First, various vacuum cleaners of different models and specifications have different structural performance and functional characteristics. Therefore, it is necessary to read the instruction manual carefully before using the selected vacuum cleaner to avoid damage to the vacuum cleaner and endangering personal safety due to improper use.
Second, the vacuum cleaner should be used in a dry room or similar environment where the altitude does not exceed 1000 meters, the ventilation is good, the ambient temperature does not exceed 40 ℃, and the air is free of flammable and corrosive gases.
Third, before use, the hose should be properly connected to the suction port of the housing. The hose should be screwed tightly to each section of the super-long nozzle and the nozzle at the end of the nozzle, such as furniture brushes, gap nozzles, and floor brushes. Since there are fewer air inlets from the slit nozzle, the noise is higher during use, and the continuous use time should not be too long.
Fourth, connect the ground wire to ensure safe electricity use. The vacuum cleaner should not be used continuously for more than 1 hour at a time to prevent the motor from overheating and burning.
Fifth, when using a vacuum cleaner equipped with an automatic cord reeling device, pull out the power cord for a sufficient length of use. Do not pull the power cord too far. If you see a yellow or red mark on the power cord, stop Pull out. When you need to rewind the power cord, press the button to automatically retract it.
Sixth, vacuum cleaners generally have two switches, one on the housing of the vacuum cleaner and the other on the grip handle of the hose. When using it, turn on the sky switch on the housing first, and then turn on the switch on the grip handle. switch.
Seventh, in normal use, be careful not to get the vacuum cleaner with water, and you cannot operate the machine with wet hands. If there are large pieces of paper, paper balls, plastic cloth or things larger than the diameter of the straw in the cleaned area, they should be removed in advance, otherwise it will easily cause the suction pipe to be blocked.
