1. Put the first section of the hair dryer and the windmill mouth, tie them tightly with iron wire to prevent them from falling, and then connect them one by one.
2. The suspension of the hair dryer should be “flat, straight, tight and stable.” Use a wire or thin steel cable to tighten the suspension. The suspension position should avoid being scratched by the car or. pressed and rubbed by other equipment and materials. Suspended separately from the cables, usually hung on the side with the dust-proof water pipe.
3. Joints between hair dryers should be tight.
4. When turning the hair dryer, make an elbow or turn slowly. Don't make blind turns.
