Folding Speed with Sequence Valve
There is one adjustment screw for unfolding speed
and one for folding speed
. You can identify adjustment
screws by markings stamped in valve body.
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
