4.1 Inflation
Attach the correct nozzle to the inflation port (usually the top or designated inflation side). Insert the nozzle into the valve of your inflatable item. Press the power button twice to activate the pump for inflation. The pump will deliver 500 L/min airflow at 5.0 kPa pressure for rapid inflation. Once inflated to the desired firmness, press the power button once to turn off the pump.
