7.7 OPERATOR’S STATION
7.7.1 SEAT BELTS
Keep the operator and trainer seat belts in good
condition as follows:
a. Keep sharp edges and items that can cause
damage away from the belts.
b. From time to time, check belts, buckles, retractors,
tethers, slack take-up system and mounting bolts
for damage.
c. Replace all parts that have damage or wear.
d. Replace belts that have cuts that can weaken the
belt.
e. Check that bolts are tight on the seat bracket or
mounting.
f. Keep seat belts clean and dry. Clean only with a
soap solution and warm water. DO NOT use
bleach or dye on the belts, as this may weaken
the material.
7.7.2 SAFETY SYSTEMS
Perform the following checks on the Operator’s
presence and engine lock-out systems annually,
or every 500 hours - whichever occurs first.
7.7.2.1 Operator’s Presence System
a. With the windrower engine running, place the GSL
in Neutral, and turn the steering wheel until it
locks.
b. With everyone clear of the machine, engage
header drive switch:
1. After header drives are running, stand up out
of the seat. In approximately 5 seconds the
header should shut off.
2. If not, the operator presence system requires
adjustment. See your MacDon Dealer.
NOTE
To restart the header, the operator must
move the header engage switch to “OFF”
position and back to the “ON” position
again.
c. With the engine running, position the GSL in
Neutral and in N-DETENT:
1. Swivel the Operator’s station, but do not lock
into position.
2. Move GSL out of N-DETENT. The engine
should shutdown, and the lower display will
flash “LOCK SEAT BASE ---> CENTER
STEERING WHEEL ---> NOT IN NEUTRAL”.
3. Swivel and lock the Operator’s station, and
the display should return to normal.
4. If the engine does not shutdown, the seat
position switches require adjustment. See
your MacDon Dealer.
d. With the windrower moving at less than 5 mph (8
km/h):
1. Stand up out of the seat.
2. The CDM will flash “NO OPERATOR” on the
upper line, and “ENGINE SHUTDOWN
5…4…3…2…1…0” on the lower line
accompanied by a steady tone. At “0”, the
engine shuts down.
3. If the engine does not shutdown, the Operator
Presence System requires adjustment. See
your MacDon Dealer.
e. With the windrower moving at more than 5 mph (8
km/h):
1. Stand up out of the seat.
2. The CDM beeps once and displays “NO
OPERATOR” on the lower line.
3. If not, the Operator Presence System requires
adjustment. See your MacDon Dealer.
7.7.2.2 Engine Interlock
a. With the engine shutdown, and the header drive
switch engaged, try to start the engine. If the
engine turns over, the system requires
adjustment. See your MacDon Dealer.
b. With the engine shutdown, steering wheel not
centered, and the GSL in neutral but not in N-
DETENT, try to start the engine. The CDM will
flash “NOT IN NEUTRAL” on the display upper
line, and “CENTER STEERING WHEEL” on the
lower line, 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 N-DETENT, steering wheel locked
in the CENTER position, and the header drive
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 is out of the N-
DETENT.
• The machine should not move with the engine
running and with the steering wheel still
centered, when the GSL is pulled straight out
of N-DETENT (not in forward or reverse).
