How to measure exactly vertical line on the wall. Preparation for work

The laser level allows you to smooth walls and gender The laser level is great helper in repair work ah of any complexity, but in order to correctly determine the necessary point, you need to know how to use it. Buying such a tool will help both a novice specialist and a professional, and ease of use makes it quite popular among builders.

Laser level for the floor: rules for working with the device

These settings must be made prior to pouring. The device is installed in the middle of the room and the level of construction of horizontal planes is turned on. Immediately a line will be displayed on the wall, indicating the future markup.

Read the instructions carefully before using the laser level.

The laser beam will also be reflected on any object placed in its path.

With the help of a ruler, you can easily find the most protruding or drowning part of the room. This data is used to determine the level of the screed on the floor. Knowing the required height, beacons are installed. Further, after finishing work, you can use the device to see if the screed is made correctly and if there are any irregularities on it, and if there are, then align it.

How to work with a laser level: videos and types

There are several types of levels, and work with each is slightly different. Static building levels - crossliners or multi-prism builders - the most common type of device, it is used for work of small or medium volume, and is able to project both intersecting lines and highlight certain points - a plumb or zenith.

The pluses include high accuracy and a wide capture angle, and the minuses are a short range and poor line visibility in sunlight.

Rotary line builders - level or multi-prism devices. The principle of operation - they show both a horizontal and a vertical plane, therefore, they can designate lines according to the entire perimeter of the room. It is the most expensive device and is used for large scale construction as well as building landscape design. Pros: 360-degree projection capability, long beam range, self-leveling function, low error. There are practically no minuses in modern models, the only thing is that you need to work with it carefully, in special protective glasses and make sure that the beam does not get into the eyes of animals or people.

Laser levels may differ in functionality, shape and price.

Static axis builders - point lasers or pointers - this is the simplest version of the device, it is able to project only one point on any plane, it is most often used for domestic purposes - for wallpapering, placing shelves or paintings. The advantage of this tool is its high beam range - up to 30 meters. Among the minuses - if you need to do a large number of work and measure many surfaces, then it will need to be constantly rotated in the required direction, a high percentage of error is also possible - even a slight deviation can make the wrong parameters and all marking will be carried out with an error.

Each device must be accompanied detailed instructions, which indicates the steps for assembling the tool, what is included in its package and how to bring it to working position. It is also necessary to carefully read the safety precautions to avoid an accident.

If the device has a battery, it must be properly and fully charged, if batteries - install. Then you need to check the health of the level by turning it on - the appearance of a beam indicates its normal operation.

Experts give a number of tips to help avoid mistakes in working with laser level :

1. After installation, there should not be any foreign objects on the beam barrier, otherwise there will be a curvature of the line.
2. The distance must be used the most optimal, for each type of device it is individual, so you must follow the attached instructions. If you reduce the distance, the indicator will be more accurate, and to work at a long distance, you must use a special beam receiver that comes with the kit or buy it separately.
3. When working with a level, it must be set to flat surface or tripod. It is impossible for the laser to oscillate, because then inaccurate data will be obtained, and they will need to be re-set.
4. For precise leveling of the device, some models have a built-in horizontal bubble level with which it is set, and in more expensive laser levels, a signal is given if it stops, then an accurate check and installation has taken place, it is ready for use.
5. While working with the device, it is necessary to warn people and remove animals from the place of repair, because the laser beam, getting into the eyes, can cause injury to the retina.

Recommendations: how to use a laser level to level walls

The device will allow you to check such parameters for leveling the walls. The level of wall curvature - you need to install the device parallel to the wall, then use a measuring tool to check the distance from the floor to the line throughout the entire length of the beam. Similarly, the verticality of the corners is checked. You can define a line for attaching wall-mounted decorative items - paintings, furniture, plasterboard ceilings. View and get a vertical line indicating the place for wallpapering. See the right line for laying electrical wiring.

The laser level is used by both professionals and amateurs.

If the device has a self-leveling function, then it is easy to install it on the surface without any effort, and it is also easy to work with a similar level.

In case of deviation from the norm, a signal is often given, which indicates the need for re-installation. The device with a manual leveling function has two bubble levels on its surface, allowing you to accurately position it to obtain the correct data.

