Section 2: Operation
MAINTENANCEPARTS TROUBLESHOOTING OPERATION INTRODUCTION
Before using the machine for the first time, complete
machine disassembly, cleaning and sanitizing
procedures need to be followed. Routine cleaning
intervals and procedures must comply with the local
and state health regulations. Inspection for worn or
broken parts should be made at every disassembly
of the machine. All worn or broken parts should be
replaced to ensure safety to both the operator and the
customer and to maintain good machine performance
and a quality product. Check the wear line on the auger
flights on a regular basis and replace as needed.
B. Disassemble Parts
Auger Flight Wear
Remove all o-rings from
parts by first wiping o the
lubrication using a clean
towel. Then squeeze the
o-ring upward to form a
loop. Roll the o-ring out of
the groove.
B.3
Remove the spigot extensions or rosette caps if
installed.
Unscrew the knobs on the front door and remove
the door.
B.1
1. Front Door Disassembly
Stop the clean cycle by
toggling the Clean buttons.
A.6
Remove the front door o-rings
and remove the spigots from the
front door.

OPERATIONINTRODUCTION
2. Removing Auger
Remove front auger supports and bushings and
remove the augers from the freezing cylinders. As
the augers are being pulled out, remove the plastic
flights with springs.
B.4
Unscrew springs
from the auger
flights.
B.6
Wipe any remaining
lubricant o the hex
end of the auger and
remove the rear seal
and o-ring. Wipe any
remaining lubricant o
the o-ring and auger.
B.5
C. Cleaning Disassembled Parts
Disassembled parts require complete cleaning,
sanitizing and air drying before assembling. Local
and state health codes will dictate the procedure
required. Some state health codes require a four sink
process (pre-wash, wash, rinse, sanitize, air dry), while
others require a three sink process (without the pre-
wash step). The following procedures are a general
guideline only. Consult your local and state health
codes for the procedures required in your location.
Place all parts in 90° to 110°F (32°C to 43°C) mild
detergentwaterandwashthoroughly. Use the brushes
that shipped with the machine to clean all holes in
the front door, flights, mix pickup assembly, etc.
C.1
Rinse all parts with clean 90° to 110°F (32°C to 43°C)
water. Then place all parts in a sanitizing solution for at
least 1 minute, then remove and let air dry completely
before assembling in machine.
C.2
Be sure to use the brushes that shipped
with the machine to properly clean the
parts.

Section 2: Operation
MAINTENANCEPARTS TROUBLESHOOTING OPERATION INTRODUCTION
D. Cleaning the Machine
Wrap the brush in a clean cloth and thoroughly dry
the freezing cylinder.
D.2
The exterior of the machine should be kept clean at
all times to preserve the luster of the stainless steel.
A high grade of stainless steel has been used on the
machine to ease cleanup. To remove spilled or dried
mix, wash the exterior with 90° to 110°F (32°C to 43°C)
mild detergent water and wipe dry.
Do not use highly abrasive materials, as they will mar
the finish. A mild alkaline cleaner is recommended.
Use a soft cloth or sponge to apply the cleaner. For
best results, wipe with the grain of the steel.
D.4
E. Assembling Machine
Total Blend lubricant or equivalent must be
used when lubrication of machine parts is
specified.
The USDA and FDA require that lubricants
used on food processing equipment must
be certified for this use. Use lubricants
only in accordance with the manufacturer’s
instructions.
NOTE
Install the rear seal o-rings onto the augers. Lubricate
the outside of the o-rings with a generous amount of
sanitary lubricant.
E.1
Stoelting recommends allowing the parts
to air dry before assembling.
NOTE
Using a detergent solution and
the large barrel brush provided,
clean the freezing cylinders by
dipping the brush in the solution
and brushing the inside of the
freezing cylinders.
Make sure to thoroughly clean
the rear seal surfaces on the
inside of the freezing cylinders.
D.1
Remove the drain trays from
the front of the machine.
Remove the drip tray from
the front panel. Clean and
replace the trays.
