This video shows how the fluid flow knob directly affects the trigger pressure. This is done in such a way so the amount of fluid being released is clearly visible and can precisely adjusted to a personal spraying preference.

For the trigger to release fluid, the knob has to be screwed back from the completely forward position - if the knob is screwed all the way forward, no fluid will flow. While the knob is being unscrewed, the technician can be seen pulling back the trigger allowing fluid, and continuously more fluid, to flow from the airbrush. When the trigger is pulled back as far as possible, this is the time to stop turning the adjustment knob as it will eventually screw completely off the gun. It is common for experienced technicians to unscrew the knob to the maximum trigger position, leaving it up to their feel of the trigger to determine the spray pressure manually.

Throughout the Airbrush Tanning Procedure Videos, Airbrush Tanning Manual, and just generally throughout our site, we refer to a popular airbrushing method called the circular motion technique. This technique is described as moving the tip of the airbrush in a circular motion using the hand and fingers, as the body of the airbrush is moved in a general direction with the movement of the arm. This circular pattern matched with the straight stroke produces a wider, more consistent spray than an airbrush just being moved in a line motion. The use of this technique is not mandatory or demanded, but can be quite helpful to an airbrush tanning technician.

1. Remove the solution cup assembly from the side of the airbrush.
2. Two methods can be used for step 2:
• Method 1 (NOT Recommended): Remove the airbrush handle, tail cap and fluid knob in one piece. This method is at high risk to the nozzle, as many people using this method will also reassemble with these 3 parts still together. Failing to align the back of the needle to the fluid knob correctly, many try to force it into alignment, accidentally pushing the needle through the nozzle. The nozzle, being a fragile piece, can easily crack or split and will have to be replaced.
• Method 2 (RECOMMENDED): Remove the fluid adjusting knob by screwing the back of the airbrush counter-clockwise. Remove the handle, named the tail cap in the parts diagram.
3. Remove the needle cap from the front of the airbrush. Note that the needle barely protrudes through the nozzle cap, as this will need to be replaced in the same manner later.
4. Remove the nozzle cap from the front of the airbrush. Note that the needle barely protrudes through the nozzle.
5. Remove the needle chucking nut that holds the needle in place.
6. Remove the spring case by screwing it off counter-clockwise.
7. Remove the spring.
8. Remove the needle.
9. Remove the needle chucking guide.
10. Using the small wrench that came with the airbrush, gently untighten the nozzle on the front of the airbrush.

1. Using the supplied wrench, reattach the nozzle to the front of the gun so it is snugly fit. Take care not to overtighten it, as the nozzle is delicate and can easily strip or shear.
2. Reinsert the needle chucking guide, making sure the groove faces down.
3. Reinsert the spring.
4. Screw in the spring case clockwise.
5. Insert the needle gently and use a rotating motion if you meet resistance. Do not force the needle as the nozzle is easily damaged. The needle is in place when it slightly protrudes through the nozzle.
6. Attach the nozzle cap to the front of the airbrush. This is in place when the needle protrudes slightly through the needle cap.
7. Gently screw on the needle chucking nut using a clockwise motion until it is tightly snug.
8. Attach the needle cap to the front of the airbrush.
9. Attach the airbrush handle, called the tail cap in the parts diagram.

**Attach the fluid flow knob until the threads are no longer visible. From this point, pull back the trigger and turn the knob 4 more complete turns until the knob makes contact with the trigger. The airbrush is now reassembled and ready for use.