Sometimes there may be erroneous indicators in the device that occur when using it for the floor.

This happens for several reasons:

• If during the measurement some obstacle has become in the way of the device - a window or any other object;
• Dust or a drop of water fell on the radiation window, then the beam can be repulsed in any direction;
• A sharp change in temperature - the level was taken out from a warm room to a cold one and vice versa;
• The appliance has been broken as a result of a fall or impact.

The laser level should be placed on a flat surface.

For such problems, please contact service center, which is necessarily indicated in the attached documents for obtaining repairs. You can purchase a course or lessons, where to find training, correct use device, check how the markings and the horizon are carried out. Working with a level when laying tiles on the floor, you can get cross lines that will serve as a guide for the central row of joints, greatly simplifying the work process.

To choose the right level for yourself, you need to focus on such nuances:

• If the level is required for normal domestic use, small repairs, including pasting wallpaper or installing a cabinet, then you can get by with a prism laser, its use is suitable;
• For the most simple jobs those who only need to get point marks, a cheap laser level will come in handy.
• If there is a large amount of work to be done, and it will be necessary to project beams both indoors and outdoors, a rotary level cannot be dispensed with.

Laser level: how to use (video)

Many firms famous brands present their products, each of them still has pros and cons, but the choice is up to the buyer. You can also buy most simple options- hydraulic hose or bubble, having the most low cost. Floor cord will cost much more.

Before proceeding with leveling the floor surface, it is necessary to beat off the horizontal level of the room. In other words, draw perfect horizontal lines on the walls that you can navigate when leveling. Today we will analyze how this can be done the easiest way using traditional and modern devices.

What tools are there to beat the level?

In order to beat off the level of the floor, you can use:

• hydraulic level;
• laser level;
• level.

The last option, that is, a level, is difficult to work with and requires knowledge, therefore it is rarely used for these purposes.

Using the water level for marking

Most loved by builders is the hydro level (water level) - a transparent flexible tube (like a dropper, but with a large diameter) at both ends of which there are two control flasks with digital markings. They make it easier for beginners to level up, but for experienced builders they are practically useless. Often these flasks are even removed as unnecessary. So, in fact, any transparent hose with a length of 3 - 25 m can be considered a hydraulic level. The accuracy of the level reading will not suffer.

The hydraulic level consists of a hose and two transparent flasks, which, when used, must be tightly closed with lids.

The principle of operation of the hydraulic level is based on the properties of communicating vessels, in which any homogeneous liquid (for example, water) is always set clearly at the same level. If the hydraulic level is filled with water, and then both ends are lifted vertically upwards, then we will get just such communicating vessels. And the surfaces of the water columns in both parts of the hose will necessarily match.

The principle of operation of the hydraulic level: water in communicating vessels is set at the same level

How to beat off the horizontal level with the help of a hydraulic level?

Working with a hydraulic level involves the participation of two people, therefore, if you carry out repairs yourself, then you will have to invite an assistant during the leveling process.

The steps for leveling are as follows:

1. Filling the hydraulic level with water, lifting the ends of the hose up and bringing them together. At correct work tool, the water in both parts must be combined. If this does not happen, then most likely there are air bubbles in the water. They need to be driven out by shaking the hose, tapping on its walls. This will allow the liquid to become homogeneous, then the hydraulic level will work correctly. Due to the reluctance to fiddle with bubbles, some builders prefer to pour into a tube boiled water. But not at all objects it is possible and convenient.

Another reason why the hydraulic level may refuse to work is pinching and creases in the hose. It must be ensured that the central part of the hose, which remains lying on the floor during measurements, is not pinched at any point. That is why the hydraulic level must not be stepped on either during measurements or after (creases may appear).

2. At the edge of the wall (usually near the very corner), the first person from the brigade applies one end of the hydraulic level.

3. On the other edge of the wall, a second person at any distance from the floor makes a mark (usually at eye level) and applies the second end of the hydrolevel to it. The main task at this stage is this: to combine the water level in your tube with the mark on the wall. This can be done by moving the tube up and down, naturally, without sudden movements, carefully. After the water level coincided with the mark on the wall, the same level should be established at the first end of the hose, which, as we remember, is motionless in the hands of the first person from the brigade.

