Using a construction hair dryer. Why is a hair dryer needed and where is it used? What is the difference between household construction tools and professional tools?

An industrial hot air gun, also called a construction hair dryer, is widely used in construction sites and is multifunctional tool. If you want to purchase such a tool, then you need to decide on its use - for what kind of work and in what volumes you plan to use it. You should also be sure to familiarize yourself with its main technical characteristics. Before choosing a construction hair dryer of a certain model, it is worth considering in detail all the types and qualities of this power tool. This is what we will do in this article, in which, together with the website, we will study all the varieties and characteristics of this tool.

How to choose a hair dryer

How to choose a hair dryer: varieties of this tool

There are two types of tools in this class - professional construction hair dryer and household hair dryer. The operating principle of both types is the same, the difference between them is only in the power and outlet air temperature. But the tasks and functions of these electrical appliances are completely different.

An ordinary household hair dryer is used for drying and styling hair, where the output temperature should not exceed 60˚C. The construction hair dryer, which we will talk about in this article, is similar in appearance to it, but this is only externally. The main difference between an industrial hot air gun and a household one is the scope of application of this device and its technical characteristics, the main of which are heating and power.

Thanks to the increased power, in comparison with a household hair dryer (on average 1.5 kW), the outlet temperature of a construction hair dryer can reach up to 750˚C. Structurally, such a tool is an electrical device that includes a heat-resistant housing and is quite powerful. a heating element and a high-speed fan that creates a continuous flow of hot air. Typically, an industrial hair dryer comes with a set of attachments adapted to perform various tasks, which significantly expands the scope of application of this tool, raising it to a level of high versatility.

Commonly used nozzles for hair dryers

As a rule, one or more special attachments are supplied with a construction hairdryer for performing various works. Some of them are specialized and sold separately from the tool, so you need to be prepared for additional purchases.

The most widely used attachments for hair dryers are:

1. Focusing round nozzle. Used for sealing various cracks using welding plastic tape, soldering copper pipes using a non-contact method, repairing boats, skis, and so on.

2. Flat nozzle. Used to remove old paint and, wallpaper, film, as well as for controlled deformation of plastic, polystyrene boards and PVC products.

3. Welded mirror. Used for resistance butt welding of plastic parts - the joined parts reach the welding point, pressed against the welding mirror.

4. Welded nozzle. Its direct purpose is to connect welding cables on a synthetic basis.

5. The wide jet nozzle is a type of flat nozzle and is used to remove paint from large areas.

6. Glass protection nozzle. Special device, intended for surfaces that cannot withstand high temperatures (for example, glass), is used to remove putty, varnish, and paint from them.

7. Slotted or crevice nozzle. Used for welding PVC materials using the cap method.

8. Carved nozzle. Designed for cutting foam plastic in straight and shaped ways.

9. Gearbox attachment. This is an adapter for slotted and carved bits. In addition, it can be used for spot welding.

So, do you need an industrial hair dryer? Let's take another look at what it is capable of, and whether buying it would be a waste of money?

Scope of application of a construction hair dryer

A construction hair dryer, the use of which is quite justified in construction, can be used to remove old coatings of walls, ceilings, doors and windows, and defrost water pipes, controlled deformation (bending), plastics, roofing felt, soldering of awning and polypropylene fabrics. It is possible to use a hair dryer as blowtorch and even for lighting coals in the grill! Briefly, the scope of application of an industrial hair dryer can be described as follows: it can be used wherever local heating of surfaces is required.

One of the main functional features The advantage of a construction hair dryer is that it has a smooth adjustment of the output temperature, which allows you to work with materials that have different melting points. There are models without smooth adjustment, but with several fixed temperature modes. A construction hair dryer with temperature control in this way is inferior in its capabilities to a tool with smooth temperature control.

Construction hair dryer: application

All professional industrial hair dryers have in their arsenal a cold blowing function, which can be useful in many cases. It is better if the construction hair dryer you choose is equipped with a digital electronic display, which greatly simplifies some technological operations, for example, sealing joints with heat-shrinkable tubes. Naturally, the price of such an industrial hair dryer will be much higher. From a safety point of view, it is mandatory to have a protective casing, which, although it makes the device heavier, minimizes the risk of human burns or melting of the workpiece.

