Features：
SG-3041 series digital display electric mixer with reasonable design, novel structure, continuously variable transmission, equipped with a regulator system, microcomputer control the speed figures reliable, high precision, low noise, simple operation and safety features。use of effective, durable, safe, reliable, long-term uninterrupted operation, no load can be more than 10,000 hours continuous operation.Stirring rod made of stainless steel or Teflon material （customer self-selection）, have excellent corrosion resistance, additional configuration control box can operate away from the table. Performance, to meet your various needs of different work environment.

Use Method：
First stirring rod clamping fixture on the motor shaft，with the speed control knob to the minimum speed position，Will need to stir the solution bottle stirring bar placed Alignment Center，Then turn on the power switch, require regular operation, select the time or always open（ON），such as more dilute solution,  stirring speed can be adjusted to the 0-500 rev / min, such as a more viscous solution may be to adjust the speed at 600-3000 r / min.

Note：
1．Be sure to use ground wire.
2．If mixing was unstable, turn the power adjustment support clamping head, so stirring rod concentric
3．Equipment should be kept dry.
