9. 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.
Pressure Relief Procedure
Follow this procedure after the unit is assembled and before
any operation that involves the spray gun such as cleaning
and maintenance or changing tips or accessories.
1. Turn the pressure control
knob counterclockwise to its
lowest setting.
2. Turn the PRIME/SPRAY
valve to the PRIME
position.
3. Trigger the gun to remove
any pressure that still may
be in the hose.
4. Lock the gun by turning the
gun lock nut clockwise
(when looking from the back
of the gun) until it stops.
This closes the material
valve in the gun.
Injection hazard. Do not spray without the tip guard in
place. NEVER trigger the gun unless the tip is completely
turned to either the spray or the unclog position. ALWAYS
engage the gun trigger lock before removing, replacing or
cleaning tip.

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 priming 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.