How to use a hair dryer photo

Well, in conclusion, I would like to add that the question of how to choose a hair dryer is not purely individual - according to by and large, the difference between this tool lies solely in the temperature of the air heating. And attachments that are fully responsible for its intended use can be purchased separately. First of all, the hot air gun you purchase must be reliable and powerful.

To be honest, I never considered a hair dryer to be a tool that should always be at hand, but one day, when I first saw the possibilities of a good construction hair dryer at work, I stood spellbound for about 15 minutes next to the workers, forgetting during this time where I was going and why. Two girls deftly removed old paint from elements of the facade, doors and windows of the old building. Decorative metal and wooden elements, the existence of which could only be guessed at. Do such work with an open fire, for example, using a gas burner, as I once did when cleaning the pickets of an old fence on garden plot, it was impossible both from the point of view of work safety and the safety of decorative finishing elements.

After the appearance in my workshop of good construction hair dryer I realized that the range of its use on the farm turned out to be much wider than I had previously imagined.

WHY ARE BUILDING HAIR DRYERS NEEDED AND WHERE ARE THEY USED?

  • Removing old ones paint coatings, synthetic wall finishing. Old paint can be easily removed with a metal spatula. The main thing is not to forget about good ventilation of the room during such work. .
  • Removing stickers, removing linoleum and vinyl coverings, carpet tiles based on synthetic fibers. A hairdryer will help you quickly remove price tags and other labels from a new product. The design of the device allows it to be placed stably on a horizontal surface.
  • Removal/application of protective coating (strips).
  • Softening/melting of resins, solder, bitumen, wax, restoration of deformed candles, removal of candle wax. Using regular candles different colors and ceramic molds, you can easily make an original gift.
  • Waxing of skis, furniture, antiseptic wood treatment.
  • Loosening rusted/tightened metal screws, nuts, bolts, hot landing, heat shrink treatment.
  • Defrosting water pipes and sewer pipes, refrigerator freezers.
  • Defrosting and drying frozen car locks.
  • Clearing ice from machine elements and mechanisms.
  • Soldering thin-walled copper pipes. For soldering, a special nozzle is used, which allows you to heat the soldering area from all sides.
  • Molding plastic pipes and all plastics with a low melting point (polyethylene, polyvinyl chloride, etc.), welding of plastics.
  • Molding of plastics with a high melting point (plexiglass, etc.).
  • Forming and bending of wooden parts.
  • Repair of surfboards, skis and other sports equipment, repair of bumpers and other plastic parts of cars.
  • Smoothing out bulges after gluing PVC labels.
  • Garden hose connection.
  • Drying paint, varnish, plaster, mortar and plaster, wood, and construction joints before applying insulation or sealant.
  • Cleaning and disinfection of cages for animals and birds, extermination of pests.
  • Drying the walls of rooms after leaks.
  • Dismantling of microcircuits and other radio elements, tinning.
  • Lighting coal in the grill.

Special safety requirements that we would like to pay special attention to.

  • Do not use the tool in an explosive environment, near flammable liquids, gas, paint, varnish and similar materials, toxic and flammable gases may be released.
  • Never use the tool together with chemical solvents and in poorly ventilated places.
  • When cleaning old paint, heating flammable substances (bitumen, lubricants...), you must have fire extinguishing agents on hand: a fire extinguisher, sand, asbestos materials or fiberglass.
  • Before storing the instrument, make sure that it has completely cooled down; to do this, you need to install a hair dryer on back side in a vertical position, or hanging.
  • When removing old indoor coatings, you need to be aware that paints containing lead, which is a highly toxic substance, may have been used in the past. When removing old paint from wooden windows, be sure to use a nozzle that prevents hot air from heating the glass, which can lead to glass breakage and injury.
  • Heating gas pipes may cause an explosion.
  • Keep pets away from the tool working area.
  • You should not use technical hot air gun as a hairdressing tool.

What you need to pay attention to when choosing a hair dryer.

The design of all construction hair dryers is basically the same: a heating element (coil) heats the air, and an electric motor, using a fan, drives it through the nozzle into the work area.

Prices for construction hair dryers

Don't be fooled by the low price. I paid about 300 rubles for my first hair dryer, although there were devices on the shelves nearby that cost many times more. But after just a few minutes of use, something crackled inside the hair dryer and there was a smell of burnt plastic in the air. Very high price for devices with similar characteristics well-known companies typically characterizes the ability to work continuously for longer periods of time. These are devices for so-called professional use.

