take them to the sink for brush-cleaning: handscrews,
freezer doors, baffle assemblies, beater assemblies,
scraper blades, drive shafts, hopper covers, front drip
tray, and splash shield.
Brush Cleaning
1. Prepare a sink with an approved cleaning solution.
(examples: Kay-5
®
or Stera-Sheen
®
). Use warm
water and follow the manufacturer’s specifications.
Important!
Follow the label directions. Too
strong
of
a solution can cause parts damage, while too
mild
of
a solution will not provide adequate cleaning. Make
sure all brushes provided with the freezer are
available for brush cleaning.
2. Return to the freezer with a small amount of cleaning
solution. With a single-service towel, wipe clean the
bearing surface. Brush-clean the rear shell bearings
at the back of the freezing cylinders with the black
