Operating Instructions and Parts Manual
Be sure the electric current is the
correct voltage. If you need to use
an extension cord, be sure it is at
least 12 gauge wire and has a
correctly grounded outlet.
3. Select a safe, well ventilated area
where you will spray your work
piece. Locate your turbine unit
away from the area where you will
be directly spraying. Do not cover
or enclose the turbine. It is
important to draw cool/ambient air
through the unit for optimum
performance. Avoid placing the
turbine in a warm environment or
in direct sunlight.
FAMILIARIZING YOURSELF WITH
YOUR SPRAY GUN
HVLP Spray Gun:
1. Slide the lever to one side, releasing
the cup from the holding pins on
the cup. Reverse the procedure to
install the cup onto the gun body.
Make sure the cup is secure. Be sure
the cup is centered on the gasket
under the top of the cup.
2. Familiarize yourself with the
controls on the spray gun. There
are three main controls: rotating air
cap, material flow knob and air cap
locking ring. Click the rotating air
cap into each position: horizontal,
vertical and 45°. When the air cap is
in the 45° position the pattern is
round. This is useful for spraying
small, narrow pieces of work. Paint
flow will increase when using the
diagonal position. It is usually
necessary to reduce the paint flow
by adjusting the flow knob. (See
Figure 2)
3. Turn the material flow knob
counterclockwise to open or release
more fluid, clockwise to reduce or
close material flow.

4. Loosen the air cap locking ring one
or two turns. This will feather the
top and bottom of the fan pattern
and slightly reduce the fan pattern
size.
COATINGS
COATING PROPERTIES: Coatings are a
blend of resins and additives to create
a product that will provide a protective
and beautifying surface to your work
piece. Different resins have different
properties. It is important to use the
correct coating to achieve a desired
result. Manufacturers of coatings can
control the resin solids content,
production viscosity, sheen, color, flow-
out enhancement and other
properties. Some products offer ways
to adjust the coating properties such as
speeding up or slowing down the
drying time, adding catalysts to
strengthen the molecular bond or
adding flattening agents to lower the
sheen. Manufacturers will often give
some guidelines on how to thin their
product for spray application.
There are many different types of spray
equipment in use. Coating
manufacturers cannot address all of
them. Make sure you know about
your spray equipment. Make sure to
use the correct fluid viscosity to
produce the best possible results.
YOUR CHOICE OF COATINGS AND
VISCOSITY: Extremely thin, watery or
light bodied fluids such as inks, aniline
dyes and oil stains can generally be
used straight from the can. Most water
based finishing products are also
formulated to be used straight from
the can without thinning with a 3
stage or larger turbine. Most other
coating products will need to be
thinned anywhere from 10% to 50%
depending on the available air
pressure of the turbine model and the
properties of the coating selected (see
