If your Unguator® unit does not function properly, there may be a very simple cause and remedy, which the operator or electrician may be able to rectify. Before sending the unit if for repair, please check the following possibilities:

• If your Unguator® machine fails to turn on, be sure to check that the unit is properly plugged into to properly    functioning electrical supply.

• Your Unguator® machine may have automatically shut down due to overloading. Ensure that the power supply has been    disconnected or that the machine has been switched "OFF" for a period of thirty (30) minutes during cool down.

• Unguator® E models produced before September 2002 are supplied with carbon-contact motors. After approximately    200 operating hours, the two (2) contact carbons (top motor only) need to be replaced by a technician. Included within    the base plate of the machine are three (3) pairs of replacement carbons. The replacement of these parts provides a good    opportunity to clean the commutator.

The machine display will indicate with an error message when an inappropriate mixing blade size has been selected for a given jar size, or if a new preparation is started from the final position of a previous one without selecting the „START“ position.

Operator error, operating conditions, or other forces may cause errors not covered below. In the event of an error not remedied by one of the below actions, disconnect power supply for a period of ten (10) seconds before attempting restart. If the condition continues, please contact an Unguator USA service representative.
