The spray gun does not give paint to the center of the stain. No paint supply to the spray gun - causes of failure

It is difficult to convey those unpleasant emotions that overwhelm the owners of expensive perfumes when there are some problems with the bottle. The most common problems are the spray leaks or the sprayer does not work. Is it possible to fix the atomizer and save valuable perfume? What if the perfume does not splatter? Do not rush to get upset, we will tell you a few secrets on how to restore the vial to working capacity.

Why doesn't the perfume sprayer work?

There are several reasons that can cause a spray gun to break. The most common are the following:

• clogging of the spray nozzle or spray tube;
• sticking or displacement of the ball inside the mechanism;
• air entering the tube, which takes the perfume from the bottle.

Do not fall into despair and throw away your favorite perfume. For any of these problems, there is a right solution. There are several ways to fix perfume if it doesn't splatter. So let's try to fix the atomizer yourself.

Clogged spray nozzles

The most common reason why a perfume atomizer does not work is that it is clogged. Most often it occurs in perfumes that are already several years old. The components of the aromatic liquid, passing through the nozzle of the atomizer, can settle inside. This oily substance will eventually clog the narrow spray opening.

What to do if the perfume stopped splashing as a result of a blockage? To resolve this issue, you need to do the following:

• remove the spray button;
• soak it in alcohol, cologne or hot water to dissolve blockage;
• clean the holes in the spray with a very thin needle;
• clean the pin of the tube with a wooden toothpick;
• thoroughly blow the mechanism or spray several times.

After the cleaning procedure, you can return the nozzle to its place and check the operation of the sprayer. If it doesn't work well enough, repeat the cleaning process.

Ball sticking inside dispenser

Another reason for the inoperability of the atomizer may be the sticking of a tiny ball that is inside. This small part can get stuck and block the flow of perfume into the atomizer opening. Let's see what to do if the toilet water does not splatter.

In this case, you can use the following effective method:

• place the perfume in the freezer for 1-2 hours;
• then check the functioning of the atomizer.

It often happens that subzero temperature has a positive effect on the ball. As a result, the atomizer begins to work obediently.

Air entering the tube

If the perfume does not puff, air may have entered the spray tube. To restore the functions of the bottle, you must:

• remove the atomizer by pulling it up. Under it is a short plastic pin;
• turn the vial over and place it on a hard surface;
• gently press the pin against the surface so that it is pressed into the vial. If necessary, repeat several times;
• at the same time, a few drops of perfume will flow out, but the air bubble should leave the tube;
• then put the spray gun back on.

If all restoration work were unsuccessful, the atomizer may have broken completely. Then it is better to replace it by pulling it out of another used bottle.

Fallback Perfume Rescue Options

In the absence of positive results after the actions taken, it is better to forget about a beautiful bottle and try to extract your favorite fragrance. What to do when the perfume sprayer is completely broken? In this case, you will have to do the following:

• remove the valve part of the spray with pliers or a can opener;
• pour the perfume into a special atomizer or another bottle.

For those who are not in the know. An atomizer is a glass or plastic container with screw-on sprayer. It can have a different volume from 5 to 100 ml. An atomizer can be purchased at any perfume department that sells perfume on tap.

If you can’t remove the valve, and the dispenser is irrevocably broken, you can use another option:

• take any jar, wash well with water, wipe dry, rinse with alcohol;
• place inverted perfume in a container, after removing the atomizer;
• press the tube to the bottom of the jar so that a strong stream of perfume comes out;
• then collect the contents with a syringe and pour into an atomizer.

That's it. We wish you success. We hope that our own experience will help to reanimate your vial.

For uniform spraying of various paintwork materials(LKM), primers, liquid putties, protective compounds and impregnation, painting devices called spray guns are used. This equipment may differ from each other not only in the device, but also in the principle of operation, which affects the quality of the applied coating.

Most often, both in the household and in the professional field, electric and pneumatic paint sprayers with different tank arrangements are used. Also, these devices may have a pressure gauge built into the handle or connected to it.

