How to Disassemble, Clean and Reassemble an Apollo A7700 HVLP Paint Spray Gun

HVLP paint spray guns can last for quite some time when they are properly maintained and cared for, just like any other piece of equipment. When using the same liquid over and over again, it is fine to allow the coating to stay in the gun for a few hours in between coats. Whenever you change colors or the type of coating (i.e., primer to base coat), you should remove the needles and nozzles of the machine and clean them to ensure maximum performance. Although disassembling the machine is not required, you should be sure to remove them and clean them in order to ensure optimal results.

After every time you use your spray gun, you should disassemble it and clean it thoroughly. I have outlined a detailed guide that will guide you through the process of disassembling a paint gun and then cleaning it. The following article focuses on the Apollo AtomiZer A7700 HVLP turbine spray gun that is featured in this posting.

Why Clean Your HVLP Spray Gun?

In order to ensure that your HVLP spray gun continues to operate at its full potential, you should ensure that it is maintained regularly. The gun is going to accumulate a lot of buildup and residue over time, and this will make it harder for it to function efficiently or clog up. It’s also important to keep in mind that residue buildups can also cause corrosion, which can damage the gun and reduce its lifespan. The only way to prevent these problems from occurring is to keep your HVLP spray gun clean on a regular basis.

The cleaning of an HVLP spray gun can be done in a number of different ways. It is necessary to disassemble the HVLP spray gun and remove the cup in order to clean it. It is recommended that you use a brush to clean the nozzle and the inside of the gun of any debris that may have accumulated in them during the cleaning process. When the gun has been cleaned, it can be reassembled and tested to ensure that it works properly once it has been cleaned.

What do you need to clean a HVLP Spray Gun?

If you want to make sure your HVLP spray gun is thoroughly cleaned, you will need the following supplies in order to do so.

  • Water

  • You can use a bucket or any other container of your choice

  • The cleaning solution (either a commercial cleaning solution, or a mixture of dish soap, water, and a commercial cleaner)

  • The brush should be soft (in order not to scratch the gun)

  • In order to reach places that are difficult to reach with a toothbrush,

  • A rag or a paper towel would be ideal

  • Gloves that can be thrown away

As the first step of the cleaning process, you’ll need to pour your cleaning solution into a bucket, along with some water according to the directions on the cleaning solution bottle. Wearing disposable gloves is the next step you need to take. The gun should be soaked in a smooth cleaning solution for several minutes, then it should be drained and then dipped back in the liquid where it can soak for some more time.

It is recommended that you let it soak for a few minutes before wiping the gun down with a rag or paper towel. Then, take a clean rag and wipe the gun clean with it before you put it away and rinse it off with clean water to get the gun clean.

Steps for cleaning the cup and assembly:

  1. After cleaning your solution with acetone or lacquer thinner, or adding it to a bowl with several ounces of gun cleaning solution, the solution should be cleaned again.

  1. Make sure the gravity cup or pressure cup attached to the siphon-feed mechanism is removed.

  1. The paint gun cleaner kit includes a brush which can be dipped into the system and brushed on the outside of the cup with the brush provided in the kit after the solution has been dipped into it. Then you are going to dry the area off using a paper towel or a shop towel after the area has been cleaned. If you want to be sure you get all the way under the cup’s rim, be sure to do so.

  1. If the cup you are using has a Teflon lining, you should not leave acetone in it. It is inevitable that Teflon will deteriorate over time as a result of acetone use.

  1. You will need to use the wrench to remove the cup assembly.

  1. My previous step was to remove the Air Feed Connector (A5211), and also the check valve as well as the tubing of the air feed system. Several drops of cleaning solution will have to be poured through the filter as part of the cleaning process. Cleaning the insides of the parts can be accomplished with the help of a small brush.

  1. The filter should be removed from the bottom of the stem once it has been cleaned (siphon feeder only). If you want to clean it, you can dip a brush in a cleaning solution and clean it with a dry cloth.

  1. If you have a brush, you can use it to clean the gasket that has been removed from the assembly.

  1. It is important to clean both the inside and outside of the cup as well as the underside of the lid under the gasket.

  1. The siphon feed stem needs to be cleaned inside and out with the help of the long brush.

  1. The Air Connector on the top of the assembly can be cleaned with the small brush that comes with the assembly.

  1. At the bottom of the stem, replace the gasket and the filter by reinstalling the gasket and the filter

Steps for disassembling and cleaning the spray gun:

  1.  Using the gun cleaning solution, remove the following parts from the gun and soak them in it:

  2. A7501-NS, A7501-GK, and A7502 are all uninstalled and should be removed from the air cap by unscrewing and removing them

  3. In order to remove the needle (A7520) that is affixed to the gun at the back, unscrew the Material Adjustment Screw (A7522). As soon as the trigger is pulled, take hold of the back of the needle and pull it out.

