Never disconnect a hydraulic hose or tube containing
pressure. Pressures in this hydraulic system are high enough
to cause serious injury or death. Hoses may whip or hydraulic oil may burn skin, or cause eye damage.
Use extreme caution when working with the hydraulic system.
There are some procedures in this section that will require the
chassis engine to be running. In these instances, the operational
status will be indicated. Otherwise, make sure that the chassis engine is shut o and the keys are re-
moved. Movement of the unit’s parts can cause serious injury or death. Keep clear of tailgate area.
REPLACING PACK PANEL GUIDE BLOCKS
It is essential that the guide blocks be replaced before any portion of the swing/ pack panel assem-
bly comes into contact with the tailgate itself. The swing panel may come into contact with tailgate
from either the top or bottom surfaces of the guide blocks.
1) Park the unit on a level surface with the tailgate shut. Bring the swing and sweep panels to
the retracted position. Remove the keys from the ignition, use proper lock-out/ tag-out
procedures, and chock the tires. Finally, disconnect the negative battery cable.
2) Remove the tailgate light bar assembly.
3) Reduce the hydraulic pressure in the system by operating the hydraulic valve on the tailgate
until all the hoses are limp.
4) Next, disconnect and CAP/ PLUG the packing cylinders and hoses at the pack panel.
5) With a suitable lifting device, lift the complete pack panel assembly. The pack panels will
rotate until the guide blocks become exposed.
6) Once the pack panel assembly is raised, the guide blocks may be inspected or replaced.
7) For installation, simply perform the above procedures in reverse order.