The electric spray gun consists of a plastic or aluminum housing, which contains the following elements (see figure below).

1. Electromagnet. Works in a pulsed mode, pulling the bar.
2. oscillating bar. It is attracted by a magnet and pushes the piston forward.
3. Paint regulator. Limits the mobility of the oscillating bar.
4. Nozzle. Sprays paintwork materials or other compounds.
5. Cylinder. It is the body of the pump in which the piston moves.
6. Valve. Opens and closes the paint supply.
7. suction tube. It is intended for absorption of LKM. A filter can be installed at the end of the tube.
8. piston spring. After the piston moves forward, it returns it (together with the bar) to its original position.
9. Piston. Suctions and ejects paintwork from the paint sprayer.

Also on the device there is a power button, a fitting for connecting the tank.

Airbrush worksaccording to the following principle. After pressing the start button, the electromagnet (1) receives current in short pulses. At the same time, the electromagnet either attracts the bar (2), or releases it. The range of movement of the bar, and accordingly the piston, is regulated by a screw (3). The bar, pressing on the piston rod (9), sets it in motion. The reciprocating movements of the piston suck the paint from the tank and push the composition towards the valve (6). When the piston moves forward, the valve opens and passes the paint to the nozzle (4), through which it is sprayed. With the reverse movement of the piston, which is provided by the expanding spring (8), the valve closes and the paintwork is sucked from the tank through the tube (7). Further, the process is repeated.

Important! Electric spray guns also include models with a remote compressor. In this case, the device of the spray gun is slightly different, and the principle of operation of the spray gun is similar to the operation of a pneumatic spray gun.

The tool is powered by compressed air from a compressor. Below is a diagram (in section) on which you can see the design of the device.

The pneumatic spray gun has the following elements in its design (see diagram above).

1. spray head together with the nozzle (nozzle). The nozzle in the spray gun and the air cap are removable elements. They may have different outlet diameters, which are selected in accordance with the viscosity of the composition intended for spraying.
2. paint container. It is made of either plastic or metal, and can be installed both at the top of the tool and at the bottom.
3. Spray gun body. It serves as the basis in which all elements of the device are installed.
4. Locking screw. Regulates the intensity of the ink supply by limiting or increasing the mobility of the locking needle. Some gun models have an air regulator.
5. Lever. Designed to comfortably hold the tool in your hand.
6. Pad. Acts as a seal in the mechanism that moves the needle.
7. Trigger. Sets the locking needle in motion.
8. Locking needle. Opens or closes the nozzle opening.

The operation of the pneumatic spray gun is as follows. When the trigger is slightly pressed, the air valve opens, and air begins to flow through a separate channel into the air cap. When the lever is pressed further, the needle moves back, opening the nozzle through which the paint begins to flow. The paint, mixing with the air flow in the air head, is crushed into small particles, forming an aerosol torch.

For convenient work with the paint sprayer, use a special wall holder.

Also widely used by painters stand for spray gun which can be easily made by hand.

The nuances of the design of paint sprayers with different types of tank

Spray gun device with top tank, as well as the principle of its operation, was discussed above. The only thing that needs to be clarified is the way the paintwork is fed into the tool body. Since the ink tank is located at the top of the appliance, it flows down to the shut-off needle in a natural way, due to the force of attraction.

Spray gun device with bottom tank differs only in the location of the latter. The paint is taken from it due to the rarefaction created by the air flow inside the device. In the future, the operation of the paint sprayer does not differ from the operation of the device with the top location of the tank.

In addition, not so long ago on the market for equipment for applying coatings appeared vacuum tanks. They are successfully used instead of standard paint spray tanks. The vacuum tank is a rigid glass-flask with a hole at the bottom, into which a soft glass with a lid is inserted. The flask has a scale on which it is convenient to determine the amount of paint.

