One, Dust removal equipment comes in various types, with different models, specifications, structural performance, and functional features. It is necessary to carefully read the manual before use to prevent damage to the industrial vacuum cleaner due to improper use and to ensure user safety. Two, The operating environment temperature for standard industrial vacuums should not exceed 40 degrees Celsius, the workplace should not be above 1,000 meters in altitude, and there must be good ventilation. The drying room environment should not contain flammable or corrosive gases. Three, Dry dust removal equipment is not allowed to suck water, and the vacuum cleaner should not be operated with wet hands. If there are large paper balls, plastic sheets, or debris larger than the nozzle diameter in the area to be cleaned, they should be cleared beforehand to avoid clogging the nozzle. Four, Ensure a proper grounding to ensure electrical safety. General industrial vacuums should not operate continuously for more than 8 hours at a time to prevent motor overheating and damage. Specially designed industrial vacuums with a custom cooling system can operate continuously for 36 hours without interruption and can be used with machine tools. Five, When using an industrial vacuum with an automatic cable rewind feature, pull out the power cord to the required length of use, but do not pull it too far. If you see yellow or red markings on the power cord, stop pulling immediately to prevent overextension. To rewind the power cord, simply press the button for automatic retraction. Six, Do not overstretch or frequently bend the industrial vacuum's flexible hose, as it can affect the hose's lifespan. Seven, Check for any damage or leakage on the power plug and cord of the dust removal equipment; electrical leakage can damage the industrial vacuum's motor. Eight, When moving the dust removal equipment, be careful not to be bumped to prevent damage to the vacuum cleaner's drum and a decrease in suction power. Nine, Store the machine in a well-ventilated and dry place when not in use. Do not support continuous long-term operation of industrial vacuums; control the operating time within the supported duration of the vacuum cleaner to avoid overloading, which can affect the vacuum's lifespan. Ten, If the dust removal equipment's main unit heats up, emits a burning smell, or the industrial vacuum cleaner vibrates or makes unusual noises, immediately shut it down and have it repaired; do not overload the industrial vacuum cleaner.
