Speed Adjustment
Adjust folding speed for dual markers with hex adjustment
screws on the sequence-valve body as shown in Figure 3-
17. There is one adjustment screw for raising speed (1)
and one for lowering speed (2). You can identify adjust-
ment screws by markings stamped in valve body.
Turn adjustment screws clockwise to decrease folding
speed and counterclockwise to increase folding speed.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed. Excessive folding speed
could damage markers and void the warranty.
After adjusting the folding speed, tighten jam nuts on hex
adjustment screws to hold settings.