4. After about 20 seconds, the first person draws a mark on the wall at the level of the water in their tube.

5. The transfer of the same label in exactly the same way is carried out on all walls of the room.

6. Beating (application) horizontal lines according to the marked marks using a chopping cord (sold in hardware stores, resembles a tape measure).

Through such simple actions you will be able to make a level beating throughout the apartment.

Laser level - a new generation tool

Working with a laser level (laser level) is even easier, one might say - a pleasure. However, such a pleasure costs a lot, so this tool is purchased mainly by professional builders.

The laser level draws vertical and horizontal lines on wall surfaces.

Laser level - a small device (it usually comes with a telescopic tripod or stand) capable of emitting laser ray. This ray draws an ideal horizontal line on the wall (in most modern models also vertical).

The laser level emits a laser beam in several projections

Stages of beating the horizontal level with a laser level

1. Installing the laser level on the floor or on a tripod.

2. Leveling the instrument. In expensive models, an automatic leveling function is often provided, which allows you not to worry about the evenness of the installation. Otherwise, you will have to align the bubble in a transparent flask (located on the surface of the device).

3. Turning on the device and getting a perfectly horizontal line on the plane.

Focusing on the horizontal line of the laser builder (level), you can level floors and ceilings, build podiums, nail shelves and perform many other repairs

4. Drawing this line with a chopping cord.

5. To obtain a horizontal line on another wall, the laser level must be turned in its direction and perform the same steps. This principle of operation is typical for positional laser levels, which belong to the budget line. More expensive models are rotary. They don't need to be rotated. When turned on, they immediately give a projection around the entire perimeter of the room.

The apparent simplicity of this procedure is deceptive. The master who performs it must be able to work with different kind levels, be careful, do not make mistakes in the calculations. An error of just 2 mm can lead, after a short period of time, to a complete replacement of the screed and flooring.

The purpose of this operation is to determine the level of the floor for the screed, i.e. level the errors of the base in height.

During the laying of floors, it is impossible to achieve an even horizon and a clean surface. There is always a slope and various ledges.

The screed holds the floor well only if at its thinnest point its thickness is at least 30 mm. Therefore, deriving the zero level, we find the most high place on the basis of the floor and, adding 3 cm to it, we determine the horizon along which the screed will be poured.

Floor Level Measurement Methods

To determine the level of the horizon (it is also called zero) you will need:

• laser or hydraulic level;
• roulette;
• pencil;
• a special cord for beating lines (you can make it yourself by rubbing a simple cord with chalk or charcoal).

The choice of level type depends on:

• the financial capabilities of the contractor (the price of the laser level is quite high, up to 20.0 thousand rubles, and when installing beacons for floor screed with your own hands, it makes no sense to buy it);
• skills (experience).

Determining the evenness of the floor without a laser level can be much cheaper. In the absence of experience with a hydro level, a laser level can be rented, which will not hit your budget in any way.

Hydraulic level

The simplest device with which you can beat off the horizon line (zero) and screeds is a hydraulic level. It is a hose with two transparent containers (flasks), which are marked. The work is based on physical property liquids in communicating vessels should be set at the same level.

In terms of the quality of work, it is not inferior to determining the level for pouring a floor screed using a laser level, it costs several times cheaper (you can make it yourself), though it requires the participation of 2 people.

Advice: in the absence of a water level at hand, you can make it yourself from a long rubber tube and transparent flasks, glass or plastic, which are fixed at its ends or from a transparent plastic hose.

Ideal for these purposes plastic tube used in diesel vehicles for fuel supply. In this case, flasks are not needed. The system is filled with water, after which the device is ready to work.

Operating Instructions

In numerous instructions given on Internet sites, it is clear that the authors have never worked with a hydraulic level. Therefore, we paint the entire course of work step by step.

1. At a height of one and a half meters, a mark is placed on the wall. This is the initial mark of the zero line.
2. Two people take a hydro level and approach the wall a meter apart. One of them should be next to the mark.
3. Approximately at the same (any, but preferably closer to the mark) height, a level is applied to the wall.
4. Wait 20 seconds for the water to calm down.
5. With simultaneous, slow up and down movements, the water level is matched with the mark at the first end of the hose.
6. Again wait 20 seconds and note the water level at the second end of the hose.
7. The procedure is repeated in the same order around the entire perimeter of the room.