  4. The Nozzle (A7503) should be loosen and removed by using a wrench

  5. The following pieces need to be lifted off the table and made sure to be separated from each other as soon as possible. (Note: For older models, there is a pin on the inside of the gun body, which you do not need to remove. For newer models, the pin is attached to the air distributor (A7506-NS).

  • Air Cap Seal (A7504)

    • Gasket for the air distributor (A7556)

    • Distributor of air (A7506-NS)

    • Plate for air distributors (A7507)

    • Ring for adjusting the fan speed (A7508)

    • Seal (7509)

  1. The Retaining Nut for the Air Valve (A7519), the gasket (A7518 & A7517), the Air Valve Return Spring (A7516), and the Air Valve Stem (A7515) are all removed from outside of the spray gun by using a wrench. Once removed, the retaining nut should be taken out with a wrench, and then the gasket will be removed as well. The Bushing (A7514) does not need to be removed in order for this to work.

  2. Make sure that the Material Blanking Cap (A7533) is loosely fastened to the spray gun at the front by using the wrench.

  3. It will be necessary to remove both the Gland Seal (A7527) and the Nut (A7528) in order to replace them. For this purpose, you will need to use the back end of the needle as a lever.

  4. Use the different brushes soaked in cleaning solution so as to scrub all of the surfaces inside the gun body thoroughly to ensure that the inside of the gun body is thoroughly cleaned.

  5. After cleaning the spray gun, use a soft towel to wipe down the entire body of the spray gun. When you have finished cleaning all the other parts of the machine, set it down to dry.

  6. Use the tools and brushes included in the Spray Gun Cleaning Kit in order to thoroughly clean each of the parts of the spray gun that have been soaked in the cleaning solution. All threads should be checked to ensure that there is no dried paint or other debris attached to them. All holes and apertures should be clear and all holes and apertures should have a good seal.

  7. The parts should be thoroughly dried and set out to dry for a couple of days.

  8. The outside threads on the housing of the Air Distributor (A7506-NS) are well-suited to being corroded by dry fluids, and if you pay close attention to them, you will notice that they lock the ring lock onto the threads in such a way that you cannot separate the ring lock.

  9. There is a great deal of material that tends to accumulate between the needle and the gland seal (A7527) on the end of the needle when it is being cleaned. Ensure that the entire surface of the needle is smooth and free of materials.

Spray guns need to be reassembled in the following manner:

  1. Upon completing the cleaning and drying of all the parts of the spray gun, assemble it again. The process of reassembly does not need to be done in a particular order except that the Nozzle (A7503) must be put in before the Needle (A7520) can be inserted.

  1. As the name indicates, A7501-GK is a gasket which has a thin edge and a larger flat edge, which results in a sharper edge as compared to A7501-GK. In order to place the flat edge in the groove, it must be inserted into the groove at the bottom.

  1. In order to adjust the air flow, the A7508 Fan Adjustment Ring has slots at the top and bottom of the ring, which are angled at 6 o’clock and 12 o’clock, and is screwed on. The air distribution plate’s slits (A7507) should align with the slits on the fan adjusting ring in order to ensure that the fan is properly adjusted.

  1. On older models of the Air Distributor, the top section uses four holes and the bottom section uses five holes. It will be the pin that will fill the fifth hole, the four holes in the top, and the four holes in the bottom will be left unfilled.

  1. A pin is attached to the air distributor on some of the newer models of the A7700. There should be four holes on top and four holes on the bottom of the gun body where the pin should be inserted, leaving a space inside the gun body between the two pins.

  1. Ensure that the Nozzle is replaced just tight enough so that the Fan Adjustment Ring can move freely even when the Nozzle is replaced. Binding can occur if the band is overtightened, but leaking can also occur if the band is not snugly fitting.

  1. The Air Cap Ring should be loosely seated over the Air Cap, so that the Air Cap can be used when you are not using the spray gun for a long period of time. If you do not need to use the spray gun for several days, then you can remove it. As a result, if there is still coating residue on the threads of the two parts, this will prevent them from locking together when the threads are clean. When you are getting ready to spray, make sure that you tighten it again as soon as you can.

