Spraying
Spraying Technique
The key to a good paint job is an even coating over the entire
surface. This is done by using even strokes. Keep your arm
moving at a constant speed and keep the spray gun at a
constant distance from the surface. The best spraying
distance is 10 to 12 inches between the spray tip and the
surface.
Keep the spray gun at right angles to the surface. This means
moving your entire arm back and forth rather than just flexing
your wrist.
Keep the spray gun perpendicular to the surface, otherwise
one end of the pattern will be thicker than the other.
The spray gun should be triggered by turning it on and off with
each stroke. This will save paint and avoid paint buildup at the
end of the stroke. Do not trigger the gun during the middle of
a stroke. This will result in an uneven spray and splotchy
coverage.

Overlap each stroke by about 30%. This will ensure an even
coating.
When you stop painting, lock the gun trigger lock, turn the
pressure control knob counterclockwise to its lowest setting
and set the PRIME/SPRAY valve to PRIME. Turn the ON/OFF
switch to the OFF position and unplug the sprayer.
Practice
1. Be sure that the paint hose is free of kinks and clear of
objects with sharp cutting edges.
2. Turn the pressure control knob counterclockwise to its to
its lowest setting.
3. Move the PRIME/SPRAY valve up to the
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.
Cleanup
Do not use gasoline to clean the sprayer.
Special cleanup instructions for use with flammable
solvents:
• Always flush spray gun preferably outside and at least one
hose length from spray pump.
• If collecting flushed solvents in a one gallon metal
container, place it into an empty five gallon container, then
flush solvents.
• Area must be free of flammable vapors.
• Follow all cleanup instructions.
The sprayer, hose, and gun should be cleaned thoroughly
after daily use. Failure to do so permits material to build
up, seriously affecting the performance of the unit.