It is important to understand that the marks are set in height to the horizon, and not to the floor, since it often has a slope, sometimes up to 10 cm. All marks are beaten off in one line with a building cord. If there is no cord, you can draw a straight line with a pencil using a rail.

Important: for beginner builders. If the hydraulic level at both ends of the hose is tightly closed, then during measurements it is necessary to achieve the coincidence of the water level in the flasks at the same digital values. If this is not done, then due to air pressure on water in a closed vessel, the measurements are distorted.

In levels with open ends, this is not necessary. Another thing is important here: when changing the measuring point, both ends of the hose are tightly closed with a finger. If the factory hose is transparent, it is better to remove the flasks. It's easier.

Starting from the horizon line, we find with a tape measure the highest place on the base of the floor (floor). It will correspond to the smallest distance from the horizon line to the floor. From it, the calculations of the screed line will be carried out.

Important: if there is no slope, but there are raised points in the form of tubercles, we remove them, and we measure the differences in floor heights in relation to the zero line.

How to determine the level of the floor, or rather the screed? From the smallest value of the measurement, subtract the thickness of the screed and make a mark. Along it, again along the walls, we draw a screed line, parallel line horizon. For convenience, we put a number of marks with a tape measure, measuring the distance from the horizon line.

Calculation example: from the horizon line (blue line) to the floor, when measuring in various places of the room with a tape measure, the results were obtained: 1.54 m, 1.53 m, 1.52 m, 1.50 m. The highest place at the base of the floor at the point where the tape measure recorded the figure 1.50 m ( minimum distance from the horizon to the base). Then the screed line (red line) will be at a distance of 1.37 m (150 cm - 13 cm) from the horizon line (the calculation is conditional, in most cases 3 cm is subtracted. In this case, the screed line will pass at a mark of 147 cm from the zero line).

The scheme for determining the screed line.

bubble level

In many materials considering various technologies beating the screed line, it is recommended to use a bubble level (planar level) for these purposes. Theoretically, such work can be carried out. In practice, no. Why? There are several problems here, the solution of which is not given by the authors.

1. How to check the evenness of the floor in the middle of the room? A meter level will show the presence of unevenness, but you can compare it with other elevation changes only when it is fixed on the wall, which will allow you to comparative analysis. How to project a protrusion on the base of the floor in the middle of the room onto the wall is not indicated in the recommendations.

2. In the instructions for determining the horizon of the screed with a bubble level, the following procedure is given:

1. A mark is applied to the wall, along which it is planned to fill the screed;
2. A level is applied to the mark. Shifting it to the side, they pass the entire perimeter of the room, drawing a line with a pencil. If the line has converged, the screed level is ready.

The process is really simple and fast, but how to account for the ledges in the middle of the room?

One more important point. Determining the "peephole" line for the screed, its thickness is either overestimated or underestimated. Filling screed, on separate sections less than 3 cm thick, leads to the destruction of the entire structure. Overestimation of the thickness leads to a significant increase in the load on the floors and an increase in the cost of work.

Conclusion: advice to use a bubble level is dubious.

Laser level

Installation of beacons for floor screed with a laser level is available to a novice repairman. We find a place in the room from where the laser beam enters other rooms (at least one), after that:

1. set the level at a height of 1-1.5 m;
2. we make beam marks in all rooms, so that when moving to another room, it would be possible to combine the laser beam with the already existing horizon line;
3. using the beam as a zero line, we find the highest point of the base in this room (there is no need to beat off the line - it is replaced by a laser beam);
4. we transfer the level to the adjacent room and combine the beam with the mark set earlier (we place it so that it gets into the next room);
5. determine the highest point of this room;
6. after measuring all the premises of the apartment (house), we find the highest point of the base of the floor of the apartment. From it we will calculate the screed line.

Tip: how to beat the floor level with a laser level for beginners? Just put on any stand. With the help of a gyroscope, the laser level automatically takes a strictly horizontal and vertical position inside the hull.

At the end of the measurements along the walls and corners, it is advisable to do the same in the middle of each room - a higher place can be located there. To do this, in random order on opposite walls along the screed line, we put self-tapping screws. We stretch the cords between them and take measurements with the help of a square. If the distance between the base of the floor and the cord is less than 30 mm, we raise the tie line by the same difference.

