Door closer maintenance

- Mar 26, 2019-

When the newly installed door closer is in use for a week or so, all the screws should be checked for tightness. The door closer should be inspected regularly after being put into use. The contents of the inspection are: whether the mounting screws are loose or missing, whether the connecting arm rubs against the door or the door frame, whether the door body is deformed and loosened, the buffering effect of closing the door, and the support guiding Whether the pieces leak oil, etc.
