Spraying
NOTE: When spraying block filler, mastics or high solid coating, leave out the gun filter and high pressure filter screens.
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.
Even coat throughout
Approximately 10 to 12 inches
Keep stroke smooth and at an even speed.
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.

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.Turn the PRIME/SPRAY valve 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.
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.
Do not flex wrist while spraying.
Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker than the other.
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.

WARNING
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.
CAUTION
The pump, hose, and gun should be cleaned thoroughly after daily use. Failure to do so permits material to cake, seriously affecting the performance of the unit.
