3, closing delay function - mainly reflected in the closing speed, generally from the largest point of view to 75 degrees, mainly to extend the speed of the door in order to slow down the small slow through the door.
4, the closing force can be adjusted - can be used in the door with a wide range of doors on a wide range of different doors to install, and because of environmental reasons to close the door more resistance. Random stepless adjustment can be satisfied with the closing force, especially in the coastal city, travel and other affected by the wind and closing resistance (the door of the force) often change the place.
5, damping reset function temporary shutdown performance (vertical door closers) - in the open any angle, turn off the speed control valve should be able to temporarily suspend the damping reset function.
6, safe and fast super damping off performance (vertical door closers) - in the process of closing any angle suddenly exert force, should be able to quickly and safely shut down.

2) Depending on the closing force size, the closing force can be changed by reversing the connecting seat by 180 ° or by changing the connection position between the connecting rod and the connecting seat. Adjust the distance between the connecting rod and the hinge centerline of the door, the smaller the closing force of the door closer, the greater the strength.
3) Determine the position of the mounting screw according to the position indication on the mounting plate, then drill and tapping.
4) Install the door closer with screws.
5) Install the fixed connector.
6) Install the drive plate with screws.
