5. With the help of another person, place the
lower drum on the frame assembly, as shown

one M8-1.25 x 60 hex bolt on one side and

nut on the other side (
Figure 8).

8. Attach the lower end of the mixing blades
to the lower drum, placing a plastic washer
between the mixing blade and the drum
mounting holes (
Figure 10). At each attach-
ment, use an M10-1.5 x 20 Phillips head
screw on one side and a 10mm flat washer,
lock washer, and hex nut on the other side.
Leave the fasteners loose for now.
Note: Since these fasteners will be regu-
larly exposed to water, we suggest coat
-
ing them with anti-seize or bearing grease
before assembly to prevent them from rusting
together. Repeat this process on the fasten
-
ers used in Steps 9–10, as well.
