On the high side of the header, make
one
small
(1/4
–
1/2 turn)
counterclockwise
adjustment to nut (A). Do
NOT
make any further adjustments to the float lock nut on
this side of the header yet.
IMPORTANT:
Adjustment of more than two turns in either direction may
adversely affect the header float.
NOTE:
Turning the float lock nut clockwise raises that side of the
header; turning it counterclockwise lowers that side of the
header.
NOTE:
Set screw (B) does not require loosening for adjustments of
up to one-half turn of nut (A).
7.
Make the same adjustment to the float lock nut on the low
side of the header in the
counterclockwise
direction. For
example, if an adjustment of 1/4 turn counterclockwise was
made on the high side of the header, make an adjustment
of 1/4 turn clockwise on the low side of the header.
