4. Before assembly, apply grease to the pivot pin
holes in each end of the pivot bar and to each
pivot pin.
5. Assemble the pivot plates to the ends of the pivot
bar, using the appropriate plate orientation and
hole position for the confi guration determined in
Step 2.
There are two pivot plates (A and B) which are
mirror images of each other. They can be turned
upside down and switched from one side of the
pivot bar to the other to provide two different
mounting positions.
In each pivot plate mounting position, the pivot
pins may be installed through one of the two lower
holes in the pivot plates for confi gurations 1 and 2.
Confi guration 3 uses only the lower hole.
This provides three different height adjustment
positions. For all confi gurations, pivot pins must be
positioned with the notches in the pivot pins facing
up and the slots in the pivot pins aligned with the
bottom holes at the rear of the pivot plates. Note
that the pivot pins are never installed in the upper
holes in the pivot plates.
