Function and Usage of Door Closer
When the door closer is installed, test two stage speeds to close door. If the door is closed in appropriate speed, no need to regulate.
Regulate two stage speeds. The weight of each door is different, so we have to regulate two stage speeds of closing the door via rotating the B end of the door closer. Clockwise, speed up, counterclockwise, speed down.
For door sizes difference, the length of the door closer can be adjusted.
Keep the door open by pulling A end to the bottom.
