What can be cooked from squid: quick and tasty

Over time, sinks have become more and more widespread in the domestic markets. high pressure mainly used for cleaning cars. Using such a device, you can wash both the body part and the bottom and engine compartment... The undoubted advantage of this device is that a precisely directed jet is used to remove dirt from the surface of the car without the use of a powerful water pump. A very profitable idea is a high pressure washer with your own hands, which allows you to significantly save money spent on periodic washing of the car. If we take into account the domestic weather conditions, when at any time of the year there is dirt on the roads in any of the states of aggregation, then such a wash will pay off very quickly.

The easiest way to do your own wash is to use an air compressor.

Basic principles of creating a sink

The main functional element of the sink is a pump that meets a number of requirements. So, it should show high functional performance per unit of time and work normally at a pressure of about 100-200 bar. Many electrically driven plunger pumps have these characteristics. When choosing a pump for your future wash, special attention should be paid to the material that became the basis for its working part. The best option if ceramic or durable metal is used for the pump pistons. The best option for making a cylinder head is brass. Robust components guarantee a long service life.

The most profitable would be to purchase a pump with a working capacity of about fifteen liters per minute and a pressure of up to two hundred bar.

It turns out that such a pump in normal operation will operate at 80-90% of its maximum capacity.

Selection of parts for washing

When choosing an electric motor, you should pay attention to models that have a power supply of about 220 or 308 volts. In the event that the pressure washer will be used at home, it is advisable to use a single-phase 220 volt connection, since it will not entail additional costs and meets all safety requirements. To ensure optimal starting of certain motors, it is advisable to use additional capacitor banks. So, the pump performance directly depends on the number of engine revolutions: the higher their frequency, the greater the performance.

But it should be borne in mind that working in this mode can negatively affect its resources. Do not give preference to models that are too fast. The maximum permissible rotational speed in this case is up to two thousand revolutions with a power of two or three kilowatts.

A high-pressure washer of a certain design allows you to provide the required pump performance when using a single-stage gearbox operating with a V-belt drive. Their gear ratio depends on the parameters of the pulleys (driven and driving). An equally important role in the activity of gearboxes is played by the characteristics of the distance between the axes of rotation.

To ensure the fixation of the pump and the motor, a clutch is usually used. Most suitable option- a soft coupling capable of compensating for the minimum axial misalignment of the shafts and acting as a safety element in the event of a gearbox or pump jamming.

Very important structural element any sink is a container for storing water. In order to ensure maximum pump performance, it is necessary to use a certain volume of liquid. For this, it is possible to use a special fluid tank capable of making up from the water supply network. It is imperative to install a filter element at the outlet from the tank (this can be an ordinary small network), designed to clean the liquid from dirt particles and prevent blockages from entering the pump. To enhance the cleaning effect, you can add a special or regular detergent to the liquid.

A do-it-yourself car wash should have a pump performance regulator in its design. Typically, this device has a connection with an automatic unloader valve, capable of redirecting the liquid back to the tank in an emergency, so that a harmful load is not created on the pump.

In order to fix all the structural elements of the sink, a special frame is used. For its construction, hollow curved pipes can be used. To ensure ease of use, you can fix a pair of small support wheels at the bottom of it and make an emphasis to give the structure stability during use. One end of the frame can be equipped with a special handle for transporting the sink around the yard or garage.

The main structural element of a homemade sink is a water tank. To ensure maximum pump performance, a certain volume of fluid must be used.

One of the most important elements that make up a hand-made sink are high-pressure hoses. A standard, not too thick, reinforced rubber or plastic hose can act as a sleeve. It should be borne in mind that all structural connections of the hoses must be made in compliance with the tightness conditions, on the one hand, and not be afraid of corrosion and easily disassembled, on the other. To equip the fasteners, you can use fittings or threaded bushings made of hard aluminum alloys or brass. For this purpose, it is possible to install bayonets.

When constructing a sink with your own hands, you must also pick up a gun equipped with a nozzle. Thanks to its shape, an imitation of the shape of the working jet is obtained. Actually, appearance it resembles a pistol used at gas stations. In order to start supplying water from the nozzle, press the handle. This is an undoubted advantage, as it saves a large amount of water: the liquid is supplied only when it is needed, by pressing the pistol grip. Execute stop valve do it yourself quite problematic, the simplest and most reliable option would be to purchase a ready-made tip.

