1. Pay attention to waterproofing, because the shot blasting machine adopts the principle of machinery, and the power of this principle is not only some electronic equipment, but mainly the motor, so it is necessary to pay attention to waterproofing in rainy days;
 
　　2. Pay attention to lubrication. In order to make the equipment use more smoothly, it is recommended to apply lubricating oil to the mechanical connections of the equipment and the motor and other places at intervals;
 
　　3. Pay attention to maintenance. Any product needs maintenance. Just like a car, regular inspection and maintenance are required. Shot blasting machine is no exception. Regular maintenance of shot blasting machine can extend the service life of shot blasting machine;
 
　　4. Pay attention to it properly. Because the road surface engineering is generally relatively large, many companies work in 24-hour shifts, which leads to the continuous operation of the machine. It is recommended to stop the equipment properly when working in spare time.
