- Firmly connect the pump's nozzle to the tire valve.
- Double-click the power button to start the inflation. The pump will begin to inflate the tire.
- Monitor the tire pressure manually by feel, as this model does not have a pressure display.
- Once the desired pressure is reached, single-click the power button to stop the inflation.
- Carefully disconnect the pump from the tire valve. For Presta valves, tighten the nut.
Note: Always start the pump before connecting it to the nozzle if the tire is completely flat (non-flat tire start before connecting to the nozzle).
