Manually rotate the mill’s yoke in the horizontal position. Lock the milling chamber by engaging the Locking Bar, part 44. Loosen the mill’s locking T-screw in the yoke’s side and let it swing vertically. Remove the lid and rotate the milling chamber upside down to remove the ground media. Reverse the operations once the milling chamber is refilled with new media.

Warning: Remember to retract the Locking Bar, part 44 before closing the doors and starting the motor. Failure to retract the Locking Bar will cause damage to the machine and/or serious injury.

Grinding Chamber Rotation:

Note that the grinding chamber must always rotate counterclockwise to prevent any loosening of fasteners. To check the chambers direction of rotation, run it at the maximum rpm setting while empty, then open the door quickly to check the rotation direction.
