3 TROUBLESHOOTING
Before starting to troubleshoot, check the performance of the device as follows:
3.1. Quick Performance Test
Reference
To check only the operation of the motor, you can listen to the sound of the motor rotating, even without using beaters, a power
meter, or an ammeter.
Q
Procedure
1. Connect the unit to a power meter, the ammeter of a tester, or other such device.
2. Attach the beaters to the unit.
3. Set the switch in numerical order to 1, 2, 3, 4, and 5.
Q
Check points
• Check to see if the motor rotates.
• Check to see that the beaters do not come into contact.
• Check to see that the rotation speed of the motor increases in synchronicity with the speed indicated for the switch position.
• The power consumption for each switch position is shown below.
• The above values are common to 220V and 240V.
• Compared with the above values, the actual current will tend to be lower at 220V, and higher at 240V.
The shape of the power cord plug differs according to the country (and region).
