Once the 12P93 hose length is adjusted, install between the C.V.S. hydraulic valve and
the hydraulic tank fittings (See drawing 90H88), and tighten.
12.
Remove the 90 degree hydraulic fitting [Part No. 11P06] that connects from the upper
bulkhead fitting inside the mainframe to the 12P03 hydraulic hose that runs to the jib
lockout valve (See drawing 90H55 & 90H88 – Note 3).
13.
Replace with hydraulic fittings [Part No. 12P69 & 13P04] and relief valve assembly [Part
No. 21P93] and tighten (See drawing 90H88).
14.
Refill hydraulic tank to proper fluid level.
15.
Verify that the C.V.S. is operating properly. Start the truck, engage the P.T.O., and then
retract the jib cylinder full stroke. Next, while extending the jib cylinder back out have
someone push or rotate the C.V.S. lever arm forward (toward the back of the truck
cab). The C.V.S. is operating properly when the jib cylinder stops extending by
rotating the C.V.S. lever arm forward.
16.
Containers to be used in conjunction with the C.V.S. need modified by adding a stop tab
to the side of the container longsill (See drawing S-878). Dimensions given are a
recommendation only. When modifying containers for use with the C.V.S. it is the
primary responsibility of the installer to verify that adequate rear end overhang and
full latch plate engagement into body locks exists for each container.
