into the cylinder by placing the rear blade
on the bottom of the cylinder. This will
center the beater and allow alignment
with the drive coupling. Rotate the beater
assembly while pushing, until the shank
has engaged the drive shaft.

head bushing and place on the end of the
beater shaft assembly by lifting the shaft
up until the bushing slides in place.
ALWAYS make sure the head bushing
is positioned on the beater shaft
properly. Operating the freezer with
a missing or badly worn bushing
will damage the beater, head and
cylinder.
