10.9 Checking Roll Gap

The correct roll gap is required for proper conditioning. The setting is different for steel and polyurethane rolls.
DANGER
To prevent injury or death from the unexpected startup of the machine, stop the engine and remove the key from the
ignition before you leave the operator's seat.
1. Lower the header to the ground.
2. Shut down the engine, and remove the key from the ignition.
3. Steel rolls: The length of thread (A) extending above the
jam nut on the adjustment rods can be used as an
approximation of roll gap, but does NOT provide consistent
roll gap measurements. To ensure that the roll gap is at the
factory setting, refer to
Rolls, page 126.
4. Polyurethane rolls: Insert a feeler gauge between the rolls
from either front or rear of header. The factory setting is
3 mm (1/8 in.). If adjustments are required, refer to
Adjusting Roll Gap – Polyurethane Rolls, page
