5.12.5 Adjusting Deck Height
Maintain the deck height so that the draper runs just below the cutterbar. With a new header or newly installed
draper, set the initial gap to 1/8 in. (3 mm). To prevent material from entering the drapers and cutterbar, you may
need to decrease the deck clearance to 0–1/32 in. (0–1 mm) after the initial break-in period of approximately
50 hours.
DANGER
To avoid bodily injury or death from unexpected start-up or fall of raised machine, always stop engine,
remove key, and engage safety props before going under header for any reason.
