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.

hen you stop painting, lock the gun trigger lock, turn the
pressure control knob counterclockwise to its lowest setting
and set the PRIME/SPRAY knob to PRIME. Turn the motor
switch to OFF and unplug the sprayer.
If you expect to be gone more than 1 hour, follow the short
term clean up procedure described in the CLEANUP section of
this manual.
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. Turn the PRIME/SPRAY knob to SPRAY.
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 by turning the
switch so that it is
parallel to the handle.
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.
