How to Thoroughly Clean an Eclipse BCS

By Iwata-Medea’s Tech Support Guru Adam Rice
First, make sure you have everything you need. Also, make sure you work over a towel or tray in a well-lit area.

The List

• Towel or tray (not pictured)
• One dirty airbrush
• A bundle of round wooden toothpicks
• A bundle of cotton swabs
• An interdental brush
• The head cap wrench
• Cleaning solution
• Parts Guide

Use the appropriate cleaner for your paint. Medea airbrush cleaner is for water-based paints.

Disassembly

image

Take off the back handle (#19).

image

Loosen or remove the needle-chucking nut (#18). Remove the needle (#17).

image
Remove the needle cap (#1) and the nozzle cap (#2). Then remove the head cap (#3) – you may need to use the wrench. Then remove the nozzle (#4), it might be stuck inside the head cap or on the body, or it might just fall out.

Disassembly

image

Examine the nozzle tip. Make sure it’s a true, perfect circle with no dings, dents, tears or cracks. The red circle shows the part you should be looking at.

image

Next examine the nozzle from the side and make sure that it doesn’t flare out like a trumpet. If any of the above problems arise replace the nozzle, it cannot be fixed.

image

Use a toothpick to gently clean out the inside of the nozzle. Pay attention to the walls of the nozzle. It’s not enough that you can see through the nozzle; you have to clean the walls until they are bright and shiny.

image

Thoroughly clean out the paint passage using an interdental brush or an airbrush cleaning brush.

image

You can also clean out the bottle receiver with the brush or use a cotton swab.

Reassembly

image

The nozzle goes on first.

image

The three caps go on next. Tighten the head cap with the wrench.

image

Gently insert the needle next and also press down on the trigger at least once. Be careful not to force it. If it catches on something remove the needle and examine the airbrush to make sure everything is correctly assembled. Then reinsert it.

image

When the needle comes to a stop give it a quarter turn counter clockwise to ensure even wear on both the nozzle and the needle.

Do not push the needle to a hard stop, you might crack or deform the nozzle.

image

Then attach the needle-chucking nut and finger tighten it.

image

Next, reattach the handle. Your airbrush should now be clean.

image

Testing your cleaning job.

Here’s the method in a nutshell. Use something readily available that won’t require a rinse after the test. I normally choose water. (As a side note, the pictures are not showing an attached bottle or airhose.)

image

Attach the bottle of water where the red arrow points and the air hose to where the blue arrow points.

image

All these tests should be done while holding down the trigger for air. Just press down for air and make sure you’re not getting water.

image

Pull the trigger all the way back. You should gets lots of water.

Push the trigger all the way forward and reconfirm no water.

image

Now pull back just a little and hold the spray up to a mirror and make sure you’re getting a round spray pattern.
