Is your door closer no longer working as it used to? Perhaps it’s time to adjust it or switch to a soft door closer.
Adjusting a door closer can be easy if you have the right tools and knowledge of how the process works. Before you start, check first if there’s any leak from the door closer components.
Leakage can mean that the seals are damaged, and the door closer may have to be replaced entirely with help from your door closer supplier.
Most door closer adjustments are done by adjusting screws on the hydraulic valve. Here are some tips on adjusting the door closer tension.
- Familiarise yourself with the hydraulic valve components. Hydraulic valves usually have three parts. First is the backcheck, which keeps the door from opening too quickly and hitting objects. It works by slowing down once it reaches a certain degree during the opening cycle. Next is the sweep or main speed that’s usually in the middle and controls the door once it’s nearing its latching point. And last is the latching or closing speed, which is often near the hinge and functions as the door reaches its latching point.
- Be careful so as not to void the manufacturer warranty. It’s time to take out a ladder so you can inspect the valves closely. If you cannot see the valves, then you may have to remove the cover. If the door closer has fasteners, loosen the fasteners first to slide the cover. The cover can either be plastic or metal. Be careful so as not to remove it completely. Otherwise, it can result in leakage and void warranty from your automatic door supplier.
- Make small turns when adjusting screws. If you want your door closer to move more slowly, you may need to move the screw clockwise. If you need it to move faster, then you need to move the screw in a counterclockwise direction. Even small turns can already make a significant difference in the speed of your door closer. Try to start with just ⅛ of a turn. After every adjustment, get off the ladder and see the changes on your door closer. If you want it slower or faster, make another small adjustment accordingly. Keep testing, and be sure to clear the way when you do so.
- Repeat testing at least 10 times. Even if you see the door closer move to your desired speed, keep testing at least 10 times. Don’t stop until you get the consistent speed each time. If it only goes well at one time, then you’ll need to make further adjustments on the door closer. But if it moves at the right speed at all your tests, then you’re done adjusting.
When adjusting the tension on a door closer, be sure to check the warranty and manufacturer instructions. Contact your door closer supplier as well for questions or further assistance.
If you’re not confident about handling the task, leave it to experts to ensure everyone’s safety and keep your product warranty intact. Consider asking about soft door closers too so you no longer have to worry about the door banging or changing speeds.
