1. At this time lower planter to the ground. This
will help stabilize the planter units during dis-
assembly. If hydraulic failure should occur
while the planter is in a raised position, the
planter could fall with the possibility of causing
bodily injury or planter damage.
2. C-clamp lower parallel arms to the planter unit
to eliminate rotation. Remove the existing 5/8"
x 2 1/4" long bolts from the front of the lower
arms taking care that the existing bushings do
not fall out.
3. Insert lower spring mount (16) between lower
parallel arms. Add one 1/4" long spacer (13) to
each side. Install the 5/8" x 2 1/2" long bolts
(20) Included in package.
4. Rotate the lower spring mount (16) upwards
until it is in contact with the mounting plate.
5. Check and tighten all nuts and bolts.