The advantage of vacuum tanks is that they allow the spray gun to work in any position. Regardless of whether the device is turned upside down or upside down, the dye still enters the gun due to the vacuum formed in the soft glass. In this case, the glass is deformed, and the paint is squeezed out of it completely.

Setting the parameters of the spray gun before work

If you look at the body of a modern paint sprayer, you can see 2 or 3 adjustment screws. The first regulator can be located either on the top or on the side of the body, as, for example, on SATA spray guns (see figure below). He is responsible for the shape and size of the aerosol torch.

The second screw allows you to adjust the range of movement of the needle, which determines the amount of paint supplied to the nozzle. Some models of paint sprayers have a third regulator. With it, you can control the air supply to the instrument.

Setting up the spray gun means correct installation material-air balance. By setting the optimal ratio, you can achieve the ideal shape of the aerosol torch, which will contribute to uniform spraying of the composition onto the treated surface.

Gun inlet pressure setting

Important! The inlet pressure parameter is indicated by the manufacturer in those. documentation for the device and is standardized.

Setting the inlet pressure should ideally be done with a regulator, with a built-in pressure gauge, which is connected to the handle of the instrument. This is explained by the fact that pressure losses in the line can reach up to 1 bar and above. The longer the duct, and the more bends on it, the greater the pressure loss. This parameter is also affected installed filters and moisture separators.

With regulator and pressure gauge

Adjusting the spray gun with the upper tank with the installed regulator and pressure gauge is not difficult:

• first unscrew the adjusting screw (1) as much as possible (see the figure below), which is responsible for the air supply;

• further, the regulator of the shape and size of the torch (2) is unscrewed;
• after unscrewing the screws, press the trigger (3), after which the air supply will begin;
• at the last stage, you need to set the value on the pressure gauge (4), corresponding to the recommended one, by turning the pressure regulator.

With electronic pressure gauge

Some "advanced" models of paint sprayers have a built-in electronic pressure gauge.

It is even easier to adjust the spray gun with a built-in electronic pressure gauge (see figure below).

1. Open the flame regulator as far as possible.
2. Pull the trigger.
3. Guided by the readings of the manometer, turn the air regulator until the pressure level at the inlet to the device reaches the recommended values.

With pressure gauge without regulator

In the case when there is a pressure gauge without a regulator on the handle of the spray gun, then the spray gun can be correctly adjusted as follows (see figure below).

Without pressure gauge

If the paint sprayer is not equipped with a pressure gauge, then you can make a rough, approximate adjustment of the device with compressor gearbox, taking into account pressure losses in the line.

Advice! Before setting up the tool, it should be borne in mind that the filter, if it is serviceable and not clogged, reduces the pressure by 0.3-0.5 atm., Not to mention a clogged element. In addition, approximately 0.6 atm. “lost” in the air hose if it has inner diameter 9 mm and length 10 m.

Adjust the spray gun for painting, if it does not have measuring instrument, you can use the following method (see figure below).

If the spray gun is from an unknown manufacturer

Sometimes situations arise when there is no instruction for the device, or it is impossible to determine its manufacturer in order to find out what pressure is needed for the spray gun. The inlet pressure required for such an unknown tool can only be known by experience.

1. First of all, you should choose Coatings of standard viscosity and pour it into a jar.
2. Next, you need to unscrew all the regulators on the tool and use the adjustment screw on the pressure gauge to “experiment” with the pressure. It is required to achieve such a value at which a uniform imprint of the torch appears on the painted surface. In this case, the tool should be kept at a distance of 15 cm from the surface prepared for the test.
3. Upon reaching the desired result, fix the value of the inlet pressure. This will be the working pressure for this device.

Important! You should be aware that most cheap, unknown origin spray guns require increased air consumption for normal operation, more than 200 liters min. Accordingly, not every compressor will be able to provide such a tool. necessary quantity compressed air, which will affect the staining result.

spray jet size

It is no secret that the effectiveness of coating with a paint sprayer largely depends on the state of the torch. The larger its size and the higher the density of the aerosol, the more evenly the coating is applied to the surface with a small number of passes. But in some cases it is necessary to set a small size of the flame, for example, if you want to coat the small parts or paint in hard-to-reach places.

