The gauge will indicate the pressure of the tyre when it's aerating.5. Pay attention to the pressure gauge， usually you can stop after 2 to 3 minutes(comes to 206KPA).Notes:- When use it， please start the car engine to enhance power， don't consume car battery power.- The machine only can be used by DC 12V/15A power， don't use it with domestic high voltage 24V， 36V， 110V， 220V.- When pump the tire， please stop for cooling purpose after working for continuous 10 to 15 minutes. When pumping the rubber dinghy， it can work continuously for 30 minutes.- For general tyre， it can reach 206 KPA normal tire pressure in 2 to 3 minutes， but for big tyre， it may need longer time.- After starting aeration， if the instrument pointer rapidly rise， it may indicate that the air wasn't filled into tire， at that moment， it should be stopped and restarted， otherwise， instrument and the motor will be damaged. - When using the air compressor， you'd better pay attention to tire pressure in case that the tire was supersaturated.- Keep the vehicle's cigarette lighter receptacle clean and fuse connected， otherwise the compressor can not work.- This item should avoid damp， heavy cast and sand mud invasion; please keep the child from playing with it.Package Included:1 x Air compressor 3 x Pneumatic Nozzles
