Precautions for metal tire pumps

Precautions for metal tire pumps:
Power supply: Please start the car engine first to increase power and not consume the car battery. This machine is limited to DC (DC12V15A) power supply, and household high-voltage power supply cannot be used. At the same time, make sure that the cigarette lighter is well conductive. If the car cigarette lighter is not clean and not conductive, or the fuse is blown, the air pump will not operate normally.

Working time: When inflating, it is necessary to take a cooling break after working continuously for 10 minutes to extend the life of the motor; when inflating a rubber boat, it can work continuously for 30 minutes. When inflating a general tire, it takes about 3-6 minutes to reach the normal tire pressure of 220 KPA, and a large tire takes longer.

Operation specification: If the instrument pointer rises quickly when starting to inflate, it means that the air has not been filled into the tire, and it must be stopped and re-operated; otherwise, the instrument and motor will be damaged. When using, do not leave the machine, pay attention to the tire pressure at any time, and do not oversaturate it. In addition, the machine has a large starting current. Do not turn on the power switch when the tire is connected; otherwise, the car fuse may be burned out due to excessive starting current. If you need to restart the machine after turning off the power during operation, you should also unscrew the air nozzle before turning it on.
