Charging the Air Cylinder
Using the provided USB charging cable, connect the charging cable to a computer’s USB port or use a USB wall outlet
charger. Locate the barrel jack receptacle near the bottom side of the air cylinder, then plug the barrel jack plug into the
barrel jack receptacle to begin charging the air cylinder battery.
• When the USB charging cable is plugged into a power source, a green light will light at the USB connector side of the cable.
• When the charging cable is plugged into the air cylinder, the light will turn from green to red when the battery is being
charged.
• When the battery inside the air cylinder is charged, the light will change from red to green.
Airbrush Setup Instructions
Attaching the air cylinder:
• The air inlet connection for the airbrush is located on the bottom of the airbrush under the trigger.
• Thread the airbrush onto the air cylinder by rotating the airbrush clockwise until the base of the airbrush air inlet is flush with
the air cylinder’s top and is snug.
• The paint cup caps can be pulled or pried off the cup bodies by slipping your fingernail under the lip of the lids and lifting
upward. Add the desired amount of prepared paint into the cup. Lids can then be placed back onto the cup if desired.
• If this is your first time using this airbrush, we recommend using water for the first use to gain a feel for spray patterns
produced at different distances from scrap paper, cardboard or wood and to gain a feel for the trigger action of this airbrush.
• When filling with paint, be sure to thin paint to a milk-like consistency. Most paint brands will provide directions on their
bottles for the appropriate paint thinners and ratios of paint-to-thinner or paint-to-water mix for use in an airbrush.
Operation
Understand that air passes from the air cylinder up into the airbrush when the trigger is depressed. The tool is designed to
have the airbrush allow air to exit out the front of the tool. This is where the air valve screw (25), located forward and
underneath the paint cup, comes into use. By turning and opening the valve, it allows the forward progress of the air to exit
the front and it is during this process that the paint is picked up and atomized for flow when the trigger is pushed rearward,
withdrawing the needle and opening the tip of the tool. The more that you open the valve, the more air passes through.
Using water first through the airbrush will give you a better understanding of how your tool performs.
• Press down on the trigger to activate the air cylinder, allowing airflow through the nozzle at the front of the airbrush.
• To add paint into the airflow, pull back on the trigger.
