A door closer is one of those devices that requires careful and regular care, since constant loads and daily cycles of opening and closing doors lead to imbalance of the mechanisms of this device. Such troubles are corrected by a rather simple adjustment process. This is exactly what we will talk about in this article, in which, together with the website, we will talk about how to adjust the door closer with your own hands.

Adjusting the door closer with your own hands: what is adjustable and what is not
Almost all modern ones have two or three points that can be adjusted at your discretion - with their help you can not only adjust the operation of this mechanism, but do it in such a way that it is convenient for you to use the doors. That is why the question of how to adjust the door closer is solved not only during operation, but also immediately after installing the device on the door. So what can be adjusted in this device? As a rule, this is the speed of closing the doors, the so-called closing (pressing the door leaf against the frame) and in some expensive models the door speed ranges from 80°-90° to closing. Let's talk about the purpose of such a division in a little more detail.
In principle, this is all that can be adjusted in a device such as a door closer. Agree, you don’t need more, because the most important thing is comfortable closing of doors without human intervention.
The concept of a closer
A door closer is a special device that is installed on entrance doors in public buildings to control their opening/closing. The mechanism allows the doors to close independently after they are opened by a person: it slowly and tightly pulls the door leaf to the frame.
The operation of the device is configured individually in each case. This depends on its location, intensity of use and physical activity.
For example, on door closers at the entrances of residential buildings and exits from supermarkets, a certain period of delay of the door leaf in the open position is configured. This is necessary so that a person can calmly leave or enter the building with his hands full.
In other public places with heavy traffic of people, such entrance door devices increase the force that must be applied to open the door leaf. This allows you to prevent premature failure of the door opening mechanism, since many users apply significant force when opening doors, especially when they are in a hurry.
How to adjust a door closer: features of setting up the device
Let's start right away by deciding what absolutely cannot be done. There are few such contraindications, or rather, prohibitions - only one, but violating it will lead to complete breakdown of the closer.
Do not completely unscrew the adjusting screws! Hydraulics usually manage the entire adjustment process - after unscrewing the adjusting screw more than two turns, oil pumped there under pressure flows out of the hole. You won't be able to refill everything at home.
To better understand the essence of the issue, you can watch a video about adjusting door closers.
We've sorted out the prohibitions, watched the video, now let's get down to theoretical adjustments, but let's additionally clarify one more point related to some extent to the above prohibitions. During the process of adjusting the mechanism, the adjusting screws need to be turned little by little - half a turn of the screw leads to a serious change in the speed of the door movement. And one more thing - by turning the screw counterclockwise, we achieve an increase in the speed of closing the doors, and by turning the screw counterclockwise, we slow it down accordingly. Now that the basic rules are clear, let's begin to directly address the question of how to adjust the closer? We will solve it point by point, although, by and large, all the most important things have already been described above.
And in conclusion, a small reminder about the correct use of a door closer - these are four golden rules that allow you to adjust the door closer with your own hands as rarely as possible. First, don't turn the screw more than two turns; secondly, do not force the door by trying to close it with your hands; thirdly, do not prop the doors to keep them open and, fourthly, do not ignore the instructions for use. Only if these rules are followed can a door closer serve for a long time.
A door closer is a device whose action is aimed at quietly closing the door. The mechanism functions like this: physical force is applied to the door, which creates an impulse that is transmitted to the device and acts so that the door opens and closes without sudden movements or noise. If you want to create a door closer with your own hands, you will need parts whose purpose is not related to the principle of operation of the door.
This is what a door closer looks like
Door closers are different. All differ in different dimensions and colors, as well as the design of the mechanism. Depending on the place of application, the installation for doors is:
- furniture - closers are used in compartment doors in the closet, pull-out furniture elements, in the kitchen, and so on;
- door closer – fixed on main doors, interior doors, as well as compartment doors in storage rooms and dressing rooms.
Existing door closer options
Furniture door closer options are built into the structure during its creation. But you can install door closers yourself by creating the device yourself. Configuration of closers by device:
- device with drive and teeth;
- camshaft application.