A high pressure pump from a car washer is perfect as a compressor for a car wash.

When installing a pressure washer, you need to take care of creating a ground. For this purpose, a three-core, double-insulated flexible wire and a plug supplemented with a grounding terminal are often used. It should be borne in mind that the power outlet also needs a reliable grounding using a circuit.

Periodically, it is necessary to inspect all connections and fasteners and tighten them if necessary. The filter element of the tank should be cleaned of accumulated debris on a regular basis.

It is undesirable to use too often a jet of water with a strong pressure - this will overload the injection pump and damage the paintwork of the car. It is recommended to apply pressure that can contactlessly rid the machine of the main layer of dirt on the surface to be treated, and manually remove the remaining dirt with a brush.

How the pressure washer works

Thanks to the devices operating at high pressures in the range of 120-150 bar, dirt can be removed from almost any surface. You should be prepared for the fact that a small layer of plaque will still remain after such treatment.

Manual homemade car wash.

Any sink must have a device that regulates the nozzle. By adjusting the position of the nozzle, you can change the pressure or the shape of the jet. The nozzle can be equipped with foam generators and additional mud blades.

If you wish, you can construct a sink with your own hands that can be fed not only directly from the water supply system, but also from a special reservoir - for example, a barrel of water. To improve the pressure in the sink, you can put the barrel on a slight elevation.

In the event of a power outage or the use of a sink far from outlets, you can equip the device not only with a water tank, but also with a powerful battery.

The undoubted advantage of sinks of this type is a large water saving, in contrast to manual sinks.

Washing device

Car wash device.

There must be an engine inside the pressure washer that causes the remaining parts to rotate and open - a valve, washer or sprayer. The result of its work is the unwinding of the washer and the movement of water along the sprayer according to the forward-return trajectory, as a result of which the water enters the sprayer valve. The result of the action of many mechanisms is the formation of a powerful pressure and water supply.

It is advisable to choose the body for the sink made of impact-resistant plastic. The same requirements apply to the hose connected to the atomizer, as it will have to interact with a strong water pressure.

No matter how durable the materials of which the sink is made, it is highly discouraged to use it for more than two hours in a row. Too long operating cycle can lead to rapid wear of the constituent parts and shorten the service life of the device several times.

If you equip the sink with additional attachments, it will be able to perform the functions of household appliances. When using additional attachments, the sink can be used both for washing a car and for cleaning roofs, facades and floors.

Main parts of the pressure washer

A DIY sink consists of the following elements:

Diagram of a homemade mini-washer.

durable, wear-resistant housing;
an engine powered by gasoline or electricity;
a pump operating at high pressure;
containers for water and detergents;
additional attachments;
water filters;
hoses.

The principle of operation of a homemade sink is extremely simple. From the water supply or special capacity after connecting, water enters the sink container and is pumped out using a pump. At maximum load, the washer operates at a pressure of about 160 bar. For comparison, a stream of water from a conventional tap is supplied under a pressure of five bar.

Homemade car wash.

The next step is to supply water through a hose to the nozzle gun. It is advisable to equip the gun with a special nozzle that allows you to change the nature of the water flow - from a concentrated jet to spraying. The nature of the water supply should be determined based on how the surface will be cleaned. For example, to cover large area(veranda area or car body) the best option there will be a fan jet. In order to remove fragments of stubborn dirt, it is advisable to use the point version of the water supply.

Additional options include a rotating nozzle, rotating brush and much more. The main advantage of using nozzles is non-contact cleaning of the surface, which significantly reduces the risk of damage to the paintwork of the car body or the decorative surface of the facade tiles.

When choosing parts for your sink, do not chase after maximum power. A household sink can function normally at an operating pressure of 100 bar. Moreover, for a person who has not previously encountered such a technique, it will be problematic to control a high pressure washer.

Additional washing functions

Washing power diagram.

When designing a sink with your own hands, you can provide for another additional function - water heating. It will be a good option when using the sink during the cold season. Heated water copes much better with old dirt.

Water heating can be ensured by installing a special burner inside the housing. The installation of additional elements affects the dimensions of the entire structure - if there is a desire to equip the sink with an additional function, it is necessary to choose a slightly larger body for this.

Washers that are not designed for hot water are more compact and maneuverable to use.

In order to make a high pressure washer with your own hands, you should think about choosing a power source for it. If there are no problems with the electricity supply, you can design an electric sink. If the car wash needs to be mobile, it is better to run it on gasoline.

