Solution . . .
• Check to see if unit is securely plugged into an electric outlet.
• Check to see if the integrated circuit breaker has tripped and reset it, if needed.
• Check to see if the fuse for the electric outlet has blown or if a circuit breaker
has tripped.
• If the motor stops during operation due to overheating, unplug and allow the unit
to cool down for 15 minutes. Plug unit back after 15 minutes to resume normal
operation.
• Check to see if enough liquid has been added to the ingredients. Mixture should
be fluid and free-running at all times.

assembly daily. Replace cutter assembly at least every 90 days or sooner if cutter
assembly appears worn or damaged.
