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.
