will move the complete drive assembly toward the rear of the
machine.
BY the time the product has reached the proper consistency
or hardness, the drive assembly will have moved backward
just enough to OPEN a normally closed micro switch fastened
to the support on the rear frame of the machine.
The opening of this micro §wit-chwill de-energize the coil
of the compressor contactor, which will immediately stop the
compressor. The beater will continue to run.
c ) HOW TO ADJUST THE HOM (Product temperature)
The firmness of the product depends on the .positionof the
micro switch in relation to the drive assembly. The com-
pressor must cut off when the current absorbed by the beater
motor is approximately 9/10 of the plate amperage (see F,L,S.
on the beater plate). By using a armneter across the line,
feeding the beater motor, it is possible to check the amperage
drawn by the motor at the time the micro switch opens.
If a reading indicates an amperage lower than 9/10 of the
late amperage, the micro switch OPENS too soon, and should
be moved AWAY from the fly wheel. The adjustment screw
should be turned clock-wise. The micro switch is secured to
the rectangular mounting plate where it is fastened to the
frame of the machine but is free to rotate slightly around
its retaining bolt. Rotation of the plate towards or away
from the fly wheel is achieved by turning a screw located on
the plate itself and held in that position by a spring.
As a result, the micro switch will also move in either direc-
tion allowing the desired adjustment.
Turning the adjustment screw
clockwise will move the micro
switch AWAY from the fly wheel
and the compressor wil'l run
longer and make the product
harder.
~urningthe adjustment screw
counter-clockwise will move
the micro switch CLOSER to the
fly wheel. The compressor will
run less, making the product
softer.

* * * * W A R N I N G ' * * *
THE MAXIMUM TRAVEL OF THE DISC AND CONSEQUENTLY OF THE
DRIVE ASSEMBLY, IS APPROXIMATELY 114 INCH.
IN ADJUSTING THE DISTANCE OF THE MICRO SWITCH FROM THE
DRIVE ASSEMBLY, CAREFULLY AVOID INCREASING THIS DISTANCE
BEYOND 1/4 INCH. THE DRIVE ASSEMBLY WOULD NEVER REACH
FAR ENOUGH TO OPEN THE NORMALLY CLOSED MICRO SWITCH AND
THE COMPRESSOR WOULD NO LONGER BE ABLE TO STOP.
THE ADJUSTMENT OF THE MICRO SWITCH POSITION REQUIRES
ONLY SLIGHT MOVEMENTS OF THE ASSEMBLY IN EITHER DIRECTION.
