The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.
PREPARING TO PAINT Pusher Valve Button (optional) Attaching the Tip to the Gun GX-07 Gun model GX-07 The gun is secured when the trigger lock is at a 90° angle (perpendicular) to the trigger in either direction. Gun locked (gun will not spray) GX-08 Attaching the Return Hose 1. Be sure that the motor switch is turned to OFF. 2. Screw the brass fitting found in the literature set into the return tube port on the side of the pump and tighten firmly by hand.
3. Turn the motor switch to ON. 4. Increase the pressure by turning the pressure control knob clockwise 1/2 turn. 5. Force the inlet valve to open and close by pushing on it with a screwdriver or the eraser end of a pencil. It should move up and down about 1/16 of an inch. Continue until water or oil is sucked into the sprayer. This will wet the moving parts and break loose any old paint residue.
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. Priming the Pump 1. Turn the pressure control knob counterclockwise to its lowest pressure setting. 2. Turn the PRIME/SPRAY knob to PRIME. Even coat throughout PRIME/SPRAY Knob Approximately 10 to 12 inches Keep stroke smooth and at an even speed.
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.

Lock the gun by turning the gun trigger lock so that it is parallel to the gun body. 10. Turn the motor switch to OFF. Preparing the Sprayer for Long-term Storage 1.
