MAINTENANCE AND SERVICING
5.7 Operator’s Station
5.7.1 Seat Belts
• Keep sharp edges and items that can cause damage away from the belts.
• From time to time, check belts, buckles, retractors, tethers, slack take-up system and mounting bolts for damage.
• Replace all parts that have damage or wear.
• Replace belts that have cuts that can weaken the belt.
• Check that bolts are tight on the seat bracket or mounting.
• 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.
5.7.2 Safety Systems
Perform the following checks on the operator’s presence and engine lock-out systems annually or every
500 hours—whichever occurs first.
Checking Operator Presence System
1. While the windrower engine running, place the ground speed lever (GSL) in NEUTRAL and turn the steering
wheel until it locks.
2. With everyone clear of the machine, engage header drive switch:
a. After header drives are running, stand up out of the seat. In approximately 5 seconds, the header should
shut off.
b. If NOT, the Operator Presence System requires adjustment. See your MacDon Dealer.
NOTE: To restart the header, move the HEADER DRIVE switch to OFF position and back to the ON position again.
3. With the engine running, position the GSL in NEUTRAL and in N-DETENT:
a. Swivel the operator’s station, but do NOT lock into position.
b. Move GSL out of N-DETENT. The engine should shut down and the lower display will flash “LOCK SEAT
BASE —> CENTER STEERING WHEEL —> NOT IN NEUTRAL”.
c. Swivel and lock the operator’s station and the display should return to normal.
d. If the engine does NOT shut down, the seat position switches require adjustment. See your MacDon Dealer.
4. With the windrower moving at less than 5 mph (8 km/h):
a. Stand up out of the seat.
b. The cab display module (CDM) will flash “NO OPERATOR” on the upper line and “ENGINE SHUT DOWN
5…4…3…2…1…0” on the lower line accompanied by a steady tone. At “0”, the engine shuts down.
c. If the engine does NOT shut down, the Operator Presence System requires adjustment. See your
MacDon Dealer.
5. With the windrower moving at more than 5 mph (8 km/h):
a. Stand up out of the seat.
b. The CDM should beep once and display “NO OPERATOR” on the lower line.
