Step 3
Check the scraper blades for any nicks or signs of
wear. If any nicks are present or if the blade is worn,
replace both blades. If the blades are in good
condition, place the rear scraper blade over the rear
holding pin (knife edge to the outside). Holding the
blade on the beater, turn it over and install the front
blade the same way.

Step 4
Holding the blades in position, insert the beater
assembly into the freezing cylinder and slide it into
position over the drive shaft. Turn the beater slightly
to be certain that the beater is properly seated.
When it is in position, the beater will not protrude
beyond the front of the freezing cylinder.