It is worth thinking about the mobility of the structure - the sink can be both stationary and mobile. Mobile car washes are convenient to use for cleaning hard-to-reach places of the car body. For their construction, a longer hose and several wheels are used. Stationary structures are more suitable for use on an industrial scale and can be connected exclusively to the water supply.

Some craftsmen have come up with a way of attaching a water stop system to the sink - when the user stops holding the gun handle, the water supply automatically stops. This innovation saves a lot of fluid.

When buying parts for a sink, do not save money - cheap models will not last long. It is very important not only to extend the life of the sink, but also to select high-quality water filters to keep the surfaces to be cleaned in proper shape. There is a high probability that abrasive particles can enter the pump with water, which can lead to destruction of the pump pump. The most profitable option is reusable filters.

Many take on the creation of a car wash with their own hands in order to make a profit - a car wash operating at high pressure is capable of serving a considerable stream of cars. Many modern car washes work with just such devices. It is noteworthy that such a car wash can be used both for cleaning cars and for motorcycles, bicycles and accessories.

Step-by-step instructions for creating a sink

The first step is to select the appropriate pump unit. If the sink will be used in a commercial way, it is better to opt for industrial units. Basic requirements: it must be a plunger pump with ceramic pistons. The increase in the service life is accompanied by the presence of a crank mechanism.

An autoloader valve must be connected to the pump. It is produced in two variations. The first type is a closed valve on the pump. After the gun closes, the system relieves pressure and water begins to pump from outlet to inlet. It is advisable not to use such a device for more than three minutes. A valve with a bypass is more convenient to use. When the pressure is released, the liquid through the manifold will flow directly into the container or directly into the sewer - depending on the type of sink connection.

Mini washing post AROS.

There are two ways to connect the motor and pump to each other. If a full shaft motor is available, it can be directly coupled to the pump. In this case, the motor shaft will be located on the front bearing and create additional stress on it. This will be the simplest and most economical option. It should be borne in mind that a hand-made car wash with a similar engine will have a short overhaul period due to high starting loads. A situation may arise when it is not possible to remove the pump shaft from the motor. In order to avoid the development of such situations, it is advisable to install a soft starter in the sink.

Another option for coupling the engine and pump is to use a clutch. The clutch will act as a cushion to cushion the shock that occurs during starting. The clutch acts as a protection against misalignment of the shafts. In order to reduce the starting load, a smooth descent mechanism can be used: thanks to it, the power in the system will increase gradually.

The next step is the sink must be frame-mounted. The following steps are performed sequentially with their own hands - the installation of an electrician, a pistol with a nozzle and a high-pressure hose. It is very important that the pressure washer is installed in accordance with the recommendations of the part manufacturers. It is necessary to strictly adhere to the assembly sequence, take into account the load exerted on the screwed bolts, use anaerobic clamps, and the like.

It is required that the sink is connected to the water supply with a hose, the length of which is at least seven meters. This is the optimal length to smooth out pressure surges in the water supply system. If your hand-made sink will be fed from a water tank (the capacity should not be less than thirty liters), it is advisable to use a hose with check valve... This part is capable of increasing the working pressure.

The household goods market is replenished every day with new products that are designed to make life easier for a person. And here, far from the last place is occupied by a high-pressure washer, which makes it possible to significantly facilitate the process of washing a car, paths, showcases and much more. A powerful jet of water is able to clean dirt even in the most difficult-to-reach places, to cope with old dirt on any surfaces.

But at the same time, it is worth noting the fact that, due to the high cost, not everyone can purchase a device of this type, and therefore some craftsmen make it on their own. But how you can make a high pressure washer with your own hands, we will talk in this article.

The content of the article:

How to make a pressure washer yourself?

Pump and electrical network... For any water supply device, the pump is the basis. And in our case, it must also be powerful enough (from 150 atmospheres).

When choosing a pump, special attention should be paid to the working units, that is, to the material from which these products were made.

If possible, we choose a product with a high-strength metal or ceramic piston. In this case, the block head is recommended to be selected from brass or bronze alloys. This design can last much longer. The resource between repairs is quite high.

A speed of 15 l / min is sufficient for the pump.

It is recommended to choose an electric motor with a voltage of 220 V. Reliable start-up can be provided by an additional capacitor unit. The higher rpm also provides greater productivity. But at the same time, a pump that is too high-speed at maximum operating speed is subject to intense wear.

