Adjusting Roll Gap Polyurethane Rolls - MacDon R1 Series Operator's Manual

3. Polyurethane rolls: Insert a feeler gauge through the
inspection hole in the conditioner endsheet to check the
roll gap on polyurethane roll conditioners. The factory
setting is 3 mm (1/8 in.).
4. Steel rolls: The length of thread (A) extending above the
jam nut on the adjustment rods can be used as an
approximation of the roll gap. However, this method does
NOT provide consistent roll gap measurements. The roll gap
factory setting for steel rolls is 6 mm (1/4 in.). If
adjustments are required, refer to
Steel Rolls, page 108 for adjustment instructions.
Adjusting Roll Gap – Polyurethane Rolls
Because polyurethane rolls operate at smaller gaps and the conditioning is less aggressive, the roll gap setting is more
sensitive than on steel rolls.
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.
DANGER
Ensure that all bystanders have cleared the area.
