The air nozzle is compatible with all Schrader Valves. For use with
cars, midsize SUVs, motorcycles, and bicycles. The large-volume
hose is only for inflating and deflating low-pressure, large-capacity
objects.

from the switch and handle. The air compressor gets hot during
use and stays hot for some time after.
Please let the pump cool for at least 10 minutes after every 15
minutes of use.
PSI, BAR, KPA, KG /CM² are the pressure units, not the pressure
levels.
Please do not use this product in the rain or near any liquids.
Do not aim the nozzle at people or any part of a human body.
This product contains small accessories which are a choking
hazard for children. Please keep out of reach of children.
Do not use this product with 24V car power. Connect the air
compressor to a 12V 15A DC cigarette lighter.
Do not drag the product by pulling the power cord or the air hose.
