Swing Lock, All Models
1) When the swing brake switch is pressed the swing brake will apply.
2) The swing control will be locked in neutral.
When the swing brake switch is pressed the controller sends 24v to the swing brake
solenoid, which shifts and allows the swing brake to apply. The controller also sends 24v to
the swing shutoff solenoid. This sends pilot pressure through the swing shuttle valve to both
ends of the swing control spool in the control valve. This hydraulically locks the control spool
in neutral.
