Alignment Of Wing Assemblies; Alignment Of Intermediate & Outer Boom Sections - Hardi EAGLE 3PT Boom Operator's Manual

6.3 Alignment Of Wing Assemblies

1. With the boom unfolded (in the spraying position), check the alignment
of the intermediate section with the center frame.
2. With the fold cylinder pressurized, determine if the intermediate
section needs to be adjusted to the front or rear to come into alignment
with center frame.
Note: Because of adjustments made later, it is better to start with the
wing assemblies angled slightly to the rear.
3. Relieve pressure from cylinder by folding the boom in a few inches.
4. Disconnect cylinder rod eye (B)(Fig. 13) from the intermediate boom
section.
Note: Some cylinder rods
have a machined flat
which, if visible, can be
used for adjustments. If
using the machined flat for
adjustment, leave the rod
eye pinned to the boom
and loosen the jam nut.
5. Loosen jam nut (A)(Fig.
13) and adjust the rod eye
(B)(Fig. 13) IN to move the boom forward or OUT to move the
boom rearward. Then retighten the jam nut (A)(Fig. 13).
6. Reattach the cylinder rod to the boom and pressurize the cylinder to
check boom alignment.
6.4 Alignment Of Intermediate And Outer Boom Sections
1. Unfold the boom into
operating (spraying)
position.
2. Holding the M12x100
adjusting bolt, loosen
the lock nut (A)(Fig.14),
and turn nut (B)(Fig. 14)
so the cap of the bolt
head (C)(Fig. 14)
contacts the top stop
plate with the outer and
intermediate boom
sections aligned.
3. Check to ensure that the lock nut is tight.