Door closers are installed at the top, bottom, and also mounted in door elements.
Upper door closer
This is a typical type of mechanism. There are options for installing door closers at the top:
The door closer installation is selected based on the door opening functions.
If the doors open when a person enters, then the door closer is installed using the first method, otherwise method 2 is applicable.
There is another option for installing the mechanism; it is applicable when the doors open in all directions.
Example of a door closer for a door opening in both directions
Parallel installation is carried out as follows: the mechanism is mounted on the door, the lever is mounted on the base of the door frame using a special plate.
Installation procedure
In residential buildings (apartments), rack-and-pinion closers with hydraulics are mainly installed. Using the example of a device from this group, we will consider the recommended procedure for the wizard. Having understood the specifics of the work, it is easy to understand the nuances of fastening other types of products.
Installing a door closer on a plastic door is absolutely identical to the procedure for installing it on wooden and metal counterparts.
Scheme is selected
If the door swings outward, a lever is fixed on the leaf; accordingly, the body is on the jamb. When opening inward, everything is exactly the opposite. But in any case, the closer is installed so that the adjustment screws are located on the side of the door hinges. This will facilitate the process of “adjusting” the position of the canvas and its further adjustment. And this will have to be done, since its “subsidence” will gradually appear. It’s not difficult to figure it out, especially since the product always comes with instructions that contain typical diagrams for installing a door closer.
Marking in progress
And here the master’s task is greatly simplified. The products are supplied with special installation templates. They are made on a 1:1 scale and are universal, as they take into account various ways of opening doors and hanging curtains. All that remains is to place the closer stencil in place and mark the drilling points for the channels for installing fasteners.
Fixing the components of the device
After marking, secure the lever and the mechanism body to the base with hardware (included with the product), and then everyone can connect the halves of the rod.
- Installing a door closer on a metal door has one feature. It is necessary to use so-called “bonks” in the process of drilling thin sheets. These devices are threaded bushings. The fact is that working with a conventional drill can cause deformation of the metal, and it will not be possible to correct this defect (straighten the dent) on your own.
- When determining the position of the lever, you should focus on its base arm. It should be located perpendicular to the door leaf. If the angle is less than 90º, then the “slam” of the sash increases.
Installing a door closer with your own hands requires utmost attention and accuracy. The slightest mistakes often result in a loose fit of the canvas to the doorframe and drafts in the room. Or vice versa, slow closing of the sash and increased heat loss. You shouldn’t hope that everything will be resolved just by adjusting the door closer - this is not always possible.
It is for this reason that the installation stage of the device is the most critical part of the work. Moreover, the service life of the canopies depends on this. If the mechanism is installed incorrectly, then in the near future the skew of the canvas is inevitable, with all that it implies.
You can determine how correctly the door closer was installed by the following signs:
- smooth opening/closing of the sash, without jerking or additional effort on the part of the user;
- absence of extraneous sounds (noise, creaking, grinding, etc.).
Choosing the right door closer
Before choosing a door mechanism, you need to familiarize yourself with its functions. The principle of operation of a door closer is to quietly, smoothly close the door. This is reflected in the following factors:
- Saving heat in the room.
- There is no noise when the door moves.
- Noise insulation. When the door fits tightly to the frame, there are no extraneous sounds from the street or another room.
Working principle of a door closer
For proper and long-term operation of the door mechanism, you need to make the right choice of closer. For the correct functioning of the door closer, as well as its long-term operation for its intended purpose, there are several rules, guided by which you can avoid mistakes when producing the mechanism or purchasing it.
Door closer operation diagram
Depending on the appearance, operation, and type, door closers have different pricing policies.
Operating rules
When operating door closers, you must follow very simple and understandable rules.
The devices do not have various anti-vandal mechanisms, which requires very careful and rather delicate handling of them. After choosing a closer, you need to make sure that its characteristics correspond to the conditions where the device will be installed.
