Connect the Air Hose to the Nozzle
Schrader Valve
| Nozzle type | Inflation connlector |
|---|---|
| 
Mountain bikes, electric bikes, motorcycles, and cars are typically equipped
with Schrader Valves.
Inflation: Connect the Schrader valve to the tire inflator.
Deflation: Use an appropriate tool (e.g. a4mm hex wrench) to press the
air needle inside the air valve.
Presta Valve
| Nozzle type | Inflation connlector |
|---|---|
Road bikes and certain types of mountain bikes may require the use of a Presta valve adapter for inflation.
Inflation:
- Attach the Presta valve adapter to the Schrader valve.
- Unscrew the Presta valve of the tire.
- Connect the Presta adapter to inflate.
Deflation: Unscrew the Presta valve, press the air nozzle to deflate.
Ball Needle
| Nozzle type | Inflation connlector |
|---|---|
| 
Use a ball needle when inflating a basketball, football, or any other ball.
Inflation: Securely connect the ball needle to the Schrader valve and insert
the needle into the ball.
Deflation: Insert the ball needle directly into the ball’s hole.
Check the Air Pressure
Press the on/off button to begin/end inflation. Once the air pressure
reaches the predetermined value, the tire inflator will cease inflating
automatically. Connect the tire inflator to the object being measured and it
will display the pressure in real-time..
DC Power
Connect the car charging cable from the vehicle’s cigarette lighter socket to
the DC port on the tire inflator. Press the on/off button to activate the tire
inflator using the cigarette lighter as a power source. Battery indicator
shows
Application Scenario Switch
Press the “M” button briefly to switch between the 5 available inflatable
scene modes.
| Scene Mode | Reference Default Values | Adjustable Range |
|---|---|---|
| Car mode | 2.5BAR | 0.1~4.4BAR |
| Motorcycle mode | 2.7BAR | 0.1~3.7BAR |
| Ball mode | 38PSI | 2~150PSI |
| Custom Mode | 100PSI | 2~150PSI |
Conversion of Units
Press and hold the “M” button to toggle between the display units for air
pressure. Refer to the following formula for unit conversion:
1PSI=6.89KPA 1BAR=100KPA 1Kg/cm’=98 KPA
Preset Pressure
Short press : If below 100 PSI, +/- 0.5 PSI. If above 100PSI, +/- 1 PSI.
Long press : To quickly adjust the preset pressure.
Note: The tire inflator will automatically save scene switching and preset pressure values.
LED Light
When on, press the “O” button briefly to activate LED lighting. One press
results in a steady light, double press activates the flashing mode. Press
once more to turn the light off.
Schrader Valve Adapter
Turn clockwise to the right to tighten the air pipe, and turn counterclockwise
to the left to unscrew the air pipe.
Pressure Reset
Upon starting up, if the measured pressure value is non-zero, simultaneously
press “+” and “-” buttons for 2 seconds to initiate an automatic reset. All
display characters will remain illuminated and the reset will be completed
after the countdown has finished.
Note: The tire inflator is reset to zero at the factory. It is not recommended to perform calibration at high temperatures.
Inflation Pressure Reference
To ensure safety, please refer to the instruction manual and other reliable
sources for the appropriate pressure before inflating. Overinflation may cause
explosions resulting in personal injury.
CarTire
The recommended pressure range for a car’s tires can be found on the tire’s sidewall. Tire inflation is dependent on the weight of the load. For more specific air pressure recommendations, consult the relevant vehicle manual.
Bicycle Tire
Bicycle tire inflation pressure should fall within the acceptable range marked on the tire’s sidewall. The inflation pressure is dependent on the weight of the load. For more detailed air pressure recommendations, consult the bicycle’s manual.
**Sports Balls
** Football, basketball, volleyball, and other ball inflation pressure is indicated near the inflation holes. Inflation pressure is influenced by the weight of the load. For specific air pressure suggestions, please refer to the relevant ball manual.
High Temperature Safety Precautions
When unscrewing the air hose, the joint and hose may become excessively hot
due to prolonged use, and it is advisable to avoid touching bare hands.

Slow Inflation
|
- Ensure the battery has sufficient power.
- Inspect the air hose for any leaks.
- Verify that both ends of the air hose are securely connected.
- Confirm whether the inflated object is experiencing any air leakage.
It has been turned on
but cannot inflate.|
- Ensure the battery has sufficient power.
- Confirm if the current tire pressure exceeds the preset value.
The preset pressure
cannot be turned up
or down.| Check ifitis in the wrong inflation mode. Select
custom mode to adjust the preset values within
the range of 2-150PSI.
Inflation is normal,
but pressure is zero.
|
- Low-pressure items, such as balloons, are not measurable with the tire inflator.
- When tires are empty, they must be inflated briefly before the tire pressure value can be displayed.
After twisting the air
nozzle, the tire inflator
has automatically shut
down.| 3 minutes automatic shutdown, long press the
start button to start again.
There is air leakage
when connecting the
air hose.| Tighten the air hose.
The color of the power
indicator in the inflation
state is different from
that in the standby
state.| During the discharge process, the lithium battery
experiences a notable decrease in voltage. As a
result, it may appear inconsistent in color between
the indicator light while inflated and in standby
mode. This occurrence is not indicative of a
malfunction.
The power indicator is
off after charging.| Replace the safety-compliant charging cable and
adapter to charge again.
