12. adJUstiNg the PrrV ValVe
A hex wrench is used to adjust the PRRV valve and the Matrix console’s “Valve Test” is used to activate
the FieldPilot valve. Refer to the Matrix manual for instructions regarding the “Valve Test” and other valve
settings. Adjust the PRRV valve to obtain a 4 second lock-to-lock time. Turning the adjustment screw in
will decrease (make faster) the lock-to-lock time. Be sure the oil is warm and the vehicle is moving forward
slowly when setting the lock-to-lock time. Tighten the lock on the PRRV once the proper lock-to-lock is
obtained.

The steering disengage kit (GG) is used to automatically disengage FieldPilot when the steering wheel is
turned. The magnets mount on the steering shaft or other rotating part of the steering wheel and the sensor
mounts so that there is a 1/8” clearance between the sensor and magnet.