- Closers are divided into classes from small - EN1 to large - EN7. This indicator is taken into account when choosing a device. The classes depend on the mass of the closer itself and inertia: the weight and size of the blade arm. For example, a device designed for a door leaf weight of 40 kg (EN1) will not be able to close a metal door whose weight is 120 kg (EN7).
- Do not assist the device in operation.
- You cannot keep the door leaf open if the mechanism does not have a locking function.
- Do not unnecessarily turn the adjusting screws installed on the valves.
- It is necessary to agree with the equipment seller about left or right opening.
Do-it-yourself door closer installation
A door closer can be manufactured, installed, and adjusted from various means. How to install the overhead door closer?
Detailed instructions for installing a door closer
Step-by-step instruction
If the kit does not contain a model, then the technical data sheet contains the exact dimensions and measurements according to which the door closer can be mounted.
Adjusting the door closer
After installing the door closer, a check is required. If the door opens hard, closes or slams, you can adjust the door closer with your own hands.
There are 2 screws on the closer device. They take on the main functions of the mechanism. 1 screw – speed when closing the door, 2 – adjusting the tightness of closing the door and its fit to the frame.
If the door slams, the second screw needs to be adjusted. You need to turn it slowly (a little - half a turn), then check that the door is closed. This must be done until the door stops slamming.
Door closer adjustment options
To close the door a little slower, you need to turn the screw clockwise, so that the speed is counterclockwise.
Closer with more than 2 screws
There are door closers with adjustment screws of more than 2 pieces. In this case, the technical passport indicates the purpose of each screw. In addition to the standard door adjustment screws (speed and clap), there are also screws responsible for other functions of the mechanism.
One screw serves as a door brake when opening. That is, you won’t be able to open the doors with a sudden movement. The second screw leaves the doors open. That is, if the door is wide open, then it will remain in this position and will not close.
Drawing and diagram for adjusting the door closer
Adjustment of the screws is also carried out slowly and by half a turn.
A door closer is a useful mechanism that ensures reliable closure of a doorway. But soon after purchase, many buyers have a problem with how to adjust the door closer. Despite its modest size and simplicity, this mechanism has several adjustment options, but it is necessary to take into account temperature conditions, type of doors, doorway dimensions and several other parameters.
Installation of aftershock
Now let's look at how to adjust the door closer to install the door closer. This mode allows the doors to close smoothly, leaving a small gap before closing completely. It also performs a function that ensures a tighter fit of the canvas to the frame.
In order to set the shutter, it is necessary to change the position of the second screw located on the closer body. When approximately 10-15 degrees remain until complete closing, the deceleration will work, and then the blade will be pulled to the end. The screw controls the speed of this movement.
The clap speed is adjusted using the adjusting screw number 2
Door closer device
A mechanical door closer is a device that is designed to automate the process of closing it. It is mounted either on the door frame or directly on its leaf.
There are usually three types:
- Gear driven
- Cam
- Spring
In essence, it is a simple alternative to the spring that was previously used on gates. But since the springs closed very sharply and quickly, their design had to be improved. The closer consists of a spring placed in a closed housing and a pushing piston. In the middle the piston is connected to a gear, this is adjusted by a lever from the outside. Turning the lever activates the wheel, which causes the piston to move. This way the door is closed.
Closer technical specifications
It is a mechanism that ensures automatic closing of the sash. Since in this case there is no human factor, the closing is done smoothly, without unnecessary effort. The simplest device consists of a spring enclosed in a metal case and filled with special oil. When the door is open, the spring compresses, and when the door is released, it unclenches and slams the door shut.
Such a simple device is rarely used today. Modern versions of the closer implement a more advanced torque transmission system.
- Toothed rack – mechanical rack and pinion transmission is carried out. In this way, greater smoothness of spring straightening is achieved. Not used in devices with a sliding channel.
- Cam - the transmission link is a profiled heart-shaped cam. By changing the profile, the required degree of spring compression is achieved, thereby ensuring the most comfortable mode of closing the sash.
