Bleeding the Transport Lift Hydraulics
Refer to Figure 2-13:
1.
Start with the transport axle in the lowered (field) po-
sition, 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 cylin-
der and the base end hose fitting on the box lift cylin-
der 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 fit-
ting and proceed until both fittings have been tight-
ened. Completely extend the transport lift cylinders
and IMMEDIATELY lock the cylinders up by flipping up
the cylinder lock channels on both transport lift cylin-
ders and the box lift cylinder at the middle of the
tongue.
!
WARNING!
NEVER CRAWL UNDER THE DRILL IN THE RAISED POSI-
TON 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 trans-
port 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 cyl-
inders until oil appears at the loosened hose fittings.
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 cyl-
inder lock channels. Completely cycle the transport lift
hydraulics several times.