The best option is a consumer of 2-3 kW and rotation up to 2000 rpm.

A homemade high pressure washer, in order to preserve important nodes in the chain, it must also have safety elements. This link is the coupling that connects the pump to the engine.

If possible, we install such a coupling that could compensate for small axial misalignments between the shafts.

It is also possible to install a belt drive with one stage, which will balance the speed and load between the engine and the pump.

The subordinate number is selected based on the required parameters for the frequency of rotation.

Tank and capacity regulator... The mini-washer also needs a water container. In this case, you can use a simple tank, which, if necessary, can also be powered from a constant source of water (a well or a water tap).

To exclude the possibility of getting various debris, it is recommended to install filters of coarse and medium cleaning at the entrance to the tank.

We also add shampoo or other approved car cosmetics to the main water tank. In this case, the washing process will be more efficient.

As a rule, the pump has a capacity regulator combined with an unloading auto-valve, which redirects the unused pressure back to the tank, reducing the load on the pump.

External elements... We fix all the elements on a frame, which can be made of shaped or round curved pipes. For the convenience of transporting the unit, a pair of wheels can also be attached to the lower pipes. In addition, we also install stops for fixing and a handle.

You can see how such a mini sink will look in the photo.

For a high pressure hose, you can use a plastic or rubberized reinforced hose. It is imperative to ensure the tightness of the joints using high-quality clamps or hydraulic sealing.

The unions and valves used must be made of low-corrosive alloys: brass or bronze.

The water supply will be made through the gun with the nozzle installed in it. Visually, it looks like a pistol from a gas station. A stream of water will be formed after pressing the button, which in turn will also save working fluid with consumable additives. You can buy a pistol of this type at almost any hardware store.

Periodically inspect the connecting nodes, and if necessary wrench tighten the screw connections.
In order not to reduce the throughput of a homemade mini-sink, before each connection, we inspect the filters installed in the device.
To avoid accidents during operation, it is imperative that we ground the electrical part. Therefore, the plug used must be with a grounding terminal, and the cable is copper, three-wire.

How to make a foam generator with your own hands?

You can also make a foam generator at home. Of course, in terms of functionality, such a device will lag behind its counterpart, but in everyday life it is difficult to overestimate its benefit.

From the tools we need:

Set of wrenches;
Roulette;
Bulgarian;
Pliers;

1) .We use an inch pipe with a length of about a meter. We clog the front part of the product with a polyethylene washcloth, the purpose of which will be to form foam.

2) ... We make a plug for one of the edges of the pipe, and a special tee is also screwed in here. After that, we connect the tap under the foam generator to the opening at the entrance.

3) ... On the other side of the branch pipe, we install a tap, through which compressed air from a car compressor will be supplied.

4) ... We combine the second pipe outlet through a special fitting with a foam hose. To prevent the sponge from getting into the tube, we also install a special filter. In this case, the filter element can have large sections.

A diagram of a foam generator of this type is presented below.

Please note that the density of the foam produced depends on the length of the tube and the density of its filling with a washcloth.

Any container that can withstand the compressor pressure is suitable as a liquid tank.

How to properly wash your car with a car wash?

Hand washing is the so-called easy way to clean the car from dirt. But as practice shows, in this way it is possible to partially clean the surface of dirt. The use of special technical means- car washes that supply high pressure detergent and water.

Thus, you can not only clean the dirt, but also a layer of oxides and synthetic resins, which during the ride are deeply "rubbed" into the paintwork.

Knock off dirt from the sprayer of the car wash with a stream of water in different directions.
Apply a weak foam concentrate to the surface of the body under low pressure, which will effectively wash off the first two layers of dirt.
Rinse the surface of the vehicle with plenty of water.
Apply the main detergent under high pressure, and this must be done from the bottom up. Leave the applied product for 3-5 minutes. At this time, you can rinse wheel disks, suspension elements, bottom.
Rinse the surface of the vehicle with plenty of water. Remove its remains with a squeegee and special napkins. Wipe the car dry, while not ignoring the inner surfaces (sills, doorways).

It is not recommended to wash the car until its body has cooled down. . The consequence of contact of water with a hot body can be the occurrence of a corrosion process.
If the surface of the car has ever been repaired with putty, you should not wash the car under too high pressure.
It is recommended to wash the car with special detergents no more than 1-2 times a month, since such detergents contain substances that can negatively affect the paintwork.
Whenever possible, use those detergents which are recommended by the manufacturer, as they are best suited to the paintwork of the car.

