Pressure Relief Procedure
Be sure to follow the pressure relief procedure when
shutting the unit down for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray tips, or preparing for cleanup.
1. Lock the gun by turning the gun trigger lock to the locked
position.
2. Turn off the sprayer by moving the pump ON/OFF switch
to the OFF position.
3. Turn off the engine by moving the engine ON/OFF switch
to the OFF position.
4. Turn the pressure control knob counterclockwise to its
lowest setting.
5. Unlock the gun by turning the gun trigger lock to the
unlocked position.
4. Hold the metal part of the gun firmly to
the side of a metal container to ground
the gun and avoid a build up of static
electricity.
5. Trigger the gun to remove any pressure
that may still be in the hose.
6. Lock the gun by turning the gun trigger lock to the locked
position.
7. Move the PRIME/SPRAY valve to the PRIME position.
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.
Heavy Coat
Do not flex wrist while spraying.
Light Coat
Light Coat
Keep stroke smooth and at an even speed.
Even coat throughout
Approximately
10 to 12 inches
NOTE: When spraying block filler, mastics or high
solid coating, remove the gun filter and high
pressure filter screens.
WARNING

© SprayTECH. All rights reserved.
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 motor
switch to OFF 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 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.