The main characteristics of a hair dryer are power consumption (for household use - 1800-2000 W) and performance. Average temperature range air jet from 50 to 600°C.

In the inexpensive price range, the most common models of hair dryers are those with step-by-step temperature control.

Hairdryers with smooth temperature control allow you to more accurately select the temperature to perform the job.

It is desirable to have a device that “maintains a constant temperature,” which protects the tool from overheating, thereby extending its service life.

Some models designed for specific work, when it is important to maintain a strictly defined temperature at the work site, have operating temperature displays. More simple indicators, for example, with a line of LEDs they only allow you to roughly estimate the temperature. On models with step adjustment, the approximate temperature corresponding to each stage of the switch is usually indicated.

In the nozzle of the majority hair dryers there is a reflective mirror .

It serves to increase heat transfer and reduce the processing time of materials.

A simple pistol-type handle allows you to use the hairdryer in hard-to-reach places. A closed handle sometimes limits the working area, but is able to protect the hand from a reflected stream of hot air and contact with a heated surface.

Special structural elements of the housing are designed for stationary use hairdryer. This use allows you to do work with both hands, or save time when heating mastics, solutions and other materials .

A removable heat-protective casing in the form of a ring, installed on the nozzle, allows you to protect the worker from burns, and the processed material from accidental contact. It is recommended to remove such a casing only when working in hard-to-reach places .

It is advisable that the one being purchased hair dryer was equipped with a set of the most commonly used nozzles. Nowadays there are many specialized nozzles. But in household it’s quite possible to get by with 4-5 universal ones nozzles:

  • nozzle that lowers the temperature,
  • glass protection nozzle,
  • nozzle with reflector,
  • flat nozzle.

Hot air is used in many construction or repair work. To form a flow of hot air with a temperature from 100 to 650 o C, use construction or technical hair dryer. Sometimes it successfully replaces The advantage of this tool is the absence of open flame and the ability to adjust the temperature of the supplied air. The technical hair dryer has a wide range of uses:

Such a wide range of works determined the popularity of this instrument. There are some key points, which you need to pay attention to when choosing it. The main technical characteristics that require increased attention are power, air flow and temperature range.

Power varies from 900 to 2300 W. The more powerful the technical hair dryer, the faster the work is completed. The rate of heating of the workpieces also depends on the force air flow or air supply performance. This characteristic is usually in the range from 200 to 700 liters per minute. Another important parameter- supply air temperature. It varies from 100 to 700 o C.

When choosing a technical hair dryer, pay attention to additional functions, which will be useful in your work. For example, the ability to adjust the temperature. Smooth adjustment is easy to use: you can accurately select the temperature for each type of material. If you choose a model with a step switch, then you need to make sure that there is a maximum number of operating modes. Many professional heat guns have a built-in temperature control system. It regulates the heating of the air flow regardless of the load. This function avoids overheating of the tool and surface. Some types of work require rapid cooling. There are models that have a cold air supply function.

Ergonomic details are also important. So, pay attention to the handle. Models with open handles are smaller, but the protective cover protects your hands from burns. Must have protective covering and nozzle. In addition, the tool simply must fit comfortably in the hand: you will have to work for a fairly long period of time, and comfort is not at all an excess.

For more efficient work use special nozzles. There are drying, cutting and soldering. There is a special round nozzle that forms a directed air flow, and there is a protective one that will protect heat-sensitive materials from overheating.

As when choosing any equipment, you need to pay special attention to the manufacturer: good technical specifications appropriate quality must be attached. Good recommendations received a Bosch technical hair dryer. This manufacturer consistently pleases high level execution and a large assortment, allowing you to choose a tool for any purpose. From products domestic producers You can highlight the technical hair dryer "Bison". It is quite competitive in today's market.

Although this device is called a hair dryer, it is not intended for drying hair at all, as it is too powerful for this. With its help you can lay linoleum, soften some varieties roofing, and also cut roofing felt. However, before visiting the store in order to purchase this tool, you need to ask what distinctive characteristics this equipment has, as well as what features you should pay attention to.

