SWING SYSTEM RT770E
armrest lockout manifold. With the Swing Brake Selector
Switch positioned to ON, the Swing Brake Release Valve
blocks the regulated flow to the brake release port and spring
pressure in the swing brake applies the brake. When the
Swing Brake Selector Switch is positioned to OFF, the
regulated flow is directed from the pressure reducing/
sequence valve to the brake release port, overcoming the
brake spring pressure and releasing the swing brake.
Regulated flow from the pressure reducing/sequence valve
is also provided to the power brake valve where it is available
for the activation of the swing brake when the pedal is
depressed.
