1. With the engine shut down and the HEADER ENGAGE
switch (A) engaged, try to start the engine. If the engine
turns over, the system requires adjustment. See your
MacDon Dealer.
2. With the engine shut down, the steering wheel NOT
centered, and the ground speed lever (GSL) (B) in NEUTRAL
(but NOT in PARK), try to start the engine. The Harvest
Performance Tracker (HPT) will flash NOT IN NEUTRAL and
CENTER STEERING WHEEL, accompanied by a short beep
with each flash and the engine should NOT turn over. If the
engine turns over, the system requires adjustment. See
your MacDon Dealer.
A properly functioning system should operate as follows. If not, see your MacDon Dealer.
• The starter should engage ONLY when the GSL is in PARK, the steering wheel is locked in the CENTER position, and the
HEADER ENGAGE switch is in the OFF position.
• Under the above conditions, the brake should engage and the machine should NOT move after engine start-up.
• The steering wheel should NOT lock with the engine running and the GSL out of PARK.
• When the GSL is pulled straight out of PARK (NOT in forward or in reverse), the machine should NOT move with the
engine running and with the steering wheel still centered.
