1. A variety of different models and specifications of vacuum cleaners, their structural performance, functional characteristics are not the same. Therefore, the purchased vacuum cleaner must be carefully read the instruction manual before use to avoid damage and personal safety caused by improper use of the vacuum cleaner.
2. Industrial vacuum cleaners should be used in a dry room or similar environment where the altitude is not more than 1000 meters, the ambient temperature is not more than 40 degrees Celsius, and the air is free of flammable and corrosive gases.
3. Before use, the hose should first be properly connected with the shell suction inlet, and the hose should be tightly connected with each section of ultra-long nozzle and the nozzle at the end of the nozzle, such as furniture brush, slit nozzle, floor brush, etc. Because the gap suction inlet is less, the noise is higher during use, and the continuous use time should not be too long.
4. Connect the ground cable to ensure the safety of power consumption. Household vacuum cleaners should not be used continuously for more than 1 hour each time, industrial vacuum cleaners should not be used continuously for more than 8 hours each time, to prevent the motor from overheating and burning, and a kind of industrial vacuum cleaners, which can run for 36 hours continuously due to the use of special heat dissipation system, can be used with machine tools.
5. When using a vacuum cleaner equipped with an automatic winding device, pull out the power cord enough to use the length, do not pull the power cord too much, if you see a yellow or red mark on the power cord, it is necessary to stop pulling out. When the power cable needs to be rewound, press the button to automatically retract it.
6, usually use should be careful not to make the vacuum cleaner wet, wet hands can not operate the machine. If there are large pieces of paper, paper balls, plastic sheets or things larger than the diameter of the straw, they should be eliminated in advance, otherwise it is easy to cause blockage of the suction pipe.
7. When using an industrial vacuum cleaner to absorb liquid substances, the filter element should be removed to extend its service life.
8. When using, depending on the occasion of cleaning, the suction control device can be adjusted appropriately. There is a circular hole in the bend with a regulating ring, and the suction is maximum when the regulating ring covers the hole in the bend, and the suction is minimum when the regulating ring leaves the hole fully exposed. Some vacuum cleaners use the method of motor speed regulation to adjust suction.
9. When it is found that there is a lot of garbage in the dust storage cylinder, the ash accumulation on the filter should be eliminated while removing the garbage, and a good ventilation channel should be maintained to avoid blocking the filter and causing suction not to decline, motor heating and reducing the service life of the vacuum cleaner.
10. After the vacuum cleaner is used for a period of time, due to too much dust gathering on the filter belt, the suction will be reduced. At this time, you can shake the ash shaking rack on the vacuum cleaner to restore the suction. If shaking the ash frame still can not restore the suction, it means that the dust in the bucket has been filled and should be removed in time.
11 vacuum cleaner motors are mostly high-speed motors, brushes are easy to wear after long-term operation, domestic vacuum cleaners generally use a year to a year and a half should be replaced by a brush.
12. After the vacuum cleaner is used, it should be stored in a dry place. If it is placed in an excessively wet place, it will affect the electrical insulation and service life.
