DO NOT perform this procedure
without using a sling to prevent injury. Augers are
heavy and extra care must be taken to remove and
replace.

standing beside the paver, rmly grasp the outer
auger end and carefully pull out.
NOTE: The sling will need to be repositioned as you
carefully slide out the auger.
Be extra careful and mindful of the
paver frame and screed endgate position when
moving the auger away from the machine to prevent
falling or tripping while carrying the heavy auger.

auger end with the set screw.
