Operating Procedures
The Model 751 has been selected to illustrate the
step
−
by
−
step operating procedures for all models
contained in this manual. These models, for all
practical purposes of operation, are the same.
Each unit stores mix in a hopper. The mix then flows
by gravity through an air tube down into the freezing
cylinder. They all have 3.4 quart (3.2 liter) capacity
freezing cylinders. The Models 750, 751, 754, and 774
have 20 quart (18.9 liter) mix hoppers. The Models 791
and 794 have 14 quart (13.2 liter) mix hoppers.
Duplicate the following procedures, where they apply,
for the second freezing cylinder on Models 754, 774,
791, and 794.
We begin our instructions at the point where we enter
the store in the morning and find the parts
disassembled and laid out to air dry from the previous
night’s cleaning.
These opening procedures will show you how to
assemble these parts into the freezer, sanitize them,
and prime the freezer with fresh mix in preparation to
serve your first portion.
If you are disassembling the machine for the first time
or need information to get to this starting point in our
instructions, turn to page 30, “Disassembly”, and start
there.

Up (Model 774)
Step 1
Remove the two stainless syrup jars with topping
pumps from the syrup rail. Check the water level in the
heated syrup topping well. Make sure the water is filled
to the indicating mark on the bottom of the well. The
heated rail should have 32 oz. (946.2 ml) of water.
Step 2
Place the heater switch in the ON position.
Note: This heating process will take approximately
2
−
1/2 hours to reach temperature. The water level in
the topping wells must be checked at least once daily.
Step 3
Prepare a pail of an approved 100 PPM sanitizing solu-
tion (examples: 2
−
1/2 gal. [9.5 liters] of Kay
−
5
or
2 gal. [7.6 liters] of Stera
−
Sheen
). USE WARM WA-
TER AND FOLLOW THE MANUFACTURER’S SPE-
CIFICATIONS. Sanitize the topping pumps by placing
the entire pump assembly in the pail of sanitizing solu-
tion. Pump the solution through the assembly to thor-
oughly sanitize the pump.
Step 4
Remove the two topping pumps. Fill each stainless
syrup jar with topping. Replace the topping pumps in
the syrup jars.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
MAKE SURE POWER SWITCH IS IN THE
“OFF” POSITION! Failure to follow this instruction
may result in severe personal injury from hazardous
moving parts.
Step 1
Lubricate the groove and shaft portion that comes in
contact with the bearing on the beater drive shaft. Slide
the seal over the shaft and groove until it snaps into
place. DO NOT lubricate the hex end of the drive shaft.
Fill the inside portion of the seal with 1/4” more
lubricant and lubricate the flat side of the seal that fits
onto the rear shell bearing.
