Using the Aerogogo Giga Pump 17 is a breeze. First, connect the appropriate nozzle to the item you want to inflate. For safety, start at the lower level (6kPa pressure and 300L/min flow) to prevent over - inflation. If you need faster inflation, switch to the higher level (17kPa and 450L/min). To use the light, just turn it on and select one of the three brightness settings according to your needs. When it comes to charging, use the proper charger for the built - in 12V 2600mAh rechargeable battery. Keep the pump dry and store it in a cool, dry place. After each use, make sure to check the nozzles for any blockages and clean them if necessary. Avoid dropping or rough handling of the pump to maintain its performance.
