TIRE INFLATION
NOTICE! Do not overinflate tire, as it can rupture.The gauge on the air
compressor is for guidance only. Check pressure with a known accurate gauge.
IMPORTANT! Only inflate tires to the manufacturer’s specifications. Vehicle
tire pressures can generally be found on the tire side wall, in the handbook,
on the door pillar or on the inside of the fuel filler cap.
1. Uncoil all of the power cable on the side of the air compressor, ensuring that
all the cable is unwound. Insert the 12V DC plug into the vehicle’s 12V socket.
2. Remove the dust cap from the tire valve and store in a safe place.
3. Carefully pull out the air hose from the air compressor. Use the valve

tire pressure. It will automatically stop after reaching the preset pressure.
6. Remove the valve connector and check the tire pressure with an accurate
tire gauge.