  1. As the Gland Seal is installed first, it will face up against the Gland Seal Nut as the cone portion will be facing up against the Gland Seal Nut, while the flat portion of the Gland Seal will be facing down.

  1. The Gland Seal Nut needs to be tightened up after the Needle has been reinserted using the Wrench after the Needle has been reinserted. Initially, the screw needs to be tight enough so that the needle can be pulled out with some tension, but not too tight so that the needle gets stuck inside the gun body when it tries to be pulled out. This will ensure the needle can be pulled out with some tension. As long as the tension is correct, the material will not be able to escape through the nut.

  1. When inserting the needle spring in the spray gun, you should insert the small end first, leaving the larger end of the spring facing the back.

  1. Please be sure to apply a few drops of Spray Gun Lube to the threads before replacing the Material Adjustment Screw. Make sure the spread is even.

  1. A suitable lubricant should be used before replacing the Air Cap Ring in the Air Cap Seal assembly since the outer threads of the Seal are exposed.

It is necessary to take the following steps in order to clean your HVLP spray gun:

1. Clean out the paint cup

For your HVLP spray gun to function properly and to prevent paint buildup, you will need to ensure that it is cleaned after each use, so make sure you do this after each use. You can clean the paint cup by removing it from the gun and rinsing it with warm water before reattaching it to the gun. Depending on the stubbornness of the paint buildup, there may also be the need for a brush to remove the paint in order to clean the area. It is then necessary to dry the paint cup off and then reattach it to the gun as soon as it has been cleaned.

2. Disassemble the gun body

A proper cleaning of an HVLP spray gun begins with the disassembly of the gun’s body, which must be the first step. It will be much simpler to clean all the small pieces, the nooks, and crannies of a computer that can easily become jammed with residue over time by doing this. All parts of the gun should be immersed in a cleaning solution designed specifically for HVLP spray guns after the body has been disassembled and cleaned. As a result of the cleaning process, there is a possibility that any hardened residue that was left behind after cleaning is going to cling to any parts that have been left behind.

3. Submerge the parts in paint thinner

When you wish to clean your HVLP spray gun, there are a few steps that you must take. You must submerge it in paint thinner. It will be possible for you to break down paint as you go along and this will prevent your gun from getting clogged up with paint or any other substances that may be clogging it up. Then, once you have submerged each one in the solution, you should use a brush to scrub off any residue that might have remained behind after the solution has submerged them all.

Can You Use Paint Thinner To Clean Spray Guns?

A better way to clean a firearm than using lacquer thinner that has been made with automotive-grade aluminum is to use a lacquer thinner that is specifically designed for the job and is made for the job. In comparison to solvents, lacquer thinners have a higher potency and will be able to remove any buildup on your gun more effectively. In order for aluminum to stand up to the rough solvents that are used in lacquer thinners, the automotive grade aluminum must be made from a more durable material.

How do you clean a spray gun between coats?

For most painting jobs, you will need to apply several coats of paint so you can achieve the desired level of protection and the desired look. You should always clean your spray gun between coats in order to avoid any buildup or clogging of paint between coats. Taking the paint nozzle off the spray gun and rinsing it in water for a few seconds is the best way to clean it between coats. As a result, the paint will not have time to dry and clog up the nozzle as it will not dry. Once you’ve rinsed the nozzle and reattached it to the spray gun, you can continue to paint your project as soon as you’ve reattached it to the gun.

What Solvent Cleans HVLP Guns?

If you want to clean your spray gun, acetone is one of the best solvents to use. With the help of a clean rag or paper towel, the nozzle can be cleaned quickly and easily, thus removing any paint that may have clogged up your gun or other debris that may have clogged it up. As acetone is a natural solvent, it can also be used to clean, which makes it a good choice for cleaning since it won’t leave behind residue after you’ve cleaned with it since it is a natural solvent.

Can I use alcohol to clean the paint sprayer?

A paint sprayer can be cleaned with alcohol by using it as a solvent. When it comes to cleaning a spray gun with stuck-on paint, rubbing alcohol is a popular household product that most homeowners use. Using a clean cloth and a clean drop of alcohol, you can wipe down the affected areas of the gun with the clean drop of alcohol that you have applied to the cloth.

Depending on how much paint is on the surface, you may have to repeat this process several times to remove all of it. Having removed the paint with a brush, rinse the sprayer thoroughly with water, ensuring that any residual alcohol that remains is removed from it.
