    1) Usually there are installation templates in the instructions provided with the door closer, so first read the instructions and determine the installation position according to the direction of the door, the strength of the door closing and the installation size between the door closer fuselage, the connecting seat and the door hinge.

    2) According to the requirement of closing force, the closing force can be changed by reversing the connecting seat 180 degrees or changing the connecting position between the connecting rod and the connecting seat. The larger the distance between the adjusting connecting rod and the center line of the door hinge is, the smaller the closing force of the door closer is and vice versa.

    3) Determine the position of the installation screw according to the position indication of the installation template, then drill and tap.

    4) Install the door closer fuselage with screw.

    5) Install fixed connection seat.

    6) Install drive plate with screw.

    7) Adjust the adjusting rod to 90 degrees with the door frame, and then connect the connecting rod with the driving board.

    8) Don't forget to install a plastic cover, which can be used to catch the leakage of hydraulic oil from the door closer.

    9) After installation, check whether the fixing screw is tightened or not, and there should be no loosening or unstable phenomenon. Open the door to the maximum opening position and check whether the hinge arm of the door closer collides or rubs with the door or the door frame.

    10) Adjust the closing speed of the door closer according to the need. Usually the door closer has two speed regulating (throttle valve core) screws. The upper adjusting screw is the first closing speed adjusting screw, and the lower adjusting screw is the second (usually 10_) closing speed adjusting screw.
