Product description:
1. This machine is suitable for all 12V automobile tires, especially 4x4, medium buses, 2 tons of trucks, and high-grade cars, such as large tyres, large air volume, and quick charging.
2. It also applies to motorcycles, bicycles, ball games, rubber boats, beach floating beds, inflatable toys and so on.
3. On the highway, in the field or in the morning to work, the tire suddenly leak or puncture needle, more can use first aid.
4. The correct tire pressure can ensure the safety of the car and save gas, and use it in case of emergency.
5. Equipped with a full set of inflatable mouth, it can be used for tire, rubber dinghy, air cushion, inflatable toy, ball inflatable and many other USES.

[usage] :
1. Insert the air nozzle at the top of the rubber tube directly into the tire valve, and when the air is released by the tire, it indicates that the air has been circulated and the air is tightened, so that the air will not be released again.
2. Take out the power cord battery clip (without the cigarette holder plug), directly clip to the positive and negative 2 level of the battery, avoid short circuit of the touch line, turn on the switch, and then inflate. (double cylinder charging pump power is too large to be plugged directly into the cigarette lighter, and it is easy to burn the cigarette lighter and the line)
3. When inflated, the instrument pointer increases with the tire saturation, and when the pointer reaches the proper tire pressure (the tire pressure of the general car is 223kpa=35PSI), the plug and air nozzle are removed, which means the work is finished.
4. Please use the professional ball needle, plastic nipple and air nozzle attached to the machine to inflate the ball and other gas equipment.

[precautions] :
1. It shall not be used for inflating tyres in large and overweight vehicles, such as trucks, large trucks, box sets, etc.;
2. Please start the car engine to enhance the power and do not consume the battery power;
3. The machine is limited to dc (DC12V10A) power supply, and no domestic high-voltage ac (AC220V) power supply can be used;
4. When inflating, please shut down for 10 minutes after 10 minutes for cooling to prevent damage to air pump and accessories and prolong motor life. When inflatable rubber dinghy, can work continuously for 30 minutes;
5. When the general tire is inflated, about 3-5 minutes can reach the normal tire pressure of 30PSI, and the large tire will be a little longer; Such as began to inflate the instrument pointer rapidly rising to 50-100 psi, said the air is blocked, no air into the tire, the need to immediately remove the gas nozzle joint, again, otherwise the motor and the instrument is easy to damage.
6. Do not leave the body when using the time, always pay attention to the tire pressure, not too saturated;
7. After the machine is used, the air nozzle wrench must be straightened to avoid the elastic fatigue of rubber.
8. The air pump plug is filled with fuse, if the air pump does not start, please open the plug to check and replace (the fuse is 15A);
9. The machine should avoid dampness, heavy fall and sand mud intrusion, so as to avoid children playing, so as not to be damaged;
10. The pressure required for each type of tire is different. Please refer to the sign on the side of the tire or ask the manufacturer.
