1. The pattern size can be changed using different techniques One method used to adjust the size of the spray pattern is very different to what you are used to The principal is simple The air nozzle is backed by a spring and is floating To change the size of the fan you will turn the collar 8001 clockwise or counter clockwise Winding the collar IN results ina LARGER FAN Winding the collar OUT will result ina SMALLER FAN The standard position is shown in Fig A The tip of the fluid nozzle should be flush with the aircap Winding out the collar counter clockwise causes more air to pass through the center hole and less to the horns The result is a smaller fan Fig B When the collar is screwed in air is cut off from the center hole in the air cap This redirects air to the horns resulting in a wider fan pattern Fig C Fig A Fig B Fig C You can also regulate the fan size by changing the distance from the paint surface to the air cap The closer the distance the smaller the spray pattern size and vice versa Adjusting the fluid knob to reduce paint output will also reduce the fan size Also the distance the trigger is pulled will change the size of the fan HOW TO PREVENT PAINT BACKING UP THE PRESSURE TUBE A few very simple rules must be followed in order to keep the pressure tube 2024 clear of paint Upon stopping spraying for any reason open the cup to release pressure Turn off the turbine Only then can y2.

ECTED IN THE NORMAL OPERATION OF THE MOTOR THIS COULD IGNITE THE CONTAMINANTS CAUSING A DANGEROUS EXPLOSION KEEP THE TURBINE AT LEAST 18 FEET 6 METERS AWAY FROM THE SPRAYING AREA FOR HEALTH REASONS ALWAYS WEAR A RESPIRATOR FILTER S The Q PRO Series turbines use just one large filter The turbine case does not need to be taken apart to replace the filter To remove simply turn the turbine on its side and pull the filter out Wash in solvent and dry before replacing All Fuji filters are a friction fit When replacing push the filter in by hand and finish up by using a screwdriver through the square holes to lever the filter into position The filter must fill the entire filter enclosure and always be FLUSH with the base of the turbine case The Super PRO uses 2 filters one fine and one coarse Looking from the front of the turbine please insert the fine filter to the left side near the F of Fuji and the coarse to the right side It is important to keep the turbine as far away as possible from the spraying area and workshop dust If the filters become badly clogged cooling air will be restricted this may cause serious damage to the motor The turbine must not be placed up high it must be placed on the floor HOSE CONNECTION Connect the end of the hose female connector to the turbine air outlet To connect the hose to the gun slide back the quick connect collar and push this onto the hose connector Part 8034 To discon

ISH PROBLEMS ORANGE PEEL If the finish is rough and resembles orange peel then the material is too thick It will not atomize properly and the surface will be spotty To remedy this add more thinner or appropriate solvent For fast drying products such as lacquers you may also want to add a lacquer retarder This will slow the drying time allowing the material to flow out and level nicely Retarders are available for other coatings too such as Penetrol for oil based paints or Floetrol for latex house paints NOTE With the newer water based materials orange peel is usually a result of spraying on too thick a film Try spraying an extremely THIN FILM but still WET coat With most other coatings orange peel is caused by material being too thick or not enough atomizing power This is why we suggest leaving the air control valve fully open when experimenting with a new coating material otherwise it will cause confusion If the the air control valve is fully open or perhaps removed for Latex spraying then orange peel can only be one cause the material is too thick and must be thinned GRITTY FINISH If the material is too thin it is likely to run or be over atomized producing a rough gritty finish Try thinning the product less and spraying a wetter coat BLUSHING Blushing is the common term used when the finish looks cloudy and white sometimes also called blooming It is caused by moisture and is especially a problem when o