Do you know that if your car is more accustomed to a high-pressure car wash, with your own hands you can also provide it with such a luxury without special stations?

Features of high pressure car wash

Why are most of the special stations equipped with this type of sink? This is due, first of all, to the fact that with the help of this device it is possible to wash the body, bottom, suspension, without making any special efforts. The main positive feature of a high pressure car wash is that a directed jet of liquid easily and effectively removes dirt from the surface of the object. This jet arises from the operation of a high-performance pump, and forms its special tip.

Such a device will be useful not only for, but also for various household needs. So the intention to acquire your own system will also solve many everyday tasks, especially if you have a plot with a spacious house at your disposal. At least the washing of street communications and paths will be many times faster. There are many stores that sell this type of product, but it is much more pleasant to make a high pressure car wash with your own hands. Moreover, this process is not particularly difficult.

Do-it-yourself high-pressure car wash - basic elements

The first thing to do is purchase all the parts you need to assemble the device. The most important and expensive part of a car wash is the pump. It should be of high performance. In addition, such a pump must develop a pressure of up to 100-200 bar. When choosing this part of the system, it is very important to pay attention to what materials it is made of. Most the best option The working part of the pump should look like this: the pistons are made of strong metals or durable ceramics, the block heads are cast from brass, and a large support area must be provided for the liners of the crank mechanism.

Sometimes, to save money, a car wash is assembled from a compressor, such a system is made, of course, faster with our own hands, and the compressor in this situation acts as a water pump.

One more important detail is the electric motor. For a home car wash, it is best to use a 220-watt electric motor, that is, a single-phase one. This type of connection is safe and saves a lot cash... Some car wash designs include capacitors and a single-stage gearbox. These elements can make the device easier to use as well as extend the life of the device, but they are not required.

We collect additional elements for a car wash

When creating a car wash with your own hands, you will also need a clutch. This element connects the pump and the electric motor. For high pressure washers, the best option would be to use a "soft" coupling, since it is able to compensate for the misalignment of the shafts along the axis. In addition, this type of clutch plays the role of a safety device in case the pump or gearbox gets jammed.

An important element in the design is the water tank. Indeed, in order for the pump to work uniformly and uninterruptedly, it must receive a certain volume of water. Most often, a tank is used as a container, which is connected to the water supply network. At the outlet in the tank, a special fine mesh is installed, which serves as a filter. This is to prevent dirt from entering the pump and interfering with its operation. The washing effect can be significantly improved by adding detergent to the tank.

A necessary element is also a pump capacity regulator. In most cases, the regulator comes complete with automatic valve unloading. This device is necessary in order to redirect water back into the tank in case of a need arises, in order to avoid overloading the pump. Also, in the process of creating a car wash with your own hands, a frame is used as the basis for all parts. In addition to it, high-pressure hoses are needed for operation, as well as a gun with a nozzle. After all the elements are fixed on the frame and connected to each other, the work on the car wash can be considered completed and you can start using this device.

Today, buying a pressure washer is not financially costly. You can find a good household option from 5,000 rubles. The only problem is choosing a good manufacturer. The most demanded in the market are Bosch, Shtil, Karcher and some others. However, there are also many who, for some reason, prefer to assemble a car wash with their own hands, ready-made solutions are fundamentally not satisfied with them. Moreover, in most cases, making such a homemade product is not a rational solution.

On the one hand, a homemade sink will show that your hands are growing from where you need to, but on the other hand, it is easier and perhaps even cheaper to buy ready-made solution... This will eliminate the need to search for information from the compressor or from the high pressure fuel pump from diesel engines to assemble your own washing machine. Plus, you will need to find a pistol (again, you need to buy it separately) and some other important structural elements. With all this, no one guarantees that homemade device will be reliable, and the sink with it will be of high quality. As a hobby option homemade apparatus can be considered, but unlikely as an alternative to a factory wash.

Recently received very high popularity high pressure washers(AVD), most often they are used in car washes. With the help of AED, you can quickly and efficiently wash the car body, engine compartment, such hard-to-reach places as the bottom and wheel arch liners. But the use of such units is not limited to the car: they are successfully used in agriculture, metallurgy, utilities, etc.

The main cleaning principle is a directional high pressure water jet. Coming out of a special nozzle (nozzle), it is able to effectively clean the most severe impurities and remove complex blockages in pipelines.

