OPERATION
Prepare the work piece to be painted 1.
according to paint manufacturer’s
directions. Prepare your paint mixture
according to paint manufacturer’s
directions.
NOTE: In most cases, paint must be
thinned for proper spraying. Be sure
to use a thinner recommended by the
paint manufacturer.
Fill the Paint Cup (35) no more than 2.
2/3 full with your paint mixture. Screw
the Reservoir into the Reservoir Cap
(32) being sure the Reservoir Seal
(33) is in place.
Turn on your air compressor, 3.
and adjust the regulator to the
recommended pressure (20 - 45 PSI).
IMPORTANT:4. Before applying paint to
your work piece, test spray a piece of
scrap material. In most cases both the
paint mixture and spray pattern will
have to be adjusted for best results.
To spray, squeeze the Trigger (26), as 5.
you move the Sprayer past the work
material. Release the Trigger (26) at
the end of each pass. Repeat until
you have proper paint coverage of the
work piece.
When you have completed painting 6.
your project, disconnect the Sprayer
from its air pressure source and
immediately clean following the
directions in the Maintenance section
on page 8.
Painting Tips
Successful spray painting is a
skill which requires knowledge of your
equipment, familiarity with your paint
materials and experience. Differences in
paints, work materials and environmental
conditions make every painting task
unique. For best results, practice with your
painting mixture on a scrap piece before
beginning to paint your work material.
It is critical that the surface be
properly prepared before painting. It
will be difcult to achieve a satisfactory
painted surface if the original surface is
dirty, rough or wet.
Paint Mixture
Each paint mixture will vary. You
may use solvent or water based paints.
Each of these causes a different paint
viscosity, and has a different ow rate and
drying time. High viscosity is thick, like
syrup. Low viscosity is thin, like water.
The purpose of the solvent is to
make the paint liquid so it can be applied.
Once applied, the solvent evaporates,
leaving the pigment and its binders in
place. The solvent is also used as a clean
up medium. Paint mixtures which are to
be sprayed are generally less viscous
(thinner) than mixtures which are to be
applied with a brush. Thus you will most
often have to add extra solvent to a paint
which is to be sprayed.
When paint is sprayed, it is broken
into tiny droplets, then blown by high-
pressure air onto the surface. During this
spraying process, the surface of each
paint droplet will begin to dry. When it hits
the work material, the droplet must liquefy
again, and mix with the droplets hitting
alongside it. Ideally, these droplets will mix
evenly forming a smooth surface.
If the paint mixture is too thick, the
droplets will not form a smooth layer, and
the resulting surface can be described
as “pebbly” or “orange peel”. If the paint
mixture is too thin, the paint will run,
forming long drips before they are thick
enough to form a satisfactory coat. Vertical
