How to adjust the door closer - the subtleties of the

For ease of use of interior and entrance doors, many of them are equipped with closers. However, for a long service life of the device, it must be periodically inspected and, if necessary, repaired. The article examines in detail how to adjust the door closer, the nuances of the work.

Types of closers

To determine how to adjust the door closer, you should get acquainted with their types and features.

The door closer is a special device that helps regulate the process of moving the door leaf, making its closing more smooth, without abrupt and noisy dead end. If necessary, the design holds the door in the open position.

By design features mechanisms are:

• Cam Slide. The device provides a smooth sliding canvas, installed in the door of a small mass.

• Toothed lever. This is the most used type of mechanism in which the movement of the spring carry gears. They can be used for high-weight doors with combination locks.

By way of mounting the product are:

• Overhead. These are the most simple to handle designs, whose operation is corrected by several valves or screws located on the panel of the box. The allowable speed is regulated by the manufacturer.

• Outdoor. Are regulated quite simply, differ in fastening not in the upper part of the door, but below. Such models are mainly used when arranging entry in offices and public institutions.

• Hidden. It is rather difficult to adjust such structures with your own hands, they are hidden in the floor or inside the door leaf, which makes access to them much more difficult.

The need for adjustment

There are several reasons due to which adjustment of parameters of such devices is required.

These include:

• Duration of service work closer.

Only high-quality service during the entire period of operation increases the service life of the product.

Tip: It is necessary at least once or twice a year to inspect the door closer, and if necessary, fix minor problems. Especially when changing seasons.

• Significant change in climatic conditions in winter and summer. Most of the closers work with oil filling, and any liquid can change its state from fluctuations in ambient temperature:

1. in winter, oil becomes more viscous, which slows down the movement of the door;
2. In the summer, the process is reversed.

Therefore, when changing the season, it is recommended to adjust the door closer to the desired level.

• Correction of the device when a problem is detected or the choice of the necessary settings for its operation.

Door closer adjustment понадобится при торможении двери или ее слишком быстром, резком и с рывками закрывании, полотно долго не притягивается.

• It is more difficult to resolve the issue when the device is out of order.

In this case, a simple adjustment of the door closer with your own hands may be ineffective - you will need to carry out additional repair measures.

• Setting the function of the closer during the initial installation. In this case, it is necessary to carry out adjustment in accordance with the requirements specified by the instruction manual.

What to avoid

Before proceeding with the adjustment of the door closer, it is necessary to know what limitations are possible so that the adjustment of the product functions does not become fatal for it.

These include:

• It is impossible to turn the screw from the zero point more than two turns, otherwise oil leakage may occur, which negatively affect the work of the closer.
• We can not allow distortions in the design, it can quickly break.
• Closing the door, you can not put a lot of pressure on it.
• You should not prop up the door leaf in the half-open position, but use a special function.
• It is forbidden to hang heavy objects on the door, this can lead to a distortion of the structure.

Tip: Following these recommendations, you can adjust the door closer. To extend its uninterrupted operation, to preserve the functionality of the device, its timely adjustment is required.

Door closer adjustment

Tip: To perform the adjustment of the device you can not unscrew the fully adjusting screws.

During the adjustment process is usually responsible hydraulics. If the adjustment blades are unscrewed more than two turns, oil will start flowing out of the hole, which will be pumped under pressure. At home, refueling everything back will not work.

To better understand the essence of the issue, you can get acquainted with the video in this article, which tells about the adjustment of the closers.

During the process of setting up the mechanism:

• Adjusting screws should turn a little: even the extra half-turn of the screw can lead to serious changes in the speed of movement of the door.
• Turning the screw clockwise increases the speed of closing the doors, while counter-clockwise it slows down.

After finding out the specifics of the adjustment rules, you can begin to decide how to loosen the door closer, adjust the device to work correctly?

Select door speed

The door closer has several functions, each of which is adjusted in a simple way. One of the important points is the adjustment of the speed of movement of the front door, how quickly it will close and open.

In the standard overhead models on the case there are two screws, the first one is designed to adjust the speed, but it rotates a limited number of times.

• Screw 1 - to adjust the speed of the blade.
• Screw 2 - to select the speed of the hangover.

By adjusting the spring tension level, it is possible to weaken or make the door closer work more rigid. From the direction of the scroll you can tighten the spring or release, which will give the canvas a more free move.

Tip: To adjust the speed, it is enough to make one turn of the screw so that the device does not leak and does not leak oil.

Adjustment of dokhlop

Adjusting the door closer, it comes to life, allows you to achieve a smooth closing of the blade, leaving a small gap before it closes completely. This mechanism provides a better fit of the blade to the door frame.

To set up a dohlop correctly, you need:

• Turn the second screw located on the closer body.
• When it remains about 10-15 °, until the door is completely closed, a slowdown is triggered, and the canvas is pulled to the end.
• The screw regulates the speed of this movement.

Adjustment of the additional stroke

The ideal option is to set up an intermediate move in “unison” with the main one, but there are other options. The purpose of the additional screw is to hold the door leaf in the desired position.

For example, if necessary, bring furniture to an apartment or house. To do this, the doors are opened to the desired position, and the screw is tightly tightened with a screwdriver. This effect can be achieved only when the door is opened at least 90 °.

In the door closer, a special retainer is activated, holding it in this position for as long as necessary. If you need to close the door, you just need to pull it towards you, and the fixation will be removed. If the door is not fully opened, its movement will be without delay, the same as usual.
