Hydraulic Door Closer Replacement

はじめに

Replacing a hydraulic door closer is fairly simple with a little help, and adjusting it is even easier. This guide will help you identify if you need to replace your hydraulic door closer or if it just needs to be adjusted. Replacing your hydraulic door closer is important because over time hydraulic door closers will loose their functionality and cause your door to slam. A slamming door can cause unnecessary damage to your door. The whole process is simple and easy when you have a guide to help you. All you need to know is how to use a screwdriver and an Allen wrench to adjust, or replace, the hydraulic door closer. There are two main safety risks. The first one is pinching yourself on the door while you are installing the hydraulic door closer. The second one is a falling risk if you use a ladder to install the hydraulic door closer.