The results of measurements are best applied to the walls in the place where the measurement was made. Alternative option- draw a plan of the apartment, and on it fix the distance from the horizon line to the base of the floor. This will avoid errors and not repeat measurements in all rooms when leveling the base in one of them.

Rotary level

The development of technology and technology has brought to the market building tools the new kind laser level - rotary level. With it, measurements can be taken in 5 planes. Its feature is that it can work in large rooms, up to 200-600 m, which cannot be done with a linear laser level.

How to check the level of the floor with a rotary type laser level? Instructions for use completely coincide with the technology of zero level beating with a linear laser.

It is used mainly only by professionals of large companies, as it is very expensive.

Lighthouse line marking

How to put beacons under the floor screed? First, we determine the number of rows of beacons and the distance between them. When marking the line of lighthouses, you should follow simple rules:

1. the distance of the extreme beacons from the parallel wall is 10-30 cm;
2. the distance between the beacons is marked less than the rule;
3. the direction is perpendicular to the wall with the door, which will ensure convenient pouring of the last meters of the screed (you can bulge out into the doorway).

We will show how the calculation is carried out. To do this, we use conditional data:

• room width 6.8 m;
• rule - 1.5 m;
• the distance between the wall and the first row of lighthouses is 20 cm;
• the distance between the extreme rows is 6.4 m (7.1 m - 0.2 m - 0.2 m).

Given that the rule must cover the distance between the wall and the first row (20 cm) of beacons, the distance between the beacons inside must be less than 1.3 m, otherwise the rule will not be able to lay the second end on the next beacons. We calculate the number of lines of beacons between the extreme rows - 6.4 / 1.3 = 4.9 (5). This means that there are 6 rows in total (5 + 1), the distance between them is 1.28 m (6.4 / 5).

Resizing the rule also changes the calculations. For example, with a rule length of 2 m, the total number of beacon lines is 5.

For reference: with 4 rows we get 5 row spacing, therefore we divide the distance between the extreme rows by this figure.

Beating all the lines allows you to proceed to the finishing stage before pouring the screed - the installation of beacons.

Conclusion

Beating the screed line is within the power of any beginner in the construction business. The main thing is to be careful and do the work strictly in order:

• draw a horizon line on the wall;
• along the perimeter of the room, measure the distance from the markings to the base of the floor;
• subtract 3 cm from the shortest segment and mark this point on the wall;
• through the resulting zero point, draw a line on the wall parallel to the horizon line;
• measure the floor in the middle of the room. If necessary, raise the screed line;
• carry out calculations and put on the floor of the passage of beacons.

Any building must be reliable, stable, have a structure that resists destruction, and at the same time look beautiful and spectacular.

To fulfill these requirements helps the knowledge of the basic physical laws associated with operating loads and control of the distribution of gravitational forces.

They constantly act on building elements, directed towards the center of gravity of the Earth. Under their influence, any body without support falls down from a height, moves along the shortest straight line - the vertical, coinciding with the direction of the lines of force of attraction.

This law defines the operation of two main building appliances:

1. a plumb line indicating the vertical;
2. level that defines the horizontal.

They are built into various modern measuring instruments and allow high-quality marking and assessment of the state of surfaces.

Principles of operation of plumb and level

When the geometry of a building under construction is checked and its design is created, it becomes necessary to control the orientation of the horizontal planes, the accuracy of the alignment of the vertical load-bearing elements. Since ancient times, people have used a plumb line and a level for this.

The device uses a weighted metal weight in the form of a balanced cylinder with a sharp cone tip, which is tied to the end of a thin and strong twine.

If you raise the reel, then the weight will hang on the cord, stretching it into a straight line indicating the direction to the center of the earth - the vertical. It remains only to evaluate the orientation of the wall on it or to mark it.

If a scale calibrated in angular units is placed near a vertically stretched cord, then it can be used to measure the deviation of building elements from the nominal parameters.

What is a level

The principle of operation of this device is based on the property of the fluidity of liquids under the influence of gravitational forces. At rest, molecules liquid substance uniformly fill all the cavities of the volume in which they are located, and on outer surface create a strict and even plane called a mirror.

It is always located in a plane perpendicular to the vertical and is called the horizon, and the line drawn on it is the horizontal.

