Hydraulic door closers are used to automatically close doors. They are effective in minimizing energy transfer and preventing room heat loss as well as preventing the annoying noise of a door slamming. Hydraulic door closers are attached to the door and the upper or lower portion of the door adjacent to the door hinges. Below are the materials you need as well as the instructions on how to adjust hydraulic door closers.

Step 1 - Locate the Spring Cartridge

Look for the adjustment screws on the spring cartridge of your hydraulic door closer. Determine if the adjustment screw is a flathead or a Phillips screw and have the appropriate screwdriver in hand. Use the ladder if necessary.

Step 2 - Determine and Adjust the Door Speed

Determine if you need to increase or decrease the pressure on your hydraulic door closer. If your door slams or closes too fast, decrease the hydraulic pressure by turning the adjustment screw clockwise. If your door is opening too slow, increase the hydraulic pressure of your door closer by turning the adjustment screw counter-clockwise.

Step 3 - Test the Door

Close and open the door a couple of times. Make the necessary adjustments by turning the adjustment screw of your hydraulic door closer either clockwise or counter-clockwise as needed. Once your door fully and smoothly closes, then you have successfully adjusted your hydraulic door closer to its appropriate setting.
