To Clean Clogged Passages
1. Disassemble the air brush by using the following procedure (see figure 3):
a. Hold fluid cap (P) and locknut (Q) with the thumb and index finger.
b. Using the wrench provided (S), place on the flat surface of the fluid needle (R) and turn counter
clockwise.
c. Remove fluid needle (R).
d. Clean the fluid needle (R), fluid cap (P) and air tip (O) with a piece of cotton dipped in thinner or
approved solvent. A fine bristled brush will also work.
e. Reassemble the air brush by reversing the above procedure.
NOTICE: Never use metal objects to clean precisely drilled passages. Damaged passages will cause
improper spraying.
