ment and tip the top of the disk in or out with
respect to the drill. Tighten bolts.

mark. Loosen the upper nuts
and adjust the wrist
weldment to the desired angle and throw direc-
tion. Tighten bolts.

Dual Marker Speed
The folding speed of sequenced dual markers is con-
trolled by an adjustment at the sequence valve.
Excessive folding speed can damage markers and void
the warranty.
Refer to Figure 25
There is one adjustment screw for unfolding speed
and one for folding speed
. You can identify adjustment
screws by markings stamped in valve body.
!
WARNING
Do not adjust sequence valve while marker is in motion.
Turn adjustment screws clockwise ( : slower) to
decrease [un]folding speed and counterclockwise
(
: faster) to increase [un]folding speed.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed. Excessive [un]folding
speed could damage markers and void the warranty.
After adjusting the folding speed, tighten jam nuts on hex
adjustment screws to hold settings.