It should be remembered that door closers, according to the instructions, are a mandatory element of special doors: fire doors and evacuation doors, since in this case keeping the doors closed is a matter of principle.
Do-it-yourself door closer setup
Manufacturers provide the opportunity to configure at least two or three parameters, door closing speed, delay and slam. On modern devices, there may be a speed control function in the range from 80 to 90 degrees.
Before proceeding with installation, you need to carefully read the instructions.
If you adjust the closer yourself, without the help of a specialist, and only have schematic instructions in your hands, you should pay attention to several things:
- Closers are used for doors of different types - both indoor and outdoor. Inside the house, it is permissible to set it to run slowly. For entrance doors, faster movement is recommended to prevent the entry of cold air or insects. We should not forget about the user’s personal preferences and seasonality.
- If a room is often used by a large number of people, then by setting up an intermediate passage, you can ensure the passage of several people at once. If you use a special screw, you can keep the doors open constantly.
- When adjusting the door closer with your own hands, many often forget about the door closer. It serves for faster closing. You should find the optimal value at which there will be no strong impact on the jamb or sudden closing.
The user himself selects parameters from the range provided by the manufacturer.
Purpose
General-purpose door closers are, as a rule, hydromechanical devices and are used to ensure guaranteed door closure. By design, door closers can differ in the type of mechanism used: either cam or rack and pinion. The reliability and service life of the door closer are determined by the minimum number of door opening and closing cycles that the door closer must operate without deteriorating parameters, regardless of operating conditions. According to the EN1154 standard, door closers must operate at least 500,000 cycles.
Setting the intermediate stroke
Usually the intermediate stroke is adjusted in unison with the main door stroke, but there are other options. For example, if you need to slightly reduce the speed halfway through the door closing. To do this, use the third adjusting bolt. This bolt serves to hold the door leaf in a certain position. For example, you need to add more closets to your apartment.
The screw can be adjusted so that the door remains open for a while, and only then begins to close.
What to do if nothing works out?
There are several reasons why the setup may not produce results:
- An inappropriate mechanism has been selected, the door is too heavy, and heavy objects are frequently hung on the door leaf.
- Incorrect fastening of the iron angle, misalignment of parts.
- Displacement of the holes for the screws on which the device is attached, unscrewing.
If one of the above points applies, then there are only two options - change the door, install a different closer. There is a third option - try to fix it yourself, but lack of experience can lead to worsening.
The lever must be positioned strictly perpendicular to the canvas, otherwise one of the parts must be moved.
What should you avoid when setting up a door closer yourself?
There is only one rule that should never be broken. Do not unscrew the adjusting screws more than two turns. The operation of almost the entire mechanism occurs thanks to hydraulics. When the adjusting screws are unscrewed more than two turns, oil begins to flow from the closer. The oil is pumped there under pressure, and pumping it back in with your own hands is quite problematic.
Unscrew the adjusting screws carefully and little by little. Scrolling at least one and a half turns will make the closing speed very sharp.
How to quickly adjust the door closer:
In fact, there is nothing complicated about how to adjust the closer. This is a fairly simple mechanism, but in order for it to always remain in good condition, certain measures and rules should be followed:
- You should not prop the doors with any object (chair, stool, etc.). In order to fix the position, it is enough to adjust the special screws.
- You should carefully read the instructions before you begin adjusting the door closer yourself.
- When purchasing a door closer, it is necessary to take into account the temperature conditions in which it will be operated. Some models are not suitable for use outside the home.
- When purchasing a floor closer, you should remember that you need to plan everything in advance, since such devices are installed along with the door.
The closer is a device for returning the door to its original position in automatic operation mode. This device silently and softly closes the open sash. If necessary, it holds the door leaf open. Many doors are equipped with modern, practical devices. At the same time, like any equipment, the door closer needs maintenance, adjustment and troubleshooting.
Types of products
Devices for automatic closing of entrance doors are divided into several types depending on the installation location.
Upper
This is a classic version of door closers, which is mounted on top of the door structure. One element of the product is attached to the door leaf, the second to the door frame.
