Now it is time to work on thorough cleaning the HVLP spray gun or fuji spray. There are a lot of parts that come together to help you use the spray gun, and you will need to take them all apart to get the paint unstuck and make sure it works well. Some of the parts of gun body that you will need to clean include: 

You will need to remove the collar and the air cap from the fuji spray gun body.

After choosing the proper solvent, put some inside the air cap and let it soak to remove the paint. 

After a few minutes sitting into the solvent, you can take it out and use a scrub brush to scrub the paint off from the air cap.

You may need to put the air cap back into the solvent to let it soak a little bit longer if the paint is stuck.  

The nozzle plate will come off at the same time as the needle. You will need to take it off to remove the needle.

This needs to sit in the solvent for a few minutes too. 

You can get a large bowl of it ready with the rest of the items to ensure the paint has time to dissolve and get off the parts.

Use a brush or a toothpick to get into the small parts of the needle.  

As you are removing the items from the fuji spray gun body, you will notice a spring present that you will need to remove as well.

This spring can get full of paint and will make it harder to use the fuji spray guns. 

You can take this off too, rinse it, and add it to the solvent along with some of the other parts if there is some paint that is difficult to remove.

Use a small brush to help remove it and make it easier to keep clean.  

It is a good idea to clean out the fluid nozzle. Unscrew your fluid control knob or fluid nozzle and place it to the side before squeezing the trigger to help pull the needle out.

Place fluid control knob, along with the fluid nozzle and air cap into a bucket with the right solvent inside. 

You can soak these parts in the solvent but do not place the whole fuji spray gun inside. Instead, use a brush to help clean out the parts and make sure the paint is removed.  

You will need to use a solvent soaked rag to help clean out the residue that is in the gravity cup. First, fill the cup halfway up with some solvent and then tighten up the lid and swirl it around. 

Then attach the gun to the pressure tube or hose and fuji spray the solvent out to a waste bucket or a clean rag.

Repeat this until the solvent is clear and the pressure tube cup is cleaned out. Pour the rest of the solvent into a waste bucket when you are done, wiping the cup clean.  

Before you get started cleaning your fuji spray guns, it is important to follow some safety precautions. Some of the steps you should work on ahead of time include: 

It is best to wear some protective clothing to help with thorough cleaning process of the fuji spray gun.

This will help keep you safe and clean and will help when you use a cleaning solution to get the paint off the parts. Long pants and shirts, along with goggles and gloves, will help.  

You must take apart the fuji spray gun when you are done using it. You will need to be careful when you take the gun apart.

If you force anything too much, it could break the fuji spray gun and make it hard to use again. Instead, take it apart bit by bit and wash each part before putting it back together.  

You should keep the manual of HVLP spray gun cleaning kit on hand. This will help you take the gun apart for HVLP spray gun cleaning and put it back together in the correct order when your fuji spray gun cleaning done.

Use the manual for an explanation of how the paint gun works and to see what you need to take out to get cleaned with cleaning solution so the paint will not stick.  

As you clean each of the parts, you will need to keep them out of the way and ensure they are secure.

You do not want all of the parts to move around and get lost while you do the cleaning. 

Have a plan in place to help organize the parts and then put the whole machine back together. Waiting makes it more likely that you will lose one of the pieces. 

Once the HLVP spray gun is cleaned out well, it is time to store the machine.[1]

 If you do not store the HVLP spray gun well, it will get ruined and stop working. The best way to store it is to keep it inside, such as in your garage. A location that is insulated and heated will work the best because cold can rust it out.  

You should also take the time to remove the cup's lid and store the spray gun with the lid off. This allows any solvent in the gasket time to evaporate to maintain its shape.

Finally, lubricate the needle if you do not plan to use it for some time and then store all the parts in the same place so you can find them later.

A HVLP paint spray gun is a great option to choose, allowing you to get any room painted in no time. It is much better than using your paintbrush to get all the room to look a lot nicer.

By keeping it cleaned out and not leaving paint inside, you can ensure that your paint does not get stuck inside and ruin the machine. Take a look at some of the tips above to see how you can keep your paint gun clean and safe.
