Free Swing, All Model
1) Free swing allows the upperstructure to “coast” to a stop.
2) The swing brake does not apply while free swing is on.
Note: The controller needs a RPM signal for free swing.
When the free swing switch is pressed the controller sends 24v to energize the free swing
solenoid. The valve shift and connects both sides of the swing motor together through an
orifice. This allow for “smooth” starts and stops. The upperstructure “coasts” to a stop.