Torch size is easily adjustable: by turning the screw towards the “+” sign, the width of the torch increases, and, conversely, when the regulator is moved towards the “-” sign, the spray area decreases.

Advice! In most cases, this adjustment screw should be in the maximum open position.

Paint supply

When carrying out standard repairs, applying various coatings and painting bodies, it is recommended to open the material flow regulator completely. Usually this 3-4 turns of the adjusting screw. In this case, the nozzle should completely come off after pressing the trigger.

An important role in setting up the paint sprayer is played by the diameter of the nozzle. It is selected according to the density of the composition that will be used for spraying. Below is a table to help you quickly determine what nozzle size you need for different coatings.

The main malfunctions of the spray gun

In spite of simple design, the spray gun is still prone to breakage. Frequent malfunctions of the spray gun can be counted on the fingers.

The gun does not paint

This happens in the following situations.

1. The air pressure in the system is extremely low. The compressor must be adjusted to correct the problem.
2. The ink supply is interrupted due to a clogged needle and nozzle. It is necessary to disassemble the spray gun and clean the listed items.
3. Damaged needle or nozzle. Parts need to be replaced.

Paint sprayer spits

The reason that the spray gun spits can be several malfunctions.

1. Air cap loose. It is required to fasten the part well.
2. The viscosity of the paint does not match the air pressure. It is necessary to achieve an acceptable pressure-viscosity ratio.
3. The paint is too thick. It is necessary to prepare a paint of less density.
4. The breather on the dye bottle is clogged. It is necessary to remove the plug and clean the hole in it.
5. The pressure in the receiver has dropped below normal. It is required in the compressor settings to set the lower pressure threshold corresponding to the performance of the spray gun.

The torch moves to the side

If the spray paint spray is moving away from the gun, then the reasons for this may be the following.

1. Clogged side holes of the air cap. You need to remove the head and clean it.
2. Damage to the side holes of the air cap. The damaged part must be replaced.

Torch spot asymmetry

AT this case, the problem may be caused by the following malfunctions.

1. Nozzle clogged. Repair of the spray gun in this case consists in removing the nozzle and cleaning its hole.
2. Nozzle damage. Part replacement required.
3. Clogging of the air cap, namely, its central hole. Remove the air cap, rinse and clean it.
4. Damage to the center hole of the air cap. This part needs to be replaced.

Construction and painting tools are gradually being improved. The usual brush and roller pushes the spray gun, allowing for a short time color evenly large areas. The device is easy to use, but, like any equipment, sometimes it fails, ceases to perform its functions. What to do if the spray gun does not spray paint properly? Why, instead of a uniform ejection of paint, do “spit” fly out of the nozzle or just blow air?

Varieties of spray guns

To deal with these issues, you need to decide on the types of devices. There are two types of spray guns.

Manual (mechanical)

Works for compressed air. Air is forced into the ink gun manually using a piston pump.

They can be issued:

• with the upper location of the tank, when the dye enters the nozzle under the action of gravity and its supply is regulated by changing the air pressure;
• with a lower tank, when the container is attached from below, the solution is then injected into the nozzle using compressed air.

Airless

Also called electric. Sprays the dye with a built-in pump.

Both of these varieties are very different from each other, and with outwardly identical malfunctions, the repair of a manual spray gun will be very different from the repair of an electric spray gun.

What is required for repair

Regardless of the principle of operation of the dyeing mechanism, before proceeding with the diagnosis and troubleshooting, it is necessary to prepare the following tools and spare parts:

• kit wrenches various sizes;
• pliers;
• screwdriver
• repair kit and other sets of spare parts.

