Applicable models: universal

Precautions
1. Unit conversion 1kgf/cm2=98kpa
2, normal maintenance of the car, should be measured once a month tire pressure


Steps

1. Unscrew the cap of the tire valve.

2. Screw the copper head of the tire pressure gauge into the valve and tighten it.

3. The tire pressure gauge will display the tire pressure.

4. If the tire pressure is insufficient, please add gas. If the tire pressure is too high, please press the bleed valve to fine-tune the pressure.

5. After the measurement is completed, unscrew the copper head and press the bleed valve to zero the pointer. Screw back the original tire valve cover
