Beater Rotation
Check Rotation of Beater
PLACE THE ROCKER SWITCH IN THE
“OFF ” POSITION. Failure to follow this instruction
may result in severe personal injury to fingers or hands
from hazardous moving parts.
Step 1
Remove the door assembly, the beater and the
driveshaft. Inspect each part for a smooth surface and
proper fit.
Step 2
Replace the freezer door to close the door disconnect
switch.
Step 3
Open an upper side panel and place the rocker switch
in the EJECT position.
Step 4
Check for proper operation of the belts and pulleys.

Observe the gear coupling for the driveshaft.
It should be turning clockwise as viewed from
the front of the machine.
Correct Rotation of Beater
DISCONNECT ALL POWER TO THE
FREEZER! Failure to follow this instruction may result
in electrocution.
To correct rotation on a single--phase unit, exchange
leads inside the beater motor. (Follow the directions
printed on the beater motor.)
To correct rotation on a three--phase unit, interchange
any two incoming power supply lines at freezer main
terminal block only. (Follow the directions printed on
the beater motor.)
Gear Align ment and Rear Shell Bearings
Check Gear Alignment and Rear Shell Bearings
Step 1
Open the freezer door. Insert the driveshaft through
the rear shell bearing and into the drive coupling.
Step 2
Be sure the driveshaft can easily slide in and out of the
female socket on the gear unit on all six positions of the
hex.
Step 3
If the driveshaft is binding, the gear unit could be out
of alignment. Check the set screw on the drive
coupling and the cap screws on the gear unit to be sure
they are tight.
Step 4
Inspect the rear shell bearing for tightness. Be sure the
locking tab has been folded over to prevent the nut
from loosening.
