IMPORTANT NOTES!
The automatic overload protection shuts the motor o when the resettable circuit
breaker pops out. It does so to protect the motor from overheating. If the motor
shuts o, it could be do to:
• Recipe being too thick
• Recipe having too many ingredients in it.
• Recipe was being processed too long at too low a speed
Thermal Protector: The thermal protector may shut the motor o to protect
it from overheating. To restart, wait for motor to cool down with the power o
(up to 45 minutes). Cooling may be quickened by placing the motor base in a cool spot.
(Unplug first.) To speed up the process, try circulating the air with a vacuum or fan
aimed at the bottom of the base. If the motor seems to be overheating but the thermal
overload protector has not turned the machine o, stop the machine and remove the
container from the base. Set the dial to #10 for the Variable Speed machine or press the
pulse switch for the Programmable machine. Turn the machine on and let the machine
run for 1 minute. Be careful never to touch any moving parts while in use.
If both protection devices are activated, follow the instructions for resetting the circuit
breaker, and then cool the motor according to the instructions for the thermal protector.
