completely cooled.
Removal

Installation
NOTE: Carbide Flail Cutter drums do not require
specific orientation or direction. Carbide Millers and
Diamond Blades are directional. They should be
stacked so that the arrows on the Millers and Blades
face the same direction as the rotation of the drum.
Carbide Miller
270 and 390 models are designed for "forward cut"
grinding (the drum rotates in the same direction that it
travels). 480 and 630 models are design for "reverse (up
cut)" grinding (the drum rotates in the opposite direction
that it travels).
