Operating Instructions
Powering On and Off
To power on the device, press the red power button. The digital display will illuminate, showing the current pressure and battery level. The device will automatically turn off after a period of inactivity to conserve battery.
Setting Desired Pressure
Once powered on, use the '+' and '-' buttons to set your desired pressure. The display allows you to switch between pressure units (PSI, BAR, kPa) using the 'UNIT' button. Refer to your item's recommended pressure (e.g., on a tire sidewall or ball). The auto-stop function will automatically halt inflation once this preset pressure is reached.
Inflation Process
- Attach the appropriate adapter to the pump hose and then securely connect it to the valve of the item you wish to inflate.
- Set the desired pressure using the '+' and '-' buttons.
- Press the 'START/STOP' button to begin inflation. The pump will operate until the preset pressure is achieved, then automatically stop.
- Once inflation is complete, disconnect the adapter from the item's valve.
Using the LED Light
The integrated LED light can be activated by pressing the light button. This feature is particularly useful for illuminating the valve area when inflating in dark or dimly lit conditions.
