Spraying
POSSIBLE INJECTION HAZARD. Do not spray without
the tip guard in place. Never trigger the gun unless
the tip is in either the spray or the unclog position.
Always engage the gun trigger lock before removing,
replacing, or cleaning tip.
Spraying Technique
The following techniques, if followed, will assure professional
painting results.
Hold the gun perpendicular to the surface and always at equal
distance from the surface. Depending on the type of material,
surface, or desired spray pattern, the gun should be held at a distance
of 12 to 14 inches (30 to 35 cm).
Move the gun either across or up and down the surface at a steady
rate. Moving the gun at a consistent speed conserves material and
provides even coverage. The correct spraying speed allows a full, wet
coat of paint to be applied without runs or sags.
Holding the gun closer to the surface deposits more paint on the
surface and produces a narrower spray pattern. Holding the gun
farther from the surface produces a thinner coat and wider spray
pattern. If runs, sags, or excessive paint occur, change to a spray tip
with a smaller orifice. If there is an insufficient amount of paint on
the surface or you desire to spray faster, a larger orifice tip should be
selected.
Maintain uniform spray stroke action. Spray alternately from left to
right and right to left. Begin movement of the gun before the trigger
is pulled.

Avoid arcing or holding the gun at an angle. This will result in an
uneven finish.

Proper lapping (overlap of spray pattern) is essential to an even finish.
Lap each stroke. If you are spraying horizontally, aim at the bottom
edge of the preceding stroke, so as to lap the previous pattern by
50%.

For corners and edges, split the
center of the spray pattern on the
corner or edge and spray vertically
so that both adjoining sections
receive approximately even
amounts of paint.
When spraying with a shield, hold
it firmly against the surface. Angle the spray gun slightly away from
the shield and toward the surface. This will prevent paint from being
forced underneath.
Shrubs next to houses should be tied back and covered with a canvas
cloth. The cloth should be removed as soon as possible. Titan gun
extensions are extremely helpful in these situations.
Nearby objects such as automobiles, outdoor furniture, etc. should
be moved or covered whenever in the vicinity of a spray job. Be
careful of any other surrounding objects that could be damaged by
overspray.
Practice
1. Be sure that the paint hose is free of kinks and clear of objects
with sharp cutting edges.
2. Set the pressure to minimum by turning the pressure control
knob to the "MIN" setting.
3. Move the PRIME/SPRAY valve up to its SPRAY position.
4. Turn the pressure control knob clockwise to its highest
setting. The paint hose should stiffen as paint begins to flow
through it.
5. Unlock the gun trigger lock.
6. Trigger the spray gun to bleed air out of the hose.
7. When paint reaches the spray tip, spray a test area to check
the spray pattern.
8. Use the lowest pressure setting
necessary to get a good spray
pattern. If the pressure is set
too high, the spray pattern will
be too light. If the pressure is
set too low, tailing will appear
or the paint will spatter out in
gobs rather than in a fine spray.
