the outer booms can now be aligned.
2. 24-30 m Tritech booms must be 30-50 mm and
33-36 m booms must be 50 mm forward of the
inner booms.
3. To align the outer booms, the cables must
be adjusted. To move the boom forward the
front adjuster bolt must be shortened. At the
same time the rear cable adjuster bolt must be
lengthened.
4. To adjust the outer boom rearward the rear cable
adjuster must be shortened and the front cable
adjuster lengthened.
5. If the there is insufficient travel in the bi fold
cylinder to completely unfold the outer boom,
the bi-fold stopper bolt will require adjustment.
Wind the bolt in to allow the cylinder to travel
more and fold out the wing further. Make small
adjustments when winding the bolt and fold the
outer wing each time to check the adjustments
made.
The bolt must be in contact with the fold pivot
plate stop when the wing is in the working
position.

position it must saddle firmly against the inner boom.
If it is too loose, the outer boom may be damaged in
transport.

the bi-fold stopper bolt must be shortened. This will
increase the travel of the bi-fold cylinder allowing the
outer boom to fold around tighter.

also be caused to be boom.
4. To loosen the fold pressure, the bi-fold arm
stopper bolt must be screwed out, reducing fold
travel of the outer boom.
