Setup
Charging the Device
Before first use, fully charge the Bullseye Pro Tire Inflator's Lithium-Ion battery. You have two charging options:
- Home Charging: Use the provided 1-meter USB-type home charger to connect the device to a compatible USB power adapter (not included) or port.
- Car Charging: Use the provided 3-meter cigarette lighter car charger to power the device directly from your vehicle's 12V accessory outlet. This option allows operation even with a low or depleted battery.

Attaching the Hose and Nozzles
- Screw the flexible air hose securely onto the inflator's air outlet.
- For specific inflation needs (e.g., sports balls, pool floats), select the appropriate nozzle attachment from the storage compartment located at the bottom of the device.
- Attach the selected nozzle to the end of the air hose.
Operating Instructions
1. Power On/Off
Press and hold the power button (usually marked with a power symbol) for 2 seconds to turn the device on or off. The LED screen will illuminate, displaying the current battery level and default pressure unit.
2. Setting Desired Pressure
- With the device powered on, press the 'M' button to cycle through measurement units (PSI, BAR, KPA, KG/CM) until your desired unit is displayed.
- Use the '+' and '-' buttons to adjust the target pressure. The display will show the set pressure.

3. Connecting to the Item
Connect the air hose (with appropriate nozzle, if needed) securely to the valve stem of the tire or inflatable item. Ensure a tight seal to prevent air leakage.
4. Starting Inflation
Pull the trigger to begin inflation. The device will display the real-time pressure as it inflates. The inflator will automatically shut off once the preset pressure is reached.

5. Using the LED Light
The device features built-in LED lights at the head to illuminate your work area. Press the light button (often indicated by a lightbulb icon) to turn the lights on or off. This is particularly useful for nighttime or low-light conditions.
