It is possible that the door closer is defective when the door is closed loudly or when it is hardly closed. In addition to how to adjust it, it also discusses cases where it is better to replace it with a new one.
What is a door closer?Can you adjust it yourself?
A ‘door closer’ is a part attached to the top of the door. The one attached to the outside of the door is called a “standard type” and the one attached to the inside is called a “parallel type”. If there is a door closer inside the front door, it is parallel.
Roles.
I don’t usually care, but the reason why I close the door slowly after opening it is because of the door closer.
If there is no door closer, the open door closes vigorously and the door or wall is damaged. And you might get hurt if your hands get stuck. It’s an essential part from the point of view
of accident prevention.
- If there is a problem.
- Oil is leaking.
- I can hear a whining sound.
- It closes faster.
- It doesn’t close easily, etc.
This phenomenon occurs when there is a problem with the door closer. Details will be explained later, but there are cases where it is easier to adjust than expected except for oil leakage.
Also, there are cases where adjustment can be done when “I want to close it a little faster” even if there is no problem. Adjustment may be difficult, but it’s easy so remember it won’t hurt.
How to adjust the door closer by case.
Let’s see how to adjust the door closer by case. Also, the position and detailed method of the part may vary depending on the manufacturer or model number. Let’s check the instruction manual or the manufacturer’s website as well.
I can hear a strange sound.
If the screws of each part’s interlock are loose, fasten them with a screwdriver.
If it is not loosened, lubricate the interlock part of each part.
When you hear a strange noise from the door closer, check the screw first, and if it is not loosened, lubricate it.
I want to close late.
- Turn the valve to adjust the speed of the main body.
- Attach the arm and the link again.
The valve for adjusting the speed is on either side of the door closer. If you use a driver or something to turn it into a hiragana ‘no’, it will be slow, so let’s adjust it.
Control valves may vary in number depending on the manufacturer and model number, and may not be operated unless it is a dedicated spanner. You can check with the door maker when you don’t know or when it’s difficult.
Also, there is a possibility that there will be a problem with the way to install it when it gets faster a little before the door closes completely.
In that case, it may be solved by re-fitting the arm (door part) and link (door frame part).
In the case of a parallel door closer attached to a normal door, it is normal for the link and the door to be parallel when closing the door. When it’s out of order.
- Unlink the arm and the link.
2. pull the arm forward.
3. Make the link and the door parallel.
4.Connect the arm and the link.
Let’s fix it again with this method.
I want to close quickly.
If you want to do it fast, you can turn the valve to adjust the speed in the opposite direction.
The door doesn’t stop.
1.Loose the stop screw.
2.Open the door to the place where you want to stop.
3.Fasten the stop screw.
Here’s what I want you to try when the function to stop with an open state doesn’t work. The stop screw is often on the link side, so let’s check it.
