Checking the Main Arms
The 6 main arms pivot freely horizontally and vertically
to allow the unit to follow the contour of the ground.
A bronze bushing is pressed inside the pivot holes
between the main arm and mainframe. The bronze
bushing is 3 mm (1/8 inch) longer than the thickness
of both plates combined. Tighten the 5/8 x 2 inch bolt
against the bushings, not the arms, to allow it to pivot
freely

Adjusting the Springs
The purpose of the springs is to distribute the weight
evenly and reduce the shock load on the pivot points.
The springs are adjusted evenly across to level the
unit. Use the nuts on top of the spring rod to adjust
the springs
(Figure
Important:
Do not adjust the spring so that the
coils are completely compressed. Allow at least
1.6 mm (1/16 inch) of space between coils.
