Therefore, you must read the instruction manual carefully before using the purchased vacuum cleaner to avoid damage to the vacuum cleaner and endanger personal safety due to improper use.

3. Before use, the hose should be properly connected with the suction port of the shell, and the hose should be tightly connected with each section of the super-long nozzle and the nozzle at the end of the nozzle, such as furniture brushes, crevice nozzles, floor brushes, etc. Due to the fewer air inlets of the crevice nozzle, the noise during use is high, and the continuous use time should not be too long.
4. Connect the ground wire to ensure the safety of electricity. The vacuum cleaner should not be used continuously for more than 1 hour each time to prevent the motor from overheating and burning.
5. When using a vacuum cleaner equipped with an automatic reeling device, just pull out the power cord for a sufficient length. Do not pull the power cord over the head.

There is a circular hole in the elbow with an adjustment ring on it. When the adjustment ring covers the hole in the elbow, the suction is maximum, and when the adjustment ring leaves the hole fully exposed, the suction is minimum. Some vacuum cleaners use the method of motor speed regulation to adjust the suction power.
9. When it is found that there is a lot of garbage in the dust storage cylinder, the dust accumulation on the filter should be eliminated while the garbage is removed, and a good ventilation channel should be maintained to avoid blocking the filter and cause the suction power not to drop, the motor to heat up and reduce the use of the vacuum cleaner. life.
10. After the vacuum cleaner is used for a period of time, the suction power will drop due to the excessive accumulation of dust on the filter belt.
