the feedback rod.
