To Clean Clogged Passages
1. Disassemble the air brush by using the following procedure (see figure 3):
a. Remove the retaining clip (Q) from the air brush body.
b. Screw the fluid cap (P) counterclockwise then push down to release the fluid needle (R).
c. Remove the fluid needle (R) by turning counterclockwise.
d. Clean the fluid needle (R), fluid cap (P) and air tip (O) with a piece of cotton dipped in thinner or
solvent. A fine bristled brush will also work.
e. Reassemble the air brush by reversing the above procedure. Note: Make sure that the flat surface of
the fluid needle (R) lines up with the flat surface of the air brush body (see figure 4).
NOTICE: Never use metal objects to clean precisely drilled passages. Damaged passages will cause
improper spraying.
