Revision B
6.12.5 Adjusting Deck Height
The draper seal is the gap between the draper and the cutterbar. It should be inspected before the draper is operated to
prevent potential damage to the draper system.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
’
s seat for any reason.
WARNING
To prevent bodily injury from the fall of a raised reel, always engage the reel safety props before going under the
raised reel for any reason.
IMPORTANT:
The draper seal is set to 0
–
3 mm (0
–
1/8 in.) at the factory to prevent material from entering into the side drapers and
stalling them. Whenever you are installing new drapers, the draper seal MUST be set to at least 1 mm (1/16 in.). This is
because new drapers are very tacky and can cause material to accumulate on the underside of the cutterbar, which can
cause the draper to rub against the cutterbar and thereby cause the hydraulic pressure in the draper circuit to increase to
dangerous levels. A gap of 1
–
3 mm (1/16
–
1/8 in.) is acceptable. Follow this procedure to check the gap; adjust the gap if
necessary.
1. Lower the header onto blocks.
2. Engage the reel safety props. For instructions, refer to Engaging Reel Safety Props, page 31 .
3. Shut down the engine, and remove the key from the ignition.
