TESTING
THE
CONTROL
ASSEMBLY
- The
Control Assembly should first be tested with the Mixer
in the "Off" position and disconnected from the AC
Mains.
NOTE: Before you begin this test check the condi-
tion of the Stand Mixer Power Cord and replace it if it
is damaged or defective.
e Simply move the Handle from the "Off" position
and observe each of the six speed detents.
* These should have a distinct locking action in
each of the six running positions.
* Now return the Mixer to the "Off" position and
plug it into the AC Supply.
The Mixer should not run in the "Off" position.
NOTE: The mixer must be in the "Off" position
for 5 seconds - in order to Reset.
* Carefully move the Controlto the first "Stir" speed
and confirm operation.
* Remember that ALL Speeds have a "Soft Start"
feature that automatically starts the Mixer at a slower
speed to help prevent "Splash Out".
* You should observe a slight pause as you move
' from each speed. Confirm the operation at each of the
six (Stir -2-4-6-8-10) detents of the Control.
REPLACING THE SPEED CONTROL - If replace-
ment of the Control Assembly is necessary, make sure
that the Mixer is unplugged from the AC Mains and
after removing the Motor Housing, remove the (2) 8-32
x 5/8" Phillips Screws that hold the Control Assembly
to the Lower Cover.
