Auto-Lift System
Function
The auto-lift mechanism consists of a motor , a cam,
and two micro switches. The cam lifts the draw arm,
and the switches control rotation of the cam. One
switch stops the draw arm when it is in the raised
position. The other switch stops the draw arm when it
is lowered. These two switches are controlled by the
foot pedal switch.
Figure 2.
When the foot switch is pressed, the coil of the lift relay
is energized and the switch points start the lift motor .
The motor runs until the return switch roller drops into
the cam notch. Once this occurs, the motor
discontinues with the draw arm in the raised position.
When the foot switch is released, the lift relay returns
to its rest position. The motor runs until the front or lift
switch roller drops into the cam notch.
Note: The auto-lift will operate in the AUTO or W ASH
positions.
Lift Motor
A disc type brake is mounted to the lift motor armature.
This brake keeps the motor from “free-wheeling” after
the power supply is disconnected, and allows the cam
to stop at the correct position. When either of the cam
switches stop the power supply to the lift motor, a
spring moves the armature backward to engage the
disc brake. When power is supplied to the motor , the
torque moves the armature forward which overcomes
the spring tension and separates the discs. The motor
also is protected thermally with an automatic reset.

Auto-Lift Relay
The auto-lift relay (encased in a clear, plastic housing)
is located in the upper control panel and is mounted
into a plug type socket base. The wires are connected
to the socket base.
The auto-lift relay is an ordinary double pole, double
throw relay. It controls the auto-lift system. The relay
coil is energized by the foot switch. When the foot
pedal is pressed, the relay energizes and supplies
power to the auto-lift motor assembly. When the foot
pedal is released, the relay de-energizes.
If the relay does not operate, the auto-lift system will
not work. If the relay sticks in the energized position,
the draw arm will be held in the raised position. If this
occurs, place the control switch in the OFF position.
This will discontinue beater operation and syrup
delivery.