Purpose of a hair dryer

Construction hair dryers, the purpose of which will be described in the article, should be selected taking into account an acceptable cost and fairly famous manufacturer, which has proven itself in the market for relevant products. By using of this equipment you can dry the glue, connect different types materials before laying insulation, dry the joints tiles, putty, connections of stucco elements. This equipment will allow you to remove the remains of old paint, varnish, wallpaper or parquet from the surface of furniture, floors or windows. With its help you can get rid of veneer or tiles. To do this, it will be necessary to use not only hot air, but also a spatula made in the form of a scraper. The device will form polystyrene or polyvinyl chloride products, and you need to use a temperature within 300 degrees. Whereas if you apply a temperature of 500 degrees to the surface, you can deal with plexiglass or acrylic.

This device also works excellently with rods made of polyurethane and pipes. If you are interested in construction hair dryers, the purpose of which you should know before visiting the store, then you should also pay attention to the fact that this tool will allow you to defrost icy pipes, drains, and locks. With its help, you can easily remove ice from the surface of wires and steps. The equipment will help disinfect wood that has been affected by microorganisms or bugs. The device will destroy anthills that were built in a blind area or a stone wall. If there is a need to glue dimensional elements By increasing the exposure time and heating the connection point, you can use a hair dryer. Among other things, it will help speed up the setting of two-component glue. Quite often you have to remove polyvinyl chloride stickers that were attached with glue. In this case, there is also no way to do without an appointment.

What else can you do with a hairdryer?

Construction hair dryers, the purpose of which should be of interest to the consumer intending to buy this tool, will allow hot pressing and soldering of PVC pipes. Using this equipment you can shrink hoses and handles. The tool will weld pieces of polyvinyl chloride film overlapping, which also applies to tarpaulins. This may include elements floor coverings, made of PVC. Once the bitumen has melted, it is easy to repair the roof. As for bitumen cardboard, it can be easily cut or welded.

Construction hair dryers, the purpose of which will be interesting to any modern consumer who has visited a building materials store, allow you to solder pipes using silver or tin solder. For the first you will need a temperature of 400 degrees and above. Pipes made of copper, as well as cable ends and wires can be quite simply unsoldered or soldered. As practice shows, the area of ​​use of this instrument, which is also called a hot air gun, is quite wide. That is why experts advise having such equipment on the farm.

Main technical characteristics

According to experts, all models of industrial hair dryers are practically the same in design. which is located on a ceramic insulator, enclosed in a durable plastic case, it withstands the effects of impressive temperatures quite well. By the way, the heating element has the shape of a spiral. which are presented in the article have electric motor, the last of them is equipped with one or two impellers, the engine operates at fairly high speeds. Its task is to transport heated air to the nozzle. There, air masses begin to work, ending up on the surface.

Features of the tool by air flow temperature

If you are considering construction hair dryers, the characteristics of which should be known to you before making a purchase, then you should know that the maximum permissible temperature when operating most of the device will be equal to 600 or 650 degrees. However, you can also find quite powerful models on sale, they have this parameter sometimes reaches a limit of 800 degrees. Productivity is determined by the volume of air that is pumped through the nozzle in a certain unit of time. If we are talking about a middle-class model, then this figure can vary from 200 to 650 liters per minute. This parameter will be related to the heating temperature.

Performance Tool Features

A construction hair dryer, prices for which vary from 1,500 to 28,000 rubles, sometimes has more impressive capabilities if it is characterized high temperature and productivity. Its power, which consists of the power of the fan and coil, will increase. This parameter changes from 500 to 2500 watts. If it exceeds 2000 watts, then the device will be quite impressive in size, expensive and heavy. Experts advise choosing models for home use, the power of which does not exceed 2000 watts.

Models with adjustable air flow volume

A construction hair dryer, the prices of which may vary, sometimes has volume adjustment. The ability to adjust can be very useful if overheating of the surface being worked on is extremely undesirable. Adjustment is also necessary if the part is very light, i.e. it can be blown away by a stream of air.

Temperature-adjustable models

If you are interested in the Interskol construction hair dryer, then you should decide whether temperature control is important to you. It gives the master a lot of opportunities. Thus, you will adapt the equipment to work with all kinds of materials. If you choose a hairdryer that belongs to the hobby class, then the adjustment will be stepwise, it will assume the presence of several fixed values.

If you are interested in a construction hair dryer with temperature control for professional use, then here the possibility of adjustment will be smooth. Such a device can handle any materials, even those that are very difficult to process. By visiting the store, you can choose the adjustment method, which can be slider or electronic.

