The apron cylinders and the push-off cylinder are controlled on the same circuit with
the sequence of the operation controlled by a sequence valve. The other hydraulic
circuit controls the lift cylinders on the earthmover.
*To adjust the sequence valve, see Troubleshooting section.
Optional Three-Circuit Hydraulic Plumbing
The apron cylinders, push-off cylinder, and lift cylinders are all on separate hydraulic
circuits.
CAUTION! Relieve all hydraulic pressure before working on the hydraulic
system.
