MAINTENANCE INSTRUCTIONS
4.1 PREVENTIVE MAINTENANCE
It is recommended that a preventive maintenance
schedule be followed to keep the freezer clean and
operating properly. The following steps are suggested
as a preventive maintenance guide.
WARNING
NEVER ATTEMPT TO REPAIR OR PERFORM
MAINTENANCE ON FREEZER UNTIL THE
MAIN ELECTRICAL POWER HAS BEEN
DISCONNECTED.
The United States Department of Agriculture and the
Food and Drug Administration require that lubricants
used on food processing equipment be certified for this
use. Use lubricants only in accordance with the
manufacturer’s instructions.
A. DAILY
1. The exterior should be kept clean at all times
to preserve the luster of the stainless steel. A
mild alkaline cleanser is recommended. Use a
soft cloth or sponge to apply the cleanser.
2. Using a sanitized one-pint aluminum overrun
container, skim the mix in the hopper to remove
any foam buildup (Fig. 31).
Figure 31. Skimming Hopper
3. Run a sanitized brush down mix inlet regulator
(carburetor) tubes (Fig. 32).
NOTE
When sanitizing, the skimmer, brush and the hand
that holds the mix inlet regulator (carburetor) must
also be sanitized.
4. Note any unusual noises or operating
conditions upon startup. Repair or rectify
immediately if problems exist.
NOTE
Do not use acid cleaners, strong caustic
compounds or abrasive materials to clean any
part of the freezer exterior or plastic parts.
CAUTION
INSPECTION FOR WORN OR BROKEN PARTS
SHOULD BE MADE AT EACH DISASSEMBLY
OF THE FREEZER.
B. WEEKLY
1. Check all “O” Rings for excessive wear and
replace if necessary.

bearing for wear damage (paragraph 3.8).
