4.2 Preparing Wings for Installation
CAUTION: FOR SAFE HANDLING, TIE INNER & OUTER
BOOM SECTIONS TOGETHER TO PREVENT
ACCIDENTAL UNFOLD DURING INSTALLATION.
1. Tie outer boom sections to inner section.
2. Attach lifting chain at lift point (A) on
inner boom section. Position chain
between vertical and angled boom
members so chain does not move
from this point when boom is lifted.
4.3 Installing Boom Wings
1a. HY BOOM - Fit nut (1) washers (2) to the threaded end of the tie
rod. Fit the rod under tab on mount plates on center frame. Fit
remaining washers and lock nut to the rods.
1b. HZ BOOM - Attach tilt cylinders to center frame using pins and
cotter pins. Remove plugs from cylinder ports and manually
extend cylinders to their full extension. Install 0-ring washers and
restrictor fittings in both ports on hydraulic cylinders. The restrictor
with the small hole is fitted to the fixed (base) end of the hydraulic
cylinder. Fig. 7.
2.
Position boom hinge on center frame
with folded boom sections to the front.
3.
Attach tie rod/tilt cylinder to hinge pin
and cotter pins.
4.
Line up lower hinge pin holes and insert
pin. Insert threaded pin from the front
through the center frame and hinge and
retain with lock nut.
5.
Attach safety chain from center section to extended pin on upper
end of hydraulic cylinder - Fit locking ring to pin. This will prevent
boom sections from accidentally unfolding during installation.
6.
Repeat steps 3-6 for other wing.
7.
Attach equalizer cables to inner boom sections using M12x50mm
bolts and lock nuts.
8.
Install 0-ring washers and restrictor fittings in both ports of
hydraulic fold cylinders. Restrictor with small hole goes in the fixed
