2.4 OPERATIONS – PVG VALVES MANUAL OPERATION
The levers on the PVG Valves can be used to manually operate the ROTO 180 system from
outside the truck. These levers operate the hoist, the rotation of the dump body and the
tailgate, see Figure 2.4.

WARNING
Manual operation of the PVG Valves bypasses many of the safety features associated
with this system thus should be only used as a backup operation method.
NOTE
The following subsections assume the operator has completed all steps found in Section
2.2.2 to enable the ROTO 180 system.
2.4.1 Raising Body – Manual Operation
NOTE
Operation of the ROTO 180 system with the body turned away from the center position
requires the use of either manual or hydraulic Raildogs to stabilize the truck. For
operation of Raildogs, refer to the separate “Raildog” manual.