Hairdryer with an electronic system for maintaining a certain temperature

If you want to purchase a hair dryer with temperature control, then it is important to pay attention to the fact whether it has an electronic system for maintaining the temperature at a certain level. In the passport or instructions, this functionality may be listed as heat flow stabilization. If this parameter is executed on electronic circuit, then it will allow you to maintain required temperature of forced air, and will also protect the heating coil from wear. Most often, such models are equipped with built-in memory; it remembers the temperature at which you worked until the moment you turned it off. Choosing a Bosch hair dryer with the ability electronic system support certain temperature, you will get fast and comfortable work, but a professional model of this type will be quite expensive. For those craftsmen who want to choose a tool to solve household problems, this option cannot be called suitable.

Possibility of using cold air flow

When visiting a store, it is important to choose a hair dryer, the reviews of which will be only the most positive. Thus, home craftsmen recommend purchasing models that have cold air blowing onto the surface, as this is quite an impressive advantage. If you cool the place where plastic pipes are soldered with cold air, you can reduce the time required for the work, and this is important. At the same time, wait until hot surface It will cool down on its own, you won’t have to anymore. You can choose an option that involves one of two ways of blowing cold air. This may be the presence of another nozzle or the ability to turn off the spiral. The first method is more advanced and modern, but the second allows you to cool the coil after work quite quickly if there is a need to put the device back in place.

When gluing thermoplastic surfaces, when the first nozzle will work to heat up and the second will cool the base, there is a need for a model that has a second nozzle in its design.

Existence of a filter for external air

It will not take long to repair a construction hair dryer if the device has a filter for incoming air flows. This functionality is convenient when the device is intended to be used in dusty conditions. In the absence of a filter, air contaminated with dust will get inside, damaging the spiral. As a rule, some manufacturers supply a hair dryer with a filter that can be easily removed, which is why it will not cause any difficulties during operation.

Models with control indication

When performing fairly delicate manipulations, insufficient heating or overheating of the surface can completely ruin the part. In this case, there is a need to control the temperature of the air flow. Some versions of construction hot air guns are equipped with a control indication, which is in the form LED backlight or small screen.

Hairdryer equipment

Attachments for a construction hair dryer can greatly facilitate certain types of work. For example, focusing round nozzles are needed to manipulate copper pipes, as well as welding tape. If you are constantly faced with the need to remove old paint, wallpaper or varnish, then you should choose a model that has flat nozzles. To weld elements made of polyvinyl chloride, you will need crevice nozzles. For a construction hairdryer, these elements can be useful in cases where there is a need to cut foam plastic. Here you will need a cutting nozzle.

User manual

As you know, the temperature of a hair dryer can be very high. In order for the thermoelement not to require replacement, it is necessary to direct the air at a certain angle, which is 45 degrees. Do not work near flammable or combustible liquids or objects. It is important to ensure that the treatment surface and the device itself do not overheat. However, you should not check the air temperature with your hand, as you will certainly get burned. After completing all work, you need to allow the hot air gun to cool down, but do not touch its working surfaces. It is important to take into account the fact that on hot days, individual parts of the device can take a very long time to cool down.

If it is necessary to remove varnish or paint, you should use only the scraper that comes with the kit. In this case, the master must use a respirator. It is recommended to work with the tool in a well-ventilated area or outdoors. This will not only be safer, but also less harmful to the health of the master. Of course, in winter time It is worth taking care of the availability of a special room.

Construction hair dryers produce a stream of very hot air with temperatures up to 800°C. These tools are used instead gas burners, soldering irons and even welding machines. And some even use them to heat up lunch in the harsh conditions of a construction site.

Application

A construction hairdryer can be used to remove paint, varnish, film and wallpaper, dry surfaces, and defrost icy pipes, steps and wires. Sheets of linoleum, roofing felt and bitumen are connected under a stream of hot air. At 300°C, polyvinyl chloride and polypropylene pipes, and at 500°C - plexiglass. You can also use a hairdryer to heat up contact adhesive for better adhesion, heat shrink tubes when connecting wires, “weld” polymer rods, tin and copper wire.

