Make Folding Adjustments
The first time the drill is folded, the box folding height and
transport carriers must be adjusted. The ends of the boxes
must lift high enough to clear the transport carriers when
folding. Lift-to-fold height for each box is controlled by the
tool-bar cylinders. Adjustments are made by turning an
eye-bolt adjustment at the base end of each cylinder. The
carriers must be shifted forward or back to support the
boxes during transport.
Before proceeding, read and refer to the operator’s manu-
al, Folding the Drill, “Operating Instructions.”
When first folding the drill, watch that hydraulic hoses do
not get stretched, pinched or kinked. Adjust the hydraulic
hose in the hose holder clamps as needed to give the hose
plenty of slack for raising and folding.
1. Raise the drill and engage transport locks as ex-
plained in the operator’s manual, Folding the Drill,
“Operating Instructions.”
2. Begin to slowly fold the drill, watching if the box trans-
port hooks will clear the transport carriers. The trans-
port hooks are shown in Figure 2-5.
• If the transport hooks at the end of either box
will not clear the carriers, shorten the eye-bolt
adjustment on the corresponding tool-bar cylin-
der. The eye-bolt adjustment is shown in Figure
2-4. Shorten the eye-bolt adjustment until the
transport hooks clear the carriers by one inch.
Tighten the nuts on the adjustment when you
have attained the proper length.
• If the transport hooks at the end of either box
completely swing over the transport carriers,
lengthen the adjustment eyebolt on the corre-
sponding tool-bar cylinder. The eye-bolt adjust-
ment is shown in Figure 2-4. Lengthen the eye-
bolt adjustment until the transport hooks clear
the carrier pins by one inch. Tighten the nuts on
the adjustment when you have attained the
proper length.
3. Adjust the transport carriers so the transport hooks do
not rub the carriers when you fold the drill. When fold-
ed, the hooks should rest securely on the carriers.
Slide the transport carriers forward or back as needed
and tighten into position.
NOTE: A slight turn on the eye-bolt adjustment will move
the box end a great deal.
