REMoVinG/REPLAclnG tHE nEEdLE And HAndLE (illustration A):
1. Unscrew the handle and loosen the Locknut #25 by turning counterclockwise. Trigger #14 and hold in Down position while removing or inserting
the needle. This assures the needle moves freely through the Trigger. Gently remove the needle, rotating if necessary, Do NOT force out!
2. A loose needle can cause sputtering if there is any air leakage around the needle and Packing & Nut Assembly #7. If there is no noticeable
drag on the needle by the packing, then tighten the Nut of the Packing & Nut Assembly #7.
3. Inspect the condition of the needle. If it is bent or misshapen in any way, replace it with a new needle. A bent needle can damage or split the
Tip #5 causing bubbles or a rough spray pattern.
4. Hold trigger in DOWN position, insert the new needle into the Rocker Assembly #19. Gently push needle through, rotating if necessary,
push gently forward until the needle stops in the front of the tip.
5. Release trigger and tighten locknut by turning clockwise.
REPLAcinG tHE tRiGGER (illustrations c-1 and c-2):
If the Trigger #14 is removed, it must be replaced inside the airbrush shell before the Rocker Assembly #19 and needle are re-inserted.
1. Hold trigger so the opening in the lever is in-line with the opening in the end of the airbrush shell (see C-2).
2. Insert trigger straight DOWN through the opening in the top of the airbrush shell (see C-1).
3. Once the trigger has been inserted into the valve casing, you will be able to press down on the tirgger and it will return to the up position
when released. Proceed to replace rocker assembly and balance of parts as above. The needle when inserted will prevent the removal of
the trigger.
REPLAcinG tHE tiP:
1. Remove handle, loosen Locknut #25 and withdraw needle about one inch (1").
2. Un-screw the Aircap Body #4 and remove. The Tip #5 can now be easily removed by hand. If stuck in shell tap lightly with wrench.
3. Place a new tip into position and tighten aircap body to shell with a wrench. Push needle forward until it seats fully forward in tip and then
tighten locknut.
AdJuStinG WoRn PAcKinG WASHER:
1. If PTFE Packing #7 becomes worn or loose it must be tightened or replaced.
2. Tighten the Packing Nut of the assembly #7 with small screwdriver. To reach packing, guts of airbrush must be removed.
3. Replace needle and make sure packing nut is not too tight. A slight resistance to movement is needed when needle is passed through.
4. Completely re-assemble guts of airbrush.
cLEAninG tHE AiRBRuSH:
1. Paint passes from the bottle connection forward so the trigger area back will most likely not need cleaning.
2. You can back flush the paint into your bottle by covering the aircap with your finger and then pressing down on the trigger and pulling
slightly back. This forces paint from the fluid passage back into the bottle. never use open cup for back flushing.
3. In between color changes or before storing the airbrush attach bottle with appropriate cleaner and spray into sink until it runs clear.
4. Remove needle and wipe clean then replace.
5. If paint has dried for a time you can remove the front tip, aircap and aircap body for soaking or soak just the front of the airbrush in cleaner.
6. Use cleaner for the material you are spraying. Keep trigger area dry if soaking.
PERSonAL SEttinGS:
Needle Adjustment Sleeve- Used to increase or decrease spring tension for the trigger pull back. Thread into the shell until the trigger
stroke feels comfortable. Threading in until it stops can cause the trigger to jam.