Floor
Closers of this type are used in public places with high traffic, for example, in shopping and entertainment centers. The design of floor mechanisms uses a sliding rod. They are quite compact in size, attached to the floor covering, and are practically invisible.
Hidden
There are situations when the closing device needs to be hidden. Such mechanisms are made of two types: with a sliding rod or a combined loop-closer. The first option is installed on top of wooden door frames. In the second case, the device is hidden in a metal door hinge.
This product is considered the most inconspicuous opening mechanism for a door structure. However, such devices have serious limitations. They cannot withstand significant loads and are not durable. To extend the service life of such a device, it is necessary to reduce the pressure on it. Therefore, it is not recommended to use it for door leaves made of heavy materials.
Types of mechanisms and their design
To better understand the principle of operation of the mechanism, you need to analyze its basic varieties, this will make it easier to figure out how to properly debug a door closer.
For the most part, two types of this device are practiced:
- cam slide - provides soft sliding, practiced for low-weight canvases;
- gear lever - the most common type of mechanism; the movement of the spring is realized through gears; it can be used even for massive door leaves.
Depending on the method of installation, devices can be divided into three main types:
- Top-mounted (overhead) designs
are the simplest devices to use; their functions can be adjusted using several screws or valves located on the housing panel. They are mounted at the top of the sash, which is extremely convenient during installation. For street entrance doors, specialized oil-filled devices are manufactured, adapted for operation in hot or cold climates.
- Floor-standing.
Floor-mounted systems are also relatively easy to set up. They have proven themselves excellent in banking institutions, offices, shopping and entertainment complexes and where there are high demands on the appearance of doors. These devices are integrated into the floor and are almost invisible to visitors. Sliding type regulator mechanisms are used and are intended for doors weighing no more than 100 kilograms.
- Hidden-type devices
are quite problematic to independently adjust, since they are hidden inside the door leaf or on the floor, which complicates access to them. The devices are in demand where thorough cosmetic finishing and an ideal main façade are required.
According to the principle of operation of the device, they are as follows:
- hydraulic;
- pneumatic;
- electric.
Fixture structure
The structure of this device includes the following parts and mechanisms:
- cast aluminum body;
- spring;
- piston;
- adjusting screws (valve);
- gears;
- needle bearing;
- rubber seals;
- fastener
Operating principle of the closer
The basic component of the design is a spring system, which, when the door is opened, is compressed and accumulates the energy required to close the door. The compression process is carried out by transferring the force of the traction device to the spring. Toothed gears and racks move the piston, while oil flows through internal channels into the free part of the housing. During the reverse movement of the door, the spring straightens and ensures soft closing.
In what cases is the procedure necessary?
Adjusting the operation of the door closer is quite simple. You can easily do the setup yourself. It is worth understanding in what situations it may be necessary to adjust the parameters of this mechanism. The first thing to remember is that the duration of uninterrupted operation of any mechanism is directly based on the quality of its maintenance during the entire period of operation. As a result, 1–2 times a year it is necessary to inspect the closer and eliminate minor faults. This is especially important during the transitional change of seasons.
In summer and winter, climate conditions vary enormously.
Most door closers are filled with oil, and as you know, any liquid changes its state when the ambient temperature changes. In particular, in winter the oil becomes thicker and the movement of the door leaf becomes slower. In summer, everything turns out the opposite, so you need to prepare the door closer to the required level. Adjusting the device is also necessary if you notice any malfunctions or you simply don’t like the settings. If the device begins to slow down or the door leaf closes too hard and quickly, intermittently, and does not close for a long time, you can try to correct all this. Things are somewhat more complicated when the device fails, since a simple adjustment will no longer be effective and repair work will be required.
Instructions for setting up a door closer with your own hands
To adjust the device, it is not necessary to invite a specialist. All you need is a minimum set of tools and certain skills. The entire procedure will take a minimum amount of time and will make it possible to achieve the desired result by following the steps listed below.
