Checking Engine Interlock
1. With the engine shut down and the header drive switch engaged, try to start the engine. If the engine turns over,
the system requires adjustment. See your MacDon Dealer.

NOT in N-DETENT, try to start the engine. The cab display module (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 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).