Therefore, the "heart" of the AED is high pressure (or pump).

Having carefully studied this article, you can easily independently assemble a fairly professional high-pressure apparatus by purchasing components for assembly on our website.

Consider how you can assemble a medium-sized high-pressure apparatus for washing cars, cleaning pipelines with a diameter of up to 150-200 mm, pumping sludge from wells and sedimentation tanks, washing facades, and hydro-sandblasting.

Price pressure washers consists of two main components: a pump (pump) and a drive (, an internal combustion engine, a hydraulic drive). This is the most costly part in creating an AED.

Choice pump(pump) high pressure. We will only touch upon models with a crank mechanism.

You need to rely on three main parameters: working pressure, productivity (water flow) and shaft revolutions. In order to cope with the above tasks, we need a capacity from 900 to 1250 liters per hour and a working pressure from 180 to 250 bar. Low rpm on the pump shaft take priority over high rpm, as this increases the pump life. An important role is played by the width of the connecting rods on the shaft, however, with proper operation (sufficient level and timely oil change, prevention of overheating), this parameter can be neglected.

Electric motor... It is necessary to determine the power of the electric motor (or other drive). Many manufacturers of high pressure pumps willingly publish information about this in the characteristics of their products. For example, let's take a capacity of 900 liters per hour and a working pressure of 200 bar. An approximate calculation, without delving into the exact formulas, will be as follows: the product of capacity (l / min) and pressure (in bar) is divided by 550. We get the power value. The connection of the electric motor to the network is necessary through a contactor or a special starter. All equipment must be grounded.

The most in a simple way the connection between pump and motor is shaft-to-shaft. With this mating method, the motor has only one rear bearing and the pump is bolted to the front motor cover. You can use other types of connections, using a flexible (elastic) coupling and flange, gearbox, belt transmission using pulleys.

On the resulting "monoblock", if desired and possible, you can "hang" pressure, switches "", a thermal valve, a damper, a pressure gauge, a cleaning filter and much more.

Frame.

If the device will be used stationary, then the frame is not necessary. But then you need to find a secure place to mount the electric motor.

If AVD is supposed to be transferred from place to place, then it will be required frame from metal pipes or profile, for mobility, you can equip it with wheels and a stop, as well as handles for easy transportation.

The quantity and quality of the water supplied to the high pressure pump is important.

Storage capacity. The best way to solve this issue is a storage tank, which has an autofill from the water supply network using a conventional float valve. It is necessary that the container is not completely sealed, but excludes the possibility of ingress of dirt or particles into it, so as not to damage the seals or ceramic inserts of the pistons (plungers). To do this, a filter is installed at the inlet to the container and the necessary valve is arranged on top. It is not recommended to add detergent solution directly to the container. For this, it is best to use sprayers, foam ejectors.

Most high pressure pumps are capable of drawing water on their own (self-priming), but you should not place the pump higher than 0.5 meters and use a regular garden hose for supply. For these purposes, you need to purchase a rigid hose (delivery-suction). The inner diameter of the hose for a pump with a capacity of 900 liters per hour must be at least 15 mm with a length of 3-5 meters.

Regular "soft" hoses are only suitable for use directly from a pressure water mains. But do not forget that in such networks there are problems with the water supply necessary for the pump. This can adversely affect pump performance and shorten the life of the internal seals ().

Regulator... When installing a pressure regulator the best way connection will use the bypass channel with its closure in storage capacity... In this case, when you close the gun, water will circulate through the container, and not inside the pump.

High pressure hose or - the length is selected as required, you can use several small hoses and a special connector. So that the hose does not wear out prematurely, because usually in the premises of sinks there are concrete floors without coating, it is worth using a special spiral protection made of polypropylene.

For canal cleaning hoses and (nozzles) are used.

, nozzles, nozzles- everything can be purchased for specific tasks that you set to complete current tasks.

Important Tips:

Pay attention to the screw connections - they must not leak and be securely fastened.

Do not try to unscrew the hose if it is under pressure - turn off AVD and release the pressure!

Clean the filter regularly, even if it is "visually clean".

Do not use gun on / off unnecessarily - frequent firing will wear out the gun regulator and valve!

Mainly for competent use AVD, just read the operating instructions! Your device will serve you for a long time and will require regular replacement of wearing parts in the pump-cuffs, valves, in the pressure regulator and scheduled oil change.