- Before you begin the procedure itself, remember that the main thing is not to overdo it with the control valves (screws). It is acceptable to make only 2 turns, then difficulties may arise. The oil in the reservoir under pressure may spill out, and the hydraulic system of the closer will eventually lose its functionality.
- To adjust the speed of closing the door leaf, you need to learn only one tendency - by twisting the valve in a clockwise direction, it will gradually decrease. If you perform the action in the opposite direction, the closing speed will increase.
- There is a solution to the problem of only one person being able to get through. Since there is a third valve, the adjustment of which can ensure the door remains in a stationary position for a certain time. Consequently, even a group of people will be able to freely enter the room.
- Such a problem as a lack of effort to completely close the door leaf is eliminated by adjusting the valves responsible for the closing speed.
The key problem when adjusting the closer may be choosing the ideal solution.
The main task is to close the door completely so that there are no gaps left. It is necessary to correctly select the ideal time that the door leaf can remain open. It is also necessary to make silent closing possible; hard impacts on the door frame are unacceptable. This may cause damage to the canvas. And the worst option may be the loss of functionality of the mechanisms responsible for proper operation.
How to adjust the closing force so that the door does not slam?
To set it up yourself, you will need a flat-head screwdriver or an Allen key. The door opens all the way, special valves located at the end of the device are secured. Full fixation is carried out with the door leaf closed. By changing the degree of tightening of the valves, you can adjust the door to extremely comfortable closing. Valve number 1 is responsible for the closing force of the door.
If a fully open door closes too quickly at the beginning, the valve must be tightened, and if it is slow and the speed needs to be increased, on the contrary, it must be unscrewed. Valve number 2 is responsible for the speed of complete closing of the door leaf (slam). Some modifications have a third valve, which adjusts all the efforts of the door closer. When properly configured, the door leaf moves smoothly, without jerking. The result of proper installation and proper configuration of the closer will be a long service life.
Important! The control valves must not be turned out completely. Otherwise, they will cease to fulfill their functional purpose even after returning to their place.
How to weaken the opening?
Quite often the closer requires additional adjustment. If the mechanism is working hard, and effort is required when opening the door, you need to release the valves, the door will begin to function smoothly. The valves can be placed at the end or on the front side, it all depends on the modification of the device. You can find out the location of the valves by looking in the manual, where the manufacturer indicates the location of all components and elements of the door closing mechanism.
Position open
At times there is a need to keep the door open for a relatively long period of time. It is worth figuring out how to adjust the device so that the doors do not close, but remain open. In many modifications of closers there is an auxiliary hold open option for this. To set it to this mode, you need to open the door approximately 90 degrees, and then tighten the specialized lock. After such simple actions, it will be possible to leave the door leaf open when opening it to the configured degree. A special lock in the device will be activated and will hold the door in this position as long as necessary. If you need to close the door, you just need to pull it towards you, and it will be removed from the latch. If the door is not opened all the way, it will move in the same way as always, without stopping.
Nowadays, entrance and interior doors are increasingly equipped with door closers. Thanks to it, the process of operating the door structure is much simplified. But if you want the door closer to serve you for a long time, then it is important to inspect and repair it from time to time.
The process of adjusting it does not involve anything complicated. And although all this work should be carried out by employees of the company from which you ordered the door closer, often even inexperienced people can cope with this work.
Open position
In some cases, it may be necessary to hold the door open for quite a long time. Let's look at how to adjust the door closer so that the doors do not slam, but remain open.
Many door closer models have a special “hold open” function for this purpose. To set it to this mode, you need to open the door about 90 degrees and then tighten the special lock. After such simple manipulations, you will be able to leave the door open when swinging it open to the set degree. A special lock will work in the closer, which will hold it in this position for as long as necessary. When it is necessary to close the door, simply pull it towards you and the lock will be released. If the door is not fully opened, it will move as usual, without delay.
Additional functions of the closer are adjusted with screws specially designed for them.
How to properly adjust door closers with your own hands
To achieve smooth closing and opening of the door, it is necessary to install the closer correctly. And although there is nothing complicated about this, there are detailed instructions for carrying out this work. There are also a number of general points to consider:
- Adjusting the speed of closing the door structure.
