Cautions

• The air compressor is not a toy and should not be used by children. It is recommended that the user be 16 years or older. Keep children at a safe distance when the air compressor is working.
• The air compressor has a built-in non-removable lithium-ion battery pack. Do not throw the air compressor into the fire or discard it. Do not expose the air compressor’s battery pack to high-temperature environments, such as leaving it in a car in direct sunlight. If the lithium-ion battery pack is exposed to extreme heat, impact, or water, there is a risk of fire, spontaneous combustion, and even explosion.
• The air compressor should not be stored at temperatures below -10°C or over 45°C. Exposure to extreme heat or cold will shorten the air compressor’s service life and damage the built-in battery pack.
• Leaving the air compressor unused for long periods may harm the battery, so it is recommended to charge the air compressor at least once every three months.
• The air compressor uses a built-in DC motor which may produce electrical sparks when running and should never be used in flammable or explosive environments.
• If the air compressor makes an unusual noise or starts to while running, turn it off immediately.
• Always make sure the correct air pressure unit is selected before seeing the air pressure to prevent accidents such as a burst tire.
• Common unit conversions: 1 bar ≈ 14.5 psi, 1 bar = 100 kPa, 1 psi ≈ 6.89 kPa.
• Always monitor the air compressor during usage and never leave it unamended when using it without presetting pressure to avoid over-inflating.
• Only use the air compressor in a clean, dry environment. Dirt and dust getting into the air compressor may cause damage to it. The air compressor is not waterproof and does not clean it with water.
• If the air compressor doesn’t seem to function properly, reinsert the air hose and then pull it out again to restart the air compressor. If it does not function properly, please contact the after-sales service team.
• Use a Xiaomi MDY-12-EQ charger or other chargers with equivalent specifications to charge with a compliant charging cable. Issues caused by failure to charge according to the above requirements are not covered by the warranty.
• When the air compressor runs for a long period, the connection between the air hose and the air compressor will get hot. Do not touch it to avoid burning yourself.
