Hydraulic System 259
Figure 5-4
Directional control valve
• Tailgate: 4 ways, 3 positions - air-actuator operated or electrically operated (optional)
• Packer: 4 ways, 3 positions - air-actuator operated or electrically operated (optional)
• Body hoist: 3 ways, 3 positions - air-actuator operated or electrically operated (optional)
• Crusher panel (optional): 4 ways, 3 positions - manually operated
NOTE: The directional control valve may have up to 5 sections depending on whether or not the unit
is equipped with a crusher panel and/or a glass compartment. For example, if the unit is
equipped with a crusher panel but no automated arm, a fourth section would be added to the
valve stack to allow operation of that crusher panel. This section would be located next to the
tailgate section.
For more information on the directional control valve, see Hydraulic Schematics on page 305. To
learn how to adjust hydraulic pressure, see Hydraulic Pressures on page 288.