A spare parts store for repair and construction equipment will be able to offer several options for repair kits for troubleshooting spray guns. It could be:

1. Standard repair kit consisting of several bolts and rubber seals(it is better to stock up on such repair kits in advance due to the fact that the seals are under the influence coloring matter quickly fall into disrepair).
2. Specialized kit. The kit includes spare parts for spray guns, necessary to fix a specific problem or replace a failed part.

Malfunctions and how to fix them yourself

With your own hands, using a set of improvised tools, you can fix most problems with spray guns by simply cleaning the nozzle or installing replacement parts instead of those that have become unusable.

Handheld instrument

Hand sprayers may experience the following problems:

1. The coloring mixture begins to boil in the tank, but is not fed to the nozzle. This can happen if the suction valve is clogged. In this case, you can disassemble the unit with your own hands, rinse, clean the valve, and install it in place after cleaning. Or install a new valve from a set of replacement parts.
2. Ink is supplied but not ejected from the nozzle. There can be two reasons for this:
   • The paint has large particles that have clogged the needle and nozzle. To fix this problem, you can clean the parts or install new parts, and grind the coloring solution on a paint grinder.
   • The filter for the spray gun is out of order. To fix this malfunction with your own hands, you need to remove the damaged filter, and install a new one in its place.

1. The suction valve rises under pressure, but the paint from the tank does not come out, the unit does not spray the solution. This occurs because the suction valve is not seated tightly in its seat due to a clogged filter. To eliminate the malfunction, it is necessary to clean or install a replacement valve and filter.
2. Paint under pressure is not supplied to the nozzle, it overflows through the pump cylinder. This indicates wear of the stuffing box packing of the pump rod. Depending on the condition of the packing, either tighten the fastening nut or install a new packing.
3. Weak pressure of the coloring solution with stable operation of the pump in a unit with a lower tank. The reasons may be:
   • A small amount of material left in the lower container when the suction hose draws in air at a strong inclination and supplies the air-color mixture to the nozzle. There is no need for repair, you just need to add material to the tank.
   • The opening of the tank through which outside air enters is clogged. Then it is necessary to clean not only the air supply hole, but also to additionally clean the pump hoses.

1. The pump has stopped sucking paint. The reason for this can only be a pump cuff that has lost its qualities. It can be softened in oil (if it is dry) or a replacement one can be installed (if it is worn out).
2. The spray gun spits uneven jets of paint. This occurs when the nozzle for the spray gun has an outlet that is too large (more than 0.7 mm) due to a washer that has become unusable. To correct the problem, the washer must be replaced using a repair kit.
3. Paint is leaking from the faucet. There can be two reasons for the failure:
   • The faucet is badly lapped. It is not difficult to fix this problem with your own hands - just grind the tap with tools.
   • Weakening of the spring on the valve. It must be tightened or replaced using necessary tools from the repair kit.

electrical appliance

On electric spray guns, unlike manual ones, not all problems that have arisen can be fixed by hand.

To repair some of them, the services of an electrician will be required.

With your own hands, you can eliminate the following problems:

1. The dye intake from the tank has stopped. As with a manual spray gun, the suction valve must be cleaned to correct this problem.
2. The solution is not supplied from the tank to the nozzle. The needle, nozzle, and filter on the suction hose must be cleaned or replaced to restore dye flow. Spare parts can be purchased separately or you can buy a ready-made repair kit.
3. The pump does not supply the ink mixture to the nozzle, sometimes due to incorrectly adjusted air pressure or ink supply, after adjusting these parameters, the device starts to ink normally.
4. Excessive "bubble" of material in the canister can be caused by air being trapped in the canister due to a malfunction or paint head failure. With the help of a set of spare parts, it must either be properly installed or replaced.
5. In the tank, when the pump is running, an extraneous knock is heard, which can be caused by a foreign object that has got there or a metal piece that has broken off from a moving part (for example, a tooth has broken off from a gear). The container will have to be cleaned, and the object that caused extraneous noise should be carefully examined. If this is not a part of the mechanism, then you can put the tank back in place, fill in the dye and continue working. But if you suspect that a part of the moving mechanism has broken off, it is better to contact the services of a master for inspection and preventive repair of the spray gun, and not try to fix the breakdown with your own hands.

