Raven SmarTrax Installation Manual page 26

Once user is ready to manually control the steering control valve, it is important that the user
measure the amount of time it takes for the wheel to turn all the way from the left to the right.
If the time is more or less than 15 seconds, the valve must be adjusted!
For times less than 15 seconds, the valve spool stop must be turned in to slow the
valve speed. To do this, user must first loosen the acorn covers on each side of the
valve. Once these covers are removed, loosen the jam nuts and turn in the spool stop
using an allen wrench. Once adjusted, reset the jam nut and put the acorn cover back
onto the valve.
Left and right lock to lock times are set independently by each spool stop.
For times more than 15 seconds, the valve spool stop must be turned out. Repeat the
same process as stated above to adjust spool stop.
Once the valve has been adjusted, tighten down the spool stop acorn cover.
WARNING! Failure to secure the spool stop adjustment screw with the jam nut and
acorn cover could result in a loss of auto steering.
Once the valve has been adjusted, return the wheels to the center position and turn tractor
OFF.