This technology is distinguished by its simplicity. Immediately after installing the closer, it is necessary to check its operation. If it turns out that the closing speed is too high, then you need to turn the screw clockwise. This only needs to be done half a turn. Then check again. If the door closes, on the contrary, slowly, you will have to unscrew the screw. It is necessary to make such movements until you achieve the desired result. But you can see what kind of fittings there are for plastic windows and doors - Adjustment of aftershock.
In this case, everything happens in the same way as with the speed of movement of the door structure. But only this time it is necessary to adjust the speed and force of the door movement for the last 15-20 cm of its movement towards the frame. In addition, it is important to consider that as the clap accelerates, the impact force also increases. - Adjusting the intermediate stroke
. To achieve ideal operation of the closer, it is necessary to configure it with the main stroke of the door structure. Although there are other options. For example, when the main closing speed of the door is very high, then by adjusting the bolt it is possible to reduce it halfway. The main task of this screw is to hold the door leaf in the required position. Also, using a screw, it is possible to adjust a slight delay in the door structure. This means that when the door is opened, it will stand still for a few seconds and then close itself.
It is only important to know what installation options exist:
- On the side where the hinges are located.
- On the side opposite to the hinges.
- Parallel installation method. It is characterized by the use of a special corner for installation on the side opposite the hinges.

Diplomat
These door closers allow you to achieve high-quality protection of the door structure, ensuring trouble-free unlocking and locking of doors. There are many Diplomat models that allow you to achieve uninterrupted opening and closing of the door structure. Thanks to the wide range, everyone can choose the right product for themselves, with which they can achieve reliable operation of the door under specific operating conditions.
Diplomat
The process of adjusting the Diplomat closer can be done with your own efforts. To do this, you must adhere to the following recommendations:
- Setting the tension spring. When this step is completed, it is possible to make the opening of the door structure easier and freer. This task can be accomplished if you use an adjusting nut.
- Correction of closing speed and opening delay. This function is not present in all models of Diplomat door closers.
- Adjusting the speed of opening and closing the door. This can be done using a control valve.
But what is the best fittings for plastic windows, you can see
How to make adjustments
Depending on what we want to do with the door (slow down, speed up), there will be a sequence of actions. There are a total of two screws on the door closer on the side panel. The first top one is responsible for the speed of the canvas slamming. And the lower one is responsible for the speed of movement of the sash after it is fully swung open.
First you need to completely open the canvas and let it slam shut on its own. Monitor the speed of movement of the sash and its noise and sharpness when closing. Does the sash hit the frame hard? If yes, then you need to adjust the whole process.
So, in order to increase the speed of movement of the blade when closing, we adjust the lower screw. Do we want to increase speed? Turn the screw counterclockwise. Let's check. As a rule, it is enough to turn the screw half a turn. This is often enough. After adjustment, we check the operation of the door. If everything suits you, we leave it as is. If the door moves too quickly, turn the screw in the opposite direction a quarter turn. And accordingly, if we want to reduce the speed of the web, then turn the screw clockwise.
Now we are working on the finishing touches. If the door hits the frame hard when closing, turn the top screw. Try turning it half a turn and again track the speed of the clap. If everything is fine, leave it as is. If the door does not tighten tightly, then loosen the screw a little. The door should fit into the frame evenly, moderately tightly, without a strong bang, and especially without distortion. By turning the screw you can achieve the desired position of the sash.
By the way, when adjusting the speed of the blade, you can set it to the fully open position if necessary, for example, when moving and carrying large items back and forth. To do this, open the door completely and turn the bottom screw clockwise. It will remain in the open position for the required period of time. Then return the adjusting screw to the reverse position.
Please note that if the door is clearly skewed and does not fit tightly into the frame, you should not try to straighten it yourself. Here you will need the help of a professional who will find out the cause (deformation of the canvas or imbalance of the hinges) and eliminate it.