To eliminate the following problems in the operation of the electric spray gun, you will need to contact the services of an electrical equipment repairman:

1. When the device is turned on, no noise is heard from the operation of the electric motor. This happens if the fuses are blown or the switch is broken.
2. When touching a unit connected to the network, current discharges are felt. Using the device in this case is life-threatening, it must be immediately handed over for repair. The cause of the breakdown, most likely, is the short circuit of the parts responsible for conducting current.
3. With strong heating of the body of the apparatus during operation, timely repair will prevent wear of the parts of the electric motor due to insufficient lubrication between them.
4. The unit is working, but the pressure gauge does not show that there is pressure. The cause may be a malfunction of the electric pump or pressure gauge.

A spray gun is a complex tool that requires careful handling. In order for it to work for a long time without breakdowns, the following rules for caring for the device must be observed:

1. Clean immediately after finishing painting work. For this purpose, the tank of the apparatus, after removing the coloring material, is filled with a solvent having a composition similar to the dye used, and after that the device is turned on and used on an unnecessary surface. The pressurized contents of the tank will good cleaning all valves and hoses.
2. Never use a solvent that could cause a "chemical conflict" with the staining solution being used. Coagulated paint residues can damage the mechanism.
3. After rinsing, the device should be thoroughly blown out, and the container should be left open for a short time to evaporate the remaining solvent.
4. The paint sprayer with the coloring composition inside can only be left for a short time, but before that, take the following measures to prevent the composition from drying out: tighten the needle regulator all the way and tightly close the hole from air entering the tank.
5. Before refueling to remove condensate or accumulated dust, the spray gun must be thoroughly blown out.

Most spray gun failures can be prevented by proper use of the unit. But if there are breakdowns, many of them can be fixed on your own using repair kits, which include various sets of spare parts and accessories. timely Maintenance and proper care will help the tool to serve its owner for many years.

The spray gun is used for painting any surfaces. The paint lays down evenly, its consumption is minimal, it takes little time to work. But in order for the quality of the painted surface to be excellent, and the paint itself to be consumed as little as possible, it is necessary to adjust the spray gun. What exactly is this being done for? For each type of coloring matter, the conditions for supplying the mixture are different. Pressure, paint torch can be completely different. Therefore, before using the equipment, it is necessary to properly adjust the spray gun, test its suitability for work. After that, you can safely start staining, it will not take much time.

Basic rules for adjusting the spray gun

Before starting work, be sure to adjust the equipment. Otherwise, it will malfunction. If you do not make adjustments, then the ink consumption will be too large, the quality will decrease. To perform the adjustment, special adjusting screws are used. They allow you to set the required size of the torch for painting, the shape of the spray pattern. For adjustment, a special test is used, i.e. applying a coloring composition to a sheet of paper or drywall.

The through hole and the amount of paint to be sprayed are pre-selected. It is necessary to choose at what distance it is necessary to keep the equipment, how to dilute the composition so that it is not too liquid or thick. Spray pressure can be set. It all depends on what kind of paint is used for the job. Typically, the working pressure is 3-5 bar, but individual formulations may have their own requirements. During this adjustment, you can change the shape of the cone.

In order for paint consumption to be economical, it is necessary to determine not only the supply, but also the degree of its dilution. Only trial staining is used, since other methods can be used to obtain exact value will not work. It is necessary to carefully examine the paint stain, its quality, intensity. This will allow, spending only half an hour, to accurately dilute the paint for use, determine the distance and other indicators. If the paint is too liquid, then the stain is obtained with streaks, not of high quality. To avoid such situations, you must first dilute a small amount of paint, and not all at once. In this case, it will be possible to eliminate unnecessary costs.