If water is poured into a cup, it forms a mirror in the horizon plane. When we tilt our vessel at different angles, the water mirror will stably maintain its perpendicularity to the vertical.

This property is used in building levels. Their vessel is made from clear glass in the form of a cylinder and pour liquid inside, leaving some air. The inlet is hermetically sealed, and then placed sideways on a controlled plane and the parallelism of the surface of the filled water is compared horizontally with the vessel wall.

Sometimes in life situation of the entire tool, the designer may only have a bottle of vodka. With its help, it is easy to check the horizontal surface or stability on it. But, it is better to use devices with a scale in angular degrees.

It is applied on the body in uniform divisions, according to which, due to the movement of an air bubble, the angle of deviation of the building surface from the level of the horizon is determined.

Numerous devices called building levels work according to this principle.

A plumb line with a level allows you to compare the correctness of the erection of building structures and draw horizontal and vertical lines on their surfaces at the end points.

Tools for drawing precise lines

With the help of a plumb line, you can top point determine the position of the lower, located on the same vertical. But in order to draw a straight line between them, you need to apply a ruler, and draw on it with a pencil.

However, there are a number of devices that greatly facilitate such work.

Building cord impregnated with a coloring compound

This device is sold wound on a reel or placed in a special case that excludes foreign contamination. Gel, liquid or powder in a special case quickly dyes the thread to transfer color to building structure.

You will need to attach one end of the cord to starting point line (you can just involve an assistant for a couple of minutes), and then take the reel to its end and pull the thread. Then it should be taken away like a bowstring and abruptly released. The cord will beat off a clearly visible and perfectly straight segment.

In this way, you can quickly draw a large number of lines horizontally, vertically or on an inclined plane.

Laser level gauges

Level-drawing devices based on the use of a laser are now widely used. Most simple designs have a laser beam source, which is switched on by power supply with a built-in battery.

They have bubble levels on the body with divisions, according to which the pointer body is oriented in space, after which a laser beam is turned on, drawing a line on the plane.

Even with a simple laser pointer, you can accurately draw a horizontal line on a wall. To do this, you need to put a bowl of water on a stool or table and place a floating object on it, for example, a piece of flat foam.

It remains only to put on top the usual laser pointer and direct it to one of the points of the line. Then the foam is rotated, and the light signal moves along a single horizontal level.

The disadvantage of this method is the difficulty of adjusting the height level of a home-made device vertically.

More complex structures, called plane builders, laser or rotational levels or levels, have a mechanism for scanning the optical beam in one or more planes located at different angles. Professional expensive devices used for can simultaneously draw up to five planes, have various complex technical settings.

The most popular are levels that create only two perpendicular planes that can be tilted at different angles relative to the horizontal by adjusting the mounting of the body on a tripod.

They immediately draw lines for laying out tiles, creating parallel steps and railings on inclined stairs, and performing other design ideas.

The devices described in the article are not the only ones. Manufacturers of measuring equipment for construction works produce them in an expanded range with different characteristics and technical capabilities horizontal and vertical definitions.

For example, we suggest watching the principle of operation of Bosch practical laser levels in the video below. This general appliance for similar models from other companies.

Write in your comments about the devices that you use more often.

laser building level- a technological device that replaced the water one. The device gives accurate results, reliable and easy to use.

The laser level is a simplified version of the level. The action of the tool is based on LED light emission, forming rays and points. The beam changes position due to mechanical, optical, electronic changes.

According to the principle of construction, two categories of laser levels are divided:

• prismatic or positional, the beam is based on a prism, a line is projected onto the surface;
• rotary, the beam is formed by a lens, capable of forming control points.

Prism laser levels are inexpensive and easy to use, the beam range is up to 20 meters. Rotary measuring tools are used by professional builders, have more possibilities, range increased to 500 m.

Before starting measurements read the instructions, take care of safety. Working under open sky, take into account the temperature range of the tool, the degree of protection against moisture.

How to bring the device into working position?

Before the production of work, the apparatus is installed in the working position, fixed, then adjusted.

The device has several modes:

• construction of horizontal lines;
• projection of vertical lines;
• cross construction mode. The vertical and horizontal lines intersect, forming an angle of 90 degrees;
• point projection mode.

