Standard Two-Circuit Hydraulic Plumbing
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.
Push-off Cylinder Hydraulic System
A pressure relief valve, in both two-circuit and three-circuit hydraulic plumbing, pro-
tects the pushoff cylinder hydraulic system. This pressure relief valve is designed to
limit the hydraulic oil pressure delivered to the push-off cylinder. This valve is preset
from the factory at 2000 psi.
*To adjust the pressure relief valve, see Troubleshooting section.
