1. If you find the stirrer vibrates violently of stops stirring, please cut off the power and inspect the bottom of the beaker to see if it is level and if its position is proper while checking the voltage to see if it is 110V±10V. Other while the irregular phenomena like above will certainly occur.

2. The apparatus can work continuously for 8 hours at a medium speed and for 4 hours at a high speed.

3. If the power is on and he indicator is not lit, please inspect whether motor when power changes and the motor is overloaded. If the fuse is damaged, replace it with the fuse supplied together with the machine or a proper one of the same specification you can find.

4. If the electric motor refuses to turn under the proper power after a long time of operation, please inspect whether the screws connected with the motor's axle are loose. When the magnet drops, please stick it with 502 glue available on the market. Pay attention to the cleaning and poles of the magnet.

5.This device cannot display temperature,If you need accurate temperature, you'd better prepare a thermometer.
