Full metal charging pump description.
New metal pump, pump with plastic pump is not a core class, pep talk fast, low noise, let consumers pay attention to distinguish (plastic pump power is small, and the noise is very big, usually only 3-40 w, and the metal pump power is in commonly 100 w above, inflation rate is 3 times bigger than the plastic pump).
Baby features:
1. Small size and beautiful appearance.
2. Fast speed, 5-7 minutes a completely flat tire can be filled.
3. Three kinds of gas mouth, bicycle, motorcycle, ball, and inflatable bed can also be pumped.
4. Materials: metal.
Ii. Method of use:
Take out the cigarette plug, plug directly into the car cigarette lighter, open the air pump switch, after waiting for air pump start-up, the breath of air hose at the top of the mouth plug directly into the tire valve, hear the sound of the air emission by tyres, said air has circulation, can tighten gas mouth, can be inflated, no longer leaking air at this time.
When the needle reaches the proper tire pressure (the tire pressure of the general car tire is 2.3KG/CM-- 2.6kg /CM), the plug and the gas nozzle are removed and the work is finished.
Please use the professional ball needle, connect the mouth and the gas mouth, and inflate the ball and other gas equipment.
Notes:
1. When used, please start the car engine, enhance the power, and do not consume the battery power.
2. The machine is limited to dc (DC12V 15A) power supply.
3. When inflating, please work for 10 minutes for cooling rest, which can prolong motor life. Inflatable rubber boat can work for 30 minutes in a row.
4. Generally, when the tire is inflated, it can reach 220KPA normal tire pressure in about 3-6 minutes. Big tires take a little longer. When the air is inflated, the instrument is rapidly rising, which means that the air is not filled with the tire. It must stop working and re-operate. Otherwise, the meter and motor will be damaged.
6. When using, do not leave the body, always pay attention to tire pressure, not too saturated.
7. If the cigarette lighter is not clean and does not conduct electricity, or the fuse is blown out, the machine cannot function properly. Please make sure that the cigarette holder conducts well.
8. The machine should avoid dampness, heavy fall and sand and mud intrusion, so as to avoid children playing, so as not to be damaged.
9. The machine has a large start current. Please do not turn on the power switch when the tyre is connected, otherwise it may be too large to burn the fuse. The correct operation is to turn on the power supply first. After the air pump starts to work properly, the tyre will be filled up again. If the power is switched off during operation, it should be turned on again, and the air nozzle should be unscrewed and turned on. Otherwise, the fuse of the car may be burned.
10. This machine is suitable for the inflating of cars, bicycle tires, ball classes, rubber boats and so on.
With the highway, the field, or any place, car tire suddenly leak is, can play its emergency function more.
Always have one, put it in the trunk of a car, not take up space, use it endlessly.
The car tire keeps the correct tire pressure at any time, which can save gas, protect the tire, and ensure the safety of driving.

Note: some pump barometer nominal 300 psi, just in order to guide the eye, actually impossible to such a high pressure (atmospheric pressure) 20, general tire pressure is controlled in 2.3 pressure, about 35 psi, general pump can achieve the most atmospheric pressure in 7 to 10, 100 psi
