ADJUSTMENT PROCEDURES
After the boom is completely assembled and before
attempting to fold the boom for the first time, the
boom should be adjusted so it lays straight both
horizontally and vertically. There are several ad-
justment points built into the boom for this purpose.
1.All adjustments must be done with the boom
unfolded and latched. Begin by adjusting the
right and left boom carrier brackets (#13 & 14 on
page 4). Adjust the brackets (#13 or 14) forward
or backward against the top tube of the boom
center section so as to act as a guide for the
center section to keep it straight up and down, not
tilting forward or backwards. When the auto-level
sway control brackets are adjusted and tight-
ened, the 1/2" x 4-1/2" bolt through the top of the
sway guide can be adjusted to snug the bracket
against the rear side of the top of the center
section tube. This adjustment should not restrict
the side to side sway of the boom but be enough
to dampen it and support the boom from exces-
sive rear forces.
3.The wings on either side must be adjusted hori-
zontally by moving the linkage mounting plate
(#10 on pages 5 & 6) up or down on the inner
hinge to get the wing level.
4.The outer breakaway hinge can be adjusted for
breakaway tension by tightening or loosening the
1/2" locknut (#16 on page 7). You may have to
adjust the lock collar down to get more spring
compression. The outer wings should be set to
breakaway after a 50 lb force or better is applied
to the wing tips. The springs should not be
compressed more than 3-1/4 inches.
5.At this time the latches should be adjusted at each
hinge so the wings will be locked securely after
unfolding. There are 1/2" bolts at each hinge
point that act as a stop. These stop bolts must be
adjusted in or out to straighten the lay of the
boom. After these bolts are adjusted, the tee bolt
in the clevis end of the latch should be adjusted to
securely latch each wing. It is important that the
latch locks over-center otherwise there will be
problems with it coming unlocked. If adjustment
is required with the latch not locking over-center
you must grind or file down the latch stop which
will then let the latch go over-center and lock
securely.
6.After the boom is setup and the storage brackets
are placed in their approximate location final
adjustments can be made by folding the boom, in
the proper procedure (see page 10), slide the
storage brackets into the exact location when the
wings are folded and tighten in place.
7.If your flotation boom is equipped with a manual
or hydraulic height adjuster the following adjust-
ments must be made. Adjust the boom carrier
brackets inwards by tightening the 3/8" x 1-1/2"
bolts that protrude sideways out through the
carrier bracket and the boom carrier, when these
brackets are snug on the height adjust tubes
tighten the 3/8" x 1-1/4" to lock these plates tight
against the boom carrier. Make sure the assem-
bly slides up and down freely on the tubes. After
this is done adjust the height adjust lock pin
brackets. Carefully raise or lower the boom
carrier so the lock pins are lined up with holes in
the upright tube. Securely block the carrier at this
level and adjust the latch pin brackets so the pin
will latch securely and easily in the holes in the
upright tubes. Tighten the 1/2" bolts holding
these lock brackets securely and make sure the
pins are securely seated in the holes before
removing the blocks.
Note: Always make sure the lock pins are
securely locked after any type of height ad-
justment or before any work is done on the
boom.
8.Make sure all fasteners are tight or at the proper
tension, and hoses are not in the path of any
folding procedures.
