When using a vacuum cleaner to clean the carpet, move it in the direction of the carpet so that the dust can be kept flat and the carpet will not be damaged. Beware of using a vacuum cleaner to absorb inflammable and explosive materials, or something with a higher temperature to avoid burning or explosion. Dry vacuum cleaners should not absorb liquids. Ordinary household vacuum cleaners should also avoid absorbing metal chips as much as possible. Otherwise, it will easily damage the vacuum cleaner and affect performance. If the dust bag is found to be damaged, it should stop vacuuming immediately and replace the dust bag immediately. Avoid dust damage to the motor. It should not be used for a long time.
If the dust accumulates on the filter bag after a period of use, the suction will drop. At this time, the box can be shaken and the dust is shaken at the bottom of the box, and the suction is restored. If there is too much dust in the dust bag or dust bucket of the vacuum cleaner, remove the dust as soon as possible and keep the dust bucket clean so as not to affect the vacuuming effect and the heat dissipation of the motor. When abnormal noise occurs during vacuuming, or when not vacuuming, check it in time, or take it with a vacuum cleaner. Keep it in a dry place. Do not wipe the switch with a damp cloth when cleaning, otherwise it may cause leakage or short circuit. The motor has a thermal shutdown function, which is self-protection of the machine, not a problem. After the machine is turned on, the motor runs at high speed (around or so), and a certain amount of heat is generated. Under normal conditions, the temperature rise is about two degrees, and the protection temperature is two consecutive minutes. When the motor generates heat, it drives the front impeller to operate.
The suction generates a large amount of air from the air inlet duct. The air flows through the motor and is exhausted from the rear exhaust to remove heat. Simply put, the motor is cooled by the air. When your motor is overheated, please check all the air inlet pipes, including the brush head, steel pipe, hose, dust bucket (dust bag) and filter element. After the cleaning is completed, the machine can be used again after a minute of rest. Use a vacuum cleaner and handle it gently to avoid impact. After use, the debris in the barrel and the dust attachments and dust bag should be cleaned up in time. And after each work, clean, check for perforation or air leakage, and thoroughly clean the dust and dust bags with detergent and warm water, and air dry, avoid using dusty dust bags. Note that the hose should not be folded and folded frequently, and should not be excessively stretched and bent. In general, the vacuum cleaner should be stored in a dry and ventilated place. Do not use a vacuum cleaner to breathe gasoline, banana water, cigarette butts and broken glass, needles, nails, etc.
Do not absorb wet objects, liquids, sticky objects and dust containing metal powder to avoid damage to the vacuum cleaner and accidents. During use, once foreign matter is found to block the pipette, it should be shut down immediately to remove foreign matter and continue to use. When using, fasten the hose, nozzle and connecting rod interface, especially the small gap nozzle, floor brush, etc. Pay special attention to stop it every half hour if it is used for a long time. Generally, continuous work should not exceed hours. Otherwise, continuous operation will cause the motor to overheat. If the machine does not have automatic temperature drop protection, it will easily burn the motor and affect the service life of the machine. If the main unit is hot, emits a burnt smell, or has abnormal vibration and noise, it should be repaired in time, and should not be used barely.
