1.
Start with the transport axle in the lowered (field)
position, and the box lift cylinder (at the middle of
the tongue) completely retracted. Loosen the base
end hose fitting at the elbow on the left transport lift
cylinder and the base end hose fitting on the box lift
cylinder at the middle of the tongue.
2. Slowly supply oil to the base end of the transport lift
cylinders until oil appears at the loosened hose fit-
tings. Oil may not appear at both location at same
time. As oil begins to appear at a fitting, tighten that
fitting and proceed until both fittings have been
tightened. Completely extend the transport lift cylin-
ders and IMMEDIATELY lock the cylinders up by
flipping up the cylinder lock channels on both trans-
port lift cylinders and the box lift cylinder at the mid-
dle of the tongue.
NEVER CRAWL UNDER THE DRILL IN THE RAISED POS-
ITON WITHOUT THE CYLINDER LOCK CHANNELS IN
PLACE.
3. When the cylinder lock channels are in place,
loosen the rod end hose fitting at the elbow on the
left transport lift cylinder and the rod end hose fitting
on the box lift cylinder at the middle of the tongue.
4. Slowly supply oil to the rod end of the transport lift
cylinders until oil appears at the loosened hose fit-
tings. As oil begins to appear at a fitting, tighten that
fitting and proceed until both fittings have been
tightened.
5. Extend the transport lift cylinders, and remove the
cylinder lock channels. Completely cycle the trans-
port lift hydraulics several times.
