How To Adjust Fuji Hvlp Spray Gun?

First of all, it is necessary to know how to adjust the Fuji HVLP spray gun, to use it for spraying paint smoothly and easily.

The success of your spraying paint depends on the right adjustment of your gun.

Adjust Fuji Hvlp Spray Gun
  1. #1: Make sure, there should be no paint in the hose of the gun because it supplies warm air to the HVLP spray gun. If the paint remains there, it does not work properly.
  2. #2: For installing the hose rightly, you should thread the hose onto the turbine unit. First tighten the unit with fingers, then ¼ turn with a wrench.
  3. #3: There is an inline air valve with a turbine system that allows airflow. So try to adjust the valve just under the gun.
  4. #4: The hose is flexible at about six feet long, and more moveable than the hose of the main air supply.
  5. #5: Now install a clean filter in the turbine system. For this no special tool is required, you can do it by hand.
  6. #6: Wash the filter and hose in warm and soapy water to make it clean. Then dry it and put it back in the right place. These filters are more durable and cost-effective and can be cleaned before replacing.
  7. #7: The air cap should be compatible with your painting job. So match the air cap with the fluid you are using, whether it is thin or thick. Normally 1.3 mm air cap is used
  8. #8: When you are to change the nozzle, remove the needle first. But don’t use a wrench for this purpose because it may damage the needle. First, remove the control fluid knob and spring, then pull the trigger back a little and slip the needle outback of the gun.
  9. #9: When the needle is removed safely, remove the air cap and then the nozzle.
  10. #10: Remember that, the air cap, needle, and nozzle are a set. Don’t change and adjust them separately as they are part and parcel.
  11. #11: Adjust the fluid control knob; there is more than one knob in some guns but Fuji spray guns have one knob on the back. So turn this fluid control knob clockwise to minimize the range of motion and decrease output and turn it anticlockwise to increase output.
  12. #12: Adjust the fan pattern; there is another knob for controlling the fan. It is a little oversized and blue anodized knob placed on the side of the gun. If you adjust the position of this knob, it will make a great difference in the fan pattern.
  13. #13: Variable speed control dial; this is a very simple knob on the front of the turbine, which you can adjust for spray coating. If you want a thicker coating, it needs more pressure. You just need to turn the dial up till the finished atomizer for a smooth gun finish.
  14. #14: Ground control; always adjust the turbine unit on the ground. If you adjust it while keeping it on the workbench, it won’t give good results.
  15. #15: Finally, double-check all the adjustments and test on a piece of fine craft paper. When the hose, nozzle, needle, fan, and fluid all are rightly adjusted, your Fuji HVLP spray gun is ready to use.

How To Clean Fuji HVLP Spray Gun

After spraying with a Fuji HVLP spray gun, you need to clean your gun to keep it safe and maintain its working for the next use.

I have analyzed three levels, following which you can clean your gun well to make it fit for proper working.

Clean Fuji HVLP Spray Gun

Level #1

  1. #1: First of all, empty the cup of your Fuji spray gun thoroughly, and wash it using a rag soaked in a  solvent (water, oil, thinner, etc.).
  2. #2: Now open the valve of the fluid control
  3. #3: Fill the solvent in the cup almost ½ and spray out until you get clear solvent comes out from the gun
  4. #4: Wash the air cap, the tip of the nozzle, and the needle with this rag soaked in a  solvent

Level #2

If you want to clean it thoroughly by disassembling your Fuji spray gun, you will have to follow the pattern given;

  1. #1: Complete level 1 cleaning and separate the air hose
  2. #2: Have a tub and fill it with the proper solvent
  3. #3: Unscrew all the parts like a fluid knob, needle, spring, nozzle, etc. carefully
  4. #4: Keep the most sensitive parts separate from the other parts so they may not damage
  5. #5: Take proper brushes, and scrub each part separately when it is soaked
  6. #6: When they are clean, wash them again with fresh clean solvent
  7. #7: Dry all the parts of the gun and reassemble them according to the instruction in the manual.

Level #3

This level of cleaning is adopted when you have to change the paint type, as you are spraying water-based paint, and then all of sudden you want to spray oil-based paint.

  1. #1: First perform all the steps of level 1
  2. #2: Take some denatured alcohol and wash the fluid passages
  3. #3: Wait for a few minutes and let it work
  4. #4: It will clean the hose, nozzle, cup, and needle making it ready for the other type of paint

An Important Note;

The solvent you are using should be toxic solvent, use warm water, soap water, lacquer thinner, and a brush to clean your gun. But be careful while using this type of solvent as it may harm the lungs, skin, and eyes.

So take all necessary precautionary measures like gloves, glasses, shoes, etc. to protect yourself from the dangerous effects of the toxic solvent.
