CONTROLLING THE FLUID
If a fluid pressure tank is used, the amount of fluid can be
controlled by regulating the pressure on the tank. The
amount of fluid can also be controlled by means of the fluid
needle adjusting screw. By turning it clockwise (to the
right), the amount of fluid is reduced. Turning it counter
clockwise (to the left) increases the amount of fluid.
HINTS FOR GOOD SPRAYING TECHNIQUES
At all times hold the spray gun perpendiculartothesurface
being sprayed. A spraying distance of 6-8 inches is
recommended. This distance can be varied depending on
the item being sprayed, the material or the air pressure
used. Release the trigger at the end of each lateral stroke
while the gun is still traveling. Start the gun moving at the
beginning of the next stroke so the gun is in motion when
the trigger is pressed (see illustration). This action should
be practiced until a smooth, steady, rhythmic stroke
becomes natural.

Overlap each stroke 50%. This is done by aiming the gun
at the edge of the last stroke. A short practice period will
be necessary to achieve an even stroke. Avoid arching the
gun as this will leave an uneven coat of paint (see
illustration).
To Clean Gun: Spray a small amount of clean solvent
through the gun. Never immerse the gun in solvents as this
removes lubricants and dries out the packings. A caustic
solution should not be used to clean gun, as this will
destroy the aluminum alloy. Remove air nozzle and wash
it in solvent. If necessary to clean air nozzle holes, use a
broom straw or toothpick. Never use a steel wire or hard
instrument as this will result in distortion of spray pattern.
Wipe exterior of gun with solventsoaked cloth. Never soak
gun in liquid detergent.
To Lubricate gun: After each day's use place a drop of
oil at trigger screw, fan control packing, and fluid needle
packing. Occasionally remove fan control spring and
recoat with a light grease or Vaseline.
MAINTENANCE
Proper adjustment of your Craftsman Detail
Touch-Up Gun will give you a normal spray
pattern of this shape (see illustration). If not,
consult service check listen next page.
NOTE: If water is used as a solvent, clean
the gun, and spray paint thinner or mineral
spirits through the gun after cleaning to
remove any excess moisture and protect
parts.
