Fill the Tank

Connect your compressor hose to the air blaster's inlet and open the valve.

Turn on the compressor an fill the tank to around 80 PSI.

Close the inlet valve and turn off the compressor.

You can remove the hose or leave it connected for quick refilling later.

Prep the Air Blaster

Close the output valve to prevent discharge during setup.

Plug in the USB C power and 12V power plugs.

Place the distance sensor so it will be tripped by your victims, er... guests!

Test tripping the sensor -- you should hear the solenoid valve click open and closed.

Time to arm it -- make sure the barrel is not facing anyone, then open the output valve. It's now armed and ready.
