It's easy to use, and you'll blow everyone away … quite literally!
1.    Charge your PowerHitter (see after “Pro Tip” for details)
2.    Take the bare end of the hose and slip it firmly onto the white plug on the bottom of the pump.
3.    Take the end of the hose with the adapter and plug it into the "carb" hole on the PowerHitter.
4.    Load up your PowerHitter just like you would normally do. Gently and securely insert your goods into the holder inside the cap. Screw it in deliberately but firmly until you feel it is secure. Get it good and cherry.
5.    Screw the cap back on tightly for the perfect seal.
6.    Once you're all set, just click the red on/off button to start and end the flow of goodness and get ready to have a blast! 

Pro Tip: Keep your eye out for how fast it will burn! Make sure you swap in another before it reaches the end.