Level setting

The plastic, rubber-coated body of the device can be installed on any surface. Rigid fixation device - main principle mounts.

Important! During operation, vibrations of the device are not allowed, with a shift, the results will be distorted.

To set the laser level use:

• even horizontal surfaces at hand: chairs, window sills, tables;
• mounting with a tripod to the wall, rods and tripods.

Wall mounts hold the tool suction cups or magnets, Velcro. The tripod allows you to raise the device up, the rod is convenient in marking the ceiling. Accessories are included with the purchase or purchased separately as needed.

Setting

Preparation of the device for operation consists in setting the level strictly horizontally, will depend on the type of laser level, does not require professional skills.

Plug and play tools will be ready automatically. Adjustment occurs in the range of 5-10 degrees.

When setting the working position, the device gives a sound or light signal.

Turning on, the laser level will project the desired beam according to established regime measurements.

A bright luminous line will appear on the surface, one or more, a dot, a cross.

note

When the instrument is moved, adjustment is always made again!

Setting the laser level manually is carried out alignment of the bubble in the viewing window of the apparatus to central position . Adjustment of position is made by the screws located on the case.

Precautionary measures

The safety precautions for working with the device are in eye protection. Direct exposure of the beam to unprotected eyes can cause various injuries and diseases, up to retinal detachment.

When working, be sure to use special glasses, avoid hitting the beam on those present, isolate pets. Goggles improve the visibility of the lines in sunny weather.

How to use?

Laser levels are distinguished by the following parameters:

• food type, rechargeable or from replaceable batteries;
• remote control remote control, switching modes from afar;
• self-leveling mechanism;
• beam angle, the ability to project marks around.

Comparing the characteristics, choose the most suitable option.

For floor

The laser level is useful for floor installation, starting from the installation of beacon rails when pouring a screed or when installing a self-leveling floor. The projected lines will help align the first row or floorboard, check the planes of the walls.

Lines crossed at right angles check the position and quality of the seams of the floor ceramic.

for walls

Horizontal lines are being laid for cladding ceramic tiles, mounting false ceiling, hanging cornices. If for some reason it is impossible to place the device high, a parallel line is manually drawn above the projected line using a tape measure and a plumb line.

Vertical lines are comfortable when sticking wallpaper, fixing the frame from metal profiles for, installation of window and door blocks. Circular mode will help with layout interior partitions, as well as for leveling and plastering walls.

Lines crossed at right angles are achieved by combining two modes of operation - horizontal and vertical. In this way, the correct laying of ceramic or PVC tiles is controlled.

For obtaining oblique lines, as, for example, when marking flight of stairs on the wall, change the angle of the device with the adjusting screws. The self-alignment mode is disabled.

For ceiling

The marking of single-level and multi-level ceilings is not complete without a laser level.

Built-in lights are marked as follows:

• mark the points of installation of fixtures on the floor;
• transfer points to the ceiling, directing the beam upward from the marking point.

Using the device as an electronic plumb line, stand-alone columns, holes for pipes are marked engineering communications in the cover.

Surface leveling

The laser level is capable of leveling the surface.

Leveling determines the position of the height of the surface at different points premises.

The device is attached to the wall or floor using a bracket, directing the beam along the plane of the structure.

Using a ruler or building square measure for irregularities and irregularities, identifying plane errors or setting beacons plastering works or screeds.

How to check the laser level for accuracy?

During operation, the device is transferred, transported. Measuring technology, operated at a construction site is not immune from shocks and falls. From time to time the device is checked for accuracy.

To check horizontal lines you will need:

• a tripod or a flat, solid base for setting the instrument;
• a room with a distance between two walls opposite about 5 meters.

Important! When checking, you must remember to align the laser level with each change of position manually or automatically.

Starting verification, the device is installed at the first wall (A), marking the center of the beam on its surface. Then level rotate 180 degrees, fixing the center of the beam on the opposite wall (B).

The tool is transferred to wall B without turning and adjusted with a tripod or base so that the center of the beam coincides with the point marked earlier on wall B. Thereafter rotate the level 180 degrees again.

Mark the center of the beam on wall A. The difference between the resulting points will be instrument measurement error. At a distance between walls of 5 meters, the error must not exceed 2 mm.
