5. Use the right tool for the job. Do not attempt to force a small tool or attachment
to do the work of a larger industrial tool. There are certain applications for which
this tool was designed. It will do the job better and more safely at the rate for
which it was intended. Do not modify this tool and do not use this tool for a
purpose for which it was not intended.

broken parts or mounting fixtures; and any other condition that may affect proper
operation. Any part that is damaged should be properly repaired or replaced by a

Mixing and Thinning Paints
Before attempting to spray any paints through the Spray Gun, dilute them accord-
ing to the manufacturer’s directions, for use with Spray Guns.
General Rules:
1. If mixing colors, only mix together the same types of paints (i.e. lacquer with lacquer
or acrylic with acrylic).
2. Thin paint according to paint manufacturer’s directions. Typically, enamel and lac-
quer paints are diluted with one part thinner to one part paint.
3. Before spraying make sure the diluted paint is thoroughly mixed.
4. Mix the paint in a clean jar. We recommend straining the paint before filling the Jar
(6).
Attaching the Air Hose (16) and the Jar (6) to the air supply
1. Fill the Jar (6) with strained paint. Do not fill over 2/3 full.
2. Carefully thread on the Jar Lid (3).
3. Attach one end of the Air Hose (16) to the Air Inlet (15) on the Air Brush. Attach the
other end of the Air Hose (16) to the regulator (not included) which then attaches to
the air supply using the 1/4” NPT Adapter (17). The air source must be adjustable
between 15 and 50 PSI. Thoroughly read the instructions and safety warnings
provided with the air compressor and air regulator before using.

Adjusting Paint Flow and Air Flow
1. Use the air regulator (not included) to regulate air flow. You must purchase a regu-
lator that can be adjusted to between 15 and 50 PSI. Since there is no pressure
gauge you will have to test the Air Brush on a piece of scrap material to determine
the desired setting.
2. On the Air Brush, turn the Fluid Cap (1) to adjust paint flow. For maximum flow,
turn the cap counterclockwise. For minimum flow, turn the cap clockwise. See
FIGURE 1 on page 4 and the assembly drawing on page 6.
Spray Painting
1. In a well ventilated area, press the Lever (9) to test the spray on test material. Hold
the Air Brush six inches from the material and make the necessary adjustments.
2. Practice spraying even strokes to avoid drips.
Note: Since enamels and lacquer paints dry quickly, do not leave the Air Brush for more
than a few seconds or the paint may dry and clog the Air Brush.
3. Have a spare Jar (6) filled with thinner or water, depending on the type of paint be-
ing sprayed.
4. When finished spraying, release pressure on the Lever (9). Immediately remove
the paint jar from the Air Brush and attach the spare Jar (6). Continuously spray
on scrap white paper until the paint residue in the Air Brush is sprayed out.
Cleaning
1. Remove excess paint from the Jar (6) and clean thoroughly.
2. Spray thinner or water (depending on the paint used) through the Air Brush until it
is entirely clean. Plug up the Fluid Cap (1) with a soft cloth and force air and solu-
tion through the cap and tip.
Troubleshooting
If the Air Brush becomes clogged, disconnect from the air source and clean as
stated above. Next, gently un-thread (counterclockwise) the Fluid Cap (1) and Air
Tip (7). Clean the parts in thinner and replace.
