Method 1:
It is suitable for door closers with its own force adjustment function. There is a hexagonal force adjustment hole on the rear end of this door closer. Adjusting the force adjustment hole with a hexagonal wrench can change the strength of the door closer. The intensity increases, and vice versa. Different product models have different adjustment circles and changes in strength, which are explained in detail in the installation manual of Fulda door closers.
Method 2:
There are generally two installation sizes in the installation manual of the door closer, which are the installation size of 120 degrees and the installation size of 180 degrees. When installed, the force of the door closer becomes smaller.
Method 3:
The door closer can also adjust the strength of the door closer by adjusting the installation position of the support on the connecting rod. The angle formed by the connecting rod and the main arm is inversely proportional to the strength of the door closer, that is, the connecting rod and the main arm are formed. The larger the angle, the smaller the force of the door closer, and vice versa.