Power and maximum temperature

Hairdryers with a power of 2500 W are the largest, heaviest and most expensive. Such models are very “gluttonous” and seriously load the power grid. For home use, a tool up to 2000 W is sufficient. The continuous operation time of ordinary household models is up to 10 minutes; professional industrial hair dryers can work up to 30 minutes.

The temperature of the air flow depends on the power. This characteristic should be taken into account when working with refractory materials, for example, roofing felt. The temperature limit of most household hair dryers is 500°C. Professional models the air flow is heated to 650°C, industrial - up to 800°C.

Performance

The performance of a hair dryer is the amount of air it produces per minute. The higher the indicator, the faster the surface heats up. For middle-class models, this figure is up to 450 liters per minute. Professional construction hair dryers up to 650 l/min are used to work on large area.

Weight

The average weight of the tool is from 500 g to 1.5 kg, including packaging and all equipment included. The tools differ in weight by 100 - 300 g, depending on the electronic “filling”, length and cable protection.

Air flow adjustment

If you often work with delicate surfaces, such as epoxy and vinyl, or the workpiece needs to be processed with a light air flow, it is recommended to purchase a professional model with an air flow regulator. For most of the tasks described at the beginning of the article, you can choose a regular household model without a regulator.

Temperature adjustment

Materials with different compositions require different temperature regime. Most household hair dryers have two operating modes: low (about 300°C) and maximum (about 500°C). Professional models have a cooling mode (50°C) and precise temperature control.

The regulator can be mechanical or electronic. In the latter case, the temperature is set using buttons and shown on the display. The electronic regulator allows you to adjust the temperature with an accuracy of a degree and increases the service life of the heating coil. At next switch on the tool warms up to the last set value.

Cold air

When the spiral is turned off, the temperature of the air flow drops to 50°C; there are models with a separate nozzle for warm air. This function is needed to cool the tool and will be useful when working with fast-melting materials: stickers, vinyl and plastic.

Air filter

A filter is a must-have option on a production site where a cloud of construction dust hangs in the air, since without a filter, small particles can destroy the heating coil in a few days.

overheat protection

When working with a hair dryer perpendicular to the surface, the air flow is reflected from the material and returns back to the coil, which can lead to overheating of the tool. In this case, a “thermostop” function is provided, which turns off the thermocouple when the engine overheats or due to returning hot air.

Thermal cover

There are models with both removable and non-removable heat protection casing. To remove the “self-adhesive” you do not need to remove the casing, but to work with parts that you simply cannot get to, you will have to remove it. The average diameter of the nozzle in the casing is 60 mm. When the casing is removed, only a metal nozzle with a diameter of 30 mm remains.

Frame

The most common form of a hair dryer is the “gun”. It is advisable that the handle be rubberized or equipped with rubber pads - this way the hand will not slip while working. There are handles open type(standard pistol design) and closed, with additional external protection. The closed handle prevents the hand from touching the heated surface and protects from hot air. For work in hard-to-reach places, there are cylindrical models without a handle.

It is recommended to give preference to hair dryers with a power cord at least 3 m long. It is much easier to store the tool with a loop on the cord or hooks on the body. Hair dryers cool down the fastest when they are suspended.

Equipment

Most construction hair dryers are equipped with 7 – 8 nozzles.

Flat attachments, like those on a hair dryer, are designed to remove old coatings and bend plastic.

Small round nozzles - for precise heating of welding tape and copper wire.

A reflector nozzle (similar to a scraper with a rounded end) is needed to heat polymer pipes and deform and heat shrink tubing.

Welding mirror - a flat nozzle for contact butt welding of plastic parts. The parts are pressed against the mirror, warmed up, and then pressed against each other.

Side (glass-protective) nozzles are needed to remove paint from the frame without heating the glass.

The cutting tool is a thin flattened tube. Used for cutting foam plastic and other soft materials.

A crevice nozzle is needed for “welding” using wire or polymer rods. It fits onto a small round nozzle and features a separate channel for feeding the bar and a spout for pressing the bar to the surface.

A household hair dryer will be effective when working for no more than 5–7 minutes in a row on materials with a melting point of no higher than 560°C (copper, aluminum).

If you do not plan to work with easily melting materials, smooth temperature control is not necessary.

Professional models are used for long-term work when a closed handle is needed; when working with materials where precise temperature control is important; when you have to work with hard-to-reach structures, which can only be approached by removing the protective casing.
