Third, Shunhui door lock maintenance

1. The transmission part of the lock body should always keep lubricant to keep its transmission smooth and prolong its service life. It is recommended to check once every six months or once a year to check whether the fastening screws are loose and ensure fastening.

2. When the lock head is in use, a little graphite powder or pencil powder can be put into the lock core groove regularly (half a year or a year) or when the key is not inserted smoothly, so as to ensure the smooth insertion and removal of the key. However, it is forbidden to add any other oil for lubrication, so as to avoid the grease sticking to the marble spring, which will make the lock unable to turn and open.

3. Always check the fit clearance between the lock body and the lock plate, and check whether the height of the lock tongue and the lock plate hole is appropriate. The best fit clearance between the door and the door frame is1.5mm-2.5mm. If any change is found, adjust the position of the hinge or lock plate on the door. At the same time, pay attention to the thermal expansion and cold contraction caused by seasonal changes to ensure that the gaps between the door and the frame, the lock body and the lock plate are reasonable and ensure the smooth use of the lock.
