High-precision tire jade test table Monitor car tires / prevent tire wear / reduce the risk of punctures Raw material: alloy zinc + hose + soft rubber Installation method: direct use Applicable models: all models under 7 seats High-precision tire pressure gauge dual scale Bar outer circle reading PSI inner circle reading Wear-resistant shockproof rubber sleeve High quality rubber ring, drop-resistant and beautiful The dangers of too high or too low inflation pressure Too high or too low tire pressure can easily lead to a flat tire during a prolonged driving.In order to prevent unnecessary things from happening, tire pressure detection is indispensable. Metal body is more durable Wearing handle air is made of metal material for longer life Zero air valve Thick metal, comfortable to touch, easy to use, reset and deflated Snap-on metal gas nozzle One-touch press back/easy operation/strong abrasion resistance/durable Package includes:< /p> 1 * pressure gauge (digital display) Instructions: 1. Unscrew the tire valve cap; 2. Attach the pressure measuring head of the tire pressure gun to the valve; 3. The gauge will display the tire pressure; 4. If the tire pressure is insufficient, please add air, if the tire pressure is too high, please press the deflation reset valve to adjust the appropriate tire pressure; 5. After the measurement is completed, press the release valve, reset the pointer to zero, and screw the original tire valve cap back on; Precautions: 1. The vehicle should be parked on level ground and the tire pressure should be measured when the vehicle is cold; 2. First check if the tire pressure gun reading is at "0" position, if not, please clear it; 3. First check the tire pressure valve cover and align the pressure measuring nozzle of the tire pressure gun with the valve on the tire to press vertically. The pressing speed should be fast, so as not to cause air leakage into the tire; 4. While forcefully pressing the tire pressure, observe whether the pointer is stable, quickly withdraw it after the pointer is stable, then take a reading (usually a stable tire pressure reading can be obtained immediately) 5. Check the tire pressure at least once a month, and you may measure it several times before you know how to measure the tire pressure to make sure the reading is correct.