Health tests

In order to properly adjust the paint sprayer, it is necessary to carry out a series of tests that are not very difficult. This will increase productivity and reduce paint consumption to a minimum.

These tests include:

• checking the quality of paint spraying;
• checking for a torch imprint, its correctness;
• checking the uniformity of paint distribution.

The spray quality test is simple. It is necessary to apply a strip of paint with a spray gun on a piece of drywall. After that, you can evaluate the size of the drops, the uniformity of the application of the strip. The band itself will be most intense in the center, and will become less uniform towards the edges.

The shape of the imprint for a torch is defined differently. It is necessary to hold the spray gun on at a distance of 15-20 cm from the surface for a second. If the ink impression is even and perfectly defined, then the equipment is adjusted properly. If there are numerous splashes around, then the pressure is too high, it must be reduced. If the spot is uneven, then the pressure is insufficient or the holes are clogged.

Even distribution of paint is also important to avoid streaks during application. If they are, then most likely the pressure is insufficient. The spray gun during testing is configured as follows:

1. It is necessary to make sure that the nozzle, all holes are free of paint, correspond to the type of coloring composition.
2. After that, a sheet or piece of drywall is fixed in a vertical position (a piece of 50 * 50 cm is enough).
3. The pressure is set as required by the instructions.
4. After that, a test strip is stained so that it can be evaluated and adjusted.
5. A vertical and horizontal stripe is carried out to determine the uniformity of the applied paint, the quality of the surface.

After the assessment, the following conclusions are made:

1. The torch is properly adjusted if the spot is symmetrical and even. The height and width of the resulting spot must fully comply with those stated in the instructions. The paint is distributed in an even layer without spatter.
2. The torch gives stripes in the form of a crescent. This indicates that the nozzle is dirty or damaged, as well as the center hole or side holes of the special air cap.
3. The torch takes on the shape of a figure-eight when turned on. This means that the paint is liquid or is fed high pressure, it should be lowered.
4. Intermittent torch. This is a sign that there is little paint left in the tank, the level must be checked. Air could get into the channels that supply the paint. In this case, they need to be cleaned. Tank vents are dirty and need to be cleaned.
5. The torch is delivered in the form of a drop. In this case, the spray gun is held incorrectly relative to the surface. The nozzle may also be dirty.
6. The torch is issued in the form of an ellipse. In this case, thick paint is used or the feed is high at too low a working pressure.

Possible problems and solutions

The spray gun is a simple equipment, but such a tool may break down or start to work incorrectly. There are few such cases, but you need to be aware of how you can fix the equipment with your own hands. Among the most common problems when working with a spray gun are:

1. The air cap may be damaged, which can be seen from its center hole. It is best to immediately replace the entire broken assembly if it cannot be cleaned. But before such a replacement, it is better to try to clean the hole, for this a thin needle is used. When, after cleaning, the nozzle still does not deliver a normal stream of paint, the assembly is replaced. This is not so difficult to do, you only need to purchase a head suitable for a particular spray gun, you can find it at any hardware store.
2. Defects were found at the side opening of the head. Most often this is due to the fact that it is clogged with paint if the spray gun is not washed after use. It is easy to clean them, for this a needle is used.
3. The nut on the guide bushing may be overtightened. If this happens, then you need to carefully clean the air valve stem, then shift the location of the torch, slightly loosen the position of the nut. The cleaning needle is carefully inserted into the head of the spray gun, the stem is replaced if necessary, but it can also be cleaned.
4. The stroke of the ink lever is too tight. There can be several reasons for this problem, but most often it is a dirty air valve. It needs to be cleaned properly. If this measure does not work, then you should check the tension of the nut, it may be too tight. Among possible solutions- replacing the stem, cleaning the needle, complete replacement paint head.

During adjustment, the torch is set to a position directed along the axis of the device.

In this case, it may well be that the air cap, side holes are clogged. It is necessary to inspect them, and then, if necessary, thoroughly clean or completely replace the pneumatic head of the equipment.
