Troubleshooting
SYMPTOM CAUSE REMEDY
Ground speed reading
when truck isn’t moving
(Radar Horn Option) .
NOTE: Ground speed
reading with the
truck not moving is
fairly common and
will not total as long
as Spraybar Master
switch is OFF or in
Bar Crclt mode .
Truck parked over/near open
water or waving grass Move truck to a clean, dry, litter-free area of
pavement and check FPM reading
Loose piece of trash hung up on or
near the Radar Horn face Inspect the area near the Radar Horn face and
clean as needed
Mounting bolts on bracket of Radar
Horn are loose Tighten bolts
Radar Horn is picking up:
• PTO shaft rotation
• engine fan rotation
• engine exhaust leaks
• system vibration
NOTE: Radar Horn mountings are checked
at factory prior to shipment . All work
correctly when they leave . It may be
necessary to remount sensor at a
slightly different angle (redrill bracket) or
rotate sensor and face it towards rear of
truck at the same downward angle . The
sensor gives an absolute speed reading
so it doesn’t matter which direction it is
facing . The speed factor will have to be
recalibrated in either case, (see
Manual
Operation in Section 6) . Shielding the
radar horn from other interfering signal
inputs may also be effective .
