micro motor matters need attention

Precautions for Using Sander
1. Please use the foot switch as much as possible when using it. Do not use the red manual switch to control the motor, so as to prevent the motor from burning out due to sudden power failure or forgetting to turn off the power supply due to walking away. It is forbidden to change the direction of mobile phone rotation when the mobile phone is working.

2. When the motor is not in use, the needle must be clamped to prevent bearing damage and over-tightening of the three-leaf spring when the needle is idling or locked. It is forbidden to use mobile phones without vehicle needles.

3. After the motor is used for a period of time (depending on the workload), the motor may not work. First, please check the fuse. If it is in good condition, please check whether the carbon brush of the mobile phone motor (visible when unscrewing the back cover at the tail of the motor handle) is worn out and replace the spare carbon brush.

4. Don't drop your cell phone on the ground.

5. Please do not change the working voltage of the motor, which is 220V ~ 230V.
