Paint Gun
ASSEMBLY AND OPERATION MANUAL
Thank you for purchasing the Model Maker™ DA500 paint gun.
This manual contains the instruction you need to use and maintain
your new paint gun. Read over this manual thoroughly before
operating the Model Maker paint gun.
SAFETY PRECAUTIONS
• Never spray near an open flame.
• Always wear an adequate respirator when using the paint gun.
• Always spray in a well ventilated area.
• Never spray near an item where overspray can get on them and
cause damage.
• Always properly maintain you paint gun to achieve optimal
performance and extended life of the paint gun.
• Never allow children to use the paint gun without adult supervision.
• Always properly dispose of excess paint in the proper location.
• Always use caution when handling the needle. It is extremely sharp
and easily damaged.
• Always shut off the air source before disconnecting the air hose.
• Always disconnect the air hose from the air source before
disconnecting it from the paint gun.
OPERATION
Remove the DA500 paint gun and air hose from the plastic storage
case. Thread the small end of the airbrush hose onto the included
adapter then thread the adapter onto the bottom of the paint gun. Attach
the other end of the hose to the air source (air compressor/propellant).
Make sure the hose is securely installed at both ends to prevent air
leaks. If attaching to an air compressor, set the regulator between 25
and 40 psi depending on the type of paint that you are using. This is a
general starting point and will vary from paint to paint. You will have to
find the psi setting that works best for you and your paint.
Remove the plastic color cup from the plastic storage case. Install
it onto the body of the paint gun. Make sure it is securely in place to
prevent it from falling off during use. Add the desired paint to the color
cup. Gently pull the paint gun trigger back. This regulates how much
paint is being sprayed through the paint gun. The air adjust screw
regulates the amount of air being sprayed through the paint gun.
You should practice with the paint gun on a scrap piece of
paper or cardboard. Make various strokes with the paint gun, varying
the amount of air and paint being sprayed. This will help you achieve
the desired spray pattern.
For small, thin lines, use more air and less paint, holding the
paint gun slightly closer to the surface. To achieve larger lines, add
more paint with the air.
Make sure you keep the paint gun parallel to the surface you are
painting. If you use an arcing motion it will cause the surface to be uneven
because more paint will be sprayed in the center than on the edges.
CHANGING COLORS
To change colors while using the color cup, simply drain the
excess from the color cup into an acceptable container. Then
remove the color cup from the paint gun and wash it out using
airbrush cleaner or lacquer thinner. Again, this depends on the type
of paint being used. Flush the remainder of the previous color out of
the paint gun using the necessary cleaner. Re-install the color cup
onto the paint gun and pour in the new color.
MAINTENANCE
Properly cleaning and maintaining your paint gun is vital to the
continued consistent performance of the paint gun. The paint gun
must be thoroughly cleaned out after each use to prevent dried paint
in the passages.
BETWEEM COLORS
If you are using water based paints:
After you have finished spraying a color, you should detach the
color cup and spray the remaining paint in the paint gun onto a scrap
piece of paper. Then flush the paint gun out with airbrush cleaner.
(Window cleaner will act as a suitable substitute.) When flushing the
paint gun out, make sure to spray both fine and broad patterns,
working the needle back and forth. This will help get as much of the
leftover paint out as possible.
If you are using a paint that requires lacquer thinner for clean-up:
After you have finished spraying a color, you should detach the
color cup and spray the remaining paint in the paint gun onto a scrap
piece of paper. Then flush the paint gun out with lacquer thinner.
When flushing the paint gun out, make sure to spray both fine and
broad patterns, working the needle back and forth. This will help get
as much of the leftover paint out as possible.
