2. Lower drill into field position and completely retract
box lift cylinder at middle of tongue. Loosen base
end hose JIC fitting on left transport lift cylinder and
base end JIC fitting on box lift cylinder
.
3. Slowly supply oil to base end of transport lift cylin-
ders until oil appears at loosened hose fitting. Oil
may not appear at both locations at the same time.
As oil begins to appear at a fitting, tighten that fitting
and proceed until both fittings have been tightened.
4. Completely extend transport lift cylinders and imme-
diately lock cylinders up by flipping up cylinder lock
channels on both transport lift cylinders and box lift
cylinder.
The hydraulics could fail, causing the openers to fall and
crush you. To prevent serious injury or death, always secure
cylinder lock channels over extended transport-lift cylinders
before working under openers.
5. When cylinder lock channels are in place, loosen rod
end hose fitting on left transport lift cylinder and rod
end hose fitting on box lift cylinder
.
6. Slowly supply oil to rod end of transport lift cylinders
until oil appears at the loosened hose fittings. As oil
begins to appear at fitting, tighten that fitting and pro-
ceed until all fittings are tightened.
7. Extend transport lift cylinders, and remove the cylin-
der lock channels. Completely cycle transport lift
hydraulics several times.
