The boom section valve assembly includes the right,
center and left boom section valves, a bypass valve for
each of the boom section valves and the boom section
bypass shut−off valve.
IMPORTANT: Each valve actuator has an internal
circuit breaker to protect the actuator motor. The
circuit breaker should reset in 20 seconds after
power to the actuator is removed.

1. Remove the boom section valve assembly from ma-
chine (see Spray Control Manifold Assembly in this
