5. Setup

5.1 Initial Charging

Before first use, fully charge the pump. Connect the provided USB charging cable to the pump's USB-C port and a compatible USB power adapter (not included). The charging indicator on the display will show charging status. A full charge is recommended for optimal battery life and performance.

5.2 Attaching the Inflation Hose

Screw the inflation hose securely into the inflation port on the top of the pump. Ensure it is finger-tight to prevent air leakage.

6. Operating Instructions

6.1 Powering On/Off

Long press the Power Button for 2 seconds to turn the pump on or off.

6.2 Connecting to the Valve

The pump is compatible with both Presta and Schrader valves. Attach the appropriate end of the inflation hose to your tire valve. For Presta valves, you may need to unscrew the valve cap and lightly press the valve stem to release any trapped air before connecting.

6.3 Setting Pressure Units and Modes

After powering on, the display will show the current real-time pressure. You can adjust the settings:

• Press the Unit Switch Button (Sun icon) to cycle through available pressure units: PSI, BAR, KPA, KG/cm².
• Press the Mode Switch Button (Arrow icon) to select an inflation mode: Road Bike, E-Bike, Mountain Bike, or Ball. Each mode may have a default preset pressure range.

6.4 Setting Target Pressure

Use the '+' and '-' buttons to adjust the desired target pressure. The pump features a memory function, meaning it will recall the last set pressure value for each mode, so you may not need to reset it every time.

6.5 Starting and Stopping Inflation

Once the target pressure is set, short press the Power Button to start inflation. The pump will automatically stop when the preset pressure is reached. To manually stop inflation at any time, short press the Power Button again.
